00:00:00 I have some great news for you, rats are ticklish, at least that was news for me.
00:00:07 Anyway, they have what we call a "laughter center" in their middle brain,
00:00:12 and they activate when someone tickles their animals or when they go to fun and playful activities.
00:00:18 Researchers discovered this in 2016 after tickling the stomach of rodents and listening to their little high squeaks.
00:00:26 Calibras are the only birds we knew that could fly backwards.
00:00:31 They do it mainly when they want to get away from the flowers.
00:00:34 And here is an animal that is unable to retreat, the kangaroo.
00:00:38 They can jump and travel long distances,
00:00:41 but the structure of their powerful hind legs and their large tails prevents them from walking backwards.
00:00:46 Narwhals are these strange creatures that look like some kind of sea unicorns.
00:00:53 This horn on their head is not a defense,
00:00:57 it is a huge tooth that comes out through the upper lip of the male narwhals.
00:01:01 This tooth probably plays a role in their nuptial parade.
00:01:05 Pink flamingos are not really pink, they are born gray.
00:01:09 But during their life, they eat a lot of algae and other foods containing a red-orange pigment that we know as beta-carotene.
00:01:17 This pigment is decomposed and ends up in their skin and feathers,
00:01:22 which makes them pink.
00:01:24 They must eat a lot of these foods to stay that way.
00:01:27 If we humans wanted to change the color of our skin,
00:01:31 we would not be able to eat enough rich beta-carotene foods to become really pink,
00:01:36 or, in our case, completely orange.
00:01:40 The lazy ones are really slow, all the jokes and references to their subject are true.
00:01:48 But they are also very skilled swimmers, and they move in the water 3 to 4 times faster than on land.
00:01:55 They can do the breaststroke just like humans.
00:01:57 And it's an important skill for them, because they are tropical animals, mainly living in the jungle.
00:02:03 And these areas are often flooded.
00:02:05 Tigers are the largest members of the feline family.
00:02:08 And yes, even bigger than lions.
00:02:11 Then, no tiger has the same stripes.
00:02:14 Their fur is actually a camouflage, which is useful when they need to find the ideal spot where their prey will not see them.
00:02:22 It is interesting to note that their skin is also striped, not just their fur.
00:02:27 And their stripes are as unique as our fingerprints.
00:02:31 Even if they look rather innocent and funny, you would not want to disturb a rhino.
00:02:38 These wild animals are part of the few species of mammals capable of poisoning you.
00:02:43 They have ergot on the ends of their hind legs that can release venom.
00:02:48 They are not societs, powerful enough to be deadly, but it still can be very painful and cause a lot of trouble as well as other problems.
00:02:56 When a coccinella has to defend itself against any predators, it starts by bleeding its knees.
00:03:02 It is not real blood coming out of its joints.
00:03:05 It is a particular chemical substance that smells very bad and, therefore, repels predators.
00:03:12 They have another mechanism that helps them survive in the pitiful animal kingdom, their specific color.
00:03:18 Predators do not really like vivid color combinations such as red, orange and black,
00:03:24 because they know that colored creatures in this way can have an awful taste.
00:03:28 Cockatoos can be extremely noisy in the morning, but they do not become deaf,
00:03:35 because they do not even hear how loud their cries can be.
00:03:39 What protects them are some kind of integrated ski balls.
00:03:43 Hens have a similar system that reduces the risk of hearing loss.
00:03:47 Not only do they have this protection, but they can also repel their cochlear cells if they are damaged in just a few days.
00:03:56 Hibou do not really have eye globes, they have something that looks more like eye tubes.
00:04:02 And they can't move them from left to right as we can do with our eyes.
00:04:07 This is why these birds have incredibly flexible necks.
00:04:11 They are able to turn their heads at 270 degrees.
00:04:14 In comparison, humans can only turn theirs at 180.
00:04:18 This is why hibou have a specific system of blood vessels in their heads.
00:04:23 It brings fresh blood to the brain if a bird turns its head too quickly and cuts its circulation.
00:04:32 Swim straight ahead. You may remember the way Dory, the blue surgeon fish, sang it in Nemo's world.
00:04:41 Dory was not a shark, but it is a message that some species of sharks must take to the letter.
00:04:48 The small sharks, the big white sharks, the baleen sharks and other species of fish continue to swim all the time.
00:04:56 Otherwise, they stop breathing.
00:04:59 We use our lungs to breathe.
00:05:03 And some sharks use a method called "buccal pump".
00:05:08 This means that they swim with their mouths open.
00:05:11 This way, they allow water to flow through their gills and thus extract oxygen.
00:05:18 The most dangerous animal on our planet is not a bear, a shark or a tiger with sharp teeth.
00:05:24 It is something much smaller. The mosquito.
00:05:29 Not only is it extremely irritating, but it also transmits serious diseases such as yellow fever, malaria or dengue.
00:05:37 Every year, hundreds of thousands of people are killed by such diseases.
00:05:42 Mosquitoes also outnumber all other creatures around the world, except termites and ants.
00:05:52 Grizzlies are incredibly strong animals with a powerful bite capable of crushing a bowling ball.
00:05:59 This is why they are not allowed in the bowling alleys.
00:06:04 Despite this, they are essentially small eaters.
00:06:07 They are strong enough to make their meal everything they encounter, including a bison, a moose or a caribou.
00:06:14 But they always like to nibble on their fruit, nuts and other berries, or even a little unlucky mouse that would get lost in the predator's mouth.
00:06:23 The desert taipan is the most venomous snake on the planet.
00:06:27 We also know it as "Doxuranus microlepidotus".
00:06:31 It lives in Australia.
00:06:33 A single secret bite is enough venom to prove fatal to at least a hundred adult humans.
00:06:39 And half an hour is enough if you have nothing to treat the bite immediately.
00:06:43 It is said that these snakes are most often shy and prefer to worry about their own business.
00:06:48 But like other animals, they will attack if they feel threatened or provoked.
00:06:53 There is a type of turtle that can stay alive for months under the ice breathing through its behind.
00:07:01 When it gets colder, some animals can't find a safe place to stay.
00:07:06 They must therefore survive in harsh winter conditions wherever they are.
00:07:10 And while bees are comfortable in their nests and the owls sleep in caves,
00:07:15 the painted turtles have no choice but to stay in their frozen tanks.
00:07:19 As the ice limits their access to the air, they directly extract the oxygen from the water and breathe through their behind.
00:07:26 Yes, I admit that it would be very practical.
00:07:29 It is well known that crows are incredibly intelligent animals.
00:07:33 They excel in problem solving.
00:07:36 But it seems that they also have an impressive social intelligence.
00:07:40 They are very in tune with their feelings as well as with the emotions of their companions.
00:07:46 If a crow in the group feels moody, it is likely that it also attracts others.
00:07:51 A real joy.
00:07:54 When they see a bird that doesn't like certain foods and expresses it very vividly,
00:07:59 they also lose all interest in their own food.
00:08:05 The pistol shrimp is one of the noisiest animals in the world,
00:08:09 even if it is tiny.
00:08:11 Only one goes from 1,900 meters long.
00:08:14 When it detects a prey, it opens its big claw,
00:08:17 which can reach up to half the length of its own body and let it go in a little bit of water.
00:08:23 Then it closes its mouth very quickly,
00:08:26 which produces an extremely powerful ball jet,
00:08:29 about 100 km / h.
00:08:31 These balls can stun or even finish the prey that the shrimp is trying to catch.
00:08:36 And when the balls explode, they produce an amazingly strong detonation of more than 210 decibels.
00:08:43 Crocodiles are even more frightening than we thought,
00:08:46 because many of them can gallop like goats.
00:08:50 They probably inherited this ability from their ancient crocodile-morph ancestors,
00:08:55 who were as clumsy as cats,
00:08:57 had long legs and could run at a speed of about 18 km / h.
00:09:03 The smallest crocodiles gallop most often when something pursues them.
00:09:08 But the caimans and alligators obviously do not need to use this skill.
00:09:13 It is you who are most likely to take your legs at your neck when you see them.
00:09:18 If an aggressive-looking dog approaches you,
00:09:21 do not hesitate to scream as loud as possible.
00:09:24 This will establish your dominance and frighten the animal.
00:09:28 Yes, it is a widespread myth.
00:09:30 And no, it won't help you if you meet a dog that seems to want to attack you.
00:09:35 The best solution in this rather frightening situation is to remain still
00:09:39 and avoid any direct visual contact with the animal.
00:09:42 You should not run, it could only encourage the dog to chase you.
00:09:47 And if the animal attacks, fall to the ground and roll into balls,
00:09:51 protecting your head and neck with your hands.
00:09:55 But what if you come across another much more dangerous representative of the canidae family,
00:09:59 like a wolf?
00:10:01 The flight will not save you.
00:10:03 Wolves are much faster than humans, especially in the forest.
00:10:08 In addition, as soon as you start running,
00:10:11 the instinct of the wolf hunter wakes up immediately.
00:10:14 Instead, maintain visual contact with the animal at all times
00:10:18 and never turn your back to it.
00:10:21 When trying to flee, make sure the wolf stays in front of you.
00:10:25 If the predator ends up behind you, his instincts will push him to attack.
00:10:29 So, move back slowly while facing the animal.
00:10:33 You may have heard that if you have been bitten by a snake,
00:10:39 you should apply garlic to the bite area.
00:10:42 Another well-received idea.
00:10:44 Garlic has absolutely no effect on snake venom.
00:10:47 Instead, try to remember the color and shape of the snake.
00:10:51 This can help doctors treat the bite and determine which antivenin is necessary.
00:10:56 In addition, try to remain as still and calm as possible.
00:11:00 This can slow down the spread of the venom.
00:11:03 And of course, immediately request medical help.
00:11:07 If you see a bear falling to the ground and pretending to be dead,
00:11:11 unfortunately, it does not always work that way.
00:11:15 First of all, you have to show the animal that you are not a prey.
00:11:19 Do not make loud noises and do not scream.
00:11:22 Because this way, you could even more annoy the plantigrade.
00:11:26 If you shake your arms, do it slowly.
00:11:29 If you choose to calm the bear, do it in a low and calm voice.
00:11:34 Without turning away from the animal's eyes, start moving sideways.
00:11:38 This will prevent you from tripping and falling.
00:11:42 Do not rush and do not run away either.
00:11:45 Although at first glance, bears may seem heavy and clumsy,
00:11:49 they are surprisingly good sprinters.
00:11:51 In addition, these animals like to track their prey.
00:11:54 That's why, if a bear is charging you, stop moving.
00:11:58 There is a widespread idea that bees could only sting once.
00:12:05 But in reality, the problem is that the dart of bees is beveled
00:12:09 and can easily get stuck in the skin of their victims.
00:12:12 The dart remains stuck, the bee cannot free itself
00:12:15 and generally does not survive such a hook.
00:12:18 You must remember that bees will protect their hive whatever happens.
00:12:22 And they can sting you even if you just pass by.
00:12:26 Dark colors can make bees more aggressive,
00:12:29 because these shades make people look like their natural enemies.
00:12:33 That's why if you're wearing a black t-shirt,
00:12:36 your chances of being stung by these insects are higher.
00:12:40 If a swarm of bees is chasing you, hide in a dark or closed place.
00:12:44 The lack of light should divert these insects from your path.
00:12:48 Similar rules apply to encounters with geese.
00:12:52 One of the worst mistakes you can make is to have your long hair detached
00:12:56 and to wear dark clothes.
00:12:58 Geese are attracted to dark objects in motion.
00:13:01 And your clothes, as well as your hair, perfectly respond to this description.
00:13:05 So, if you suspect that you could stumble upon geese,
00:13:08 wear light colored clothes and tie your hair in a horse or chignon tail.
00:13:13 Contrary to popular belief,
00:13:15 bathing a geese in vinegar or baking soda is useless.
00:13:19 Instead, apply ice on the affected area.
00:13:23 Gorillas are nicknamed "kings of the jungle".
00:13:27 And it's not without reason.
00:13:29 They are dominating animals that tend to protect their families and their territory.
00:13:33 They will not attack you if you behave politely.
00:13:36 So, when you meet a gorilla, sit down.
00:13:40 This way, you won't look big and threatening by overshadowing the animal.
00:13:44 Try not to make loud noises and avoid direct visual contact.
00:13:48 In case of attack or approach, roll in a ball.
00:13:51 Gorillas are proud creatures.
00:13:54 And, as a rule, they do not attack the weak and the defenseless.
00:14:00 Surprisingly, a wild kangaroo can also be a serious threat to humans.
00:14:05 But it will only happen if you enter the animal's territory and it feels threatened.
00:14:10 To avoid conflict, everything is, and it's not a joke.
00:14:14 Your everything must be brief and discreet.
00:14:16 The kangaroo will consider it as a sign that you are sick.
00:14:19 And there is a chance that it won't attack you.
00:14:22 After that, move back slowly.
00:14:24 This way, you will look smaller, so less threatening.
00:14:28 Don't turn around and don't run either.
00:14:30 This will only provoke the animal.
00:14:32 Remember that kangaroos are excellent jumpers, able to catch you in a few moments.
00:14:37 And of course, we must talk about sharks.
00:14:40 The good news is that out of several hundred species of sharks on Earth,
00:14:44 only about a dozen are taken by humans.
00:14:47 But if a shark is interested in you, it will be extremely difficult to escape.
00:14:52 To avoid attracting sharks, avoid that blood or other bodily fluids are in the water.
00:14:57 Sharks can smell it from a great distance.
00:15:00 In addition, when you go swimming, remove your shiny jewelry or other reflective accessories.
00:15:06 Sharks are attracted by things that shine, because they confuse them with the scales of fish.
00:15:12 Don't turn your back to this predator.
00:15:14 And don't try to run away in panic.
00:15:17 You would only look like a prey in this way.
00:15:20 Move slowly.
00:15:22 Hitting the animal in the eyes or the gills can only make it angrier and make it more determined to attack.
00:15:28 Instead, try to make balls.
00:15:30 They are too noisy for sharks, and these animals don't like them at all.
00:15:35 If you meet a wild boar, it would be a mistake to try to escape by jumping into the water.
00:15:41 It turns out that boars are good swimmers, who can easily chase you if they feel threatened.
00:15:47 Instead, start whistling or singing if you see a wild boar walking not far from you.
00:15:54 If you come face to face with a lion, keep a visual contact with the animal.
00:16:01 Don't turn your back and don't turn your eyes away.
00:16:04 It would give the predator time to attack.
00:16:06 Try to look more imposing than you really are.
00:16:09 Raise your arms and shake your jacket.
00:16:12 If you look big and threatening, the animal will try to avoid confrontation.
00:16:17 Talk to the lion in a reasonably loud and confident voice.
00:16:21 This behavior is not typical of a victim.
00:16:24 You will disconcert the predator and he will perceive you as an annoying presence that is better avoided.
00:16:31 Elephants are smart and rather friendly animals, but they are also known to attack people.
