00:00:00And we are ready to go!

00:00:03The Nile crocodile goes much faster than the hippopotamus.

00:00:06It can go upstream and its body is designed to swim in rapids.

00:00:11It weighs as much as two refrigerators and is considered the heaviest reptile on the planet.

00:00:17It can swim up to 35 km per hour.

00:00:20The hippopotamus does not really know how to swim.

00:00:23It is content to walk on the bottom and push itself on the big rocks it finds.

00:00:27It can close its nostrils to slide a little underwater.

00:00:31But it lets itself be distanced by the crocodile.

00:00:34The crocodile reaches the shore and starts running through the field.

00:00:38But be careful, the hippopotamus catches up with him at full speed.

00:00:42Even if it is huge, the hippopotamus can sprint faster than a human.

00:00:46Despite the advance taken by the crocodile, the hippopotamus is much faster than him on the ground.

00:00:51And he crosses the finish line. He won!

00:00:55Beep beep! Here is a big geocuckoo.

00:00:58But what is running away like that?

00:01:00Ah yes, it's this coyote.

00:01:02But be careful, it catches up with you.

00:01:04The big geocuckoo can run up to 30 km per hour,

00:01:07even a little faster when it is really hungry.

00:01:10And despite what we see in cartoons, the coyote is actually twice as fast as him.

00:01:15But the Looney Tunes version is still more fun.

00:01:20On line number 1, coming straight from South America,

00:01:23we have the hyper-slow sloth.

00:01:26And next to it, on line 2, we have an ordinary garden snail.

00:01:30And here we go!

00:01:32For the race of the slowest animal in the world.

00:01:39The maximum speed of the sloth being 0.3 km per hour,

00:01:43it is not surprising that it is compared to a moving giant ear.

00:01:47The snail has made a good start.

00:01:50It can cross a small neighborhood at a speed of 50 m per hour.

00:01:54This invertebrate has only one foot,

00:01:56which is covered with a layer of protective sludge.

00:01:59I'm not quite sure, but I think the sloth is ...

00:02:02always in the same place.

00:02:04It fell asleep, and it may last,

00:02:06because a sloth can sleep up to 15 hours a day.

00:02:09It sleeps more than half its life.

00:02:12Oh, the snail has left its sunny area to go to the shade.

00:02:16It is still too early to know who will win this fierce race.

00:02:20A grizzly can easily distance a human.

00:02:23If you are preparing something a little too delicious for a picnic,

00:02:26expect to give up your meal.

00:02:28The fastest speed a human can sprint is 45 km per hour.

00:02:33Record established, of course, by Usain Bolt.

00:02:36So he would probably be able to escape in time.

00:02:39But if you are slower than him, then you may have problems.

00:02:43In a sprint against a grizzly, it will necessarily beat you.

00:02:47But of all the bears, which is the fastest?

00:02:50The white bear, the grizzly, the brown bear,

00:02:53the crocodile bear or the cute little panda?

00:02:56On your marks, get set, go!

00:02:59The tension is palpable.

00:03:01The grizzly and the brown bear are neck and neck.

00:03:04A brown bear can run as fast as a grizzly.

00:03:07The crocodile bear is the smallest bear in the race.

00:03:10He is about 2 meters tall or long.

00:03:13In short, he can't keep up.

00:03:15The polar bear has made a good start,

00:03:17but he doesn't have the endurance of the grizzly or the brown bear.

00:03:20The grizzly takes the lead.

00:03:22No, it's the brown bear, the grizzly.

00:03:24But wait, where's the panda?

00:03:26What is he doing?

00:03:28I don't think he's interested in the race,

00:03:30but he's too cute.

00:03:32He just finished his third bamboo stem.

00:03:34A panda can eat up to 13 kilos of bamboo a day.

00:03:37That's a lot.

00:03:39But that's it, he's found a shortcut

00:03:41and he's sweeping the hill.

00:03:43He passes in front of the grizzly and the brown bear.

00:03:46It's over, the panda won.

00:03:48Sorry, bears.

00:03:50We all know that the panda is not really fast.

00:03:52It's even one of the slowest bears.

00:03:54However, if you see a panda sweeping a hill in your direction,

00:03:57run!

00:03:59A Boeing 747 can reach a maximum speed of about 1,000 km per hour.

00:04:03The fastest bird is the grey-headed albatross.

00:04:06It can fly up to 130 km per hour

00:04:09and stay in the air for about 10 hours without landing.

00:04:12The pilgrim falcon is faster,

00:04:14but only spiked to catch a prey.

00:04:16Watch out for the pigeons.

00:04:18Wow!

00:04:20The big planes take time to gain altitude,

00:04:22but it only takes a few seconds for the albatross.

00:04:24He's in the lead,

00:04:26but a few minutes later,

00:04:28back to the race.

00:04:30The lazy one has woken up,

00:04:32all the better.

00:04:34However, he has just raised an arm to reach this branch.

00:04:37The snail is still trying to pass this big rock.

00:04:40The lazy ones spend the clearest time

00:04:42as immobile as possible

00:04:44to avoid becoming someone else's breakfast.

00:04:47Not great for racing.

00:04:49But what's going on?

00:04:51A third player enters the race.

00:04:53It's the Galapagos turtle.

00:04:55Its powerful front legs

00:04:57attract this real living tank.

00:04:59It is four times faster than the garden snail.

00:05:02It's getting interesting.

00:05:04Here is a race that will last a century.

00:05:07The turtle runs and avoids all obstacles.

00:05:09Nothing can stop it.

00:05:11Hey, no cheating, lazy one.

00:05:13Stop throwing branches from up there.

00:05:15During this time, underground,

00:05:17a toad digs.

00:05:19It can eat its own weight daily in earthworms,

00:05:21and it digs about five meters per hour.

00:05:23The American bullfrog

00:05:25is the animal that digs the fastest in the world,

00:05:27and it is also very fast on the ground.

00:05:29It can almost equal the speed of a human

00:05:31in a good day.

00:05:33The bullfrog therefore wins this tunnel race

00:05:35quite easily.

00:05:37Too bad the toad can't see where it's going.

00:05:39Toads are not really blind.

00:05:41They just have a very bad sight,

00:05:43and they are daltonian.

00:05:45And since they can't wear glasses...

00:05:47Ah, the famous cheetah.

00:05:49It crosses the savannah at full speed.

00:05:52I am the fastest earthworm

00:05:54in millions of years.

00:05:56I'm the boss.

00:05:58The fastest recorded cheetah

00:06:00was a sprinter named Sarah.

00:06:02At 11 years old, she ran the 100 meters

00:06:04in less than 6 seconds.

00:06:06A cheetah can reach 130 km per hour

00:06:08if it sees something tasty.

00:06:10Sarah grew up in an American zoo,

00:06:12and she was one of the first cheetahs

00:06:14to have a puppy as a friend.

00:06:16Alex and Sarah, friends for life.

00:06:18But just above Sarah

00:06:20passes a very small bat,

00:06:22and it puts Sarah on the spot.

00:06:24The Brazilian mollusk

00:06:26can reach 160 km per hour.

00:06:28It's the fastest mammal

00:06:30on the planet.

00:06:32Now let's activate our zoom.

00:06:34Our first competitor

00:06:36is the Australian sea sandal.

00:06:38It runs at a speed of 10 km per hour.

00:06:40It may seem small,

00:06:42but compared to its size,

00:06:44it goes at lightning speed.

00:06:46It's like a human running as fast

00:06:48as a high-speed train.

00:06:50In the inner corridor

00:06:52is the Saharan silver ant.

00:06:54They are stronger when they work together.

00:06:56But even alone,

00:06:58they can beat records.

00:07:00They can lift hundreds of times

00:07:02their own weight and sprint like never before.

00:07:04If Usain Bolt can do 4 strokes per second,

00:07:06the silver ant can do 50.

00:07:08Scientists have even discovered

00:07:10that they gallop literally

00:07:12when they reach their top speed.

00:07:14And here is our last competitor,

00:07:16the fastest animal on Earth.

00:07:18It's a tiny macaw

00:07:20that is no bigger than a sesame seed.

00:07:22And it runs almost twice as fast

00:07:24as the sea sandal.

00:07:26If we brought it back to our size,

00:07:28this microscopic animal

00:07:30would beat everything on the planet.

00:07:32It would even surpass the wall of sound.

00:07:34Let's go back to our slower ones.

00:07:36Are they done yet?

00:07:38The turtle is in the lead.

00:07:40The snail has finally passed this big rock

00:07:42and the lazy one is ready

00:07:44to catch a second branch.

00:07:46The turtle is less than a meter

00:07:48from the finish line.

00:07:50Wow, I can't stand this suspense anymore.

00:07:52But I think I have time

00:07:54to go and have a coffee.

00:07:56If you think your parents

00:07:58have been too hard on you,

00:08:00maybe with this list of animals

00:08:02you will understand

00:08:04that they may not have been so bad.

00:08:06The female of the horse

00:08:08has a gestation period of about 1 year.

00:08:10It may seem terribly long,

00:08:12but for elephants,

00:08:14it's nothing.

00:08:16They carry their babies

00:08:18on their backs.

00:08:20Unlike other animals

00:08:22who prefer to rest

00:08:24while waiting for their babies to arrive,

00:08:26for males,

00:08:28pregnancy is synonymous with celebration.

00:08:30As soon as the female is pregnant,

00:08:32she goes around the herd

00:08:34and mates with each stallion.

00:08:36This may seem absurd to you

00:08:38since she is already pregnant,

00:08:40but there is a reasonable explanation.

00:08:42Horses are rather proud

00:08:44and aggressive towards their rivals.

00:08:46The risk of hurting the baby

00:08:48will be zero.

00:08:50The real intention of the males

00:08:52is to protect the stallions

00:08:54by making sure that no male

00:08:56knows who the real father is.

00:08:58Isn't that ingenious?

00:09:00So the males will be at the bottom of our list.

00:09:02Everyone knows

00:09:04that the female of the cuckoo

00:09:06abandons her babies before hatching.

00:09:08She simply lays her eggs

00:09:10in the nest of other birds

00:09:12and leaves forever.

00:09:14Although it is difficult

00:09:16to tell the difference

00:09:18between the eggs,

00:09:20all the birds end up

00:09:22hatching in the same way.

00:09:24During this time,

00:09:26the cuckoos enjoy their life

00:09:28without attachment.

00:09:30Alas, the problems

00:09:32quickly arise in the nest.

00:09:34The little cuckoo

00:09:36sows chaos in his nesting family.

00:09:38He grows faster

00:09:40and hatches earlier

00:09:42The female of the cuckoo

00:09:44is both a careful mother

00:09:46and a furious mother-in-law

00:09:48who would even terrify the stallion.

00:09:50Cuckoos are usually monogamous,

00:09:52but sometimes they have relations

00:09:54outside the nest.

00:09:56When this happens,

00:09:58a female can often discover

00:10:00the masters of her companion

00:10:02and she will not hesitate

00:10:04to destroy their nest.

00:10:06Why? To make sure

00:10:08that the male cuckoo

00:10:10does not attack the female.

00:10:12The cuckoos

00:10:14take care of their young

00:10:16during their first two weeks.

00:10:18We can not say

00:10:20that these creatures

00:10:22are the worst mothers

00:10:24of the animal kingdom.

00:10:26During this short period,

00:10:28they keep their children

00:10:30close to them,

00:10:32the cuckoos,

00:10:34and feed them 24 hours a day.

00:10:36But after that,

00:10:38they will not be able

00:10:40to fly or protect themselves.

00:10:42It would take them at least

00:10:44two months to acquire

00:10:46all these skills.

00:10:48They spend their time

00:10:50waiting, losing weight

00:10:52while trying to avoid

00:10:54ending up in the mouth

00:10:56of a predator.

00:10:58It is not surprising

00:11:00that only a third

00:11:02of cuckoos

00:11:04manage to survive

00:11:06and that the female

00:11:08confuses her offspring

00:11:10with her dinner.

00:11:12No one knows exactly why,

00:11:14but scientists have

00:11:16developed several theories.

00:11:18Some think that she does this

00:11:20to fill up her energy

00:11:22after giving birth.

00:11:24Others say that cuckoos

00:11:26can feel stressed

00:11:28and threatened

00:11:30by too large a range.

00:11:32This act would therefore

00:11:34make it difficult

00:11:36to feed them well.

00:11:38All or nothing is probably

00:11:40the favorite motto

00:11:42of cuckoos.

00:11:44They usually have

00:11:46two or three cuckoos

00:11:48at the same time.

00:11:50But if for some reason

00:11:52a mother cuckoo

00:11:54has only one cuckoo,

00:11:56she will be able to

00:11:58abandon it in the hope

00:12:00of having a larger range

00:12:02It is quite the opposite

00:12:04with pandas.

00:12:06Surprisingly,

00:12:08these adorable cuckoos

00:12:10are quite negligent parents.

00:12:12Mothers usually have twins,

00:12:14but they prefer to take

00:12:16care of only one of them.

00:12:18She sleeps on the throne

00:12:20and has the strongest baby on the throne.

00:12:22During this time,

00:12:24the weakest will be abandoned

00:12:26and will have to survive

00:12:28by her own means.

00:12:30Even the pandas living in the water

00:12:32obey this instinct.

00:12:34Fortunately,

00:12:36the employees of the animal parks

00:12:38feed all the cuckoos without distinction.

00:12:40Although monkeys

00:12:42generally have the reputation

00:12:44of being attentive parents,

00:12:46these cute moustached creatures

00:12:48make an exception to the rule.

00:12:50After a period of gestation

00:12:52of about five months,

00:12:54the female of the tamarin

00:12:56gives birth to twins.

00:12:58She will completely ignore

00:13:00their cries and calls.

00:13:02It is even possible that a mother

00:13:04violently throws her babies

00:13:06from the top of her branch.

00:13:08Who knows what is hiding

00:13:10in these little heads?

00:13:12But not all have such a cold heart.

00:13:14If a tamarin mother is well surrounded,

00:13:16has food and feels protected,

00:13:18it is likely that she takes

00:13:20good care of her offspring.

00:13:22But if no one looks at her

00:13:24or helps her,

00:13:26there is not much chance of survival.

00:13:28Although it seems that

00:13:30moustached tamarins

00:13:32would make excellent pets,

00:13:34experts say that these monkeys

00:13:36require more care than any other

00:13:38domestic animal.

00:13:40Above all, be careful

00:13:42that they do not push you

00:13:44from your branch.

00:13:46Rabbits are generally associated

00:13:48with cuddles and caresses.

00:13:50But in real life,

00:13:52they are not as sweet

00:13:54as their mother.

00:13:56And these cute little rabbits

00:13:58must learn to face

00:14:00the challenges of life

00:14:02by themselves.

00:14:04They only see their mother

00:14:06a few minutes a day

00:14:08during the summer.

00:14:10Scientists believe that

00:14:12rabbits abandon their offspring

00:14:14to deceive predators

00:14:16and keep them away.

00:14:18Of course, this method

00:14:20does not offer a 100% guarantee.

00:14:22And where is the landmark?

00:14:24Well, it is recommended

00:14:26to isolate the mothers

00:14:28of the males

00:14:30while they raise their babies.

00:14:32Unlike horses,

00:14:34rabbits will probably

00:14:36not hurt the little ones.

00:14:38But they could again

00:14:40fertilize the rabbit,

00:14:42even if it has just given birth.

00:14:44Reptiles are not known

00:14:46to be warm and attentive creatures.

00:14:48And their practical approach

00:14:50The 5 long-tailed rabbits

00:14:52do not do half the work

00:14:54in terms of self-protection.

00:14:56This species of Saurian

00:14:58will eat its own eggs

00:15:00if too many predators

00:15:02gather around its shelter.

00:15:04The mother will not make

00:15:06any effort to repel the danger.

00:15:08Her motto is perhaps

00:15:10« If I can't keep them,

00:15:12then no one will have them ».

00:15:14Once the threat is removed,

00:15:16she continues to live normally

00:15:18After about a month of incubation,

00:15:20the eagles are finally born.

00:15:22But their problems

00:15:24are just getting started.

00:15:26As the eggs are not all

00:15:28exactly the same age,

00:15:30they do not hatch simultaneously.

00:15:32And the competition between

00:15:34brothers and sisters

00:15:36can then be terrible.

00:15:38They will show themselves

00:15:40very aggressive

00:15:42towards each other.

00:15:44The older ones

00:15:46Three of the most majestic

00:15:48but also the most intimidating

00:15:50members of the animal kingdom.

00:15:52Could there be anything

00:15:54that intimidates these creatures?

00:15:56You may be surprised.

00:15:58Let's start with the king

00:16:00universally recognized

00:16:02of animals, the lion.

00:16:04Some claim that this big cat

00:16:06of the savannah is afraid

00:16:08of the most vital substance

00:16:10known to man.

00:16:12A little hint,

00:16:14Really? The lion would be afraid

00:16:16of water?

00:16:18No, it's a myth.

00:16:20Lions like to bathe,

00:16:22especially because it allows them

00:16:24to refresh themselves.

00:16:26This makes sense when we think

00:16:28of the climate in which

00:16:30these creatures must pass.

00:16:32Temperatures in a savannah climate

00:16:34range from 20 degrees to 30 degrees.

00:16:36We humans really want to go

00:16:38to the beach as soon as the weather is hot.

00:16:40So why should we expect

00:16:42to go to the beach?

00:16:44Especially if we consider

00:16:46that these creatures generally

00:16:48weigh between 127 and 190 kilos,

00:16:50twice the thickness of a fur coat.

00:16:52The irony of this myth,

00:16:54which stipulates that lions

00:16:56are afraid of water,

00:16:58is that they are actually

00:17:00excellent swimmers.

00:17:02The same goes for all the other

00:17:04big cats of these hot climates,

00:17:06such as tigers, leopards,

00:17:08jaguars and ocelots.

00:17:10This applies to felines

00:17:12such as wild cats, lynxes

00:17:14and snow leopards.

00:17:16They live in the cold biome

00:17:18of the alpine tundra,

00:17:20a rocky and mountainous area.

00:17:22Temperatures there

00:17:24go down to 1 degree.

00:17:26Once again,

00:17:28it is perfectly logical

00:17:30that these big cats of cold climates

00:17:32are afraid of water.

00:17:34Wetting their fur coat

00:17:36would reduce their chances

00:17:38of survival.

00:17:40But we will go much further

00:17:42to understand where the myth

00:17:44that lions are afraid of water

00:17:46comes from.

00:17:48In fact, there is a good chance

00:17:50that the reason is

00:17:52close to your computer screen

00:17:54right now,

00:17:56jumping everywhere

00:17:58and doing stupid things.

00:18:00It is true,

00:18:02we may have jumped

00:18:04a little too quickly

00:18:06but the cats mentioned above

00:18:08do not come directly from them.

00:18:10They have developed over millions of years

00:18:12from a single wild ancestor

00:18:14that still exists today

00:18:16in nature,

00:18:18the wild cat of Africa.

00:18:20As water is not abundant

00:18:22in North Africa and the Middle East,

00:18:24these cats have not been

00:18:26exposed to it much

00:18:28and as their descendants,

00:18:30they only appreciate it to drink it.

00:18:32As you probably see

00:18:34cats do not interact much with water

00:18:36in general.

00:18:38Fortunately for them,

00:18:40they do not need it.

00:18:42These domestic cats

00:18:44use their tongues

00:18:46to clean themselves.

00:18:48It is equipped with tiny hooks

00:18:50in the shape of hooks

00:18:52that help the cats

00:18:54to make the knots disappear

00:18:56and to keep their own fur.

00:18:58Very fragrant

00:19:00and in a generally impeccable state.

00:19:02Some cats love water

00:19:04and it is quite possible.

00:19:06Some cats even like to play with it,

00:19:08for example,

00:19:10the drops of the tap

00:19:12or the bubbles in your bath.

00:19:14There are specific breeds

00:19:16of domestic cats

00:19:18known to appreciate aquatic life

00:19:20more than others.

00:19:22The Turk of Van, for example,

00:19:24which is also known

00:19:26under the appropriate name

00:19:28of swimmer cat.

00:19:30This lake is located

00:19:32in the region where these animals

00:19:34have evolved.

00:19:36Now let's move on to a problem

00:19:38that a cat has absolutely

00:19:40nothing to do with.

00:19:42Have you ever heard

00:19:44of musophobia?

00:19:46Also known under the name

00:19:48of suriphobia,

00:19:50these two words

00:19:52designate a fear of mice

00:19:54and rats.

00:19:56There is a popular belief

00:19:58that if a mouse

00:20:00climbed into a pylon,

00:20:02it would be afraid of a creature

00:20:04that only measures 10 cm

00:20:06and weighs less than a few grams.

00:20:08How did this belief come about?

00:20:10Well, the basis of this rumor

00:20:12is the possibility

00:20:14that elephants are indeed paranoid

00:20:16about the idea that mice

00:20:18can climb into their trunks.

00:20:20If a mouse managed to do it,

00:20:22there would be a risk

00:20:24that it would cause irritation

00:20:26To be honest,

00:20:28this belief is also a myth.

00:20:30Researchers say

00:20:32that there is no concrete evidence

00:20:34that elephants are afraid of mice.

00:20:36Moreover, they say

00:20:38that the gigantic animal

00:20:40can sometimes be afraid

00:20:42of the sudden appearance

00:20:44of the little rodent.

00:20:46Experts also say

00:20:48that even if a mouse

00:20:50managed to get into the trunk

00:20:52of an elephant,

00:20:54it would be afraid of the breath of air.

00:20:56There is also evidence

00:20:58that in most cases,

00:21:00the animal is not disturbed

00:21:02by rodents and even allows

00:21:04mice to climb on its head

00:21:06and trunk.

00:21:08Researchers are sure

00:21:10that as long as an elephant

00:21:12is in good health,

00:21:14there is no other animal

00:21:16that it fears,

00:21:18simply because of its size.

00:21:20Thus, elephants are not afraid of water

00:21:22And if we are interested

00:21:24in the question of whether

00:21:26the bear has a legitimate fear,

00:21:28well, it would be counting

00:21:30on the best friend of man.

00:21:32Yes, bears feel quite uncomfortable

00:21:34when they are in the presence

00:21:36of dogs,

00:21:38despite a genetic relationship

00:21:40with them.

00:21:42When the two creatures meet,

00:21:44the dog is able to chase,

00:21:46intimidate, trap

00:21:48or oppose the bear.

00:21:50In fact, the elephant

00:21:52will try to avoid

00:21:54any confrontation with the dog.

00:21:56There is even a Finnish dog breed

00:21:58known as Kareli's Bear Dog.

00:22:00This species is specially used

00:22:02to hold on to large animals

00:22:04like bears.

00:22:06This dog has an excellent sense

00:22:08of direction, great flexibility

00:22:10and mastery of its body,

00:22:12courage, a good smell

00:22:14and perseverance.

00:22:16Does this mean that you can

00:22:18be absolutely calm and confident

00:22:20thanks to the presence of your

00:22:22faithful companion?

00:22:24Not really.

00:22:26Even if bears can be nervous

00:22:28in the presence of dogs,

00:22:30we must not forget their size

00:22:32or their power.

00:22:34The American black bear

00:22:36can reach a height of

00:22:38almost 2 meters

00:22:40and weigh up to 300 kg.

00:22:42If a bear mother has nowhere

00:22:44to go or if she feels

00:22:46so no one should ever

00:22:48experience this theory.

00:22:50Instead, if you plan

00:22:52to visit an unknown region

00:22:54with your dog one day,

00:22:56you should first familiarize yourself

00:22:58with the fauna that you could

00:23:00meet there.

00:23:02Because you never know what a bear

00:23:04will do when it notices you

00:23:06with your teddy bear,

00:23:08especially if you take into account

00:23:10their slight synophobia,

00:23:12which is the name given

00:23:14to the animal among the three

00:23:16cadors of the food chain.

00:23:18But isn't it strange that the dog

00:23:20that brings so much joy

00:23:22and comfort to many of us

00:23:24is also a rather puny creature

00:23:26to confront a bear?

00:23:28Well, all heroes don't wear a cape.

00:23:30Some simply wear fur and a collar.

00:23:32And while we're at it,

00:23:34why not take a look at what

00:23:36frightens our faithful furry companions?

00:23:38Have you ever wondered why

00:23:40your dog is uncomfortable

00:23:42The degree of fear

00:23:44differs for each dog,

00:23:46but it is the simple unpredictability

00:23:48of the thunder and lightning

00:23:50or strong detonations

00:23:52accompanied by fireworks

00:23:54that cause your dog's discomfort.

00:23:56The inability to understand

00:23:58what causes this deafening noise

00:24:00can cause your dog to tremble,

00:24:02to get his tail between his legs

00:24:04or even to run away from home.

00:24:06Another situation that can really

00:24:08frighten your faithful companion animals

00:24:10It can unfortunately become

00:24:12a nightmare for your neighbors

00:24:14because a common symptom of this fear

00:24:16is excessive barking.

00:24:18This fear can also cause problems

00:24:20closer to home.

00:24:22Have you ever wondered why

00:24:24your dog had messed up your sofa?

00:24:26These learning accidents are typical

00:24:28when a dog suffers from anxiety

00:24:30due to separation.

00:24:32But you can't stay angry at your dog for long,

00:24:34can you?

00:24:36Your best friend will catch up

00:24:38Incredible but true

00:24:40lazy dogs can hold their breath

00:24:42longer than dolphins.

00:24:44They slow down their heart rate

00:24:46so much that they can stay

00:24:48under the surface for up to 40 minutes.

00:24:50Unlike fish, dolphins and whales

00:24:52are aquatic mammals,

00:24:54which means they can't breathe underwater.

00:24:56When it comes to breathing,

00:24:58they are more like us than fish.

00:25:00They have lungs

00:25:02and breathe through a hole

00:25:04called the vent.

00:25:06They hold their breath

00:25:08until they can go back up to breathe.

00:25:10Dolphins can stay underwater for 10 minutes.

00:25:12A seal can hold its breath

00:25:14for 90 minutes.

00:25:16While the sea elephant holds the record

00:25:18among aquatic mammals

00:25:20and can stay underwater for 2 hours

00:25:22without having to go back up.

00:25:24There is such a tiny gill,

00:25:26even smaller than a pinhead,

00:25:28that it is almost the size of an amoeba,

00:25:30knowing that amoebas are composed

00:25:32of only one cell.

00:25:34Amoebas have the same parts of the body

00:25:36as the rest of the insects,

00:25:38wings, brain, eyes, etc.

00:25:40But it's a really microscopic version

00:25:42of an insect,

00:25:44as it is only 0.2 mm long.

00:25:46The smallest adult insect

00:25:48we know is a parasitic gecko

00:25:50with a very complex name.

00:25:52It's a mimaridae.

00:25:54Males don't have wings.

00:25:56They are blind and only measure 0.1 mm.

00:25:58It's no coincidence

00:26:00that each animal species

00:26:02has different colors and patterns.

00:26:04This is especially to help them

00:26:06distinguish themselves

00:26:08when they are looking for

00:26:10potential mating partners

00:26:12or to warn predators

00:26:14that they are venomous,

00:26:16hoping they understand the message.

00:26:18Then there are stealthy predators

00:26:20like tigers.

00:26:22It is very important for them

00:26:24to remain invisible

00:26:26because it makes all the difference.

00:26:28If their prey sees them coming from far away,

00:26:30they can't see them.

00:26:32For us,

00:26:34orange is a color used

00:26:36for things that must be very visible,

00:26:38for example,

00:26:40for safety vests

00:26:42or signaling cones.

00:26:44For the human eye,

00:26:46orange is generally distinguished

00:26:48in the environment.

00:26:50So if a tiger is heading towards you,

00:26:52you will easily spot it.

00:26:54But humans have a vision

00:26:56of the so-called trichromatic colors.

00:26:58To treat this light,

00:27:00the retina uses two types of light receptors,

00:27:02cones and cones.

00:27:04Cones can only distinguish

00:27:06the difference between light and darkness.

00:27:08They can't perceive colors.

00:27:10Our eyes rely mainly on cones

00:27:12when the light is low.

00:27:14Cones are responsible for the perception of colors.

00:27:16Humans have mainly three types

00:27:18for green, blue and red.

00:27:20This is why we call our vision

00:27:22trichromatic.

00:27:24Most humans see three primary colors

00:27:26as well as their color combinations.

00:27:28Great apes also have

00:27:30this type of vision.

00:27:32But most mammals that live on Earth,

00:27:34including cats, horses,

00:27:36deer and dogs,

00:27:38have a so-called chromatic vision of colors.

00:27:40Their retinas have cones

00:27:42for only two colors,

00:27:44green and blue.

00:27:46When humans get information

00:27:48only from their green and blue cones,

00:27:50they are considered daltonian

00:27:52because they can't, for example,

00:27:54see the difference between green and red.

00:27:56This situation is similar

00:27:58in terrestrial mammals.

00:28:00Deer are probably the prey of tigers

00:28:02much more often than humans.

00:28:04And they don't see tigers in orange,

00:28:06but in green.

00:28:08Green tigers would probably be

00:28:10more difficult to spot,

00:28:12which would mean more meat for tigers.

00:28:14But evolution has still decided

00:28:16to opt for orange

00:28:18because it is simply easier

00:28:20to produce such a color.

00:28:22It's because of the algae that grow there.

00:28:24And they can hold their breath

00:28:26for 40 minutes.

00:28:28The water around the poles can become very cold

00:28:30during certain periods of the year.

00:28:32Many fish live there,

00:28:34but when that happens,

00:28:36they have to migrate to survive.

00:28:38But there is a special group of fish

00:28:40native to the Austral Ocean

00:28:42near Antarctica.

00:28:44The temperatures there vary

00:28:46from minus 2 degrees to 4 degrees Celsius.

00:28:48Technically, it's below zero,

00:28:50but sea water salt

00:28:52keeps them from freezing.

00:28:54These fish can survive

00:28:56because they have a special feature

00:28:58called glycoprotein.

00:29:00It helps them stay at home

00:29:02because it acts as a kind of natural antifreeze.

00:29:04It's a protein

00:29:06that prevents ice crystals

00:29:08from forming in their blood

00:29:10and helps them to continue to circulate normally.

00:29:12Have you ever wondered

00:29:14how tiny animals like ants breathe?

00:29:16Try opening your mouth and throat,

00:29:18but at the same time,

00:29:20hold your chest and diaphragm still.

00:29:22The diaphragm is a muscular structure

00:29:24that separates the thoracic and abdominal

00:29:26cavities of all mammals.

00:29:28It normally expands when you breathe.

00:29:30If you do this,

00:29:32you can't hold your breath

00:29:34because oxygen will always find a way

00:29:36to enter your lungs,

00:29:38at least enough to meet your body's needs.

00:29:40But in general, when you breathe,

00:29:42the diaphragm actively pumps air

00:29:44into your body and out of it.

00:29:46In order to survive

00:29:48without the diaphragm doing it,

00:29:50you would need to have more than one throat

00:29:52and still be much smaller.

00:29:54Ants have 9 or 10 pairs of openings

00:29:56along the sides of their small bodies.

00:29:58They are called spiracles

00:30:00and each is connected

00:30:02to a series of branched tubes.

00:30:04It's a system similar to human lungs.

00:30:06Their blood does not transport

00:30:08the oxygen from these tubes to the rest of their body.

00:30:10Instead, the tubes

00:30:12diffuse this oxygen.

00:30:14This is why these branches

00:30:16directly touch the membranes of their cells.

00:30:18This can only work

00:30:20in really small animals.

00:30:22When the body is larger than 2 cm,

00:30:24these tubes are too long

00:30:26and cannot diffuse air quickly enough.

00:30:28There are several reasons

00:30:30why giraffes have a long neck,

00:30:32which, by the way,

00:30:34can reach a length of 2.5 m.

00:30:36At first glance,

00:30:38it seems that evolution

00:30:40has provided them with this neck

00:30:42because it is the softest part of the trees.

00:30:44It is an exclusive access

00:30:46that only other animals can dream of

00:30:48and giraffes do not have to fight

00:30:50for the best leaves.

00:30:52But over time,

00:30:54researchers have realized

00:30:56that this was not the only reason.

00:30:58They also think that the neck

00:31:00could be an important element

00:31:02when male giraffes

00:31:04start fighting,

00:31:06just as male antelopes

00:31:08use their teeth

00:31:10Some insects

00:31:12play hide-and-seek

00:31:14when there is a predator nearby.

00:31:16For example, in an experiment,

00:31:18scientists observed an ant

00:31:20in larval state.

00:31:22It was able to die

00:31:24for 61 minutes.

00:31:26How can this be useful?

00:31:28Well, let's say you are in a garden

00:31:30where you see a lot of identical bushes

00:31:32with fruits.