00:16:37 It is particularly true for elephants accompanied by their young.
00:16:41 If you come face to face with an elephant, pay attention to its body language.
00:16:46 If its trunk is curled up and its ears are thrown back, it means it could try to attack you and crush you.
00:16:53 If the animal approaches, don't run.
00:16:55 Try to find something that can serve as a barrier between you and the elephant.
00:16:59 It can be a rock or a tree.
00:17:02 Rhinoceros have a bad eye, which is why it is easy to scare them and push them to attack.
00:17:09 These animals can reach 60 km/h, and it is really difficult to escape them.
00:17:15 The most effective way to escape a rhinoceros is to hide behind a tree.
00:17:20 It is a serious obstacle for the animal.
00:17:23 It is also unlikely that it will chase you through bushes or tall grass.
00:17:28 Hippos can sometimes look cute, but this image is misleading.
00:17:36 These pachyderms can be extremely dangerous.
00:17:39 Despite their weight, hippos can run at a speed of 30 to 45 km/h.
00:17:45 In addition, it is quite easy to annoy them.
00:17:47 So if the weather is particularly hot, try not to approach bushes.
00:17:52 The water level drops during the dry season, and hippos hide in tall grass.
00:17:57 For the animal to leave you alone, climb a tree, a rock or a steep hill,
00:18:03 and wait there until it leaves.
00:18:06 Despite popular belief, hippos react to movement, and not to red or any other color.
00:18:13 This is why if a hippo runs towards you, stay straight and still.
00:18:17 Use your cap, your t-shirt or any other clothing you have at hand as a guide.
00:18:23 When the hippo is close enough, throw this accessory as far away from you as possible.
00:18:29 The hippo will change its trajectory and will pursue this new target.
00:18:33 It's just an ordinary day.
00:18:36 As usual, you take a shower before starting to prepare for work.
00:18:40 Everything goes as planned, until everything goes to shit.
00:18:45 A clumsy gesture, a little water spilled on the ground, and here you are fighting with your arms in the air,
00:18:51 your body approaching the ground at a frightening speed.
00:18:55 Everything turns black.
00:18:58 The first thing you hear is a loud whistle in your head.
00:19:02 "Ouch, your head, ouch!"
00:19:05 You get up with caution. There is no blood, and that's even better.
00:19:10 What is even better is that the annoying noise stops abruptly.
00:19:14 Holding your head, you leave the bathroom and miss to stumble on your cat Milo.
00:19:20 He meows, then a clear voice in your head tells you, "You big clumsy!"
00:19:25 "Huh?" You turn your head with fear, but you see no one.
00:19:29 There is only you and… Milo?
00:19:32 You probably hit your head harder than you thought.
00:19:35 You raise your shoulders and head to the kitchen.
00:19:38 Milo follows you. You hear incessant snoring.
00:19:41 "Why can he sleep in the bedroom when I'm not allowed to stay?"
00:19:46 "Why haven't I had my meal yet? This human is too lazy.
00:19:50 Should I scratch the sofa or leave a mouse on his pillow?"
00:19:53 The first thought that comes to mind is, "Are there mice in the house?"
00:19:58 The second is more relevant.
00:20:00 "I'm losing the ball. Great!"
00:20:03 In automatic driving mode, you pour a little milk into Milo's bowl
00:20:07 and fill another one with croquettes.
00:20:10 The cat doesn't seem to be satisfied with your speed, if we believe his…
00:20:14 "Oh, for heaven's sake, move, man!"
00:20:18 OK, now you have to live with the fact that your beloved cat Milo
00:20:23 is actually the character of a grumpy old man.
00:20:26 "Argh!"
00:20:27 You decide to lock yourself in the bathroom again because you start to feel exhausted.
00:20:32 You sit down heavily on the toilet seat and you miss falling from your throne upside down
00:20:37 when you hear the sounds of noisy arguments.
00:20:41 After looking around you, you discover that apparently
00:20:44 there are not only mice but also cockroaches in your house.
00:20:48 Simply brilliant!
00:20:50 You are currently looking at a pair of insects that seem to be fighting.
00:20:55 At least one of them accuses the other of…
00:20:57 Wait, what? Cheating?
00:21:00 You've heard enough.
00:21:02 You're about to leave the bathroom when you hear a "Bang!"
00:21:06 In the bathroom, you find your cat lying on the floor under a broken flower pot.
00:21:10 The worst part is that he looks really hurt.
00:21:13 He keeps meowing and meowing.
00:21:15 "I'm hurt, I'm hurt, my leg, ouch, ouch!"
00:21:19 "But the sofa can't stay without scratches today!"
00:21:23 You catch Milo, push him into his car,
00:21:26 "Hey, watch out, you, biped!"
00:21:28 and you head to the clinic.
00:21:30 On the way, you have to focus hard to block the noise of the countless voices that are attacking you.
00:21:36 The vet's waiting room is full.
00:21:38 You'll have to wait a long time.
00:21:40 Half an hour later, your head is ready to explode.
00:21:44 You discover that this yellow python is suspiciously interested in the hamster
00:21:50 that the young girl in the corner is holding against her chest.
00:21:54 "So, so pretty!"
00:21:58 The hamster is worried about its reserve of nuts.
00:22:01 "Where did I hide them? Where, where, where?"
00:22:04 A little dog with an old lady is afraid of needles.
00:22:08 "If this pointy thing comes near me again, they'll regret it!
00:22:12 I'll destroy everyone on my way!"
00:22:15 Your turn has finally come.
00:22:17 The vet invites you to her office and you lean to get Milo
00:22:21 when a desperate young man makes a noise in the room.
00:22:25 "My hamster, what's wrong with him?"
00:22:27 The vet looks at you apologizing, but you are focused on the hamster.
00:22:32 He looks weak, but you manage to understand the words "chocolate", "yum".
00:22:37 When you tell the vet and the anxious owner that the hamster ate chocolate,
00:22:42 which is actually a poison for dogs,
00:22:44 they look at you with a funny look and disappear into the doctor's office.
00:22:48 Some time later, the guy comes out holding the dog, who looks much better than before.
00:22:53 When they left, the vet turns to you.
00:22:56 "How did you know that this dog had eaten chocolate?"
00:22:59 "Oh oh, here we are!"
00:23:01 You decide that honesty is the best strategy
00:23:04 and you tell the vet that you can understand what the animals say.
00:23:08 Of course, she doesn't believe you.
00:23:11 You have to make an effort to persuade her,
00:23:15 but with the help of two other dogs, Milo and an old squirrel,
00:23:19 you manage to make her believe what you are saying.
00:23:22 When you get home, you have a dizzy head and you are very hungry.
00:23:27 You only think of flat eggs and bacon.
00:23:30 "Yum!"
00:23:32 "Wait, bacon? But it's..."
00:23:35 "Oh oh, apparently, from today on, you have become a vegetarian!"
00:23:40 Anyway, that's when everything changes.
00:23:44 You don't know how it happened, but you become famous overnight.
00:23:49 The next morning, a loud noise wakes you up,
00:23:52 and it's not like animals were talking to you.
00:23:55 You look out the window and you see a crowd of people gathered around your house.
00:24:00 Some are journalists, but others are owners of pets who have come to ask for help.
00:24:06 Milo is not happy.
00:24:10 While groaning non-stop and calling you by all the names,
00:24:13 he bites your leg and takes refuge under the stairs.
00:24:16 And you, you go out to talk to people and answer questions from journalists.
00:24:22 In the evening, you are exhausted, but also happy.
00:24:27 You saved several animals today.
00:24:30 They had serious health problems and psychological disorders
00:24:33 that their owner could not solve alone.
00:24:36 Lying in your bed in the dark,
00:24:38 you think about how you could use your powers.
00:24:42 That's when your plan takes shape.
00:24:45 Soon, you become the world's most renowned pet care specialist.
00:24:50 You listen to the animals talk about their problems,
00:24:53 you relieve them of their depression,
00:24:55 and you help them to resolve their misunderstandings with their owner.
00:24:58 TV shows invite you for interviews,
00:25:01 your YouTube channel is growing every day,
00:25:04 people recognize you in the street and ask you to take pictures with them.
00:25:08 You travel the world,
00:25:10 you help endangered species and give lectures.
00:25:13 You open veterinary clinics all over the world
00:25:16 and you invite the best professionals to work there.
00:25:19 You never feel alone.
00:25:22 There is always someone to talk to or listen to.
00:25:25 At least a few birds when you walk in the park,
00:25:28 or a few fish when you have a rare moment of rest on the beach.
00:25:32 At the same time, you have become aware of the number of animals
00:25:35 begging for help, but no one can hear them.
00:25:39 You then decide to take on the role of their spokesperson.
00:25:43 It turns out that you are now famous not only in the world of humans,
00:25:47 but also in that of animals.
00:25:49 They are grateful and, in return, they begin to inform you
00:25:52 of various natural disasters that are about to occur on the planet.
00:25:57 You have heard that animals can predict earthquakes or volcanic eruptions.
00:26:03 And if before people had to make efforts to notice the unusual behavior of certain species,
00:26:08 now animals simply pass you information on what is going to happen and where.
00:26:15 With time, you notice that you spend less time among people and more time with animals.
00:26:20 Together, you plan campaigns against zoos,
00:26:23 circuses and other places where animals are held against their will.
00:26:27 And then one day, the unthinkable happens.
00:26:31 You go home when a black truck stops next to you.
00:26:35 Several masked guys catch you and push you inside.
00:26:38 The doors close behind you.
00:26:41 Inside, you discover that several influential people are not happy with your activity.
00:26:47 You realize that this trip is not going to end well.
00:26:51 The guys blindfold you and drive you somewhere.
00:26:54 But at one point, you lose your footing and hit your head against something.
00:26:59 Very hard!
00:27:00 You open your eyes.
00:27:01 Milo stands above you and looks at your extended body with a certain indifference.
00:27:07 And then the most terrible thing happens.
00:27:10 He meows, which looks like a whole sentence, turns around and leaves the bathroom.
00:27:16 And you don't understand a single meowing of what he says.
00:27:20 Was it all just a dream?
00:27:22 Did you know that animals saw the world differently from us?
00:27:26 Let's take this as an example.
00:27:28 Pigeons actually have a better view than humans.
00:27:30 It's crazy, isn't it?
00:27:31 So let's try to see the world through the eyes of some animals.
00:27:35 Let's start with snakes.
00:27:36 Their way of seeing the world is totally different from ours.
00:27:39 They have special infrared-sensitive receptors in their museums.
00:27:43 This allows them to perceive the heat emitted by the mammals in their heat.
00:27:47 Now let's move on to cows.
00:27:48 These big gullies don't see colors as well as humans.
00:27:51 They are unable to perceive red, because they don't have the necessary receptors in their retina.
00:27:57 So they only perceive variations of blue and green.
00:28:00 In addition, they don't like it when someone approaches them from behind.
00:28:03 Their vision is almost panoramic and the only area they can't see directly is the back of their head.
00:28:09 So if you ever sneak behind a cow, make sure you get noticed.
00:28:14 Horses have a blind spot right in front of their face, because of the position of their eyes.
00:28:19 This means they can't see things directly in front of them.
00:28:22 In addition, they don't perceive as many colors as we do.
00:28:25 Just like cows, their world is mainly composed of green, yellow and blue.
00:28:29 Poor animals.
00:28:30 Fish have ultraviolet receptors and lenses that are more rounded than ours.
00:28:35 This gives them a vision of almost 360 degrees.
00:28:38 As for colors, they can see the same as we do.
00:28:42 But since light behaves differently underwater, they have trouble distinguishing red and its shades.
00:28:47 Deep-sea fish can easily see in the dark, which is extremely useful.
00:28:52 Sharks, on the other hand, cannot distinguish colors at all, but they see much more clearly underwater than we do.
00:28:58 Birds have quite unique ways of seeing the world.
00:29:01 Unlike humans, they can distinguish ultraviolet light.
00:29:05 This helps them to differentiate males and females from their own species, as well as to better locate themselves in their environment.
00:29:11 In addition, they are very good at focusing.
00:29:13 So hawks and eagles can focus on a little mouse in a field up to a distance of more than 1 km.
00:29:20 A pigeon can perceive all kinds of small details.
00:29:23 So if you ever need to spot a crack in the sidewalk, just ask a pigeon.
00:29:27 And by the way, they have a field of vision of 340 degrees.
00:29:30 And in general, their sight is considered to be twice as sharp as that of humans.
00:29:35 And there you go, I'm jealous of a pigeon.
00:29:37 Insects also have quite strange patterns of perception.
00:29:40 Flies, for example, have thousands of small eye receptors that work together to give them a global view of what's going on around them.
00:29:48 And guess what? They can see everything in slow motion.
00:29:51 In addition, they can also see ultraviolet light, which helps them communicate.
00:29:55 Bees have their own problem.
00:29:57 These little creatures are unable to recognize red.
00:30:01 For them, it just looks like dark blue.
00:30:03 It's crazy, isn't it?
00:30:04 Let's move on to rats.
00:30:05 These little guys can't see red either, but that's not the strangest part.
00:30:09 Each of their eyes moves independently, so that they see double all the time.
00:30:13 It's amazing that they don't bump into each other more often against the walls, right?
00:30:17 Cats don't perceive the shades of red or green, but they distinguish brown, yellow and blue hues like pros.
00:30:24 In addition, they have a wide-angle vision, so that they have a better peripheral vision than ours.
00:30:29 And there's more.
00:30:30 When it's completely dark outside, cats turn into ninjas and see up to six times better than us.
00:30:36 Their pupils adapt to any light as if by magic.
00:30:39 Now, let's talk a little about dogs.
00:30:41 Our furry companions can't see red or orange, but they excel in blue and purple.
00:30:46 In addition, they can differentiate up to 40 shades of gray.
00:30:50 Well, it's not 50, but it's still impressive.
00:30:52 On their side, frogs are really difficult in terms of food.
00:30:56 They don't get bored with immobile prey.
00:30:58 They could be surrounded by a buffet of delicious insects.
00:31:01 But if all that doesn't move, the frogs won't even care.
00:31:04 And they're not the finest observers either.
00:31:07 If something seems uninteresting to them, like a shadow for example, they won't even bother looking.
00:31:13 Chameleons have eyes that can move independently from each other.
00:31:16 So they can see everything around them without even turning their heads.
00:31:20 They are even able to see two images at the same time, like watching two different movies side by side.
00:31:25 Pretty badass, right?
00:31:26 And you, what would you do if you suddenly had a 360-degree vision like a chameleon?
00:31:31 Share your opinion in the comments.
00:31:33 Well, let's be realistic.
00:31:35 We, humans, are pretty ordinary.
00:31:39 We are not superheroes with superpowers, are we?
00:31:43 What?
00:31:44 You didn't know?
00:31:46 The animal world, on the other hand, has a bunch of superheroes.
00:31:51 Some creatures go and fly forever, others seem to be making fun of gravity laws.
00:31:56 Others are still immune to venom, and others can finally run on water.
00:32:02 Some of them will give you chills.
00:32:05 The first superpower on the list is the ability to live without water.
00:32:09 Kangaroo rats can run out of water for years.
00:32:12 In fact, it doesn't bother them to live without water.
00:32:15 Humans, on the other hand, can only survive three days without water.
00:32:19 Human, 0, kangaroo rat, 1.
00:32:23 These little animals live in extremely arid desert areas,
00:32:27 and must draw water from the seeds and plants they eat.
00:32:31 Although this may seem a little worrying, kangaroo rats also know how to extract water from their urine before going to the bathroom.
00:32:38 So they don't lose a single drop of this precious moisture.
00:32:42 This could prove useful in sports.
00:32:45 Let me now introduce you to the Peter Parker of the animal world.
00:32:49 Absolutely.
00:32:50 It looks like Spiderman is real, but he's not human.
00:32:53 Here is a gecko lizard, or more simply a gecko.
00:32:56 This creature has the wonderful ability to climb on all kinds of vertical surfaces, and can even walk on the ceiling.
00:33:03 This feat that defies the laws of gravity is possible thanks to the unique plantar cushion of the lizard, covered with tiny hairs.
00:33:11 They can cling to almost any surface, whether it's smooth, hard, rough or soft.
00:33:18 Another funny fact about these lizards is that they don't have eyelids.
00:33:22 So they always keep a wide open eye on what's going on around them.
00:33:27 If you're wondering how they protect their eyes, here's the answer.
00:33:32 Their eyes are covered with a transparent membrane, the cornea.
00:33:36 Of course, they can't close their eyes, and if they have something in their eye, they just lick it.
00:33:42 It's true, they clean their eyeballs by licking them.
00:33:46 You can imagine that this is another superpower.
00:33:49 Supersonic superpowers?
00:33:52 Yes, of course.
00:33:53 A 2.5 cm subtropical shrimp disorients its prey with a shock wave.
00:34:00 Despite its modest size, the pistol shrimp is one of the noisiest marine animals.
00:34:05 When the shrimp snaps its claws, it makes a noise as loud as a sonic boom.
00:34:11 Naturally, the sound stuns the prey, and the shrimp can catch it without much effort.
00:34:16 In the world of comics, there's venom.
00:34:19 In the animal world, there's a type that can be called anti-venom.
00:34:23 Opossums are known for their very practical trick, which is to pretend to be dead when a predator attacks them.
00:34:31 But that's not all.
00:34:32 These animals are also immune to snake venom and viper pelliades.
00:34:38 The secret lies in a peptide that helps opossums neutralize dangerous chemical substances.
00:34:44 That's why snakes are one of the favorite snacks of the opossum's diet.
00:34:50 Their diet also consists of a curious element, the ticks.
00:34:54 An opossum can catch about 5,000 ticks per season, and most of them are taken on their own body.
00:35:01 Imagine a fish so famous that it's called a dangerous fish.
00:35:06 It's the mbenga, which literally translates to "dangerous fish" in Swahili.
00:35:11 This monster lives in fresh water and doesn't hesitate to eat a crocodile.
00:35:15 Not an entire crocodile, but the mbenga can easily take a bite.
00:35:21 Finally, to be honest, mbengas are afraid of crocodiles, just like crocodiles are afraid of mbengas.
00:35:27 You're watching this video with a mbenga, aren't you?
00:35:31 Well, all the gadgets we own, we owe them to electric mbengas in a way.
00:35:36 All gadgets have batteries, and mbengas have contributed a lot to the invention of an electric battery in 1800.
00:35:43 I know, I know, batteries have changed in an unrecognizable way since then.
00:35:48 But still, the first electric battery was invented thanks to electric mbengas.
00:35:54 Anyway, if you see one and you want to thank it for its magnificent invention, avoid doing it.
00:36:01 The problem is that they can deliver shocks up to 860 volts.
00:36:06 You don't want to experience it.
00:36:09 Let's talk about the Dracula tale of the animal kingdom.
00:36:12 No, I'm not talking about bats.
00:36:14 I'm talking about the vampire fish Akrok.
00:36:17 These fish are known as payara and have long tails that exceed their lower jaws.
00:36:22 That's why some people associate them with vampires.
00:36:26 Hippos are the gurus of beauty, since they know how to save a fortune on skin care.
00:36:33 Living under the harsh African sun, these secret animals have a red oily substance that looks like sweat that evaporates and keeps the body of the animals cool.
00:36:44 In addition, this liquid serves as both moisturizing cream, sunscreen and antibiotics, but they are not the only ones to have such a superpower.
00:36:53 Shrimp also know how to produce a natural sunscreen, but they use it to protect their eyes.
00:37:01 These are amino acid pigments.
00:37:04 And these pigments act like special filters that also contribute to the clarity of their vision.
00:37:10 This is what I call multitasking.
00:37:13 Hurricanes have dark spots around their eyes, which makes them even cuter.
00:37:18 But these black circles are not there just to make our friends even more adorable.
00:37:23 They also act as integrated sunglasses.
00:37:27 The dark fur of the spots blocks the burning sun, allowing the hurricanes to look directly at the sky.
00:37:34 In addition, thanks to this, the sentinel, a surrogate that watches birds and other predators, can easily see the danger and alert its companions.
00:37:46 Wild goats are famous for their climbing skills, but it is the Alps' bouquetin, in northern Italy, which is the champion.
00:37:54 This animal can climb almost all vertical surfaces, thus defying several laws of physics.
00:38:00 It is interesting to note that the animals that walk on the walls of the steepest cliffs are generally sea goats, accompanied by their young.
00:38:08 The big males prefer to keep their distance and use flat horizontal surfaces.
00:38:14 They are clever.
00:38:16 Salmons are skilled navigators who could make most drivers blush with shame.
00:38:21 However, this competition would not be fair.
00:38:24 After all, salmon can feel the magnetic field of the planet and use it to navigate if they get lost.
00:38:31 If you have trouble navigating in the city, a salmon could help you.
00:38:36 Do not forget to tie the aquarium.
00:38:39 Some animals protect themselves with venom or vile bites, while others use chemical tricks to protect themselves.
00:38:48 Listen to this. Some species of millipedes produce hydrogen cyanide and exudate when they feel threatened.
00:38:57 Hydrogen cyanide is inodorous, but very toxic.
00:39:00 A single small millipede cannot seriously injure you, but you risk burns or even clots if your skin is sensitive.
00:39:08 In addition, to make the picture even more frightening, some millipedes shine in the dark.
00:39:14 So be careful. And if you see a bright spot at night, save yourself as soon as possible.
00:39:22 When the millipede feels threatened, it sprays a burning liquid from the end of its abdomen, emitting a dry noise.
00:39:30 As soon as the lepidopterus feels a danger, a chemical reaction occurs in special tanks located in its abdomen.
00:39:37 The heat released by this process reaches almost boiling point and also produces a special gas that triggers ejection.
00:39:44 This super protection is generally fatal for attacking insects. I imagine.
00:39:50 Jesus Christ lizards have the strange ability to run on water.
00:39:54 First of all, their hind legs are equipped with long toes, whose skin stripes can spread over the water.
00:40:01 Thus, a larger surface of the lizard's foot is in contact with the water. Then, when it runs on the water, its legs can enter at incredible speeds.
00:40:11 It creates small air pockets that impatient the animal disannoyer and the maintenance on the surface.
00:40:17 The chicks may not always be very interesting, but that does not make them less surprising.
00:40:22 These tiny animals can jump about 50 times the length of their body.
00:40:27 If people could do that, we would be able to jump approximately 1.5 km in the air.
00:40:33 Well, let's try.
00:40:35 The most curious thing about the amazing ability of the chicks is that they shoot most of the power of their jumps, their toes, and not their knees.
00:40:44 What is your favorite animal superpower?
00:40:46 I vote for the orangutan.
00:40:48 I don't like to queue to go to the bathroom.
00:40:54 You decided to dive underwater for the first time. The water is clear and the sun illuminates the seabed.
00:41:00 You take some selfies with the fish that pass by, when suddenly the ocean becomes dark as night.
00:41:07 You look up and, oh my God, what is this huge animal?
00:41:13 It's certainly not a shark, not more than a whale. Is it a turtle? Yes, but don't be afraid, it won't hurt you.
00:41:23 If you lived on this same land about 72 million years ago, then maybe it could have really happened to you.
00:41:31 Scientists have recently discovered the fossils of a huge sea turtle that could have reached up to 4 meters in length.
00:41:39 If you have no idea what that means, let's look at some examples.
00:41:44 It's the average length of a hippopotamus, six Golden Retrievers half-naked, or two Michael Jordans stacked on top of each other.
00:41:54 The scientific name of this turtle, the Leviathanocelis Aenigmatica, is a tribute to the legendary sea monster known as the Leviathan.
00:42:03 Maybe you remember from your mythology classes at school.
00:42:06 The Leviathan is supposed to be a mythical creature that would swallow entire ships or sailors considered too greedy by the creature.
00:42:14 Can you imagine being swallowed by this huge sea turtle? Me? I'll give it a go.
00:42:20 The fossils of this gigantic creature began to be excavated between 2016 and 2021 in northern Spain.
00:42:29 The first fossil was found by a hiker in the Spanish Pyrenees, and it was about 20 centimeters long.
00:42:37 The pool of this turtle alone was about 90 centimeters.
00:42:42 It would certainly be one of the biggest turtles today, if it hadn't gone extinct.
00:42:48 For your information, the largest living sea turtle today can reach up to 2 meters in length, which is already not bad.
00:42:58 And now, what would you say about a gigantic prehistoric scorpion?
00:43:03 I bet most people here are not big fans of these creatures, especially since they are venomous.
00:43:09 This is why the idea of ​​a 3-meter-long aquatic scorpion could be a nightmare for some.
00:43:15 Let's just say that if it hadn't disappeared about 400 million years ago, lakes and rivers would be much less bucolic places for humans today.
00:43:26 These gigantic arachnids were considered first-rate predators at the time, hunting everything from fish to other animals, including their own species.
00:43:35 Ouch, I have chicken skin just from imagining these monsters.
00:43:39 We should thank the asteroid that hit our planet now or later in the video.
00:43:44 Another prehistoric animal that would amaze humans if it were still alive is the famous Megatherium, a sloth of gigantic proportions.
00:43:54 It is thought that this huge sloth could have reached up to 6 meters in length, for a weight of nearly 3.6 million kilos.
00:44:02 These remains are found in the forests of the South American prairies.
00:44:07 The creature was used to sit on its back legs in order to reach the fins of the hot-spreaded thumb.
00:44:13 These giant sloths had long claws, which helped them climb trees.
00:44:18 I must admit, I am not very comfortable imagining these lazy-looking sloths climbing trees.
00:44:25 Oh, of course, some dinosaurs will be part of our list of oversized creatures, but before that, here's a funny fact.
00:44:32 Did you know that some dinosaurs are still alive today?
00:44:36 Researchers have determined that birds could be classified as theropods.
00:44:41 This creature is redoubtable as tells that the Tyrannosaurus and the Velociraptor are part of the Niantic group.
00:44:48 I'm sure you heard these names much earlier if you watched Jurassic Park.
00:44:53 The Velociraptor is this frightening dinosaur that intrudes into the kitchens.
00:44:57 Well, they evolved, gained some feathers, and turned into various species of birds that we know today.
00:45:04 This means that any bird, from dendon to mesange, is a direct descendant of dinosaurs.
00:45:11 Now, does the name Spinosaurus tell you something?
00:45:16 You can admire this huge dinosaur in some museums today.
00:45:20 It's fossil, I mean.
00:45:22 Spinosaurus was one of the largest terrestrial predators to have walked the earth.
00:45:27 Or rather, to have walked the earth and its waters.
00:45:30 Because researchers think that this dino was semi-aquatic.
00:45:34 It mainly fed on meat, which means that humans would be natural prey if they still lived today.
00:45:42 This carnivorous dinosaur lived about 90 to 100 million years ago.
00:45:46 It was about 18 meters long, 4 meters high, and weighed up to 22 tons.
00:45:52 Its head was about the size of 8 bowling balls, and had the shape of the face of a crocodile.
00:45:59 Basically, the Spinosaurus was a big elephant from Africa with a crocodile's mouth.
00:46:05 I'm kidding, but it would have looked funny, wouldn't it?
00:46:09 A much more attractive dinosaur was this one, the Patagotitan Mayorum.
00:46:14 It is considered the largest dinosaur that has ever lived on our planet.
00:46:18 What made it so big was its extremely long neck and its outstretched tail.
00:46:23 You wouldn't want to stand behind this creature, believe me.
00:46:28 If it decided to make a sudden move with its tail, you would be catapulted far away.
00:46:32 This dinosaur lived about 100 million years ago.
00:46:35 Its fossils were discovered for the first time in Argentina around 2012.
00:46:41 It was 36 meters long from head to tail, which made it almost as big as a football field in its width.
00:46:48 Did I mention that it weighed almost as much as a spaceship?
00:46:53 We're talking about 75 tons.
00:46:56 If it had been carnivorous, it would have probably been the biggest predator.
00:47:00 But this big guy was a peaceful herbivore.
00:47:03 It had such a long neck that it could chew the leaves of the tallest trees.
00:47:07 Cute, isn't it?
00:47:09 We also need to talk about the Chastasaurus.
00:47:13 As its name suggests, this lizard once populated the region of Mount Shasta in California.
00:47:19 Even if it was a marine reptile that probably never set foot on the mountain itself.
00:47:25 This dinosaur was generally 7 meters long.
00:47:29 But there was a specific variety of this species that could reach up to 21 meters.
00:47:34 The size of the Great Blue Whale.
00:47:37 Which makes it the largest marine reptile ever lived.
00:47:42 A funny fact about the Chastasaurus is that scientists think it had no teeth.
00:47:47 Which means it could only feed on prey with soft bodies, like squid, for example.
00:47:56 The next animal on our list is the Great Blue Whale.
00:48:00 Believe it or not, the largest living animal on Earth actually started small.
00:48:05 Nowadays, an average adult Great Blue Whale can reach up to 30 meters long and weigh up to 200 tons.
00:48:12 This is more than half the weight of the current elephants.
00:48:16 Or the 20,000 rhinos.
00:48:19 Or the 2,650 people of the average.
00:48:24 The Great Blue Whales have to consume up to 5-6 million calories a day to feed on this body.
00:48:31 Or that's just for information.
00:48:33 It's the equivalent of 30,000 Big Macs.
00:48:36 But the Great Blue Whales were not always that big.
00:48:40 They actually evolved from a four-legged mammal that roamed the Earth about 48 million years ago.
00:48:47 Their ancestor was called Pachycetus and was only 2 meters long.
00:48:51 Here's another funny fact.
00:48:53 To be able to live in water as it does today, the Great Blue Whale had to make an intense effort to adapt.