00:31:34You go to the first bush

00:31:36and you start picking

00:31:38But as you pick this bush,

00:31:40you have more and more trouble

00:31:42finding other fruits.

00:31:44And it's a little annoying

00:31:46because it takes a lot more time

00:31:48than at the beginning.

00:31:50So now you have to decide

00:31:52if you should stay there

00:31:54and try to find more

00:31:56or just go to another bush

00:31:58so that everything is easy and fast again.

00:32:00Assuming you are the predator

00:32:02and the predators are greedy,

00:32:04you will just try to eat

00:32:06This means that you will go to another bush

00:32:08and pick the fruits that are there

00:32:10then go to the next one, and so on.

00:32:12Researchers explain the same logic

00:32:14when it comes to birds and ant larvae.

00:32:16You are looking for something

00:32:18viscous.

00:32:20Many people tend to believe

00:32:22that snails are just limes

00:32:24with a shell.

00:32:26But even if they look a lot alike,

00:32:28they are completely different species.

00:32:30Limes do not need a protective shell

00:32:32because all their internal organs

00:32:34are located inside their viscous body.

00:32:36They can compress

00:32:38and enter

00:32:40difficult places to access.

00:32:42This is why we often find limes

00:32:44in the most improbable places

00:32:46like under the bark of trees

00:32:48or in tiny little holes

00:32:50or at the library

00:32:52pretending to study for exams.

00:32:54Snails, on the other hand,

00:32:56are very dependent on their shell

00:32:58and cannot survive without it.

00:33:00Unlike Bernard the hermit

00:33:02who grew up with a shell,

00:33:04snails are born with a shell on their back.

00:33:06Baby snails are also adorable

00:33:08with their fragile translucent bubbles

00:33:10which calcify and become

00:33:12larger and more resistant with age.

00:33:14Many internal organs

00:33:16of snails are also

00:33:18inside the shell,

00:33:20which means that if it is crushed

00:33:22or damaged, the animal will probably

00:33:24not survive.

00:33:26However, a snail can repair

00:33:28the small cracks in its shell

00:33:30and calcium secreted by its mantle.

00:33:32Turtles are very close

00:33:34to snails in this regard

00:33:36because, unlike common myths,

00:33:38they cannot leave their shell

00:33:40on a stroke.

00:33:42The shell of a turtle is an integral part

00:33:44of its body and even if the reptile

00:33:46can hide its head and legs inside

00:33:48to protect itself from predators,

00:33:50its skeleton is fused with the hard shell

00:33:52and like the skeleton

00:33:54of any other animal,

00:33:56it grows with the turtle itself.

00:33:58Koalas only eat

00:34:00eucalyptus leaves, but there are

00:34:02more than 600 different varieties

00:34:04and koalas only eat 30,

00:34:06that is only 5% of what is

00:34:08available on the menu.

00:34:10So it must be a very specific

00:34:12eucalyptus for a difficult koala

00:34:14to accommodate it.

00:34:16These adorable creatures also have

00:34:18something in common with cats.

00:34:20They sleep 18 to 20 hours a day.

00:34:22Polar bears are not white.

00:34:24Their skin is black under their fur

00:34:26to camouflage themselves

00:34:28while they hunt.

00:34:30The black color absorbs the sun

00:34:32better than any other,

00:34:34while the white fur does not stop

00:34:36the light of the sun,

00:34:38the rays cross it.

00:34:40In a way, a polar bear

00:34:42has a transparent fur.

00:34:44There is a myth according to which

00:34:46cats and dogs see the world

00:34:48in black and white.

00:34:50In reality, they simply cannot

00:34:52distinguish certain colors.

00:34:54It could be blue and yellow

00:34:56for what we know,

00:34:58but they can perceive the nuances

00:35:00of other colors better than humans.

00:35:02And cats have a wonderful

00:35:04night vision.

00:35:06They need about seven times

00:35:08less light than humans

00:35:10to see in the dark.

00:35:12We thought giraffes were silent,

00:35:14but we recently discovered that

00:35:16they emitted low-frequency sounds

00:35:18at night to communicate with each other.

00:35:20During the day, they do not say a word

00:35:22but they notice danger in a very unusual way

00:35:24by moving their very developed eyebrows.

00:35:26It is likely that at night

00:35:28it is more difficult for them

00:35:30to distinguish the eyebrows

00:35:32from their congeners,

00:35:34which is why they start talking for good.

00:35:36Still about giraffes,

00:35:38these animals sleep well more than 30 minutes a day,

00:35:40but probably not as much as you.

00:35:42Their sleeping rhythm is quite typical.

00:35:44After watching a herd of giraffes,

00:35:46researchers discovered

00:35:48that they slept at night

00:35:50and took a nap in the afternoon.

00:35:52In total, each giraffe has about

00:35:54five hours of sleep per day.

00:35:56And by the way, a herd of giraffes

00:35:58is actually called a giraffe tower.

00:36:00It is quite logical,

00:36:02knowing that they have such a long neck.

00:36:04Seagulls can drink salty water.

00:36:06They have glands secreting

00:36:08salt near their eyes.

00:36:10These glands quickly purify seawater

00:36:12and the salty residue

00:36:14comes out through their nostrils.

00:36:16Salty morph in a way.

00:36:18Penguins are true romantics.

00:36:20They have only one life partner.

00:36:22The male offers a smooth stone

00:36:24to the female to start a family,

00:36:26a bit like a ring.

00:36:28But as in humans,

00:36:30the penguin female can refuse the gift.

00:36:32Speaking of animal love,

00:36:34foxes are also romantic.

00:36:36Males make good father and husband

00:36:38and they are indebted to their loved ones for life.

00:36:40They take care of the females

00:36:42and even take the chicks out of their fur.

00:36:44They improve the terrier

00:36:46and actively participate in the education

00:36:48of their young.

00:36:50Dolphins can sleep with one eye closed

00:36:52and the other open.

00:36:54Half of the brain rests and dreams

00:36:56while the other half scans the environment

00:36:58in search of signs of danger.

00:37:00The perfect brain to sleep during classes

00:37:02and boring meetings.

00:37:04In addition, dolphins manually control their breathing.

00:37:06If both parts of their brain

00:37:08were sleeping at the same time,

00:37:10they could simply drown.

00:37:12Seagulls are the most adorable

00:37:14of the animal kingdom.

00:37:16In summer, because of the heat,

00:37:18seagulls spend all their time in the water.

00:37:20They swim on their backs

00:37:22and sleep in this position.

00:37:24Babies sleep on their mother's belly

00:37:26and adults hold on to their legs

00:37:28so as not to be separated by the currents.

00:37:30Ostriches do not put their heads

00:37:32in the sand when they feel threatened.

00:37:34In fact, they never put their heads in the sand.

00:37:36This myth spread

00:37:38because of the famous expression

00:37:40« make the ostrich's policy ».

00:37:42In reality,

00:37:44ostriches dig holes in the sand

00:37:46for their eggs

00:37:48because they are birds unable to fly.

00:37:50To ensure that they are uniformly heated,

00:37:52ostriches immerse their heads

00:37:54in order to turn the eggs from time to time.

00:37:56But these animals still have

00:37:58a certain propensity for flight.

00:38:00When they face a threat,

00:38:02they can let themselves fall on the sand

00:38:04and remain perfectly still

00:38:06pretending not to be alive.

00:38:08Although this is a popular belief,

00:38:10ostriches can only breathe while moving

00:38:12because swimming helps them

00:38:14to push water through their gills.

00:38:16Although many types of ostrich

00:38:18are actually designed in this way,

00:38:20many others,

00:38:22such as feeding ostriches

00:38:24that hover at the bottom,

00:38:26do not need to swim

00:38:28to pump rich water into their gills.

00:38:30However, all ostriches are devoid

00:38:32of swimming vessels,

00:38:34so if they stop swimming,

00:38:36they will not be able to breathe.

00:38:38Fortunately, the body of an ostrich

00:38:40cannot be compressed,

00:38:42which is why descents

00:38:44or quick climbs

00:38:46are safe for them.

00:38:48Scientists from Japan

00:38:50listened to audio recordings

00:38:52of cats to prove

00:38:54that they were really ostriches.

00:38:56In these recordings,

00:38:58the owners of the cats

00:39:00called them by their names.

00:39:02Cats' nipples were dilated

00:39:04Cats became close to humans

00:39:06because they were attracted

00:39:08by mice eating our cereals.

00:39:10They lived with people

00:39:12but were never really taught.

00:39:14And yet we continue to feed them.

00:39:16Birds are actually among

00:39:18the last survivors of dinosaurs.

00:39:20They evolved from theropods,

00:39:22dinosaurs that ran on two legs.

00:39:24So technically, the T-Rex

00:39:26is a distant cousin of the chicken,

00:39:28ostrich and even hummingbird.

00:39:30In reality, pink flames are white,

00:39:32thanks to beta-carotene,

00:39:34a pigment found in algae

00:39:36and the shrimp they feed on.

00:39:38You can also change the color of your skin.

00:39:40If you eat a lot of carrots,

00:39:42it will become slightly orange.

00:39:44This will occur because of the strong beta-carotene

00:39:46content of the vegetable.

00:39:48Sailors from all over the world

00:39:50have spoken of giant calamari

00:39:52they encountered during their journey.

00:39:54For many years,

00:39:56scientists have considered

00:39:58that long-tentacled monsters

00:40:00The first picture of a giant calamari

00:40:02has been realized.

00:40:04They really exist.

00:40:06Scientists have measured an animal

00:40:08of nearly 13 meters.

00:40:10Mosquitoes really sting some people

00:40:12more than others.

00:40:14The most attractive humans for them

00:40:16are those who have blood type O.

00:40:18In addition, these insects have a very good sight.

00:40:20They are attracted by green, black and red colors.

00:40:22So check the color of your clothes

00:40:24before going camping.

00:40:26You can put a shark in a trance for 15 minutes.

00:40:28To do this, you have to caress the animal's nose

00:40:30with your hand.

00:40:32This kind of hypnosis is called tonic immobility.

00:40:34It occurs thanks to the receptors

00:40:36present in the shark's nose.

00:40:38When you caress them, the receptors send

00:40:40many signals and the shark's brain

00:40:42is unable to treat them all.

00:40:44That's how you're supposed to get close

00:40:46enough of a shark to rub his nose.

00:40:48Elephants are not afraid of mice

00:40:50in themselves, but these massive animals

00:40:52have a bad sight

00:40:54and they move quite slowly.

00:40:56Sometimes they can be scared by a bird

00:40:58or a small creature, like a mouse,

00:41:00which passes in front of them.

00:41:02It's just a surprise.

00:41:04The chameleon can change color,

00:41:06but it doesn't do it to camouflage itself.

00:41:08The change of color helps the animal

00:41:10to regulate its temperature

00:41:12and communicate with its peers.

00:41:14When most dogs bark,

00:41:16their tongues hang from their mouths.

00:41:18That's why a lot of people think

00:41:20that's how they sweat.

00:41:22In fact, the glands on which the dogs

00:41:24sweat are the glands of their paws.

00:41:26In addition, there are other glands

00:41:28on all their bodies.

00:41:30Dogs help to evaporate the humidity

00:41:32of their nasal voice, their tongue

00:41:34and the wall of their lungs.

00:41:36It also helps them to cool down.

00:41:38You're probably watching out

00:41:40to leave the geese alone,

00:41:42but don't be so sure they'll do the same to you.

00:41:44Bees respect your limits

00:41:46and if you don't bother them,

00:41:48they won't hurt you.

00:41:50But geese, for their part,

00:41:52are very complicated,

00:41:54even if you're just passing by their nest.

00:41:56Sea leopards are cute, aren't they?

00:41:58It's impossible for a creature

00:42:00with such pretty eyes to hurt you.

00:42:02You wouldn't expect it,

00:42:04especially when you see

00:42:06all these seals on TV

00:42:08who like to play with humans.

00:42:10But sea leopards are super predators.

00:42:12You shouldn't trust them too much.

00:42:14After all, their name comes from their fur

00:42:16that looks like that of big felines.

00:42:18They are located at the top

00:42:20of the food chain.

00:42:22Very few animals attack them.

00:42:24It's not so common,

00:42:26but sea leopards have already

00:42:28attacked humans.

00:42:30In general, they are more aggressive

00:42:32than other seals.

00:42:34They are not sociable animals.

00:42:36In general, they prefer to be alone.

00:42:38Their beaks are always up,

00:42:40so that they show a wide smile.

00:42:42Since they are solitary animals,

00:42:44they have more difficulty

00:42:46finding a partner.

00:42:48They attract them

00:42:50by using their voices

00:42:52and sometimes by singing under the water.

00:42:54It's difficult to distinguish

00:42:56a sea leopard from a stray dog.

00:42:58But be careful!

00:43:00Sea leopards are closer to wolves

00:43:02than to dogs.

00:43:04They are Australia's biggest terrestrial predators

00:43:06and they are also super predators.

00:43:08They attack their prey in packs.

00:43:10When there are several,

00:43:12they can attack even bigger animals

00:43:14like kangaroos.

00:43:16But if you meet them in packs,

00:43:18it's better to avoid them.

00:43:20Everyone loves pandas.

00:43:22With their adorable beaks

00:43:24and their innocent look,

00:43:26they have become the symbol of kindness

00:43:28and serenity.

00:43:30They are also very lazy

00:43:32and they spend most of their time

00:43:34resting and eating bamboo.

00:43:36They certainly look peaceful,

00:43:38but it's better not to bother them.

00:43:40If by accident you cross the territory

00:43:42of a panda or it considers you

00:43:44as a threat,

00:43:46don't be afraid.

00:43:48They are very powerful

00:43:50and are usually stronger

00:43:52than humans.

00:43:54They rarely attack humans,

00:43:56but it's better to leave them alone

00:43:58themselves.

00:44:00The nyctiseb.

00:44:02This animal is so slow

00:44:04that even in case of danger,

00:44:06it moves.

00:44:08Don't be fooled by its big eyes

00:44:10and small nose.

00:44:12It can cause you a lot of problems.

00:44:14Researchers say that the lorislan

00:44:16imitates the cobra.

00:44:18It is one of the rare venomous mammals

00:44:20of the animal world.

00:44:22It does not secrete venom by its mouth

00:44:24like most other animals,

00:44:26but by the sudoral glands located

00:44:28on its arms.

00:44:30So it's not a nice little bear,

00:44:32but rather a real monster.

00:44:34Same for the koala.

00:44:36It looks so calm,

00:44:38but it attacks you without problem

00:44:40because it feels threatened.

00:44:42It's not a dangerous animal.

00:44:44It spends most of its time

00:44:46on its eucalyptus trees.

00:44:48It sleeps 22 hours a day.

00:44:50If you ever meet it in nature,

00:44:52it will probably just climb higher

00:44:54on its tree to avoid you.

00:44:56But if it feels threatened,

00:44:58it can use its claws and teeth

00:45:00to defend itself.

00:45:02The cygne are delicate and graceful,

00:45:04but also romantic.

00:45:06They are sometimes associated

00:45:08with animals that are vulnerable.

00:45:10But in this case,

00:45:12we could also talk about cow love

00:45:14because the cygne can also be

00:45:16really dangerous.

00:45:18If they feel in danger,

00:45:20they do everything they can

00:45:22to protect themselves

00:45:24and, above all,

00:45:26protect their young.

00:45:28They will start by peeing a little

00:45:30like cats do,

00:45:32and then they will start

00:45:34to flap their wings.

00:45:36The cygne is like a mixture

00:45:38of several animals.

00:45:40Look at its palmed paws and beak.

00:45:42It looks like a duck, doesn't it?

00:45:44But it has the fur of a lout

00:45:46and the tail of a beaver.

00:45:48It is so graceful when it swims

00:45:50underwater with its palmed paws,

00:45:52but it is not as elegant

00:45:54when it moves on land.

00:45:56It then takes out its claws

00:45:58so that it can walk more easily.

00:46:00The males secrete venom.

00:46:02They have ergot on the heels

00:46:04to defend themselves.

00:46:06Androbat frogs.

00:46:08The toads look much more intimidating

00:46:10than this pretty little frog.

00:46:14But the toad is just ugly

00:46:16and it won't hurt you

00:46:18unlike the latter.

00:46:20There are more than 100

00:46:22venomous frog species

00:46:24and they each have a different level of toxicity.

00:46:26The golden frog,

00:46:28known as the terrible philobat,

00:46:30is the most dangerous and can kill

00:46:32anyone who touches it.

00:46:34The hedgehog

00:46:36is a very appreciated animal.