00:49:00 The Great Blue Whale can renew between 80 and 90% of the oxygen in its lungs every time it breathes.
00:49:07 In comparison, a human only renews up to 15%.
00:49:12 This allows these creatures to dive for up to an entire hour and reach a stunning depth of 100 meters.
00:49:21 Elephants were destined to be on this list.
00:49:24 African elephants are currently the largest terrestrial animals on our planet.
00:49:29 They can reach about 4 meters high and weigh up to 7 tons.
00:49:33 It's pretty small if you compare them to other animals that have lived on Earth before, isn't it?
00:49:39 But if you put a human about 1.80 meters next to an elephant, you can see that it's not that small.
00:49:45 African elephants are larger than their close relatives, Asian elephants, and they have a life expectancy similar to that of humans, up to 70 years.
00:49:54 Pokemon may have made us all wish one day that salamanders were real dragons.
00:50:00 Although this is not the case, they can still be fascinating.
00:50:05 There is a giant salamander species, which is known to be the largest living amphibian.
00:50:11 They can reach the size of an average human, or 1.80 meters.
00:50:16 I doubt it's a very pleasant underwater encounter.
00:50:20 I've prepared a test for you on animals.
00:50:23 I'm going to show you an image and you're going to have to tell me which animal it is.
00:50:27 Does it seem easy to you? We'll see.
00:50:30 Don't forget to write down your score and you'll find out your result at the end.
00:50:34 We're going to start with something easy and we'll go over things gradually.
00:50:38 Here's the first animal. What do you think it is?
00:50:42 Of course it's an elephant. Elephants are the largest terrestrial animals and their trunk is incredibly sensitive.
00:50:54 The Asian elephant can even pick up a peanut and bite it.
00:50:58 Here's the next one. What do you think?
00:51:03 It's definitely a turtle.
00:51:11 Did you know that it's not the DNA that determines the sex of newborns?
00:51:14 It's the temperature in the nest.
00:51:17 If it's cool, the newborns will be males. If it's hot, they will be females.
00:51:23 What is this adorable animal in your opinion?
00:51:28 It's a penguin. We offer flowers to our loved ones to show our affection and recognition.
00:51:38 But penguins are not only good at picking up pebbles,
00:51:41 they can also control the flow of blood in their feet, which prevents them from freezing.
00:51:46 This one is easy. What do you think?
00:51:54 Of course it's a squirrel. These animals are pretty gifted little guys.
00:51:58 They can find their food under 30 cm of snow.
00:52:01 They can also pretend to bury a nut to deceive potential thieves.
00:52:05 But 25% of their reserves end up in the stomach of other squirrels.
00:52:10 And this animal, do you recognize it?
00:52:20 Yes, it's a fox. Did you know that they can emit about 40 different sounds?
00:52:25 Another well-known animal. What do you think?
00:52:29 It's a giraffe. The patterns of their fur are unique.
00:52:38 There are no two giraffes with the same pattern.
00:52:41 In addition, they only drink once every few days, even when they are close to water.
00:52:46 What is this animal?
00:52:49 It's a camel. They can live for weeks without a single drop of water,
00:52:53 that is, longer than giraffes.
00:52:55 For comparison, a human can only last three days without water.
00:52:59 But when camels drink, they can swallow up to 180 liters of water at once.
00:53:04 Do you recognize this one? What is it?
00:53:08 It's a hippopotamus, of course.
00:53:16 They love grass and can eat 36 kilos of it in one night.
00:53:20 Yes, they sleep during the day and get active at night.
00:53:24 And what is this one?
00:53:27 It's a rhinoceros, of course. Rhinoceros have a very bad sight.
00:53:36 If you are 30 meters away and you do not move, they will not see you.
00:53:41 But they have a very strong smell.
00:53:44 In addition, they love mud.
00:53:47 They roll in it and protect them from insects and keep them fresh.
00:53:52 And do you recognize this animal?
00:53:56 It's a mouflette.
00:54:03 Did you know that they are immune to snake venom and can even eat these dangerous animals?
00:54:08 What do you think of this adorable creature?
00:54:12 It's a Greenland seal and its white coat makes it one of the cutest animals on the planet.
00:54:24 But it doesn't last very long.
00:54:27 Greenland seals have this fur until the age of about six weeks.
00:54:31 And what is this?
00:54:34 It's a scorpion.
00:54:36 These creatures are older than dinosaurs.
00:54:39 In addition, they can live a year without food and they shine in the dark.
00:54:44 And this big animal, do you know what it is?
00:54:48 It's a moose.
00:54:56 Did you know that they only live in places where there are two moose?
00:55:00 It's a moose.
00:55:02 Did you know that they only live in places where there is snow in winter?
00:55:06 Do you recognize this animal?
00:55:09 It's a wolf.
00:55:16 They are born completely blind and deaf.
00:55:19 Of course, later, it changes.
00:55:21 An adult wolf can hear up to 15 km per round.
00:55:24 In addition, they have about 200 million olfactory cells.
00:55:28 This animal, do you know what it is?
00:55:31 It's a orangutan.
00:55:39 They are very intelligent and know how to use tools.
00:55:42 They even make gloves with leaves to protect themselves from thorns.
00:55:46 I think you will recognize the following. Tell me.
00:55:56 It's a suricate.
00:55:58 They live in the desert and do not need water to live.
00:56:01 They hydrate by eating insects and other foods.
00:56:05 And this one, do you know his name?
00:56:09 It's a Tasmanian devil.
00:56:17 They are very dangerous.
00:56:19 They bite so hard that the bones break.
00:56:21 They also like to scream and scare other animals.
00:56:24 And a funny detail, they store their fat in their tails.
00:56:28 Next, what is this animal?
00:56:32 It's a squid, of course.
00:56:39 Squid have three hearts.
00:56:41 In addition, they often feed on other smaller squids.
00:56:44 Do you recognize this fish?
00:56:52 It's an electric eel.
00:56:54 Their discharge is so powerful that it can knock down a horse.
00:56:57 In addition, as they have a bad eyesight,
00:57:00 they must emit an electric signal to orient themselves.
00:57:03 According to you, what is this adorable creature?
00:57:07 It's a pandaroo.
00:57:14 Its diet is made up of 97% bamboo.
00:57:17 The remaining 3% include eggs, flowers and small mammals.
00:57:21 In your opinion, what is it?
00:57:24 It's a falconer.
00:57:31 These guys are vegetarian and even if they are strong,
00:57:34 they prefer to run rather than fight.
00:57:36 In addition, as they like to be bathed,
00:57:39 they live in harmony with monkeys.
00:57:41 Come on, one more.
00:57:44 Does this animal tell you something?
00:57:48 It's a porcupine.
00:57:50 A small pig with spines.
00:57:52 They are shy creatures and good swimmers.
00:57:55 As for their stings, they cannot shoot them on their predators.
00:57:58 It's a myth.
00:58:00 However, as they detach easily,
00:58:02 you risk having some on your hands if you touch this animal.
00:58:05 What is it?
00:58:14 It's a marmot.
00:58:17 They sleep all winter and are extremely gifted for construction.
00:58:21 Their houses can be up to 18 meters long.
00:58:24 You will easily guess the name of this animal.
00:58:27 What is it?
00:58:29 Of course, it's an ornithorynchus.
00:58:36 Did you know that their venom is deadly?
00:58:39 But don't worry, no case has yet been reported.
00:58:42 Well, what about this guy?
00:58:44 It's an ornithopteron.
00:58:51 Sometimes called "earth pig".
00:58:53 They live on the African continent
00:58:55 and do not walk exactly on their feet,
00:58:57 only on their toes.
00:58:59 Next, this one has crazy eyes.
00:59:01 What is it called?
00:59:03 It's a black-and-white.
00:59:10 It's an aye-aye.
00:59:12 It's from Madagascar
00:59:14 and has a pretty bad reputation.
00:59:16 The inhabitants think that aye-aye are unlucky.
00:59:19 And this adorable little guy?
00:59:23 It's a prairie dog.
00:59:31 They are not as nice as they look.
00:59:33 They are even rather ferocious.
00:59:35 In addition, they are very intelligent
00:59:37 and have an elaborate vocabulary.
00:59:39 They can warn their peers
00:59:41 when a human approaches.
00:59:43 And this funny bird?
00:59:45 It's an okapi.
00:59:53 They belong to the family of giraffes
00:59:55 and live only in one country,
00:59:57 the Democratic Republic of Congo.
00:59:59 Humans discovered them
01:00:01 a little over 100 years ago, in 1901.
01:00:03 No, it's not a Pokémon,
01:00:06 it's a real animal.
01:00:08 What is it called?
01:00:10 It's a nudibranch.
01:00:18 A sea slug that lives in the shallow
01:00:20 eggs of all the oceans.
01:00:22 This one should be easy.
01:00:24 What is it?
01:00:26 Yes, it's a bison.
01:00:32 Like cats, they purr when they are happy.
01:00:34 And do you know what it is?
01:00:38 It's a margai.
01:00:40 No one knows exactly
01:00:42 how many there are in the world.
01:00:44 And this adorable creature,
01:00:46 what is it?
01:00:48 It's a pika.
01:00:54 They are related to rabbits,
01:00:56 but they are cotton-nosed.
01:00:58 In fact, they have tails,
01:01:00 but you can't see them
01:01:02 because they hide them under their fur.
01:01:04 A little last one,
01:01:06 probably quite difficult.
01:01:08 What is it?
01:01:10 It's a tardigrad.
01:01:17 This microscopic animal has been
01:01:19 on Earth for 600 million years.
01:01:21 It has survived the five great
01:01:23 extinctions of the planet and will
01:01:25 undoubtedly survive any apocalypse.
01:01:27 So, how many good answers do you have?
01:01:31 Tell me everything in the comments.
01:01:34 The smallest heart in the world
01:01:36 is the Mimaridae.
01:01:38 A small insect as thick
01:01:40 as a sheet of paper.
01:01:42 You need a microscope to see its heart.
01:01:44 Contrary to what one might think,
01:01:46 this creature is not a fly.
01:01:48 It is actually a wasp.
01:01:50 If you have the opportunity
01:01:52 to observe one under a microscope,
01:01:54 you will notice the resemblance.
01:01:56 Let's move on to larger hearts,
01:02:02 which are impressive in the animal kingdom.
01:02:04 The zebra fish has a rather nice
01:02:06 hidden talent when it comes to its heart,
01:02:08 which measures only about
01:02:10 1 mm in diameter.
01:02:12 Indeed, its heart can regenerate.
01:02:14 When the heart of a zebra fish
01:02:16 is damaged or has a problem,
01:02:18 it is able, most of the time,
01:02:20 to repair itself.
01:02:22 The human heart is certainly
01:02:24 as impressive as it is,
01:02:26 since it continues to renew
01:02:28 its cells and repair its heart tissue,
01:02:30 which is its zebra.
01:02:32 Let us now look at the example
01:02:34 of the cockroaches.
01:02:36 Our heart is made up of 4 cavities,
01:02:38 each of them having a very precise task
01:02:40 to accomplish.
01:02:42 The global system cannot function
01:02:44 without the 4 cavities working properly.
01:02:46 The heart of a sheet contains 12 to 13 cavities,
01:02:48 placed in rows along the entire length
01:02:50 of the insect's body,
01:02:52 on average about 4 cm.
01:02:54 These cavities work separately
01:02:56 because they are driven by different muscles.
01:02:58 This means that if one of these cavities
01:03:00 is affected, the insect cannot
01:03:02 realize it.
01:03:04 Most of the time, the sheet lives
01:03:06 without all these cardiac cavities
01:03:08 functioning properly.
01:03:10 The heart of a hummingbird
01:03:12 can beat up to 1200 times per minute.
01:03:14 For comparison,
01:03:16 the heart of an athlete
01:03:18 beats only 220 times per minute.
01:03:20 Although it is one of the smallest
01:03:22 hearts in the world,
01:03:24 the hummingbird's heart is quite voluminous,
01:03:26 proportionally to the total size
01:03:28 of the bird.
01:03:30 It represents about 2.5%
01:03:32 of its total weight.
01:03:34 Moreover, the hummingbird
01:03:36 with a blue throat beats up to 15 times
01:03:38 per second.
01:03:40 It is so fast that this movement
01:03:42 cannot be perceived by the human eye.
01:03:44 This impressive speed
01:03:46 is supported by an even faster heart,
01:03:48 which beats 21 times per second.
01:03:50 Have you ever heard
01:03:54 of the Emperor's Humpback?
01:03:56 It is not a kind of humpback
01:03:58 that is content to have a crown on its head,
01:04:00 if that's what you think.
01:04:02 These are fascinating swimmers
01:04:04 who can dive deeper
01:04:06 than any other bird,
01:04:08 at more than 210 meters.
01:04:10 Not to mention that they can stay
01:04:12 submerged for up to 18 minutes in a row
01:04:14 to go and get food.
01:04:16 With a weight of about 140 grams,
01:04:18 their heart is just as spectacular.
01:04:20 Their heart beats very slowly.
01:04:22 When it is in the water,
01:04:24 an Emperor's Humpback can reduce
01:04:26 its heart rate to about 15 beats per minute.
01:04:28 It cuts the supply of blood
01:04:30 from all organs,
01:04:32 except for the most vital ones.
01:04:34 It also reduces its oxygen consumption,
01:04:36 which allows the animal
01:04:38 to use only the necessary strict
01:04:40 to hunt in deep water.
01:04:42 The size of the heart tends
01:04:46 to be quite proportional
01:04:48 throughout the animal kingdom.
01:04:50 For the most part,
01:04:52 this organ represents about 0.6%
01:04:54 of the body mass of an animal.
01:04:56 In comparison,
01:04:58 the heart of dogs and wolves is bigger.
01:05:00 It represents about 0.8%
01:05:02 of the total weight of the animal.
01:05:04 The heart of an average dog
01:05:06 weighs about 560 grams.
01:05:08 If a human heart
01:05:10 suddenly filled with fat,
01:05:12 it would quickly become a problem.
01:05:14 But it is very different for a python.
01:05:16 Indeed,
01:05:18 if this happens to this reptile,
01:05:20 it is a sign that everything is fine.
01:05:22 Pythons tend to eat
01:05:26 very large meals.
01:05:28 After each of these meals,
01:05:30 their heart grows by about 40%.
01:05:32 And as a python
01:05:34 can weigh up to about 110 kg,
01:05:36 40%!
01:05:38 That's a lot!
01:05:40 This phenomenon is due to the fatty acids
01:05:42 absorbed during the meal
01:05:44 that cause an organ inflation.
01:05:46 These reptiles adapted
01:05:48 to accelerate their digestion.
01:05:50 Even if they still need
01:05:52 days to digest a single meal.
01:05:54 Their blood is so loaded
01:05:56 with fatty acids
01:05:58 that it even changes color
01:06:00 and consistency.
01:06:02 In some cases,
01:06:04 it can even become opaque,
01:06:06 resembling more milk than anything else.