00:46:38It is a cute and innocent little creature

00:46:40that gets in trouble when needed.

00:46:42But it is still a stingy animal

00:46:44and it won't hesitate

00:46:46to use its stings to defend itself

00:46:48from danger.

00:46:50If the stings pierce your skin,

00:46:52it can hurt a lot.

00:46:54The ant.

00:46:56With its soft eyes,

00:46:58the ant looks harmless.

00:47:00But it has claws.

00:47:02It generally uses them

00:47:04to find food

00:47:06but of course it uses them

00:47:08if it feels in danger.

00:47:10Did you know that their tongue

00:47:12is covered with stings?

00:47:14Yes, it is their main tool

00:47:16for food harvesting

00:47:18and this tongue can measure up to 60 cm.

00:47:20It is long and thin

00:47:22to allow them to look for termites

00:47:24and ants

00:47:26in narrow corners.

00:47:28The owls

00:47:30are not as cute

00:47:32but they have this shy and intelligent look.

00:47:34In addition, they don't really

00:47:36care about humans.

00:47:38Except when this one approaches

00:47:40and touches its nest.

00:47:42There, they get angry.

00:47:44They have long claws to hold

00:47:46so it's better not to bother them.

00:47:48In addition, they can turn their heads

00:47:50at 270 degrees

00:47:52so even if you think to surprise them from behind,

00:47:54they will see you.

00:47:56Kangaroos

00:47:58are not the kind to look for trouble

00:48:00but if you look for them,

00:48:02they will not hesitate to show you

00:48:04who is the boss.

00:48:06They can measure up to a human

00:48:08as if it were another kangaroo.

00:48:10They have very powerful arms

00:48:12and can hit you with their legs.

00:48:14But it's even worse

00:48:16when they hit you with their hind legs.

00:48:18Deer

00:48:20seem to come straight out

00:48:22of a fairy tale

00:48:24Males do not hesitate

00:48:26to use their voices

00:48:28if they feel threatened.

00:48:30They also have the habit

00:48:32of entering individuals' gardens

00:48:34and eating what they find there.

00:48:36They can also be dangerous

00:48:38for domestic animals,

00:48:40especially dogs.

00:48:42Foxes can't hurt us

00:48:44with this love bubble, can they?

00:48:46However, they can be carriers of rage

00:48:48so it's better not to get too close to them.

00:48:50In general, they avoid humans

00:48:52because they can be aggressive

00:48:54towards humans and small animals.

00:48:56They are quite unpredictable

00:48:58so be careful.

00:49:00Mice

00:49:02seem so nice and cute

00:49:04that we think they can do nothing

00:49:06worse than digging in our garbage.

00:49:08But that's not quite the case.

00:49:10These little guys are not afraid

00:49:12to come out of their hole

00:49:14if they feel in danger.

00:49:16Even if you just went to see

00:49:18who was making all this noise

00:49:20they have sharp claws

00:49:22that are better avoided.

00:49:24Tarsiers are one of the smallest primates

00:49:26in the world

00:49:28and they are also the cutest.

00:49:30When you see them,

00:49:32you just want to pet them.

00:49:34But it's better to abstain.

00:49:36They are not particularly dangerous

00:49:38but they are not fond of humans

00:49:40touching them

00:49:42so they can react quite unpredictably.

00:49:44It's better to admire them from afar.

00:49:46A year for a human

00:49:48You may have heard that dogs

00:49:50age 7 times faster than us

00:49:52but it's not that simple.

00:49:54A dog that has been living for a year

00:49:56is already 31 years old.

00:49:58It will probably have

00:50:00its own little puppies

00:50:02running everywhere.

00:50:04But that's where it gets complicated.

00:50:062 years for a human

00:50:08doesn't necessarily mean

00:50:10that your dog is 62 years old.

00:50:12Your companion should be around

00:50:144 years old in our calendar

00:50:16A 4-year-old dog will be around

00:50:1850 years old

00:50:20but a 7-year-old dog will be 62

00:50:22and an 8-year-old dog will only be 64.

00:50:24So they age faster at first

00:50:26but slower

00:50:28as time goes by.

00:50:30The next time you celebrate

00:50:32your best friend's birthday

00:50:34make sure to put a lot of candles on the cake

00:50:36and buy even more gifts

00:50:38than you would normally do.

00:50:40Another very common idea

00:50:42is that dogs are daltonian.

00:50:44But they don't see the colors

00:50:46exactly like us.

00:50:48They can't tell the red from the green.

00:50:50Everything looks like a mix

00:50:52of grey, brown, blue

00:50:54and even yellow.

00:50:56That's because they're missing

00:50:58one of the three photoreceptors

00:51:00necessary to fully perceive the colors.

00:51:02You can't teach

00:51:04a new trick to an old dog.

00:51:06Wrong! Because of their advanced age

00:51:08they may need more perseverance

00:51:10from you, but that's not impossible.

00:51:12The key here

00:51:14is to be as positive as possible.

00:51:16If you see that he doesn't feel well

00:51:18for the moment, it doesn't matter.

00:51:20Let him rest and after a while

00:51:22you can resume the training session.

00:51:24Rewards must always

00:51:26play an important role in this test.

00:51:28Once Max has managed to talk

00:51:30give him his favorite treat.

00:51:32Then he will obey on command

00:51:34every time you ask him.

00:51:36This dog has shoes.

00:51:38They may seem useless, but today

00:51:40it's 32°C outside.

00:51:42Imagine that you have to walk barefoot

00:51:44on asphalt in this heat.

00:51:46You'll feel like you're walking on lava.

00:51:48It's the same for your dog.

00:51:50Some dogs are better equipped

00:51:52to face different weather conditions.

00:51:54But dog shoes can prevent

00:51:56your little companion from getting hurt.

00:51:58It's the same thing in winter.

00:52:00When it's freezing cold

00:52:02you won't walk around without a jacket.

00:52:04So make sure your friend is also

00:52:06warm. Dogs with a lot of fur

00:52:08don't need to get their hair cut

00:52:10to feel lighter.

00:52:12They have what we call a undercoat.

00:52:14In winter it thickens,

00:52:16which gives your companion

00:52:18an additional layer of protection

00:52:20against the cold.

00:52:22Then in spring, your dog

00:52:24loses part of his fur.

00:52:26It's this same undercoat

00:52:28that will keep your dog

00:52:30comfortable during hot days.

00:52:32When you shave a dog's fur

00:52:34the new layer that arrives

00:52:36You can also always find

00:52:38different alternatives to keep him cool.

00:52:40Leave him in the shade when he's outside

00:52:42and always bring a bottle of fresh water

00:52:44with you so that your friend

00:52:46is always cool.

00:52:48At home you can put wet towels

00:52:50so that he can lie down on them.

00:52:52If you have a garden, you can also

00:52:54start watering and let Max run freely.

00:52:56He'll do some exercise and have a lot of fun.

00:52:58Not all dogs are great swimmers,

00:53:00but all dogs like to swim.

00:53:02If your dog doesn't know how to swim

00:53:04maybe it's because he has a big chest

00:53:06and a big head.

00:53:08In fact, he may not even be able

00:53:10to stay afloat.

00:53:12In this case, buy him a swimming vest

00:53:14specially designed for dogs.

00:53:16Some people might say

00:53:18that a slightly open window

00:53:20is enough to leave a dog in a car.

00:53:22That's not true, because if he spends

00:53:24only a few minutes in a very hot or cold car

00:53:26it can have serious consequences

00:53:28on the health of your best friend.

00:53:30Some countries even allow you

00:53:32to take a dog out of a car

00:53:34if you see him in it

00:53:36to let him breathe.

00:53:38If your dog can't stand factors

00:53:40maybe it's because he's trying

00:53:42to protect you.

00:53:44He barks because he's trying

00:53:46to warn you, the boss,

00:53:48that the bad factor is coming.

00:53:50You can remedy this

00:53:52by introducing them to each other.

00:53:54This way your dog will recognize him

00:53:56as a friend and not as a villain.

00:53:58Unlike you, your dog doesn't bark

00:54:00to show his anxiety.

00:54:02If he doesn't like cats and there's one nearby

00:54:04he might start barking.

00:54:06Or maybe there's a new person in the house

00:54:08and Max doesn't feel comfortable in his presence.

00:54:10Or you take your dog

00:54:12to play with another one, but they don't get along.

00:54:14Max doesn't stop barking

00:54:16because he's angry.

00:54:18Barking is also a way to show you

00:54:20that he's out of patience.

00:54:22Maybe it's time for you two to go.

00:54:24Dogs eat grass

00:54:26when they're sick, but that's not always the case.

00:54:28If you surprise your dog

00:54:30by eating grass when you've been

00:54:32talking to a friend for too long,

00:54:34it probably means he's just bored.

00:54:36He does it to rebel

00:54:38or simply because it's fun.

00:54:40It won't be a problem if the grass isn't treated.

00:54:42In any case,

00:54:44make sure he doesn't eat too much

00:54:46or go to the vet.

00:54:48Even a little bit of chocolate

00:54:50is toxic for your dog

00:54:52and must be hidden at all times.

00:54:54This includes cocoa powder

00:54:56and chocolate.

00:54:58It also applies to cats.

00:55:00If you suspect your dog

00:55:02has eaten a large amount of chocolate,

00:55:04take him to the vet immediately.

00:55:06Well-behaved dogs

00:55:08will do what they're supposed to

00:55:10and obey orders.

00:55:12But don't think a dog will never bite.

00:55:14It can react to emotion.

00:55:16Imagine your dog is scared.

00:55:18You've put him in an uncomfortable situation

00:55:20with a lot of new faces.

00:55:22It's been going on for a while

00:55:24and Max is no longer able to control his emotions.

00:55:26At that moment,

00:55:28a new person tries to reach him

00:55:30to caress him and punish him.

00:55:32Nothing bad, but it was unexpected.

00:55:34Maybe he felt he needed to be on the defensive.

00:55:36Thinking he's protecting you

00:55:38is another reason

00:55:40why a dog can bite

00:55:42or if he feels too intimidated

00:55:44by the person in question.

00:55:46You have two dogs

00:55:48and you're about to enter your house.

00:55:50One of them is waiting for you in his bed.

00:55:52He doesn't feel anything

00:55:54and doesn't wag his tail.

00:55:56The other one comes running to the door.

00:55:58He whines, jumps and wags his body

00:56:00while running around you.

00:56:02That doesn't mean he loves you more.

00:56:04It simply means

00:56:06he's not well-behaved yet.

00:56:08Wagging his tail doesn't always mean

00:56:10your dog is excited.

00:56:12You can observe a dog's tail

00:56:14to understand what it feels like.

00:56:16If he keeps his tail up

00:56:18but doesn't move it,

00:56:20it means his feelings have changed.

00:56:22He's alert but happy.

00:56:24He always tries to show he's the boss

00:56:26but he also feels excited.

00:56:28When his tail is between his legs,

00:56:30your dog is scared.

00:56:32If there's an alpha male in the house,

00:56:34it can mean your companion

00:56:36accepts his leadership.

00:56:38A tail outwards

00:56:40means the dog is absorbing

00:56:42new information,

00:56:44feeling the room.

00:56:46You can also observe

00:56:48that your dog is neutral.

00:56:50If a dog's tail moves quickly,

00:56:52it means he's excited.

00:56:54The more he wags his tail,

00:56:56the more excited he is.

00:56:58A slow wagging

00:57:00is a sign of insecurity.

00:57:02It could be because

00:57:04there's another dog

00:57:06or someone else around.

00:57:08Now imagine your dog

00:57:10wagging his whole body.

00:57:12You can even see his pelvis

00:57:14moving.

00:57:16It means he's friendly.

00:57:18It can happen when you're in the elevator

00:57:20and he sees his best friend.

00:57:24The worst of all wagging

00:57:26is extremely fast

00:57:28and vertical wagging.

00:57:30When he does this,

00:57:32your dog can be aggressive with others.

00:57:34He may feel territorial

00:57:36towards you.

00:57:38It's better to move away.

00:57:40If your dog's tail moves to the right,

00:57:42it means he's relaxed.

00:57:44If his tail moves to the left,

00:57:46it means he's stressed.

00:57:50Psst! Run!

00:57:52Really! It's not safe outside.

00:57:54There's a tiger with a saber

00:57:56roaming around. You should be careful.

00:57:58What are you doing? Don't look!

00:58:00OK, just take a look.

00:58:02How is it possible, you ask?

00:58:04It's because you're in virtual reality,

00:58:06of course. These big felines

00:58:08with nice but dangerous looks

00:58:10lived during the last ice age.

00:58:12What if they showed up

00:58:14at your doorstep?

00:58:16Knock, knock!

00:58:18A saber-toothed cat is waiting for you

00:58:20to buy him some cookies.

00:58:22The Coelacanth,

00:58:24this fish with an imposing look,

00:58:26is from a line that has existed

00:58:28for more than 300 million years.

00:58:30We thought it didn't exist

00:58:32until 1938,

00:58:34when a living Coelacanth

00:58:36was found. Since then,

00:58:38it's been living in the waters

00:58:40of Sulawesi, Indonesia.

00:58:42Dude, I don't want to go

00:58:44swimming and meet one of these guys

00:58:46face to face. Their jaws

00:58:48have an intracranial joint,

00:58:50which means their mouths open a lot.

00:58:52It's so they can eat

00:58:54big fish, like me.

00:58:56It's not good. They're huge too.

00:58:58Imagine a fish that's as long

00:59:00as you and weighs as much

00:59:02as an ordinary human.

00:59:04We thought the Takahē,

00:59:06an incapable bird of prey,

00:59:08had disappeared in 1898.

00:59:10They're very beautiful,

00:59:12small and multicolored.

00:59:14Usually not taller than your knee.

00:59:16But imagine that.

00:59:18You're hiking in the Murchison Mountains,

00:59:20you look around you

00:59:22and you see the bird you thought was gone.

00:59:24But they're there, happier than ever,

00:59:26surviving

00:59:28and refreshing.

00:59:30An entire Takahē colony

00:59:32was found only 50 years after

00:59:34they were declared extinct.

00:59:37A singing dog?

00:59:39Have you ever heard of one?

00:59:41Railay sometimes sings

00:59:43when he's bored or hungry,

00:59:45but these are real artists,

00:59:47the New Guinea singing dogs.

00:59:49They were recently discovered

00:59:51in the wild for the first time

00:59:53in 50 years.

00:59:55Yet they were never completely extinct at first.

00:59:57The New Guineans made sure

00:59:59they were safe next to them.

01:00:01But in the wild,

01:00:03it's very rare and hard to see.

01:00:05Look, here's one!

01:00:07The New Guinea singing dogs

01:00:09are called that because of their famous high voice.

01:00:11They sometimes sing together.

01:00:13A kind of dog choir

01:00:15where they all scream together.

01:00:17I bet they sing better than me in the shower.

01:00:21Not far from here,

01:00:23we have bats.

01:00:25But these are a bit different.

01:00:27You see, their ears are huge.

01:00:29I guess that's why they're called

01:00:31the big-eared bats of New Guinea.

01:00:33Smart!

01:00:35The species was discovered

01:00:37when one of them was accidentally caught

01:00:39in a bat trap.

01:00:41Until then,

01:00:43I guess they were playing hide-and-seek with us

01:00:45because until 1890,

01:00:47they were thought to have disappeared.

01:00:49They are still not out of the danger zone

01:00:51because of habitat loss.

01:00:53Imagine that you discover a fossil

01:00:55of a species that you thought was extinct

01:00:57for a long time,

01:00:59and that two years later,

01:01:01you discover a fossil of this species.

01:01:03That's exactly what happened

01:01:05in 1977 with the New Guinea

01:01:07singing dogs.

01:01:09It has a brownish colour

01:01:11with darker spots on its skin.

01:01:13Apart from that,

01:01:15it's just a small bat with bubbly eyes.

01:01:17The group of living bats

01:01:19was found near the place

01:01:21where the fossil was found on New Guinea.

01:01:23There are not many left,

01:01:25about 500 in fact,

01:01:27and at the moment,

01:01:29they are protected by the International Union

01:01:31for Conservation of Nature.

01:01:33Are you a fan of turtles?

01:01:35You'll know when you take a look

01:01:37at this enormous beauty.

01:01:39It's called the Galapagos turtle

01:01:41from Fernandina Island.

01:01:43It hadn't been seen since 1906,

01:01:45but on 17 February 2019,

01:01:47we were finally able to see

01:01:49one of these magnificent creatures.

01:01:51It's probably outside

01:01:53with some of its companions

01:01:55at the moment,

01:01:57but it doesn't let itself be seen either.

01:01:59We only know that they exist

01:02:01because there are some traces and smells.

01:02:05Here's another frog,

01:02:07the horned marsupial frog.

01:02:09It's found in Ecuador,

01:02:11in the Choco Forest,

01:02:13to be more precise.

01:02:15They are called that

01:02:17because of their distinct horns

01:02:19just above their eyes.

01:02:21Do you know the pocket

01:02:23that kangaroos use

01:02:25to hide?

01:02:27They also have one,

01:02:29except that it's on its back

01:02:31and acts like a kind of backpack.

01:02:33They develop their embryos

01:02:35here, and when they're ready to go out,

01:02:37they hatch like complete babies,

01:02:39unlike ordinary frogs

01:02:41that start out as tadpoles.

01:02:43Here's another toad,

01:02:45the starry night toad

01:02:47or harlequin toad.

01:02:49They're black and covered

01:02:51in a multitude of white spots.

01:02:53Imagine them

01:02:55as bodyguards,

01:02:57or bodyguards of water,

01:02:59to be exact.

01:03:01Oh, that's a very big toad on your screen!

01:03:03Well, for the Arhuaco people,

01:03:05that's exactly what they are,

01:03:07bodyguards of water.

01:03:09They also have their own name,

01:03:11Guna. It looks like a cheese.

01:03:13When scientists found them,

01:03:15they met 30 of these

01:03:17little creatures,

01:03:19while they only expected one at the start.

01:03:21What a nice surprise!

01:03:25Here's a tiger for you,

01:03:27although it doesn't quite look like

01:03:29a classic tiger.

01:03:31It's a Tasmanian tiger

01:03:33that seems to have disappeared since 1936.

01:03:35Out of nowhere,

01:03:37we began to see it in the wild

01:03:39just 5 years ago,

01:03:41in 2016.

01:03:43It kind of looks like a dog

01:03:45more than a tiger, or a fox, maybe.

01:03:47Just look at its muzzle.

01:03:49Maybe even a mix of the two.

01:03:51Then a few others began to appear, too.

01:03:53And if you think you see one

01:03:55right in front of you,

01:03:57but you're not sure,

01:03:59check if it has stripes on its back.

01:04:01They do exist,

01:04:03but are still considered extinct

01:04:05by the UICN.

01:04:07OK,

01:04:09imagine a horse that seems

01:04:11straight out of a movie.

01:04:13Very small, a magnificent fur,

01:04:15very well raised.

01:04:17It's not a pony,

01:04:19it's a Caspian horse.

01:04:21They have an interesting story.

01:04:23They were discovered by

01:04:25Louise Leylin,

01:04:27who married an aristocrat in 1957.

01:04:29Having moved to Tehran,

01:04:31in Iran,

01:04:33she didn't like the behavior

01:04:35of the horses there,

01:04:37so she took things into her own hands.

01:04:39She took a few people with her

01:04:41and they went to the Caspian Sea mountain.

01:04:43And there they found

01:04:45a horse.

01:04:47That's how the story began.

01:04:49Then,

01:04:51an opossum

01:04:53was found in an unexpected place.

01:04:55Guess where?

01:04:57You have three options.

01:04:59Hiding in a ski resort,

01:05:01in an Australian outback,

01:05:03or in the bathroom of an apartment.

01:05:05Which one do you choose?

01:05:07You have three seconds.

01:05:11The right answer is

01:05:13the ski resort.

01:05:15Yes, this opossum

01:05:17was called the Nile Mountain Opossum

01:05:19and it's from Australia.

01:05:21Until now,

01:05:23there are three different populations

01:05:25of this little opossum,

01:05:27but it was thought to have been extinct

01:05:29until 1966.

01:05:31There are less than 100 of them

01:05:33and the UCN considers them

01:05:35to be in critical danger of extinction.

01:05:37Also from Australia,

01:05:39the nocturnal parakeet.

01:05:41An absolute pleasure for birdwatchers.

01:05:43Very beautiful and mysterious,

01:05:45these little guys live

01:05:47in very remote areas.

01:05:49You can probably count on your fingers

01:05:51the number of times these birds have been seen

01:05:53since they were found in 1979.

01:05:55It means

01:05:57how rare they are.

01:06:01Have you ever seen a pygmy parakeet?

01:06:03Me neither.

01:06:05It was only in 2008 that three of them

01:06:07were captured.

01:06:09Parakeets don't want to lose

01:06:11their movement again,

01:06:13so they were given very small necklaces.

01:06:15This way, they can live their lives

01:06:17as happily as ever

01:06:19and we know they are safe.

01:06:23The last one I want to talk to you about

01:06:25is the tree lobster.

01:06:27But as its name could make you think wrong,

01:06:29they are not really lobsters.

01:06:31They are just big black animals

01:06:33with huge legs.

01:06:35The story of their extinction is sad.

01:06:37In 2020, a cargo ship got stuck

01:06:39on Lord Howe Island

01:06:41and there were rats on board.

01:06:43These rats fled the ship

01:06:45and ran straight to the mainland.

01:06:47Even though tree lobsters

01:06:49are bigger than most insects,

01:06:51they are still relatively small

01:06:53compared to rats.

01:06:55The poor ones had no chance.

01:06:57However, in 2004,

01:06:59life resumed its course

01:07:01for these distinctive creatures.

01:07:03Two Australian scientists

01:07:05found 24 of them.

01:07:07All of them lived under one bush.

01:07:09Hey, if there is enough space

01:07:11for everyone,

01:07:13it's not small, it's sweet.

01:07:15Conclusion?

01:07:17It's better to be different than extinct,

01:07:19isn't it?

01:07:21Did you know that animals

01:07:23saw the world differently from us?

01:07:25Let's take this as an example.

01:07:27Pigeons have a better view than humans.

01:07:29It's crazy, isn't it?

01:07:31So let's try to see the world

01:07:33like a snake.

01:07:35Their way of seeing the world

01:07:37is totally different from ours.

01:07:39They have special infrared-sensitive

01:07:41receptors in their muzzle.

01:07:43This allows them to perceive

01:07:45the heat emitted by the mammals

01:07:47when they are hot.

01:07:49Now let's move on to cows.

01:07:51These big guys can't see colors

01:07:53as well as humans.

01:07:55They are unable to perceive

01:07:57the color red

01:07:59because they don't have

01:08:01their vision is almost panoramic

01:08:03and the only area they can't see

01:08:05directly is the back of their head.

01:08:07So if you ever sneak behind a cow,

01:08:09make sure you get noticed.

01:08:11Horses have a blind spot

01:08:13right in front of their face

01:08:15because of the position of their eyes.

01:08:17This means they can't see things

01:08:19directly in front of them.

01:08:21In addition, they don't perceive

01:08:23as many colors as we do.

01:08:25Just like cows, their world is mainly

01:08:27composed of green, yellow and blue.

01:08:29Their ultraviolet receptors

01:08:31are more rounded than ours.

01:08:33This gives them a 360-degree vision.

01:08:35As far as colors are concerned,

01:08:37they are able to see the same as we do.

01:08:39But since light behaves differently

01:08:41underwater, they have trouble

01:08:43distinguishing red and its shades.

01:08:45Deep-sea fish can easily see

01:08:47in the dark, which is extremely useful.

01:08:49Sharks, on the other hand,

01:08:51can't distinguish colors at all,

01:08:53but they see much more clearly

01:08:55underwater than we do.

01:08:57Horses are quite unique in seeing the world.

01:08:59Unlike humans, they can distinguish

01:09:01the ultraviolet light.

01:09:03This helps them to differentiate

01:09:05males and females from their own species

01:09:07as well as to better locate themselves

01:09:09in their environment.

01:09:11In addition, they are very good

01:09:13at focusing. So falcons and eagles

01:09:15can focus on a small mouse

01:09:17in a field up to a distance

01:09:19of more than 1 km.

01:09:21A pigeon can perceive all kinds

01:09:23of small details. So if you ever need

01:09:25to go to the toilet,

01:09:27you can go to the pigeon.

01:09:29In fact, they have a field of vision

01:09:31of 340 degrees and, in general,

01:09:33their sight is considered

01:09:35twice as sharp as that of humans.

01:09:37There you go, I'm jealous of a pigeon.

01:09:39Insects also have quite strange

01:09:41perception patterns.

01:09:43Flies, for example, have thousands

01:09:45of small ocular receptors

01:09:47that work together to give them

01:09:49a global view of what's going on

01:09:51around them. And guess what?

01:09:53Bees have their own problem.

01:09:55These little creatures are unable

01:09:57to recognize the color red.

01:09:59For them, it just looks like dark blue.

01:10:01It's crazy, isn't it?

01:10:03Let's move on to rats. These little guys

01:10:05can't see red either, but that's not

01:10:07the strangest part. Each of their eyes

01:10:09moves independently, so that they

01:10:11see double all the time. It's surprising

01:10:13that they don't bump into walls more often,

01:10:15don't they? Cats don't perceive

01:10:17shades of red or green, but they

01:10:19distinguish brown, yellow and blue

01:10:21from each other. In addition, they have a wide-angle

01:10:23vision, so that they have a better

01:10:25peripheral vision than ours.

01:10:27And there's more. When it's completely

01:10:29dark outside, cats turn into

01:10:31ninjas and see up to six times better than us.

01:10:33Their pupils adapt to any

01:10:35light as if by magic.

01:10:37Now, let's talk a little about dogs.

01:10:39Our furry companions can't see

01:10:41red or orange, but they excel

01:10:43in blue and purple. In addition,

01:10:45they can differentiate up to 40 shades

01:10:47of gray. Well, it's not 50,

01:10:49but it's still impressive. On their side,

01:10:51frogs are really difficult in

01:10:53terms of food. They don't get bored

01:10:55with immobile prey. They could be surrounded

01:10:57by a buffet of delicious insects.

01:10:59But if all that doesn't move, frogs

01:11:01won't even care. And they're not

01:11:03the finest observers either.

01:11:05If something seems uninteresting to them,

01:11:07like a shadow, for example, they won't

01:11:09even look. Chameleons

01:11:11have eyes that can move

01:11:13independently of each other. So they can

01:11:15see everything around them without even

01:11:17looking. They are even able to see

01:11:19two images at the same time, like watching

01:11:21two different movies side by side. Pretty

01:11:23badass, right? And you, what would you do

01:11:25if you suddenly had a 360-degree

01:11:27vision like a chameleon? Share your

01:11:29opinion in the comments.

01:11:31You wake up with a heavy head.

01:11:33Hmm. One, where is your comfortable bed?

01:11:35And two, why are you sleeping

01:11:37on the floor on a wet and dirty floor

01:11:39in the middle of nowhere?

01:11:41Wait, what are all these things around you?

01:11:43You are... in the jungle?

01:11:45There is a big backpack nearby

01:11:47with basic necessities

01:11:49like water, biscuits,

01:11:51candy and a jacket.

01:11:53All this is yours, that's for sure.

01:11:55But still, what's going on?

01:11:57How the hell did you get here?

01:11:59Wait, a jacket?

01:12:01It's incredibly hot.

01:12:03You certainly won't need that.

01:12:05Seriously, what is this place?

01:12:07Plants with giant leaves?

01:12:09Big trees from the tropical forest?

01:12:11Hmm, it looks a bit like

01:12:13Jurassic Park.

01:12:15You jump out of fear,

01:12:17look around you and

01:12:19run under one of these big plants.

01:12:21Okay, it's not a good choice

01:12:23and certainly not the best time to

01:12:25remember that you suck at hide-and-seek.

01:12:27There is a huge weird animal

01:12:29coming out of the bushes

01:12:31and looking at you. A dinosaur!

01:12:33You scream, you shiver,

01:12:35you cover your eyes.

01:12:37That's not exactly how you expected

01:12:39to spend your morning.

01:12:41The dinosaurs don't bark.

01:12:43You open your eyes.

01:12:45This thing certainly attacked you,

01:12:47but now it jumps everywhere,

01:12:49moves its long tail, barks and speaks.

01:12:51And it looks so familiar.

01:12:53Is it a dog?

01:12:55You almost scream in relief.

01:12:57This thing is weird. A dog...

01:12:59Ozzor. What else could it be?

01:13:01Big, grey and hairy,

01:13:03but incredibly similar

01:13:05to a T-Rex.

01:13:07Its front paws are actually short arms

01:13:09and its long muzzle with pointed teeth

01:13:11spins around you.

01:13:13While the Ozzor dog covers you with

01:13:15dinosaur droppings, another hairy thing

01:13:17comes out of the bushes.

01:13:19White and hairy, with short front paws,

01:13:21a long dark grey tail

01:13:23and ridiculously large ears.

01:13:25It's a Lapinozor.

01:13:27The two animals start to chase each other

01:13:29and make squabbles.

01:13:31Uh, is it for real?

01:13:33The Ozzor dog gets bored and runs to you.

01:13:35It starts rubbing its head on your arm.

01:13:37You caress it while wondering

01:13:39what you're going to do next.

01:13:41What happens if this thing gets bored or...

01:13:43hungry?

01:13:45I'll call it Max. You take a stick

01:13:47and run as far as you can.

01:13:49At least it's over.

01:13:51The Ozzor dog is gone

01:13:53and the questions start to invade your brain.

01:13:55What is this thing doing in the jungle?

01:13:57What else lives here?

01:13:59Will they all be as nice?

01:14:01Or not?

01:14:03You don't need long to know.

01:14:05A terrible thing invades your ears.

01:14:07You turn slowly this time.

01:14:09Another surprise.

01:14:11A few meters away,

01:14:13another huge beast looks at you.

01:14:15Its eyes are the scariest part,

01:14:17wide open and directed

01:14:19directly at you.

01:14:21You hold your breath.

01:14:23Everything could end in an instant.

01:14:25But after a while, you sigh

01:14:27of relief. It's just a zebra.

01:14:29Well,

01:14:31a zebra-ozzor.

01:14:33It has black and white stripes on a muscular body

01:14:35and wow!

01:14:37Its head is super long.

01:14:39Its tail looks serious

01:14:41and its back is covered with bone plates.

01:14:43The zebra-ozzor takes a step forward.

01:14:45Zebras only eat grass

01:14:47and stuff like that, don't they?

01:14:49I hope this thing does too.

01:14:51Let's see. Three options.

01:14:53Run, lie down

01:14:55or caress the giant zebra-ozzor.

01:14:57Wham! A much more hairy beast

01:14:59jumps out of the bushes and the race is on.

01:15:01Was it a bite?

01:15:03A laugh?

01:15:05A laugh? Was it a hyena?

01:15:07A rhino?

01:15:09Hyenas have one of the strongest jaws in the world.

01:15:11It's more than a dinosaur.

01:15:13It's a pretty serious combination.

01:15:15First option, run.

01:15:17This zebra seems to know what's going on.

01:15:19You start running while fighting

01:15:21against huge tofu plants

01:15:23and climbing on the roots of big jungle trees.

01:15:25You jump,

01:15:27you dive, you dodge

01:15:29and you're in the jungle.

01:15:31A beach. Perfect.

01:15:33Now you have time to think about what you just saw.

01:15:35What's the plan now?

01:15:37The ocean, palm trees, the sun

01:15:39and finally some fresh air from the sea.

01:15:41You take a deep breath

01:15:43and close your eyes.

01:15:45Silent like a feather,

01:15:47giant paws gently crushing the grass,

01:15:49the sound of an elegant tail,

01:15:51huge, grayish and strong,

01:15:53with incredibly long claws

01:15:55hidden in its big soft paws

01:15:57and a horrible head.

01:15:59You look at it a second time,

01:16:01still as disgusting.

01:16:03It looks like a naked skull with pointed teeth

01:16:05and warm, yellow eyes.

01:16:07This animal is not interested in you at all.

01:16:09It crouches,

01:16:11it looks ready to leap.

01:16:13Then the cat-o-zoor purrs

01:16:15and starts licking its fur.

01:16:17At least it didn't think

01:16:19you looked like a mouse, a stick,

01:16:21a ball, a cardboard box.

01:16:23Cats like the weirdest things.

01:16:25Not at the moment, no.

01:16:27The beach is suddenly filled

01:16:29with gigantic red crabs.

01:16:31There are hundreds of them,

01:16:33lying, resting with their long,

01:16:35clamped claws.

01:16:37Since when do crabs have ten eyes

01:16:39and four huge claws?