01:06:08 Let's finish our list
01:06:12 on the other side of the spectrum
01:06:14 of the animal kingdom.
01:06:16 That of the blue whale.
01:06:18 And for good reason,
01:06:22 it is one of the largest animals.
01:06:24 This giant heart is about
01:06:26 as big as a bathtub
01:06:28 and weighs more than an average gorilla.
01:06:30 No matter their size,
01:06:32 the hearts of animals are amazing.
01:06:34 We humans and most animals
01:06:36 only have one heart.
01:06:38 But this rule does not apply to all creatures.
01:06:40 Let's take the example of peacocks
01:06:42 or squids, which have three hearts.
01:06:44 This is how their system works.
01:06:46 Two of these hearts
01:06:48 send blood to the branches
01:06:50 to guarantee enough oxygen in the body.
01:06:52 While the third heart
01:06:54 pumps blood into the whole body.
01:06:56 Some animals have no heart at all.
01:06:58 This does not necessarily make them mean.
01:07:00 Jellyfish, starfish or corals
01:07:04 lead a rather pleasant life,
01:07:06 even without a heart.
01:07:08 Let's take the example of starfish.
01:07:10 They don't even have blood.
01:07:12 This is probably why
01:07:14 they don't need a heart either.
01:07:16 No list would be complete
01:07:20 without mentioning some surprising facts
01:07:22 about the human heart.
01:07:24 No need to google or look for
01:07:26 an anatomy book to know
01:07:28 the size of your heart.
01:07:30 Just squeeze the point.
01:07:32 The point of a person
01:07:34 is about the same size
01:07:36 as his adult heart.
01:07:38 The heart is active in our body
01:07:40 and can beat about
01:07:42 0.005 thousand times a day.
01:07:44 Have you ever watched
01:07:48 an animated cartoon
01:07:50 in which the main character's heart
01:07:52 starts beating out of his chest?
01:07:54 Most of the time,
01:07:56 we are made to believe that the noise
01:07:58 that our heart makes is produced
01:08:00 when this organ touches the tissues
01:08:02 around it when it beats.
01:08:04 In reality, this noise is produced
01:08:06 by the heart's blood vessels.
01:08:08 These are like small doors
01:08:10 inside our heart
01:08:12 that ensure that the blood
01:08:14 circulates correctly from one side
01:08:16 to the other of the heart.
01:08:18 For our body to function,
01:08:20 the blood must circulate
01:08:22 at the right time and in the right direction.
01:08:24 Our lungs are not twins.
01:08:26 They are brothers and sisters
01:08:28 and our heart is the reason for that.
01:08:30 Our right lung is bigger
01:08:32 and tends to weigh more.
01:08:34 Our right lung
01:08:36 is slightly leaning to the left.
01:08:38 This creates a small gap
01:08:40 in our left lung
01:08:42 called the heart impulse.
01:08:44 The right lung may be bigger
01:08:46 but it is a bit shorter
01:08:48 because it has to make room for the liver.
01:08:50 Speaking of positioning,
01:08:52 our heart is not as left-leaning
01:08:54 as we might think.
01:08:56 It is rather centered,
01:08:58 with a slight inclination to the left.
01:09:00 In people with a dextrocardia,
01:09:02 the heart is located on the right side of the chest.
01:09:04 In itself, this pathology
01:09:06 is not a problem.
01:09:08 But it tends to coincide with other diseases
01:09:10 that can have serious effects
01:09:12 on the heart and other organs.
01:09:14 Did you know that most
01:09:16 heart attacks occur on Mondays?
01:09:18 The reason is still controversial.
01:09:20 But most scientists think
01:09:22 it is due to stress generated
01:09:24 by the start of a new week of work
01:09:26 or the change in our sleep-waking cycle.
01:09:28 We tend to sleep more
01:09:30 during the weekend and wake up
01:09:32 earlier on Monday, which can be
01:09:34 harmful to our heart.
01:09:36 Your heart began beating
01:09:38 about 4 weeks after your conception.
01:09:40 And it will not stop before your death.
01:09:42 Of course, it can weaken
01:09:44 as it ages, but the heart does not get tired.
01:09:46 It is an extremely difficult job
01:09:48 if you think about it.
01:09:50 Try this experiment to check it.
01:09:52 So, hold a tennis ball in your hand.
01:09:54 The beatings of your heart
01:09:56 have about the same force,
01:09:58 but they are different.
01:10:00 I bet you will lose count
01:10:02 before you finish.
01:10:04 In some cases, the energy
01:10:06 our heart needs to keep beating
01:10:08 is unstable.
01:10:10 That's why pacemakers were invented.
01:10:12 They act like small generators
01:10:14 placed inside the human body
01:10:16 and help stabilize abnormal heartbeats.
01:10:18 The very first device of this type
01:10:20 was placed in the body of a woman
01:10:22 named Arno Larson in 1958.
01:10:24 When she died at the age of 86,
01:10:26 it was for other reasons.
01:10:28 It had nothing to do with her heart.
01:10:30 There are sharks that shine in the dark.
01:10:40 For example, the shark "Hool".
01:10:42 They live in the dark depths of the ocean
01:10:44 at a depth of 518 meters
01:10:46 under the surface.
01:10:48 Nobody knows exactly why,
01:10:50 but they emit a fluorescent light
01:10:52 that only the other shark "Hool" can see.
01:10:54 Scientists have detected this light
01:10:56 by using filters that block yellow light.
01:10:58 They think it could be the way
01:11:00 for these big fish
01:11:02 to communicate with their friends.
01:11:04 This light helps these sharks
01:11:06 fight infections at the microbial level.
01:11:08 The "vachées" have secret passwords
01:11:10 that they use to recognize each other.
01:11:12 They are a specific type of parasitic bird
01:11:14 because they lay their eggs
01:11:16 in the nests of other species of birds.
01:11:18 The young "vachées" have an internal mechanism
01:11:20 that allows them to recognize
01:11:22 the song of their species
01:11:24 as a kind of secret password
01:11:26 that only they know.
01:11:28 This is how they manage to find
01:11:30 other birds of their species.
01:11:32 A grizzly has an incredibly strong bite force.
01:11:34 It may seem cute,
01:11:36 but if you approach this big guy,
01:11:38 you'd better stay out of reach
01:11:40 of his sharp claws
01:11:42 and especially of his mouth.
01:11:44 His bite force is more than 8 million Pascals,
01:11:46 which means he can crush
01:11:48 a bowling ball.
01:11:50 Some animals have thick stripes,
01:11:52 others are more superficial.
01:11:54 Tigers are part of the first group.
01:11:56 Not only their fur is striped,
01:11:58 but their skin is too.
01:12:00 It's the same for other big fur felines
01:12:02 like snow leopards.
01:12:04 Giraffes and zebras
01:12:06 are part of the second group
01:12:08 because they have patterns
01:12:10 only on their fur.
01:12:12 Speaking of zebras,
01:12:14 do you think they are black with white stripes
01:12:16 or white with black stripes?
01:12:18 It seems that the second option is the right one.
01:12:20 Their black stripes
01:12:22 end mainly inside their legs
01:12:24 and on their bellies,
01:12:26 and the rest is white.
01:12:28 But it's not true. Surprisingly,
01:12:30 they are black with white stripes.
01:12:32 All their fur, whether white or black,
01:12:34 grows from follicles
01:12:36 containing cells called melanocytes.
01:12:38 All animals have these cells.
01:12:40 They produce a pigment called melanin
01:12:42 that gives color to their hair
01:12:44 and skin.
01:12:46 The chemical message indicates
01:12:48 which melanocyte sends the pigment
01:12:50 to which area of the fur.
01:12:52 That's why zebras have black and white patterns.
01:12:54 But white is not a pure pigment.
01:12:56 It's a lack of melanin.
01:12:58 Black is their default color.
01:13:00 Koalas have fingerprints
01:13:02 so close to ours
01:13:04 that they could even alter crime scenes.
01:13:06 Apparently, they don't have much in common
01:13:08 with humans.
01:13:10 But look closely at their hands.
01:13:12 They have distinctive loops and arches.
01:13:14 So if a koala wants to do something illegal,
01:13:16 it would be good if it wore gloves.
01:13:18 Phantom crabs
01:13:20 growl when they are in the presence
01:13:22 of creatures they don't like or find threatening.
01:13:24 They do it by using
01:13:26 their stomach teeth.
01:13:28 First, they let you know that they will defend themselves
01:13:30 if you try something by showing you their claws.
01:13:32 If it doesn't work,
01:13:34 they emit a scary growling like dogs.
01:13:36 But the noise comes from
01:13:38 rubbing their three long and hard teeth
01:13:40 inside their stomach.
01:13:42 Phantom crabs make the same noise
01:13:44 when they chew food.
01:13:46 Speaking of teeth,
01:13:48 did you know that narwhal's defense
01:13:50 is actually a kind of upside-down tooth?
01:13:52 Unlike most other whales,
01:13:54 narwhals are the only ones
01:13:56 to have a large defense, or tooth,
01:13:58 that grows inside their jaw.
01:14:00 They have up to
01:14:02 10 million nerve endings
01:14:04 that are not protected,
01:14:06 which means that their defense is very sensitive
01:14:08 to all kinds of contact.
01:14:10 It's almost like a piece of skin
01:14:12 because defense generally doesn't have
01:14:14 many nerve endings.
01:14:16 Nearly 95% of humans are right-handed,
01:14:18 and it's the same for dolphins.
01:14:20 There are even more right-handed people
01:14:22 among them than among humans.
01:14:24 In a research, scientists
01:14:26 discovered that dolphins
01:14:28 turn to the left more than 99% of the time,
01:14:30 which means they are right-handed.
01:14:32 They place their right side
01:14:34 and their right eye closer to the bottom of the ocean
01:14:36 when they go to look for their prey,
01:14:38 such as squids, shrimps,
01:14:40 or small fish.
01:14:42 Other interesting facts about the ocean.
01:14:44 Did you know that humpback whales
01:14:46 use bubbles when they chase their prey?
01:14:48 We might think that they don't need
01:14:50 any particular method, given their size,
01:14:52 but when they chase their prey in deep waters,
01:14:54 these whales team up
01:14:56 and use a technique called "bubble netting".
01:14:58 While swimming in an ascending spiral,
01:15:00 they blow bubbles underwater.
01:15:02 These bubbles prevent the fish from escaping.
01:15:04 The oldest evidence
01:15:06 that we have of domesticated cats
01:15:08 dates back to 12,000 years ago.
01:15:10 Researchers discovered it 20 years ago
01:15:12 by digging in an ancient village in Cyprus.
01:15:14 They found bones of cats
01:15:16 right next to human bones,
01:15:18 which suggests they were close
01:15:20 even when their lives were coming to an end.
01:15:22 Humans were hunters,
01:15:24 so they domesticated dogs first
01:15:26 about 29,000 years ago.
01:15:28 Dogs helped them catch other animals,
01:15:30 but they didn't think they needed cats
01:15:32 until they began to sedentary
01:15:34 and stock up on food.
01:15:36 Mice are often found
01:15:38 in cereal stores,
01:15:40 and cats proved to be very useful
01:15:42 at this time.
01:15:44 Macaws are very ingenious
01:15:46 when they want to scratch their bodies.
01:15:48 They can probably be proud
01:15:50 of their magnificent beaks,
01:15:52 but they obviously think it's not enough to scratch.
01:15:54 Researchers have found that they tend
01:15:56 to spontaneously take a small wooden stick
01:15:58 to scratch a place that eats them.
01:16:00 There is a special type of ant
01:16:02 that only lives in a small part of Manhattan.
01:16:04 Broadway's "Earth Full"
01:16:06 between 63rd and 76th Streets
01:16:08 is the place that these rampant creatures
01:16:10 have decided to choose.
01:16:12 The manatee ant seems to come from Europe,
01:16:14 but no European species
01:16:16 can really look like it.
01:16:18 Hey, Potter fans,
01:16:20 can you believe there is such a thing
01:16:22 as a chocolate frog?
01:16:24 Well, not exactly,
01:16:26 but it looks like it.
01:16:28 New Guinea and Australia
01:16:30 have not always been separated.
01:16:32 They have spent millions of years together
01:16:34 until, about 12,000 years ago,
01:16:36 the sea level separated them.
01:16:38 As they have stayed together for so long,
01:16:40 some animals and some plants
01:16:42 still live in both regions,
01:16:44 including the White's frogs.
01:16:46 These frogs have spread very far,
01:16:48 and some of them,
01:16:50 who live in hot and swampy regions
01:16:52 surrounded by many crocodiles,
01:16:54 seem to be chocolate.
01:16:56 We all know pink flamingos
01:16:58 for their particular colour,
01:17:00 but they are not really pink.
01:17:02 They are born grey and would remain so
01:17:04 if they did not feed on blue algae
01:17:06 and shrimp.
01:17:08 These foods contain a specific natural colour,
01:17:10 which explains why pink flamingos' feathers
01:17:12 turn pink over time.
01:17:14 When Tasmanian little devils
01:17:16 grow up and leave their mother,
01:17:18 they regroup and form bonds
01:17:20 that last a lifetime.
01:17:22 Cows also have stronger social bonds
01:17:24 than we think.
01:17:26 They are also more likely to
01:17:28 befriend each other.
01:17:30 A study has even shown that their
01:17:32 heart rate increases significantly
01:17:34 in signs of stress when they are
01:17:36 separated from their best friends.
01:17:38 Imagine that you can simply freeze
01:17:40 during the cold winter days
01:17:42 instead of listening to your teeth
01:17:44 crack and trying to close your jacket.
01:17:46 This is what frogs can do.
01:17:48 Aquatic frogs mainly hibernate
01:17:50 underwater and spend most of the winter
01:17:52 at the bottom of a pond,
01:17:54 where they can't swim.
01:17:56 Frogs and toads generally have cold blood,
01:17:58 which means that the temperature of their body
01:18:00 is similar to that of their environment.
01:18:02 Thus, frogs can freeze during the winter
01:18:04 due to a high concentration of sugar
01:18:06 or glucose in their vital organs.
01:18:08 Once frozen,
01:18:10 they continue as if nothing had happened.
01:18:12 Pigeons have three hearts
01:18:14 and blue blood.
01:18:16 They can move at a speed of 40 km/h
01:18:18 and project ink,
01:18:20 which not only blurs the predator's visual field,
01:18:22 but also makes it darker.
01:18:24 Pigeons also have nine brains,
01:18:26 the central brain
01:18:28 and eight smaller brains located in their arms.
01:18:30 This is why their arms can open a shell
01:18:32 while the central brain
01:18:34 is busy doing something else.
01:18:36 A pigeon even tastes with its arms.
01:18:38 It has cells in its ventral cavity
01:18:40 that allow the arm to touch
01:18:42 and taste in order to detect
01:18:44 the chemical substances produced
01:18:46 by marine creatures.