01:16:41As soon as you cover your mouth,

01:16:43but the scream still comes out.

01:16:45You run in the jungle

01:16:47and no, it's not the best idea.

01:16:49This time you run and you don't turn around.

01:16:51Your only goal is not to hear

01:16:53the clickety-clacking of the claws

01:16:55of the crab-o-zoo-raptor.

01:16:57But something has changed.

01:16:59The jungle has changed.

01:17:01The jungle seems to be transforming.

01:17:03There are no more roots,

01:17:05huge weird leaves,

01:17:07the air is fresher,

01:17:09the paths are a little wider.

01:17:11Apparently you are in a forest now.

01:17:13You come across a large open field

01:17:15with a large lake of dreams in the middle.

01:17:17A perfect place for a selfie.

01:17:19Well, except for all these dinosaurs

01:17:21A cricket crosses the lake.

01:17:23It is quite easy to recognize

01:17:25this elegant beast,

01:17:27even if its color is a little weird.

01:17:29It is a gray simudactyl

01:17:31with an S-shaped neck

01:17:33and all the rest.

01:17:35But this sign has undergone some improvements.

01:17:37A beak sharpened like a razor,

01:17:39large, powerful claws

01:17:41and eyes that seem to be able to spot a good meal

01:17:43from miles away.

01:17:45You are not a fish,

01:17:47so you should get by.

01:17:49From here, the lake is beautiful.

01:17:51There are water lilies everywhere,

01:17:53the size of a table.

01:17:55Water lilies, huge fleur-de-lis,

01:17:57huge croak-croak,

01:17:59great, a graposaurus.

01:18:01This thing is incredible.

01:18:03A huge individual jumps out of the water

01:18:05and lands like a ninja

01:18:07on a water lily.

01:18:09It looks like a gigantic rock

01:18:11covered with a rough, dark gray skin.

01:18:13There is no Prince Charming

01:18:15hiding in this thing.

01:18:17Oof, you are hiding behind a giant bush.

01:18:19This frog has a gigantic

01:18:21and unpleasant tongue.

01:18:23Even this delirious tongue

01:18:25could not save it from what is behind it.

01:18:27The head that floats

01:18:29of a giant crocodilosaurus,

01:18:31Raptor Rex Machinchose.

01:18:33It looks like a normal crocodile,

01:18:35but much bigger,

01:18:37as if it needed help to be more frightening.

01:18:39The graposaurus jumps out of the water

01:18:41and starts swimming

01:18:43with its huge hind legs.

01:18:45It starts to launch

01:18:47and very quickly they both disappear

01:18:49under the surface,

01:18:51hoping that this guy will get out of it.

01:18:53You almost feel sorry for this poor toad,

01:18:55but no time to think.

01:18:57The ground starts to shake.

01:18:59This is never a good sign.

01:19:01Some trees near you fall to the ground.

01:19:03It looks like a boat upside down.

01:19:05What is this thing?

01:19:07Oh, a tortoise!

01:19:09This guy must stop coffee and protein.

01:19:11Hmm, what is this noise?

01:19:13It gets louder and louder.

01:19:15Two things.

01:19:17One, it looks like a bee.

01:19:19Two, please, let it be just a normal size.

01:19:21But instead of a tiny flying insect,

01:19:23a Rex bee the size of a human

01:19:25lands on the shell of the giant tortoise.

01:19:27It has legs like an altairophile

01:19:29and its antennas look very pointy.

01:19:31If there is only one,

01:19:33it's good, with a little luck.

01:19:35Nowhere,

01:19:37we hear a horrible cry.

01:19:39Oh, let it stop for good.

01:19:41A gigantic shadow covers the ground

01:19:43and you open your eyes.

01:19:45It's a kind of dinosaur that looks like a bird.

01:19:47These things have an official name,

01:19:49but you have no idea what it is.

01:19:51You only see its blue feathers,

01:19:53a pointy beak,

01:19:55full of sharp teeth,

01:19:57and... what are these things

01:19:59coming out of its wings?

01:20:01The bird sees the Rex bee

01:20:03and goes down to get its treat.

01:20:05But the Rex bee is hiding

01:20:07under the turtle's shell.

01:20:09Something tells me

01:20:11that I wouldn't be as fast or smart

01:20:13if that happened to me.

01:20:15I would probably just...

01:20:17And boom, it happens.

01:20:19Its dark and scary eyes notice you from afar.

01:20:21You take a step back.

01:20:23Until now, none of the animals have noticed you.

01:20:25Crack! A frog cracks under your shoe

01:20:27and suddenly,

01:20:29dozens of gods land on you.

01:20:31Curious eyes, angry, hungry.

01:20:33Back to option 1.

01:20:35Run!

01:20:37Run as fast as you can,

01:20:39but everything seems useless.

01:20:41You arrive at a huge cliff

01:20:43with a river at the bottom.

01:20:45You close your eyes and jump.

01:20:47Boom! Your whole body shakes.

01:20:49You open your eyes.

01:20:51You are awake.

01:20:53It was just a nightmare, wasn't it?

01:20:55Wasn't it?

01:20:57Ah yes, driving through the countryside,

01:20:59windows down,

01:21:01with great music in the background.

01:21:03Car trips can be really cool.

01:21:05You can see a herd of cows through the window,

01:21:07but suddenly, one of them really stands out

01:21:09from the others. Literally.

01:21:11Next to it,

01:21:13the other cows look like black and white hamsters.

01:21:15The Guinness Book of World Records

01:21:17records the biggest cow as this specimen

01:21:19called Blossom.

01:21:21This big herb eater was 2 meters tall.

01:21:23Ah, someone better buy

01:21:25basketball shoes for this cow.

01:21:27The cow is on average 1.4 meters tall.

01:21:29Blossom must have felt like a giant.

01:21:31When you're this tall,

01:21:33you don't just hang out in a field

01:21:35eating grass.

01:21:37Blossom was the official host

01:21:39of a local hotel.

01:21:41Big Grand Jake.

01:21:43And believe me when I say

01:21:45that big is an euphemism.

01:21:47This guy became famous

01:21:49because he was the biggest horse in the world.

01:21:51He was 1.9 meters tall.

01:21:53We're definitely going to need a lot of

01:21:55basketball shoes.

01:21:57What a heel!

01:21:59Now,

01:22:01what about this little cutie?

01:22:03The smallest

01:22:05horse in the world.

01:22:07Her name is Thumbelina.

01:22:09What a pretty name!

01:22:11And she's about 0.5 meters tall.

01:22:13However, that didn't stop her from becoming famous.

01:22:15Oh, and the smallest horse in the world

01:22:17is called Bumble, which means

01:22:19bubble in Polish.

01:22:21He's 0.6 meters tall, but his heart is huge.

01:22:23He's very cute,

01:22:25and smaller than a bookshelf.

01:22:27I'm a person who loves dogs.

01:22:29Well, normal-sized dogs, let's say.

01:22:31A big Dane named Zos

01:22:33was officially the biggest dog in the world.

01:22:35He was 1.2 meters tall, and honestly,

01:22:37we felt like we were seeing a little horse.

01:22:39Imagine this face

01:22:41waking you up in the morning,

01:22:43and when you take him for a walk,

01:22:45you'd need a really strong leash.

01:22:47According to his owners,

01:22:49he was a nice giant,

01:22:51and normally he didn't do anything stupid, luckily.

01:22:53In addition, Zos had a really important job.

01:22:55He was a certified therapy dog.

01:22:57He spread his love and joy

01:22:59to everyone in need.

01:23:01Imagine a dog like this.

01:23:03You wouldn't need to give him a bowl of water every day.

01:23:05He could just drink

01:23:07straight from the tap.

01:23:09Cuddling would also be a great story.

01:23:11And can you imagine

01:23:13what this big guy could eat?

01:23:15Could he even sleep on your bed?

01:23:17So many questions.

01:23:19And if you're the kind of person who prefers cats,

01:23:21well, you'd better get ready.

01:23:23Anyway, this cat

01:23:25was named the longest domesticated cat in the world.

01:23:27His name is Baribel,

01:23:29which means clown,

01:23:31and he comes from a small town in Italy.

01:23:33He's also a nice giant,

01:23:35which is good news,

01:23:37because he's longer than a baseball bat.

01:23:39When he sees a picture,

01:23:41people usually think that this cat was photoshopped.

01:23:43He likes to lean against the sun

01:23:45near the window to look at the garden.

01:23:47When he hunts mice,

01:23:49he must feel like he's chasing ants.

01:23:51The former owners of this title

01:23:53were called Ludo and Stewie,

01:23:55the same breed as Baribel.

01:23:57It still makes a lot of cat hair

01:23:59on my mother's new couch.

01:24:01The next rabbit is named Darius.

01:24:03His long ears

01:24:05and his pretty nose in the shape of a button

01:24:07are not the reason why he is special.

01:24:09A normal rabbit measures about 35.6 cm,

01:24:11but Darius is a little over 127 cm.

01:24:13It's a big rabbit...

01:24:15dog.

01:24:17Darius grew up

01:24:19in a farm in England,

01:24:21and living in the open

01:24:23in the fields gave him a super cool personality.

01:24:25But feeding him must be difficult.

01:24:27Darius must be a machine

01:24:29to eat carrots.

01:24:31I don't want to go down this rabbit hole.

01:24:33Let's stop the cute things.

01:24:35It's time for the most exotic animals.

01:24:37Maybe even mythical.

01:24:39Myths are simply the way

01:24:41people explain incredible things,

01:24:43like the legend of the man with white lips,

01:24:45who just happened to be eating cheesecake.

01:24:47Rusted and fast under water,

01:24:49he is able to make a whole ship sink.

01:24:51The Kraken was famous

01:24:53for making ships disappear,

01:24:55according to legends.

01:24:57It's probably a sailor tale

01:24:59invented to scare new recruits.

01:25:01But the researchers may have found

01:25:03his little brother.

01:25:05The biggest squid ever found

01:25:07measured nearly 18.3 meters long.

01:25:09But the researchers forgot to film it.

01:25:11Oh no.

01:25:13The biggest squid ever filmed

01:25:15was about 7.6 meters long.

01:25:17It's as long as a motorhome.

01:25:19Scientists think it could have

01:25:21bigger ones, but they are a little shy

01:25:23in front of the cameras.

01:25:25The big white shark scares all

01:25:27sea animals.

01:25:29It is called the queen of the ocean,

01:25:31but it is not one of its kind and sweet queens.

01:25:33Oh, far from it.

01:25:35Scientists were able to mark it

01:25:37to study it more.

01:25:39This queen weighs about 1,587 kilos.

01:25:41It's like 6 motorcycles

01:25:43or 14,000 hot dogs.

01:25:45It was caught in the waters

01:25:47off New Scotland

01:25:49by a team of terrified researchers.

01:25:51Fortunately, sharks only walk in the ocean.

01:25:53Unless it's an episode

01:25:55of Ninja Warriors with sharks.

01:25:57That was the biggest,

01:25:59now the longest.

01:26:01Good guess, but no,

01:26:03it's not a snake at all.

01:26:05But it's as long as a football field.

01:26:07This animal was discovered

01:26:09in the deep waters off Australia.

01:26:11And listen to this.

01:26:13Scientists say it's not even a creature.

01:26:15It just looks like a single beast.

01:26:17But in fact, it is an entire colony

01:26:19that clones and multiplies

01:26:21until it becomes

01:26:23even bigger.

01:26:25It's a technical name and ...

01:26:27The next animal

01:26:29can move on land

01:26:31and on water.

01:26:33Do not be fooled by its short and thin legs.

01:26:35A crocodile can run as fast as a man on land.

01:26:37So if you run

01:26:39against these sprinters,

01:26:41try to climb as high as possible

01:26:43in a tree.

01:26:45Crocodiles cannot climb trees.

01:26:47But you can be sure

01:26:49that they will wait for you

01:26:51when you go down.

01:26:53They are also the heaviest reptiles in the world.

01:26:55An adult can weigh about

01:26:57as much as two small cars.

01:26:59The largest in captivity

01:27:01was a sea crocodile in the Philippines.

01:27:03It was called Lolong

01:27:05and was 6.1 meters long.

01:27:07It weighed about

01:27:09as much as a whole bunch of teeth.

01:27:11Then comes another reptile,

01:27:13a gigantic snake from Malaysia.

01:27:15Here's the story.

01:27:17Workers at a construction site

01:27:19were on break and it was very hot.

01:27:21They noticed something.

01:27:23Was it a big pipe?

01:27:25Well, this time it was a snake.

01:27:27They took out the longest python

01:27:29ever captured.

01:27:31It took more than five men

01:27:33to get it out of the site

01:27:35and it weighed about 249 kilos.

01:27:37It's only a little shorter

01:27:39than a big lamp.

01:27:41The previous record of the longest snake

01:27:43in captivity was the famous jellyfish.

01:27:45It was also a python.

01:27:47This kind of snake can eat

01:27:49all its weight for breakfast.

01:27:51It's like eating 280 hamburgers.

01:27:53I absolutely don't want fries with that.

01:27:55Back to the water.

01:27:57The biggest blue catfish ever captured.

01:27:59The Andersons caught it

01:28:01in Virginia in 2011

01:28:03and it's been around since then.

01:28:05With a surprising weight of 65 kilos,

01:28:07it's like fishing a washing machine

01:28:09in a lake on a small boat.

01:28:11That's why it took the father

01:28:13and the son to get it out on the bridge.

01:28:15The honorable mention is given

01:28:17to the oldest cat in the world.

01:28:19No, it's not a lion or a tiger,

01:28:21but a mix of the two.

01:28:23It's a lygre.

01:28:25The lygre does not exist in nature

01:28:27since lions and tigers live

01:28:29in totally different regions of the world.

01:28:31Hercules holds this particular record.

01:28:33With more than 408 kilos,

01:28:35he is the largest carnivorous mammal in the world.

01:28:37He is as long as his mother,

01:28:39a tiger, and as heavy as his father,

01:28:41a lion called Arthur.

01:28:43Do you want to know what it's called

01:28:45when the mother is a lion

01:28:47and the father is a tiger?

01:28:49A tigron.

01:28:51They are much less common than the lygre,

01:28:53but they are just as weird.

01:28:55It looks like the mythical creature

01:28:57of ancient Greece, the chimera.

01:28:59And some stories say

01:29:01that it even had bat wings.

01:29:03Oh, and it spit fire too.

01:29:05It would take a whole bunch of Spartan

01:29:07firefighters to take care of this thing.

01:29:09But we could probably

01:29:11have a great party with a barbecue.

01:29:13What about us humans?

01:29:15The prize is awarded to Robert Wadlow

01:29:17in Illinois.

01:29:19He was 2.5 meters tall

01:29:21and he could carry his father at the age of 9.

01:29:23Let's think about it for a moment.

01:29:25He ate

01:29:27more than 8,000 calories per day

01:29:29and his pulse rate was 71.

01:29:57the most frightening sharks

01:29:59that exist.

01:30:01But in fact, they are not really

01:30:03able to harm anyone.

01:30:05Pelican sharks are filterers,

01:30:07just like whaling whales.

01:30:09They open their big mouths

01:30:11to swallow plankton

01:30:13and not even teeth.

01:30:15It is late at night

01:30:17in the jungle of Central America.

01:30:19You are in nature to observe

01:30:21the birds and you hear

01:30:23a bat. Excited, you look

01:30:25out of your worst nightmares.

01:30:27Don't scream, you're going to scare them.

01:30:29It's a bat, all wrinkled,

01:30:31who is perfectly harmless

01:30:33and who is not interested in you.

01:30:35They are frugivorous bats

01:30:37and the wrinkles on their faces

01:30:39allow them to collect pieces of fruit

01:30:41and juice to eat later.

01:30:43Besides, their Latin name,

01:30:45Centurio Senex, was given to them

01:30:47because of their resemblance

01:30:49to centennial humans.

01:30:51You walk in a Nepalese national park

01:30:53in a river, but suddenly

01:30:55you are frozen in terror.

01:30:57A crocodile looks at you

01:30:59straight in the eye

01:31:01a few meters away.

01:31:03Then he raises his muzzle above the water

01:31:05and you breathe again relieved.

01:31:07It's a ganja seagull.

01:31:09These reptiles have a long and narrow muzzle

01:31:11that allows them to effectively capture

01:31:13fish while preventing them

01:31:15from hunting any other prey.

01:31:17Although they are still carnivores,

01:31:19seagulls are quite shy

01:31:21and hunt quickly in the sight of humans.

01:31:23At present, there are no more than

01:31:25a thousand of these crocodiles

01:31:27in the whole world.