01:18:48 In this way, a pigeon can distinguish
01:18:50 between a frog and a frog.
01:18:52 You work in a large natural reserve
01:18:54 that houses more than a thousand species of animals.
01:18:56 At night, you drive through the area
01:18:58 in a jeep to see if everything is going well.
01:19:00 Most of the animals are asleep.
01:19:02 Suddenly, you hear the monkeys screaming.
01:19:04 They jump from branch to branch.
01:19:06 A herd of wild horses
01:19:08 come out of the forest running.
01:19:10 They seem worried too.
01:19:12 You hear many animals crying.
01:19:14 It seems that a strange and unknown thing
01:19:16 has awakened and horrified
01:19:18 the whole reserve.
01:19:20 You see a flash in the night sky.
01:19:22 It's a meteorite
01:19:24 and it flies straight at you.
01:19:26 You get in your car,
01:19:28 you press the accelerator
01:19:30 and you move as far as possible.
01:19:32 The space rock falls right in front of you
01:19:34 and projects your vehicle on the side.
01:19:36 You faint.
01:19:38 The meteorite falls
01:19:40 and emits a strange yellow glow.
01:19:42 You are unconscious inside your car,
01:19:44 upside down.
01:19:46 The animals have calmed down.
01:19:48 Thousands of them approach
01:19:50 the meteorite silently.
01:19:52 Its energy envelops you
01:19:54 and all the animals around.
01:19:56 The more energy it radiates,
01:19:58 the smaller the space rock.
01:20:00 In the morning, the meteorite evaporates in the air.
01:20:02 It has absorbed the power of the animals
01:20:04 and transmitted it to you.
01:20:06 You wake up in the grass
01:20:08 near your car, surrounded by several people.
01:20:10 These are the employees of the reserve
01:20:12 and dark-clad agents.
01:20:14 They study the crater in the ground
01:20:16 and ask you what happened.
01:20:18 You tell them about the meteorite
01:20:20 and they order you to follow them.
01:20:22 One of them grabs you tightly by the shoulders.
01:20:24 You don't like it and you want to escape.
01:20:26 Two agents hold you.
01:20:28 You get angry
01:20:30 and you feel your muscles contract
01:20:32 and your skin is covered with fur.
01:20:34 You quickly push back the men
01:20:36 and you roar.
01:20:38 Your nails have turned into claws.
01:20:40 You have received the powers of a bear
01:20:42 that is as strong and ferocious.
01:20:44 You flee into the forest,
01:20:46 but the agents follow you.
01:20:48 You want to be faster
01:20:50 and you feel your spine change shape.
01:20:52 You run now on all fours very fast.
01:20:54 You have the power of the cheetah,
01:20:56 the fastest animal on earth.
01:20:58 It's incredible!
01:21:00 You can use your mind
01:21:02 to acquire the powers of any animal.
01:21:04 You hide in the forest.
01:21:06 The agents are far behind you.
01:21:08 You hear a helicopter in the sky.
01:21:10 They project a beam of light from a projector.
01:21:12 Ouch! They noticed you!
01:21:14 The agents use a megaphone
01:21:16 to ask you to stop.
01:21:18 But you know what awaits you.
01:21:20 Laboratories, experiments,
01:21:22 life in a cage.
01:21:24 You have seen a lot of movies about it,
01:21:26 so you won't give up.
01:21:28 You run out of the forest.
01:21:30 They shoot arrows at you.
01:21:32 You quickly head towards a large lake
01:21:34 and dive in.
01:21:36 Branches form on your neck.
01:21:38 It's so good to let water flow through it.
01:21:40 Palms have grown on your arms
01:21:42 and your legs.
01:21:44 Your feet are like fins.
01:21:46 Your legs merge to form a long tail
01:21:48 and you are now a morse.
01:21:50 You quickly cross the lake while swimming
01:21:52 and land on the other side of the shore.
01:21:54 Several cars and motorcycles
01:21:56 go around the lake to catch up with you.
01:21:58 There is another forest in front of you,
01:22:00 but this time it is too dense.
01:22:02 There is no space to run fast,
01:22:04 but you can have the strength of a monkey.
01:22:06 Your hands stretch
01:22:08 and your fingers become stronger.
01:22:10 You jump on a tree,
01:22:12 you climb to the top
01:22:14 and you scan the reserve with your eyes.
01:22:16 You have to go south
01:22:18 and reach a small town to recover.
01:22:20 After a few hours,
01:22:22 you reach the limit of the reserve.
01:22:24 You now have to jump over a high cliff.
01:22:26 Your legs become strong.
01:22:28 You jump like a kangaroo,
01:22:30 but it's not high enough.
01:22:32 You fall to the ground.
01:22:34 A helicopter catches up with you.
01:22:36 You acquire the powers of a lizard.
01:22:38 Sticky scales grow on your palms.
01:22:40 You quickly climb the concrete wall
01:22:42 and jump on the other side.
01:22:44 You find yourself in the tall grass.
01:22:46 Agents come to you from all sides.
01:22:48 You think of transforming yourself into a snake.
01:22:50 Your arms and legs merge with your body.
01:22:52 You can now crawl.
01:22:54 You pass in front of all the agents
01:22:56 and you find yourself on the road.
01:22:58 You see a car in the distance.
01:23:00 You raise your hand
01:23:02 and it asks you to stop.
01:23:04 Oh no, it's the agent's car!
01:23:06 It surrounds you.
01:23:08 The helicopter's projector is pointed at you.
01:23:10 You have nowhere to go.
01:23:12 But you can fly!
01:23:14 Your clothes rip in your back.
01:23:16 Huge wings grow from your shoulder blades.
01:23:18 You rise in the air.
01:23:20 It's pretty cold here,
01:23:22 but the feathers on your body protect you from the wind.
01:23:24 Great! You can fly!
01:23:26 It's incredible, but...
01:23:28 Ouch! You feel like someone pinched you from behind.
01:23:30 It's an arrow.
01:23:32 They got you.
01:23:34 You want to sleep,
01:23:36 but you let yourself go down.
01:23:38 You land abruptly near a small wooden house.
01:23:40 Agents run to you.
01:23:42 You acquire the powers of another animal
01:23:44 and you faint.
01:23:46 The agents search the house,
01:23:48 but can't find you.
01:23:50 Maybe the arrow with the sleeping pill didn't work on you.
01:23:52 After a few minutes,
01:23:54 they leave again.
01:23:56 During this time, you sleep peacefully
01:23:58 on the wall of the house.
01:24:00 At the last second,
01:24:02 you acquire the powers of a chameleon.
01:24:04 You merge with the wall
01:24:06 and become invisible.
01:24:08 You sleep a few more hours.
01:24:10 The sun rises.
01:24:12 A rusty Jeep stops in the yard.
01:24:14 An old man and a dog come out.
01:24:16 The dog runs to you
01:24:18 and starts licking your face.
01:24:20 The old man realizes that there is an invisible person in front of him.
01:24:22 You regain your senses
01:24:24 and tell the old man what happened to you.
01:24:26 He gives you food
01:24:28 and clean clothes.
01:24:30 You thank him and leave.
01:24:32 Now, you have to leave the country as soon as possible.
01:24:34 You think of transforming yourself
01:24:36 into a bat.
01:24:38 Palm-shaped wings grow in your back
01:24:40 and you have cramps.
01:24:42 You fly without seeing anything.
01:24:44 Your sight is deteriorated,
01:24:46 but your hearing is simply fantastic.
01:24:48 You have the power of echolocation
01:24:50 and you can emit ultrasonic waves
01:24:52 at high frequencies.
01:24:54 When you go far away,
01:24:56 you hear the cry of a familiar person.
01:24:58 Oh no, it's the old man!
01:25:00 The agents have caught him.
01:25:02 You turn around and fly directly
01:25:04 to the house.
01:25:06 One of the agents sees you.
01:25:08 He screams in terror.
01:25:10 You land and transform yourself into a rhinoceros.
01:25:12 Your body becomes huge
01:25:14 and your nose extends.
01:25:16 You accelerate and knock down several agents.
01:25:18 Then you turn their car around,
01:25:20 run into the house and free the old man.
01:25:22 He climbs on your back because you are now a horse
01:25:24 and you are going far away.
01:25:26 You reach the mountains.
01:25:28 The old man looks tired but grateful.
01:25:30 You can't share his joy
01:25:32 because you don't know how it's all going to end.
01:25:34 You ask the old man to hide
01:25:36 while you distract the pursuers.
01:25:38 You think of another animal.
01:25:42 Your legs and arms transform into a sabo.
01:25:44 You climb on top of a cliff like a goat.
01:25:46 They can't catch you.
01:25:48 But at that moment,
01:25:50 the helicopter appears again.
01:25:52 An agent aims at you with an arrow.
01:25:54 Needles grow in your back.
01:25:56 You have the powers of an epic pig.
01:25:58 You shoot some needles at the agent.
01:26:00 This distracts him for a few minutes.
01:26:02 At that moment,
01:26:04 a puma jumps on you
01:26:06 from nowhere.
01:26:08 He grabs you.
01:26:10 You think of a lion and get his powers.
01:26:12 You put yourself on your hind legs and roar very loudly.
01:26:14 The puma gets scared and runs away.
01:26:16 The helicopter flies away.
01:26:18 You speed up, jump off the cliff
01:26:20 and get the powers of the fastest bird in the world,
01:26:22 the falcon.
01:26:24 You make a quick dive
01:26:26 and land in the forest.
01:26:28 You must now find the old man.
01:26:30 You have a dog's muzzle.
01:26:32 You can now smell your friend
01:26:34 and go to him.
01:26:36 At that moment,
01:26:38 you find an excellent plan to stop the agents.
01:26:40 Lions, elephants and bears.
01:26:44 Three of the most majestic members
01:26:46 of the animal kingdom.
01:26:48 Could there be something
01:26:50 that intimidates these creatures?
01:26:52 You might be surprised.
01:26:54 Let's start with the king
01:26:56 universally recognized by animals,
01:26:58 the lion.
01:27:00 Some claim that this big cat
01:27:02 from the savannah
01:27:04 is afraid of the most vital substance
01:27:06 known to man.
01:27:08 A little hint,
01:27:10 it covers 70% of the Earth's surface.
01:27:12 Really?
01:27:14 The lion would be afraid of water.
01:27:16 No, it's a myth.
01:27:18 Lions like to bathe,
01:27:20 especially because it allows them to refresh themselves.
01:27:22 This makes sense when we think of the climate
01:27:26 in which these creatures must live.
01:27:28 The temperatures in a savannah climate
01:27:30 range from 20 to 30 degrees.
01:27:32 We humans
01:27:34 really want to go to the beach
01:27:36 as soon as the weather is warm.
01:27:38 So why should we expect something different
01:27:40 from the lion?
01:27:42 We consider that these creatures
01:27:44 generally weigh between 127 and 190 kilos,
01:27:46 twice the weight of a fur coat.
01:27:48 The irony of this myth
01:27:52 is that lions are afraid of water
01:27:54 and are excellent swimmers.
01:27:56 The same goes for all the other big cats
01:27:58 in these hot climates,
01:28:00 such as tigers, leopards,
01:28:02 jaguars and ocelots.
01:28:04 It is the big cats
01:28:06 in cold climates
01:28:08 that do their best to avoid water.
01:28:10 They apply this to felines
01:28:12 such as wild cats, lynxes and snow leopards.
01:28:14 These animals live in the cold biome
01:28:18 of the Alpine tundra,
01:28:20 a rocky and mountainous area.
01:28:22 The temperatures there drop to 1 degree.
01:28:24 Once again, it is perfectly logical
01:28:28 that these big cats in cold climates
01:28:30 are afraid of water.
01:28:32 Soaking their fur would reduce their chances
01:28:34 of maintaining their heat.
01:28:36 But we must not go far
01:28:38 without understanding where the myth
01:28:40 that lions are afraid of water comes from.
01:28:42 In fact, there is a good chance
01:28:44 that the reason is near
01:28:46 your computer screen right now,
01:28:48 jumping everywhere
01:28:50 and doing stupid things.
01:28:52 It is true that we may have jumped
01:28:54 a little too quickly to the conclusion
01:28:56 that some behavioral aspects
01:28:58 of our own cats would correspond
01:29:00 to those of a lion.
01:29:02 Domestic cats,
01:29:04 although related to all the big felines
01:29:06 in the world, do not come
01:29:08 directly from them.
01:29:10 They have developed over millions of years
01:29:12 from a single wild ancestor
01:29:14 that still exists today in nature,
01:29:16 the wild cat of Africa.
01:29:18 As the water is not abundant
01:29:20 in North Africa and the Middle East,
01:29:22 these cats have not been exposed much there.
01:29:24 And like their descendants,
01:29:26 they only appreciate it for drinking it.
01:29:28 As you probably see
01:29:30 with your pet,
01:29:32 they rarely bathe and interact
01:29:34 with the water in general.
01:29:36 Fortunately for them,
01:29:38 they do not need it.
01:29:40 These domestic cats use their tongues
01:29:42 to clean themselves.
01:29:44 It is equipped with tiny hooks
01:29:46 that help cats to make the knots
01:29:48 disappear and keep their fur clean.
01:29:50 Very fragrant and in a generally
01:29:52 impeccable state.
01:29:54 Cats are generally
01:29:56 fiercely individualistic creatures.
01:29:58 And you may be insulting yourself
01:30:00 in front of your screen
01:30:02 for your own sake.
01:30:04 Some cats even like to play with,
01:30:06 for example, the drops of the tap
01:30:08 or the bubbles in your bath.
01:30:10 There are specific breeds
01:30:12 of domestic cats
01:30:14 known to appreciate aquatic life
01:30:16 more than others.
01:30:18 The Turk of Van, for example,
01:30:20 which is also known
01:30:22 under the appropriate name of "swimmer cat".
01:30:24 We think that this breed has developed
01:30:26 an affinity for water by swimming
01:30:28 in Lake Van to cool off.
01:30:30 It is a very popular place
01:30:32 where these animals have evolved.
01:30:34 Let's now turn to a problem
01:30:36 that a cat has absolutely no way of dealing with.
01:30:38 Have you ever heard of
01:30:40 "musophobia"?
01:30:42 Also known as "suriphobia",
01:30:44 these two words mean
01:30:46 a fear of mice and rats.
01:30:48 There is a popular belief
01:30:50 that the elephant suffers from this phobia.
01:30:52 This animal measures
01:30:54 about 3 meters
01:30:56 and weighs 4,000 kg.
01:30:58 And he would be afraid of a creature
01:31:00 that only measures 10 cm
01:31:02 and weighs less than a few grams?
01:31:04 How did this belief come about?
01:31:06 Well, the basis of this rumor
01:31:08 is the possibility
01:31:10 that elephants are indeed
01:31:12 paranoid,
01:31:14 so that mice can climb
01:31:16 into their trunks.