01:31:29So drop it, especially if it's a seagull.

01:31:31Ha ha ha!

01:31:33You dig in your garden

01:31:35and you notice that something moves

01:31:37on your shovel.

01:31:39You look closer and you drop the tool

01:31:41with horror.

01:31:43A small creature that looks like

01:31:45a mean alien rushes

01:31:47into an earthworm in the ground.

01:31:49It's just a starfish.

01:31:51These creatures have a particular muzzle

01:31:53that seems to have exploded from the inside.

01:31:55Their eyes are small and inefficient,

01:31:57so this kind of star on their nose

01:31:59helps them a lot to move

01:32:01and look for food.

01:32:03It is still moving,

01:32:05touching everything it can reach

01:32:07with its tentacles as if they were

01:32:09tiny fingers.

01:32:11Oh, are you swimming again in the ocean?

01:32:13Well, look to your right.

01:32:15There is a real shark

01:32:17with teeth running straight at you.

01:32:19No, don't panic.

01:32:21It's just a bull shark,

01:32:23and it has nothing to do with a bull.

01:32:25It is a piscivorous shark

01:32:27that swims slowly in the seas

01:32:29and hunts its prey from time to time.

01:32:31We have never reported attacks on humans,

01:32:33but it always has pointy teeth,

01:32:35so don't try to touch it just in case.

01:32:37It may seem calm,

01:32:39but you don't want it to gnaw at you,

01:32:41do you?

01:32:43Well, from the ocean to the desert,

01:32:45there is a lot of prey

01:32:47that you may be able to find.

01:32:49So you start digging in the ground

01:32:51and you come across a creature

01:32:53from the depths of the earth,

01:32:55all covered in thorns.

01:32:57It looks at you suspiciously

01:32:59and slides away,

01:33:01because it is a horned devil.

01:33:03Despite its disturbing name,

01:33:05this lizard is harmless to humans.

01:33:07The horns-shaped bones

01:33:09it wears on its skin

01:33:11protect it from predators

01:33:13Now, if you are arachnophobe,

01:33:15it won't be of much use to you,

01:33:17but the felines you can meet

01:33:19in North and South America,

01:33:21as well as in Asia and Africa,

01:33:23are more afraid of you than of them.

01:33:25Tell yourself that.

01:33:27These nightmarish creatures

01:33:29have no dart and don't even bite

01:33:31when they are threatened.

01:33:33The worst they can do,

01:33:35and only if you swallow them,

01:33:37but why would you do the same,

01:33:39is to prick you with their front paw,

01:33:41because they are very affectionate

01:33:43towards their owner.

01:33:45Yeah...

01:33:47If you ever come across a terrier

01:33:49where there is a bald creature

01:33:51with big teeth watching you,

01:33:53don't worry and leave it alone.

01:33:55The naked rattlesnakes

01:33:57are the sphinx cats among rodents.

01:33:59They are close relatives of rattlesnakes,

01:34:01but they are naked,

01:34:03and they are fascinating in themselves.

01:34:05As they live almost completely underground,

01:34:07they have almost cold blood,

01:34:09but they can live

01:34:11at any outside temperature,

01:34:13and their wrinkled and flaccid skin

01:34:15does not feel any pain,

01:34:17so that the pointy teeth of others

01:34:19do not scare the naked rattlesnakes.

01:34:21You are once again lost in the jungle,

01:34:23this time in Madagascar.

01:34:25Poor you, definitely.

01:34:27Night has fallen and you are looking for shelter,

01:34:29but when you think you have found

01:34:31a suitable tree to build a shelter,

01:34:33you are frozen in terror.

01:34:35A black hand with long fingers

01:34:37appears on a branch of the tree

01:34:39just above you,

01:34:41with two huge yellow eyes

01:34:43watching you.

01:34:45Then you see a pale face,

01:34:47and you realize that it is just a Lemur

01:34:49a Haiaiaiai to be more precise.

01:34:51This creature is native to Madagascar

01:34:53and comes out only at night,

01:34:55so you have to be lucky to see it.

01:34:57It plays the role of a greeler

01:34:59in the tropical forests.

01:35:01It strikes the trees to find the insects

01:35:03and uses its long fingers

01:35:05Fatigué d'avoir peur, tu cherches à revenir à la maison, mais les horreurs ne sont pas encore finies.

01:35:10Un grand serpent rouge et blanc se dresse sur ton chemin. Il siffle et attend que tu bouges.

01:35:16Tu sais que c'est un serpent corail, une espèce vénimeuse très dangereuse.

01:35:20Tu t'arrêtes, et ce n'est que lorsqu'il s'éloigne enfin en glissant que tu réalises qu'il s'agissait en fait d'un serpent laitier de l'Est.

01:35:27Ils imitent souvent les serpents vénimeux, pas seulement les serpents corail, pour se protéger des prédateurs.

01:35:32Cependant, si tu n'es pas un expert en serpents, il est toujours préférable de rester à l'écart.

01:35:38Bon, cette créature va s'inviter dans tes rêves les plus sombres, un millepade géant africain.

01:35:44Il est grand, noir, brillant, et il a des centaines de petites pattes pour ramper.

01:35:50Et pourtant, s'il avait des grands yeux ronds, il pourrait même être plutôt mignon.

01:35:54C'est peut-être pour cela que tant de gens les gardent comme animaux de compagnie.

01:35:58Ça, c'est parce qu'ils vivent généralement jusqu'à dix ans.

01:36:01Les millepades géants ne peuvent pas vraiment mordre.

01:36:03Leur seule défense est de se recroqueviller en une boule dure et de sécréter un liquide irritant pour les pores de sa peau.

01:36:10Si tu oses le toucher, ne te frotte pas les yeux ou le nez par la suite.

01:36:14C'est assez désagréable.

01:36:16L'araignée Goliath est un autre animal de compagnie rampant très populaire.

01:36:21Il n'est pas dangereux pour les humains, même s'il ressemble à ton pire cauchemar.

01:36:25C'est l'une des plus grandes araignées du monde.

01:36:27Et comme son nom l'indique en anglais, Goliath birdeater, soit mangeur d'oiseaux,

01:36:32elle chasse parfois de petits oiseaux pour se nourrir.

01:36:34Mais elles ne font pas partie de son régime alimentaire habituel.

01:36:37L'araignée préfère les vers et les amphibiens.

01:36:40Cependant, elle évite de l'effrayer.

01:36:42Elle peut toujours mordre ou libérer des poils en cas de légitime défense.

01:36:46La piqûre est semblable à celle d'une guêpe et les poils peuvent provoquer une grave irritation de la peau.

01:36:52Mais la plupart du temps, ce gentil géant est juste timide et s'éloigne en rampant quand il te voit.

01:36:59Oh mon dieu, un autre serpent s'approche de toi ! Et vite !

01:37:02Tu es sur le point de faire demi-tour et de courir,

01:37:05quand tu vois une forme avec huit pattes qui coupe le chemin du serpent et saute dessus.

01:37:09C'est un autre arachnide et il a l'air encore plus terrifiant que le serpent.

01:37:13C'est un solifuge.

01:37:15Ce n'est pas vraiment une araignée ni un scorpion.

01:37:17Ces créatures appartiennent à une famille distincte.

01:37:20Elles sont devenues l'objet de nombreuses légendes urbaines,

01:37:23mais en fait, elles n'ont même pas de venin.

01:37:25Bien sûr, elles peuvent mordre et leurs mâchoires sont assez puissantes.

01:37:29Mais les solifuges ne peuvent pas faire beaucoup de mal à un humain à part le mordre.

01:37:33Elles se cachent dans le sable et les terriers pour sauter sur des lézards,

01:37:36des invertébrés et oui, même des serpents.

01:37:40Et maintenant, imagine un cloporte.

01:37:42Pas vraiment une beauté, mais comme il est petit, ça va.

01:37:46Mais s'il était dix fois plus gros, non, ça n'irait pas du tout.

01:37:49Pourtant, une créature pareille existe.

01:37:51C'est un batinôme géant.

01:37:53Heureusement, il se tapit dans des eaux profondes sombres et froides,

01:37:57donc il n'apparaît jamais dans ton jardin.

01:37:59Les batinômes géants atteignent une taille pareille

01:38:02à cause de ce qu'on appelle le gigantisme des profondeurs.

01:38:05Les créatures des profondeurs doivent supporter une grande pression de l'eau,

01:38:09des températures extrêmement froides et peu de nourriture,

01:38:12ce qui ralentit leur métabolisme.

01:38:14Les isopodes ne se déplacent pas beaucoup

01:38:16et, le plus souvent, ils attendent qu'un petit insecte ou un crustacé

01:38:20rampe à leur portée pour qu'ils puissent le croquer.

01:38:23Et même si, vu d'en bas, il ressemble à une créature horrible

01:38:26avec une quantité de pattes,

01:38:27il ne peut pas te faire de mal, même s'il le voulait.

01:38:30Il suffit de le caresser.

01:38:32Vas-y.

01:38:34Lion, chien, chat,

01:38:36tous ces mammifères dorment dans des positions plutôt confortables.

01:38:40Mais pas les baleines.

01:38:41Elles ressemblent à des miches de pain géantes qui flottent,

01:38:45scènes dont un plongeur a été témoin par hasard dans la mer des Caraïbes.

01:38:49Si baleine se tenait debout, la queue pointait vers le bas,

01:38:53à une profondeur d'environ 20 mètres sous la surface.

01:38:56Les scientifiques ont découvert que lorsque les cachalots font une sieste,

01:39:00ils restent dans cette position pendant 10 à 15 minutes.

01:39:02Ils ne bougent pas et ne respirent pas.

01:39:05Mais ces créatures ne passent que 7% de leur temps à dormir,

01:39:08soit beaucoup moins que les autres mammifères.

01:39:10En général, elles se reposent paisiblement dans l'eau

01:39:13ou se détendent en nageant lentement à côté d'autres animaux marins.

01:39:16Lorsqu'ils bougent et dorment en même temps,

01:39:18ils sont en train de faire une sieste.

01:39:20Ces animaux ne peuvent pas aller trop profondément

01:39:23et doivent rester près de la surface.

01:39:25Les grands requins blancs dorment et chassent à de plus grandes profondeurs,

01:39:29ce qui signifie qu'ils ont moins de soucis pendant leur sieste.

01:39:32En plus, plus on s'enfonce, plus il fait froid.

01:39:35Les baleines ont besoin d'environnements plus chauds

01:39:38qui les aident à maintenir la température de leur corps imposant.

01:39:41Lorsqu'ils sont seuls, les dauphins entrent dans une phase de sommeil profond.

01:39:45Cela se produit généralement la nuit et ne dure que quelques heures à la fois.

01:39:49Quand ils dorent, l'animal flotte à la surface.

01:39:51Il éteint la moitié de son cerveau.

01:39:53Hé, je fais pareil !

01:39:55Ainsi que l'œil opposé.

01:39:57L'autre moitié reste à un faible niveau d'alerte.

01:40:00Éveillé est prêt à réagir si un visiteur indésirable s'approche.

01:40:04La partie du cerveau qui est éveillée envoie également des signaux

01:40:07lorsqu'il est temps de remonter à la surface pour prendre une inspiration.

01:40:11Les mammifères marins ont un évent.

01:40:13C'est un lambeau de peau qu'ils peuvent ouvrir et fermer à leur guise.

01:40:17Les humains respirent de façon automatique.

01:40:19Ton corps sait ce qu'il doit faire même quand tu dors.

01:40:22Mais les baleines et les dauphins ont un système de respiration volontaire.

01:40:25Cela signifie qu'ils doivent aller consciemment à la surface pour respirer.

01:40:29Et une partie de leur cerveau doit toujours être éveillée

01:40:31pour informer l'animal qu'il est temps de remonter.

01:40:34Les baleines et les dauphins peuvent retenir leur souffle bien plus longtemps

01:40:37que les autres espèces.

01:40:38Ils ont également une plus grande tolérance au dioxyde de carbone

01:40:41et peuvent absorber plus d'air.

01:40:43Leurs globules rouges stockent également plus d'oxygène.

01:40:46Le sang des baleines et des dauphins ne va que dans les parties du corps

01:40:49qui ont réellement besoin d'oxygène.

01:40:51Si une baleine n'utilise que son cerveau, son cœur, ses nageoires

01:40:54ou d'autres muscles nécessaires à la nage,

01:40:56à ce moment-là, ce seront également les seules parties du corps

01:40:59qui recevront de l'oxygène.

01:41:01La digestion ou d'autres fonctions peuvent attendre.

01:41:03L'océan n'est pas un endroit où on peut se détendre et s'endormir paisiblement.

01:41:07Pendant leur sommeil, les poissons réduisent leur activité.

01:41:11Leur métabolisme devient lent.

01:41:13Certains d'entre eux continuent à flotter au même endroit.

01:41:16D'autres trouvent un endroit plus sûr, parmi les coraux ou dans la boue.

01:41:20Très tôt dans leur vie, les dauphins apprennent à y mettre un sifflement unique

01:41:24qui aide les autres membres de leur groupe à les identifier.

01:41:28Cela signifie que ces sifflements spécifiques sont leur nom.

01:41:31Et les dauphins y répondent.

01:41:33Les palourdes ont des pieds.

01:41:35Ça ressemble à une grande langue qui dépasse parfois de la coquille.

01:41:38Mais c'est en fait le pied.

01:41:39Et il est relativement long par rapport à la longueur de l'animal.

01:41:43Les palourdes utilisent ce membre pour se terrer dans le sable.

01:41:46La baleine bleue est le plus grand animal vivant.

01:41:50Et elle est aussi plus grande que l'étaient la majorité des dinosaures.

01:41:53Elle peut atteindre plus de 30 mètres de long et peser près de 200 tonnes.

01:41:58Cela équivaut à 50 éléphants adultes.

01:42:01La langue d'une baleine bleue peut à elle seule peser plus qu'un éléphant.

01:42:04Un tel géant a besoin de beaucoup manger.

01:42:07Un demi-million de calories en une seule bouchée.

01:42:10Le cœur de la baleine bleue fait la taille d'une petite voiture épaisse 590 kilos.

01:42:15Pour faire circuler le sang dans un corps aussi gigantesque.

01:42:18Les battements du cœur sont si forts qu'on peut les entendre même à 3 km de distance.

01:42:23Le pouls d'une baleine ne bat que 8 à 10 fois par minute.

01:42:26La baleine est l'une des créatures les plus bruyantes qui existent.

01:42:30Son cri peut atteindre 180 décibels, ce qui est aussi fort qu'un avion à réaction.

01:42:35Près de 95% du corps de la méduse est constitué d'eau.

01:42:40À titre de comparaison, le corps humain est composé à 60% d'eau.

01:42:44Ce n'est probablement pas une surprise puisque les méduses n'ont pas de cœur,

01:42:47de sang, d'yeux ou de cerveau.

01:42:50Les autres 5% du poids de leur corps sont constitués de protéines,

01:42:54de muscles et de cellules nerveuses.

01:42:57Les méduses existent depuis plus de 500 millions d'années.

01:43:00Elles sont donc plus anciennes que les dinosaures.

01:43:02Ces créatures n'ont pas beaucoup changé,

01:43:05et les méduses d'aujourd'hui ressemblent beaucoup à leurs ancêtres.

01:43:08Ces créatures vivent dans l'océan,

01:43:10mais en 1991, plus de 2000 polypes de méduses ont été emmenées dans l'espace.

01:43:16Les scientifiques voulaient voir comment elles réagiraient dans un environnement sans gravité.

01:43:20Les méduses se sont reproduites et ont créé 60 000 nouveaux polypes.

01:43:24Mais malheureusement, ceux-ci ne pouvaient pas fonctionner normalement après leur retour sur Terre.

01:43:29Une espèce de méduse peut littéralement vivre éternellement.

01:43:31Quand elle vieillit, la créature descend au fond de la mer pour redevenir un polype.

01:43:36Et ce polype se transforme en une nouvelle méduse avec le même génome.

01:43:40Les requins du Groenland peuvent vivre 500 ans.

01:43:43Il s'agit d'un animal dont la durée de vie est presque la plus longue connue de tous les vertébrés.

01:43:48Les cachalots sont des créatures sociables qui passent leur vie entourées de leur famille.

01:43:52Ces animaux se soutiennent mutuellement et ont des amis proches dont ils se souviennent bien,

01:43:57même s'ils ne se voient pas pendant longtemps.

01:43:59Les anguilles électriques ont de petits yeux qui ne sont pas très efficaces dans les environnements sans lumière.

01:44:04Elles se fient donc surtout à leurs organes électriques.

01:44:07Ceux-ci sont constitués de 6000 cellules.

01:44:10Les anguilles les utilisent pour stocker de l'énergie, comme des batteries.

01:44:13Ces créatures utilisent l'électricité, comme les chauves-souris utilisent leur radar,

01:44:17ou les dauphins, leur sonar.

01:44:19Une anguille peut également produire suffisamment d'électricité pour alimenter un panneau d'ampoule électrique.

01:44:26Il existe un petit poisson arché, tropical, qui peut apprendre à reconnaître les visages humains.

01:44:31Ce poisson a la capacité intéressante de cracher de petits jets d'eau par sa bouche.

01:44:37Les chercheurs ont montré au poisson les images de deux visages différents placés côte à côte.

01:44:42L'un était inconnu, l'autre familier.

01:44:45Le poisson était censé cracher de l'eau sur le visage familier.

01:44:48La créature a fait le bon choix dans plus de 80% des cas.

01:44:52Chaque année en hiver, les grands requins blancs qui vivent le long de la côte californienne disparaissent.

01:44:57C'est comme s'ils prenaient des vacances pendant 30 à 40 jours.

01:45:00Les animaux se rendent à un point situé à mi-chemin entre Hawaï et le Mexique.

01:45:05Ils le font pour se nourrir, se détendre ou passer du temps avec leurs potes d'autres régions.

01:45:09L'endroit est maintenant appelé le café des requins blancs.

01:45:12Certains types de requins, comme les makos, les requins baleines ou les requins blancs,

01:45:16respirent d'une manière très spécifique.

01:45:19Cela les oblige à nager sans arrêt.

01:45:21Ils doivent également se déplacer rapidement et avec la bouche ouverte.

01:45:24Ainsi, l'oxygène peut entrer et atteindre leurs branchies.

01:45:27Les éponges ou spongières font partie des animaux les plus primitifs.

01:45:31Ils sont immobiles, n'ont pas de bouche, d'yeux, d'os, de cerveau, de cœur, de poumon ni tout autre organe.

01:45:37Et pourtant, ils sont vivants.

01:45:39Il existe une licorne des mers.

01:45:41C'est un animal appelé narval.

01:45:43Sa corne est en fait une dent qui peut atteindre 3 mètres de long.

01:45:47Les lamantins, également appelés vaches de mer, sont des parents éloignés des éléphants.

01:45:51Leur poids peut atteindre 450 kilos.

01:45:54Ces créatures sont végétariennes et ont besoin de manger chaque jour environ 10% de leur poids total.

01:45:59C'est beaucoup de salades marines.

01:46:01Dans certains cas, les lamantins partagent l'espace avec les alligators.

01:46:05Mais ils s'entendent plutôt bien.

01:46:06Tu peux même trouver une photo de Floride où un alligator monte sur le dos d'un lamantin.

01:46:11Les poissons-grenouilles ont des nageoires spéciales qui aident ces créatures à marcher sur le sable.

01:46:16Elles sont très utiles dans les eaux peu profondes.

01:46:20Un solé nostomidé, ou poisson fantôme, est difficile à voir.

01:46:24Mais une fois que tu l'as repéré, tu vas être très surpris.

01:46:27Sa tête représente plus de 40% de son corps.

01:46:30Les crabes n'ont pas envie de perdre du temps avec des formalités telles que mettre la nourriture dans leur bouche.

01:46:35C'est pourquoi ils la gouttent avec leurs pattes, là où se trouvent leurs papilles gustatives.

01:46:39Les iguanes marins sont les seuls lézards de notre planète qui aiment passer du temps dans l'océan,

01:46:44même s'ils vivent principalement sur terre.

01:46:46Ce sont des herbivores qui se nourrissent dans les eaux peu profondes et nagent comme des serpents.

01:46:51Les iguanes utilisent leurs longues griffes pour s'accrocher au fond lorsqu'ils ont besoin de manger.

01:46:56Les tortues vertes peuvent parcourir plus de 12 250 km lors de leur migration.

01:47:02Elles essayent de trouver l'endroit idéal pour pondre leurs œufs.

01:47:05Les pingouins volent en quelque sorte lorsqu'ils sont sous l'eau, atteignant une vitesse de 40 km heure.

01:47:10Il y a plus de 500 millions d'années, c'est ce que j'ai entendu, moi je n'étais pas là à l'époque,

01:47:15les vers d'eau profonde et les humains avaient un ancêtre commun.

01:47:19Nous partageons donc encore 70% de nos gènes avec ces créatures.

01:47:23Et avec les étoiles de mer, les calmars et les pieuvres, l'océan couvre plus de 70% de notre planète.

01:47:30Et plus de 80% de celui-ci est inexploré, plus d'un million d'espèces y vivent.

01:47:35Mais il n'y a pas que des animaux, 3 millions d'épaves reposent au fond de l'océan,

01:47:39recelant de mystérieuses histoires, beaucoup d'entre elles restent encore à découvrir.

01:48:09Il est important de comprendre pourquoi ils les font et s'il y a lieu de s'inquiéter.

01:48:14Pourquoi mon chien lèche-t-il les meubles?

01:48:18Tu t'affales sur le canapé pour regarder un film et tu te retrouves assis sur une tâche humide.

01:48:23Non, Fido n'a pas eu d'accident, il a simplement léché cet endroit précis pendant les 20 dernières minutes.

01:48:30L'American Kennel Association affirme que dans la plupart des cas, il ne faut pas s'inquiéter.

01:48:36Souvent, un chien lèche les meubles par ennui.

01:48:38C'est simplement un moyen de passer le temps quand il n'a rien d'autre à faire.

01:48:42L'astuce consiste à s'assurer que ton animal dispose de suffisamment de jouets et d'attention de ta part pour le tenir occupé.

01:48:49D'autre part, il se peut qu'il lèche les meubles en raison de son anxiété ou de son stress.

01:48:53Si son environnement ou sa routine a subi des changements importants, l'animal peut se sentir nerveux et déstabilisé.

01:49:00Ton horaire de travail est peut-être différent ou une nouvelle personne a peut-être emménagé dans la maison.

01:49:05Ce geste répétitif de léchage a une fonction apaisante pour un chien.

01:49:09À mesure qu'il s'adapte, cela devrait se produire moins souvent.

01:49:13Si le léchage est constant, agressif et difficile à arrêter, une visite chez le vétérinaire s'impose.

01:49:18Cela peut indiquer un problème plus grave.

01:49:21Un professionnel peut déterminer si des problèmes de santé sous-jacents sont à l'origine de ce comportement.

01:49:27Il en va de même lorsque ton chien se lèche constamment les pattes.

01:49:30S'il s'agit d'un phénomène isolé, il n'y a pas lieu de s'inquiéter.

01:49:34Mais si cela se produit souvent, cela peut indiquer une douleur ou une gêne à cet endroit.

01:49:39Même si ton chien est en bonne santé, trop de léchage peut provoquer des rougeurs et des douleurs à cet endroit.

01:49:47Pourquoi mon chien gratte-t-il le sol après être allé aux toilettes?

01:49:51Connu sous le nom de grattage du sol, c'est une chose très courante chez la plupart des canins.

01:49:56En fait, les loups et les coyotes le font aussi.

01:49:59Cela permet de marquer le territoire du chien en faisant savoir aux autres que

01:50:03cela signifie en langage canin « j'étais là ».

01:50:07Le grattage permet non seulement de créer une marque visuelle sur le sol,

01:50:11mais aussi de libérer des phéromones grâce aux glandes spéciales situées dans ses pattes.

01:50:15Les autres chiens peuvent sentir et déchiffrer ces phéromones.

01:50:18Et pour toi qui ne possède pas de chien,

01:50:21tu sais ces panneaux que tu as mis pour empêcher les chiens d'utiliser ta pelouse comme toilette.

01:50:25Sache qu'ils ne fonctionnent pas. Les chiens ne savent pas lire.

01:50:28Mon chien prend de la nourriture dans son bol et la mange à plusieurs mètres. Ce n'est pas normal.

01:50:33En fait, si, ça l'est. C'est simplement l'instinct qui entre en jeu.

01:50:38À l'état sauvage, les chiens vivaient avec d'autres chiens dans un groupe ou une meute.

01:50:42Lorsqu'il y avait de la nourriture,

01:50:44les animaux moins dominants devaient faire beaucoup d'efforts pour obtenir aussi quelque chose à manger.

01:50:48Cela signifiait souvent s'emparer d'un morceau de viande

01:50:51et partir rapidement vers un endroit plus sûr pour finir son repas en paix.

01:50:55Ton chien répète tout simplement le comportement de ses ancêtres.

01:50:58L'autre possibilité est le bruit.

01:51:00Certains chiens peuvent être tout bonnement effrayés par le cliquetis de leur collier contre un bol en métal, par exemple.

01:51:06Essaie de remplacer le bol par un bol en plastique pour voir si cela fait une différence.

01:51:11Mais mon chien mange aussi de l'herbe. Est-ce qu'il ne se sent pas bien?

01:51:14C'est une situation plus compliquée.

01:51:16D'abord, ne panique pas. Beaucoup de chiens le font.

01:51:19Certains d'entre eux mangent de l'herbe pour la même raison que tu ajoutes des fibres à ton alimentation.

01:51:23Cela fournit des fibres supplémentaires au système digestif, ce qui l'aide à fonctionner correctement.

01:51:28Comme pour le léchage des meubles, il peut également s'agir d'un moyen de lutter contre l'ennui.

01:51:33Si un chien n'a rien d'autre à faire, s'agripper et tirer sur ses trucs verts peut être le seul moyen de se distraire.

01:51:39Mais manger de l'herbe, même si c'est normal, est problématique.

01:51:43Tu ne sais pas ce qu'il y a dans cette herbe.

01:51:45Cela peut être n'importe quoi, par exemple des herbicides et des pesticides.

01:51:49Elles peuvent être très mauvaises pour la santé de ton chien.

01:51:52Détourne son attention lorsqu'il essaie de manger de l'herbe en lui donnant un signal verbal et une friandise pour le renforcer.

01:51:59Mon chien se roule dans des endroits qui puent sur le sol, c'est dégoûtant.

01:52:03L'autre chose étrange que mon chien fait, c'est de se rouler par terre sur des tas qui puent, c'est dégoûtant.

01:52:08C'est peut-être dégoûtant pour toi, mais c'est naturel pour ton chien.

01:52:11Il est possible que les chiens, ainsi que les loups et les coyotes, fassent cela pour dissimuler leur odeur naturelle.

01:52:17Ils se couvrent d'une odeur qui peut les cacher de leurs rivaux ou d'un repas potentiel.

01:52:21Il est également possible qu'ils le fassent pour rapporter l'odeur à leur meute afin de communiquer quelque chose qu'ils ont trouvé.

01:52:27C'est comme partager sa journée avec ses amis, mais par l'odeur au lieu des mots.

01:52:32Que sont les zoomies ?

01:52:34Selon la vétérinaire Sarah Wootten, les zoomies se réfèrent à de courtes périodes d'hyperactivité.

01:52:40Tu sais, quand ton chien zoome littéralement comme un fou pendant un moment, puis se calme et revient à la normale.

01:52:47Le terme officiel pour ce comportement est « frappe », de l'anglais « période d'activité aléatoire frénétique ».

01:52:53Mais « zoomies » est beaucoup plus amusant à dire.

01:52:56Les chiens font cela parce qu'ils ont de l'énergie refoulée, qu'il y a besoin de sortir.

01:53:00Ils ont peut-être été seuls toute la journée ou viennent de prendre un bain.

01:53:04Maintenant qu'ils sont libres, ils veulent fêter ça. C'est souvent le signe d'un animal très heureux.

01:53:09La seule inquiétude que suscite les zoomies est que ton fido risque de heurter quelqu'un ou quelque chose et de se blesser.

01:53:15Tu peux le rediriger vers une zone plus sécurisée si nécessaire.

01:53:19De plus, augmenter la quantité d'exercices et de stimulation mentale que ton chien reçoit tout au long de la journée peut réduire ses moments d'abandon sauvage.

01:53:28Ok, mais pourquoi les chiens se reniflent-ils le derrière ?

01:53:32C'est probablement le comportement qui nous est le plus familier.

01:53:35Il semble étrange lorsque les chiens le font avec d'autres chiens et embarrassant lorsqu'ils le font avec ta belle-mère.

01:53:41Mais tous les chiens le font. Ces animaux peuvent recueillir beaucoup d'informations grâce à leur nez.

01:53:46En fait, leur odorat peut être près de 100 000 fois meilleur que le nôtre, car les chiens possèdent 150 millions de récepteurs olfactifs dans leur nez.

01:53:54Nous n'en avons que 5 millions.

01:53:57Et 30% du cerveau d'un chien est spécifiquement dédié au traitement des odeurs.

01:54:02Sur la base de l'odeur, le chien peut rapidement tout déterminer.

01:54:06Du sexe à l'humeur en passant par l'amabilité et la santé.

01:54:10C'est presque comme un super-pouvoir.

01:54:14Je laisse toujours un chien étranger renifler ma main en premier.

01:54:17La société Eureka Dog Services, spécialisée dans le dressage des chiens, affirme que c'est une chose terrible à faire.

01:54:24Cela peut en fait faire en sorte que certains chiens se sentent menacés.

01:54:28Et ce n'est pas étonnant.

01:54:30Tu les domines et tu leur mets ta main dans la figure.

01:54:33D'abord, demande la permission au propriétaire.

01:54:35Si tu as le feu vert, incline ton corps et ton visage à 45 degrés par rapport à l'animal et souris.

01:54:41Ensuite, laisse à l'animal le temps de s'approcher de toi.

01:54:45Le chien peut se pencher en avant en gardant ses pattes arrières plantées en permanence.

01:54:49C'est juste au cas où tu serais dangereux.

01:54:51De cette façon, il peut s'éloigner rapidement de toi si nécessaire.

01:54:55Mon chien doit aimer les gens.

01:54:56Il demande toujours des caresses sur le ventre.

01:54:59Bien que ton chien puisse aimer recevoir des gratouilles sur son ventre, ce comportement en dit plus que tu ne le crois.

01:55:05Lorsque Fido le fait devant toi, son maître, il se met dans une position très vulnérable.

01:55:10En faisant cela, il dit qu'il te fait confiance.

01:55:13Mais quand un chien le fait pour un étranger ou un chien inconnu, c'est un acte de soumission.

01:55:18En gros, il te dit qu'il ne sera pas une menace.

01:55:21De cette façon, le chien essaie d'éviter la confrontation.

01:55:25En tant que propriétaire d'un animal de compagnie, tu seras en mesure de comprendre le langage corporel de ton chien.

01:55:30Cela t'aidera à déterminer si un étranger peut s'approcher en toute sécurité

01:55:34ou si ton chien préfère rester seul.

01:55:37La queue de ton chien est un signe révélateur.

01:55:40Si ton animal tient sa queue dans une position naturelle, par exemple près de ses pattes, il est détendu.

01:55:46Si la queue est levée et remue, ce n'est pas nécessairement un signe de bonheur.

01:55:50Cela signifie plutôt que ton chien est excité par quelque chose.

01:55:54Une queue qui remue et qui se tient un peu plus en arrière indique une curiosité prudente.

01:55:59Le chien est intéressé par quelque chose, mais n'est pas encore sûr que c'est sans danger.

01:56:04Et une queue serrée entre ses pattes, c'est souvent un signe que ton chien est effrayé ou nerveux.

01:56:10Il est préférable d'éloigner ton animal d'une situation potentiellement mauvaise afin qu'il ne se sente pas menacé.

01:56:16Un grand mouvement de la queue, souvent accompagné d'un remuement du corps, est le signe d'un animal heureux.

01:56:22Mon chien bouge et aboie parfois dans son sommeil. Les chiens rêvent-ils?

01:56:26Tout comme les humains, les chiens entrent dans une phase de sommeil appelée REM, ou sommeil paradoxal.

01:56:32C'est le moment où l'on pense que les gens rêvent. Pendant la phase REM, ton esprit traite les événements de la journée.

01:56:38Il en va probablement de même pour ton animal.

01:56:40Ainsi, lorsque tu vois les pattes de ton chien bouger comme s'il était en train de courir, c'est probablement ce qu'il fait en effet dans son rêve.

01:56:47Et comme tu occupes une place importante dans sa vie, il est probable qu'il rêve même de toi.