01:31:18 If a mouse managed to do it,
01:31:20 there would be a risk that it would cause
01:31:22 an irritation and a blockage
01:31:24 inside it.
01:31:26 But in the case of the elephant,
01:31:28 this belief is also a myth.
01:31:30 Researchers say that there is
01:31:32 no concrete evidence
01:31:34 that elephants are afraid of mice.
01:31:36 Moreover, they say that
01:31:38 the gigantic animal can sometimes
01:31:40 be afraid of the sudden appearance
01:31:42 of the little rodent,
01:31:44 which is exactly the same for us.
01:31:46 Experts also say that even if
01:31:48 a mouse managed to get into
01:31:50 the trunk of an elephant,
01:31:52 it could make it come out
01:31:54 of the trunk of the elephant.
01:31:56 There is also evidence that in most cases,
01:31:58 the animal is not disturbed by rodents
01:32:00 and even allows mice to climb
01:32:02 on its head and trunk.
01:32:04 Researchers are sure that as long as
01:32:06 an elephant is in good health,
01:32:08 there is no other animal that it fears,
01:32:10 and this simply because of its size.
01:32:12 Thus, elephants are not afraid of water
01:32:14 and elephants do not seem to be afraid
01:32:16 of mice.
01:32:18 But is at least one of these rumors
01:32:20 of animal fear true?
01:32:22 It is a question of whether
01:32:24 the bear has a legitimate fear.
01:32:26 Well, it would be to count
01:32:28 without the best friend of man.
01:32:30 Yes, bears feel quite uncomfortable
01:32:34 when they are in the presence of dogs,
01:32:36 and this despite a genetic relationship
01:32:38 distant with them.
01:32:40 When the two creatures meet,
01:32:42 the dog is able to chase, intimidate,
01:32:44 trap or counteract the bear.
01:32:46 As for the powerful animal,
01:32:48 it will rather try to avoid
01:32:50 any confrontation with the dog.
01:32:52 There is even a Finnish dog breed
01:32:54 known as "Kareli's Bear Dog".
01:32:56 This species is specially used
01:32:58 to hold the heads of large animals
01:33:00 like bears.
01:33:02 This dog has an excellent sense
01:33:04 of orientation, great flexibility
01:33:06 and mastery of its body, courage,
01:33:08 a good smell and perseverance.
01:33:10 This means that you can walk
01:33:12 with your dog in a known area
01:33:14 to shelter bears and feel
01:33:16 absolutely serene and confident
01:33:18 thanks to the presence of your faithful companion.
01:33:20 Not really.
01:33:22 Even if bears can be nervous
01:33:24 in the presence of dogs,
01:33:26 we must not forget their size or their power.
01:33:28 The American black bear can reach
01:33:30 a height of nearly 2 meters
01:33:32 and weigh up to 300 kg.
01:33:34 If a bear mother has nowhere to go
01:33:36 or if she feels that her cubs are in danger,
01:33:38 it is quite possible
01:33:40 that she gets angry,
01:33:42 which can lead to big problems
01:33:44 for you or your dog.
01:33:46 No one should ever try this theory.
01:33:48 Instead, if you plan to visit
01:33:50 an unknown area with your dog one day,
01:33:52 you should first familiarize yourself
01:33:54 with the fauna you will encounter there.
01:33:56 Because you never know
01:33:58 what a bear will do
01:34:00 when it notices you with your puppy,
01:34:02 especially if you take into account
01:34:04 their slight xenophobia,
01:34:06 which is the name given to the fear of dogs.
01:34:08 At least we have managed
01:34:10 to find a real fear of another animal
01:34:12 among these three cadors
01:34:14 of the food chain.
01:34:16 But isn't it strange that the dog
01:34:18 that brings so much joy and comfort
01:34:20 to many of us is also
01:34:22 a rather puny creature
01:34:24 to confront a bear?
01:34:26 Well, not all heroes wear a cape.
01:34:28 Some simply wear fur and a collar.
01:34:30 And while we're at it,
01:34:32 why not take a look
01:34:34 at what frightens our faithful fur companions?
01:34:36 Have you ever wondered
01:34:38 why your dog is uncomfortable
01:34:40 when it hears loud noises?
01:34:42 The answer varies for each dog,
01:34:44 but it is the simple unpredictability
01:34:46 of the thunder and lightning
01:34:48 or strong detonations
01:34:50 accompanied by fireworks
01:34:52 that cause your dog to be uncomfortable.
01:34:54 The inability to understand
01:34:56 what causes this deafening noise
01:34:58 can cause your dog to tremble,
01:35:00 to get his tail between his legs
01:35:02 or even to run away from home.
01:35:04 Another situation that can really
01:35:06 frighten your faithful fur companions
01:35:08 is when we leave them alone.
01:35:10 This can unfortunately become
01:35:12 a nightmare for your neighbors
01:35:14 because a common symptom of this fear
01:35:16 is excessive barking.
01:35:18 This fear can also cause problems
01:35:20 closer to home.
01:35:22 Have you ever wondered
01:35:24 why your dog had scratched your sofa?
01:35:26 These learning accidents are typical
01:35:28 when a dog suffers from anxiety
01:35:30 due to separation.
01:35:32 But you can't stay angry
01:35:34 against your dog for long, can you?
01:35:36 Your best friend will catch up
01:35:38 with you.
01:35:40 The megalodon was one of the largest
01:35:42 and fiercest creatures on our planet.
01:35:44 Powerful jaws,
01:35:46 sharp teeth like razors,
01:35:48 gigantic size.
01:35:50 But did you know the sound it made?
01:35:52 Imagine the grunt
01:35:54 imbuing the underwater world
01:35:56 with sound vibrations.
01:35:58 This sound was like nothing else.
01:36:00 The megalodon did not make a sound.
01:36:02 It was a shark
01:36:04 and it had no sound-producing organs.
01:36:06 But you could have heard it anyway.
01:36:08 Imagine yourself underwater,
01:36:10 raise your hand and lower it quickly.
01:36:12 Now imagine you have a big submarine
01:36:14 instead of your hand.
01:36:16 You hear the water moving around the hull.
01:36:18 That's what the megalodon's sound
01:36:20 sounded like.
01:36:22 When this monster climbed to the surface
01:36:24 and opened its jaws,
01:36:26 it made the sound of a waterfall.
01:36:28 This giant shark swam at high speed.
01:36:30 When the water passed through its mouth
01:36:32 and its gills,
01:36:34 it made a powerful roar.
01:36:36 The megalodon
01:36:38 did not make a sound,
01:36:40 except for the water flowing.
01:36:42 Other ancient fish could make sounds,
01:36:44 but they were barely heard.
01:36:46 I'm not talking about whales, dolphins
01:36:48 and their ancestors,
01:36:50 because they are mammals.
01:36:52 Fish communicated on frequencies
01:36:54 inaudible to the human ear.
01:36:56 Some still have this ability.
01:36:58 But overall, the ocean was
01:37:00 and remains a rather quiet place.
01:37:02 So we went to ancient lands
01:37:04 to hear what kind of sounds were produced.
01:37:06 Thanks to modern technology,
01:37:08 scientists can recreate
01:37:10 the sounds produced by many
01:37:12 missing species.
01:37:14 Using scanners,
01:37:16 they discovered that some dinosaurs
01:37:18 had complex systems of small holes
01:37:20 in the skull that allowed them
01:37:22 to produce a wide range of sounds
01:37:24 and regulate the temperature of their bodies.
01:37:26 And we managed to recreate them.
01:37:28 The vegavis,
01:37:30 an ancient bird that lived
01:37:32 from 79 to 145 million years ago,
01:37:34 made a similar cry
01:37:36 to that of some low-ranking birds
01:37:38 like ducks and eagles.
01:37:40 But this creature
01:37:42 made it much more frightening.
01:37:44 Scientists discovered it
01:37:46 thanks to a syrinx fossil
01:37:48 found in 2016 in Antarctica.
01:37:50 It is the oldest vocal organ
01:37:52 known in the world.
01:37:54 It helped the vegavis
01:37:56 to produce a double quaking.
01:37:58 Imagine a nut and a duck
01:38:00 that cry and multiply the volume.
01:38:02 That's what its cry sounded like.
01:38:04 Other flying reptiles,
01:38:06 like the pterodactyl,
01:38:08 couldn't cry like the vegavis
01:38:10 because it didn't have a syrinx.
01:38:12 These winged monsters could groan,
01:38:14 whistle and clack their beaks
01:38:16 and it was already very effective.
01:38:18 Take any great basketball player.
01:38:20 The pterodactyl's skull
01:38:22 was slightly larger.
01:38:24 Imagine the noise the dinosaur made
01:38:26 when it clacked such a beak.
01:38:28 It must have been enough
01:38:30 to scare other creatures.
01:38:32 You probably know the noise
01:38:34 a tyrannosaur makes thanks to movies.
01:38:36 And you would recognize among thousands
01:38:38 its roar, similar to a trombone,
01:38:40 a vacuum cleaner and a horn.
01:38:42 Well, this roar is not really close
01:38:44 to the real sound this monster
01:38:46 could emit.
01:38:48 Thanks to modern technology
01:38:50 and well-preserved fossils,
01:38:52 scientists have managed to simulate
01:38:54 the sound of a tyrannosaur's roar.
01:38:56 Imagine you're downloading
01:38:58 T-rex data in a program
01:39:00 and you're getting ready
01:39:02 to hear its terrifying roar.
01:39:04 You press play and...
01:39:06 it sounds like a gas.
01:39:08 The cry of the tyrannosaurus rex
01:39:10 was more like a bird's
01:39:12 and not a mammal's.
01:39:14 But it wasn't just a cry.
01:39:16 It used its nostrils to scream
01:39:18 and not its mouth.
01:39:20 A burble came out of its chest
01:39:22 and it sounded much more intimidating
01:39:24 than what you see in movies.
01:39:26 It was louder than all the trumpets
01:39:28 of a symphonic orchestra.
01:39:30 And it did it only
01:39:32 through its nose.
01:39:34 We don't know for sure
01:39:36 if it could roar or not by its mouth.
01:39:38 We can also hear the sound
01:39:40 of long-nosed dinosaurs in movies.
01:39:42 Their cries were similar to those
01:39:44 of elephants, something between
01:39:46 a saxophone and a car horn.
01:39:48 But in fact, these big creatures
01:39:50 were whispering.
01:39:52 Almost all mammals emit sounds
01:39:54 through their laryngeal nerves.
01:39:56 This nerve goes down the neck
01:39:58 and then goes around the blood vessels
01:40:00 of the chest and back to the larynx.
01:40:02 Basically, the brain gives a signal
01:40:04 and it goes twice the distance
01:40:06 of the neck before going out of the mouth.
01:40:08 Remember the long-nosed dinosaur.
01:40:10 It was the height of a five-story building.
01:40:12 But the vocal signal had to go
01:40:14 the equivalent of ten floors.
01:40:16 It took a long time
01:40:18 which affected their roar.
01:40:20 So when it wanted to emit a sound,
01:40:22 it simply whistled
01:40:24 like a giant viper.
01:40:26 But the most detailed sound
01:40:28 that scientists have managed to obtain
01:40:30 is that of the Parasaurolophus.
01:40:32 We recognize this herbivorous dinosaur
01:40:34 thanks to its long crest
01:40:36 at the back of its head.
01:40:38 In movies and documentaries,
01:40:40 it is used to fight its opponents.
01:40:42 Some scientists think
01:40:44 they also used it to drop fruits
01:40:46 and leaves from trees.
01:40:48 Others think they needed it
01:40:50 to improve their smell.
01:40:52 But it turned out that in addition
01:40:54 to defending and fighting,
01:40:56 they used their crest to emit
01:40:58 powerful and frightening sounds
01:41:00 in different tones.
01:41:02 Scientists reproduced them
01:41:04 with fantastic precision
01:41:06 thanks to the structure of this hard tissue.
01:41:08 Almost all living beings
01:41:10 with a voice use soft organs
01:41:12 to emit sounds.
01:41:14 The Parasaurolophus
01:41:16 had solid organs.
01:41:18 On a skull,
01:41:20 tubes connected the nostrils
01:41:22 to the crest and came back to the latter.
01:41:24 It was like a turntable,
01:41:26 a curved instrument.
01:41:28 This proves that this dinosaur
01:41:30 used the crest at the back of its head
01:41:32 to amplify its cries,
01:41:34 which allowed it to "clarinate"
01:41:36 so that its relatives could hear it in the forest.
01:41:38 It produced a kind of murmur
01:41:40 with low and high notes.
01:41:42 Mix a saxophone and a trumpet
01:41:44 with the cry of a walnut,
01:41:46 a car horn,
01:41:48 and add low frequencies,
01:41:50 then increase the volume.
01:41:52 That's what the Parasaurolophus's cry
01:41:54 looked like.
01:41:56 That's also what my class of CM1 looked like.
01:41:58 You can listen to different sounds
01:42:00 of this dinosaur on the Internet.
01:42:02 It emitted different tones
01:42:04 to create complex social links.
01:42:06 It could communicate, identify,
01:42:08 announce a danger,
01:42:10 or signal its friendly intentions.
01:42:12 We just heard the sound
01:42:14 of some ancient reptiles.
01:42:16 But what about the ancient insects?
01:42:18 They didn't have vocal cords,
01:42:20 but they used friction
01:42:22 between certain parts of their bodies.
01:42:24 Look at the modern crickets
01:42:26 that play with their wings.
01:42:28 One wing has tiny notches,
01:42:30 and the other has the shape of a pick.
01:42:32 Put your finger on the teeth
01:42:34 of a plastic comb.
01:42:36 It's the same principle.
01:42:38 The sound emitted by the ancient crickets
01:42:40 was very different from that
01:42:42 of the modern insects,
01:42:44 which were much louder.
01:42:46 The sound emitted was more like a whistle.
01:42:48 With high-frequency waves,
01:42:50 it could also communicate secretly,
01:42:52 as if it were on a secure radio channel.
01:42:54 If you heard that,
01:42:56 you would probably have trouble sleeping.
01:42:58 Today, our crickets are less noisy,
01:43:00 because they use more high frequencies.
01:43:02 The higher-frequency waves
01:43:04 propagate less far,
01:43:06 which reduces the risk
01:43:08 that a bat might hear them.
01:43:10 Imagine the noise of the jungle at this time.
01:43:12 The powerful crickets' gas
01:43:14 hurts your ears.
01:43:16 Then you hear the whistle of a brachiosaur.
01:43:18 The clacking of a pterodactyl's beak
01:43:20 makes the sound of a thunderbolt.
01:43:22 Then you hear the sound of trumpets
01:43:24 somewhere in the jungle.
01:43:26 These are parasaurolophus
01:43:28 that communicate with each other.
01:43:30 And then you are scared by the siren of a tyrannosaur.
01:43:32 It's impossible to find peace
01:43:34 in such conditions.
01:43:36 Fortunately, humans appeared
01:43:38 several million years later.
01:43:40 Scientists have also
01:43:42 discovered what the sound
01:43:44 of our ancestors sounded like.
01:43:46 They carefully examined the position
01:43:48 of the mouth, nose and throat
01:43:50 on the skeleton of the Neanderthal man.
01:43:52 His voice was similar to ours,
01:43:54 but the phonetic range of an adult
01:43:56 was the same as that of two or three years old.
01:43:58 A kind of mumbling
01:44:00 without consonants.
01:44:02 The skull's sound did not allow
01:44:04 to recreate precisely the voice of Neanderthals,
01:44:06 but in 2007, scientists
01:44:08 extracted DNA samples
01:44:10 from their bones.
01:44:12 They found a variation of the gene
01:44:14 corresponding to human speech.
01:44:16 Scientists think that Neanderthals
01:44:18 fought with Homo sapiens.
01:44:20 Following this conflict,
01:44:22 their species went extinct.
01:44:24 But the gene discovered indicates
01:44:26 that they could also have other links between them.
01:44:28 Maybe Neanderthals could understand
01:44:30 other languages and even pronounce certain words.
01:44:32 The Ligre is probably
01:44:40 the most popular hybrid animal,
01:44:42 and an incredibly large cat.
01:44:44 You will not find it in nature.
01:44:46 This crossbreeding is most often
01:44:48 done in a deliberate way.
01:44:50 Lions and tigers do not live in the same regions.
01:44:52 The Ligre is a crossbreeding
01:44:54 between a lion and a tigress,
01:44:56 and it can become very large
01:44:58 in a very short time.
01:45:00 These are actually
01:45:02 the largest cats in the world.
01:45:04 Hercules, the largest Ligre known,
01:45:06 is a concrete example.
01:45:08 418 kg and 3.30 m long.
01:45:10 Imagine taking it for a walk.
01:45:14 Ligres are generally
01:45:16 much larger than their parents.
01:45:18 In most cases, they behave
01:45:20 and look more like lions than tigers.
01:45:22 But they also have some
01:45:24 features of a tiger.
01:45:26 For example, they have a striped back
01:45:28 and love to swim.
01:45:30 And now, the tiger.
01:45:32 No one could blame you for thinking
01:45:34 that the tiger and the Ligre are
01:45:36 basically the same animal.
01:45:38 After all, they are both a combination
01:45:40 of tigers and lions.
01:45:42 But the tiger is from the crossbreeding
01:45:44 of a tiger and a lioness.
01:45:46 It is generally more tame than its parents
01:45:48 and much smaller than its giant cousin.
01:45:50 Can we call them cousins?
01:45:52 In most cases,
01:45:54 tigers have a charming look
01:45:56 like their tiger father.
01:45:58 But they also have some interesting features
01:46:00 like their mother.
01:46:02 For example, their socialization
01:46:04 and their ability to roar.
01:46:06 One of the rarest hybrid animals
01:46:08 in the world is the dolphin.
01:46:10 It is from a crossbreeding
01:46:12 between a female great dolphin
01:46:14 and a male false orc.
01:46:16 Its name can be confusing,
01:46:18 but the false orc belongs to the dolphin family.
01:46:20 And it is not even related to the orcs.
01:46:22 The dolphins are a very interesting example
01:46:24 of a 50/50 mix of their two parents.
01:46:26 They have dark grey skin,
01:46:28 which is the perfect mix
01:46:30 between a black false orc
01:46:32 and a light grey dolphin.
01:46:34 Dolphins have between 80 and 100 teeth,
01:46:36 false orcs have 44.
01:46:38 And their little hybrid
01:46:40 is halfway there with 66 teeth.
01:46:42 What would a crossbreeding
01:46:44 between an eagle and a lemur look like?
01:46:46 No need to imagine,
01:46:48 the result exists
01:46:50 and it is a sea lemur.
01:46:52 It lives in the salt marshes of Canada
01:46:54 and New England
01:46:56 and it is probably the weirdest hybrid
01:46:58 you will see in this video,
01:47:00 or even in the world.
01:47:02 Half plant, half animal.
01:47:04 Some lemurs seem to have had the good idea
01:47:06 to take genes from innocent algae
01:47:08 that they fed on,
01:47:10 which explains the similarity.
01:47:12 As they are partially plants themselves,
01:47:14 they can produce the plant pigment
01:47:16 called chlorophyll.
01:47:18 This means that these unusual lemurs
01:47:20 are even capable of photosynthesis.
01:47:22 It is the process used by plants
01:47:24 to transform sunlight into energy.
01:47:26 Thus, they produce their own molecules
01:47:28 that contain energy
01:47:30 without having to eat anything.
01:47:32 When scientists discovered it,
01:47:34 the sea lemur was the first case
01:47:36 of a multicellular animal
01:47:38 capable of producing chlorophyll.
01:47:40 What do you get
01:47:42 if you mix a leopard and a lion?
01:47:44 Another interesting hybrid,
01:47:46 the leopard.
01:47:48 These animals are almost as big as lions,
01:47:50 but they have shorter legs
01:47:52 like their father, the leopard.
01:47:54 They also inherit some of these traits,
01:47:56 such as the passion for climbing
01:47:58 and swimming.
01:48:00 There can also be a union
01:48:02 between a lion and a female leopard,
01:48:04 and the result is called a lipar.
01:48:06 Male lions generally measure
01:48:08 about 3 meters long
01:48:10 and weigh about 230 kg.
01:48:12 The female leopard is much more feminine
01:48:14 and weighs about 36 kg.
01:48:16 The difference in size is so significant
01:48:18 that this union is not so frequent.
01:48:20 Now,
01:48:22 why not a bison with a cow?
01:48:24 When you were a kid,
01:48:26 you might have thought
01:48:28 they could do the housework,
01:48:30 but in reality, this combination
01:48:32 creates an unusual hybrid animal
01:48:34 called the bifalo.
01:48:36 Few hybrid animals can reproduce,
01:48:38 but the bifalo can.
01:48:40 When a grizzly and a polar bear mate,
01:48:42 it gives a bear called a groler
01:48:44 or a pizli,
01:48:46 or a grizzlar,
01:48:48 choose the one you prefer.
01:48:50 You can even see them in nature.
01:48:52 These two types of bears
01:48:54 are usually mutually disliked,
01:48:56 and they are not gifted
01:48:58 to live together in a common habitat.
01:49:00 But even if it's rare,
01:49:02 love can strike anywhere
01:49:04 and give birth to these adorable
01:49:06 caramel-colored hybrids.
01:49:08 In most cases,
01:49:10 they are 1.5 meters tall,
01:49:12 and weigh about 455 kilos.
01:49:14 But they are well equipped
01:49:16 to survive in warmer climates
01:49:18 thanks to the genes
01:49:20 they received from their grizzly family.
01:49:22 Now let's move on to a rather tough animal,
01:49:24 the jaglion.
01:49:26 As its name suggests,
01:49:28 it's a hybrid from the cross between
01:49:30 a jaguar and a lion.
01:49:32 We don't know much about these
01:49:34 big, intriguing felines,
01:49:36 because there are only a few specimens.
01:49:38 But the black jaguar and the lion
01:49:40 eventually gave birth to two little jaglions.
01:49:42 One had a dark grey coat
01:49:44 with black spots,
01:49:46 due to the dominant gene of melanin
01:49:48 that black jaguars usually have.
01:49:50 The other had a lion's color
01:49:52 and jaguar's rosette-shaped spots.
01:49:54 You guessed it,
01:49:58 there is also the liguard,
01:50:00 a hybrid between a female jaguar
01:50:02 and a male lion.
01:50:04 Speaking of wild cats,
01:50:06 have you ever heard of savannah cats?
01:50:08 They belong to both the category
01:50:10 of domestic animals
01:50:12 and that of exotic hybrids,
01:50:14 as they are the mix of a domestic cat
01:50:16 and a type of hybrid African serval.
01:50:18 We are talking about an amazing animal here,
01:50:20 almost the size of a domestic cat.
01:50:22 But what gives it its exotic aspect
01:50:24 are its long body,
01:50:26 its elongated shapes,
01:50:28 and its plush fur.
01:50:30 These cats are extremely loyal,
01:50:32 intelligent and affectionate creatures.
01:50:34 They are a mix of all kinds,
01:50:36 a zebroid.
01:50:38 Technically, it is the name
01:50:40 used to describe a hybrid
01:50:42 from a zebra and any other species.
01:50:44 But if you pair a zebra with a female,
01:50:46 their little ones are called a zebra.
01:50:48 Zebra hybrids usually look like
01:50:50 the animal they have been crossed with,
01:50:52 but with the striped fur of a pure zebra.
01:50:54 Most of these hybrid creatures
01:50:56 do not have a striped fur.
01:50:58 There are stripes,
01:51:00 especially on the non-white areas
01:51:02 of their body and paws.
01:51:04 Speaking of zebra hybrids,
01:51:06 look at this adorable creature.
01:51:08 It is called a zebra.
01:51:10 It is usually fawn-colored,
01:51:12 gray or brown.
01:51:14 It is distinguished by its unique stripes
01:51:16 that are darker on its paws and belly.
01:51:18 Unlike some hybrids like the lyre,
01:51:20 zebras can normally live in the wild.
01:51:22 This is where we meet them,
01:51:24 living their lives in the savannah
01:51:26 and in the bush,
01:51:28 mainly in Africa.
01:51:30 Can you guess what a fawn is?
01:51:32 Yes, it is a combination of a goat
01:51:34 and a sheep.
01:51:36 It is certainly one of the most adorable
01:51:38 hybrid creatures in this video.
01:51:40 Fawns are very rare.
01:51:42 Some experts even think
01:51:44 that it is possible that they are not
01:51:46 real hybrids, but simply sheep
01:51:48 with some genetic anomalies.
01:51:50 After all, sheep and goats
01:51:52 carry a different number of chromosomes,
01:51:54 which means that the mixtures between
01:51:56 species are almost impossible.
01:51:58 When a sheep and a llama
01:52:00 mate, they get a cute little thing
01:52:02 called a kama.
01:52:04 Similar to the bifalo,
01:52:06 the kama is the best of its two parents.
01:52:08 The first kama was born in 1998.
01:52:10 Kamas have no bones,
01:52:12 their body is covered
01:52:14 with a soft and soft fur,
01:52:16 similar to that of the llama.
01:52:18 They can drink a lot of water at once,
01:52:20 which allows them to survive
01:52:22 without water for a very long time.
01:52:26 The coyote and the wolf
01:52:28 are not so unusual for most people,
01:52:30 since the coyote and the wolf
01:52:32 do not look so radically different.
01:52:34 After all,
01:52:36 these two species diverged
01:52:38 about 200,000 years ago.
01:52:40 Today, they are still able
01:52:42 to mate and give birth to coyotes.
01:52:44 People living in eastern Canada
01:52:46 and the United States
01:52:48 may know these intelligent
01:52:50 and adaptable animals that populate
01:52:52 their forests, parks and neighborhoods,
01:52:54 and sometimes even their cities.
01:52:56 These hybrids appeared around the last century,
01:52:58 and they took on the characteristics
01:53:00 of their two parents.
01:53:02 When a coyote is an adult,
01:53:04 it is an intermediate size
01:53:06 between those of its two parents.
01:53:08 But it also weighs 25 kilos more
01:53:10 than pure coyotes and has a larger jaw,
01:53:12 longer legs, smaller ears
01:53:14 and a more chubby tail.
01:53:16 Here is now the narluga,
01:53:18 an extremely rare creature
01:53:20 from the cross between a narwhal
01:53:22 and a beluga.
01:53:24 It is a rather strange animal,
01:53:26 but far from being solitary,
01:53:28 which lives mainly in the North Atlantic.
01:53:30 Scientists have been suspecting
01:53:32 its existence for decades.
01:53:34 In 1990, they found a whale skull
01:53:36 that looked unusual
01:53:38 in the tool shed of an Inuit hunter
01:53:40 in Greenland.
01:53:42 People in this region said
01:53:44 that there were other similar-looking animals
01:53:46 and that they did not correspond
01:53:48 to the description of a beluga
01:53:50 but to the description of a narwhal
01:53:52 and similar fins to that of a beluga.
01:53:54 Narwhals and belugas have a similar size
01:53:56 and share the same family,
01:53:58 that of mono-dentidae.
01:54:00 It may therefore not be surprising
01:54:02 that they can reproduce successfully
01:54:04 in nature.
01:54:06 Despite their cold blood,
01:54:10 crocodiles and alligators
01:54:12 are among the most attentive
01:54:14 and sweetest parents in the animal world.
01:54:16 Seriously, yeah!
01:54:18 The females of these frightening animals
01:54:20 lay from 10 to 60 eggs at a time,
01:54:22 which they then bury in nests
01:54:24 on the river bank.
01:54:26 They build these nests with plants
01:54:28 that they tear with their teeth
01:54:30 and grow together with their hind legs.
01:54:32 Then, the crocodile mothers
01:54:34 patiently wait for a period
01:54:36 of up to 3 months,
01:54:38 protecting their future baby from any danger.
01:54:40 Although crocodiles are themselves
01:54:42 animals as powerful as frightening,
01:54:44 they do not hesitate to request special babysitters
01:54:46 to protect their nests.
01:54:48 The eggs of Ichnem are vermiculated.
01:54:50 It may seem quite risky,
01:54:52 but these birds have formed a mutually beneficial alliance
01:54:54 with the crocodiles.
01:54:56 They place their eggs nearby
01:54:58 and together they make the big reptiles flee,
01:55:00 such as the varans of an island
01:55:02 and other predators.
01:55:04 Crocodiles have an excellent nest.
01:55:06 The cries of the birds warn the mother
01:55:08 of all unwanted guests.
01:55:10 And the crocodile mother comes out of the water
01:55:12 to protect her babies and the bird nests
01:55:14 from predators.
01:55:16 When baby crocodiles are born,
01:55:18 they are the size of a big banana
01:55:20 and it takes them years to reach maturity,
01:55:22 from 4 to 15 years, depending on the species.
01:55:24 In some cases, a female crocodile
01:55:26 helps her babies hatch
01:55:28 by putting the eggs in her mouth
01:55:30 and making them roll.
01:55:32 Crocodile babies tend to stay together
01:55:34 near their mother for the first three years of their lives.
01:55:36 The mother helps her children get out of the nest
01:55:38 and transports them to the water in her mouth.
01:55:40 A female crocodile can put up to 15 babies
01:55:42 in her mouth at the same time
01:55:44 and instinct prevents her from
01:55:46 dropping her jaws.
01:55:48 Thus, the newly hatched babies feel safe
01:55:50 in the crocodile's mouth as if it were
01:55:52 a cradle. A very toothy cradle.
01:55:54 Although the crocodile teaches
01:55:56 its young to hunt
01:55:58 and protects them from predators,
01:56:00 only about 1% of the young survive
01:56:02 until adulthood, due to predators
01:56:04 and climatic conditions.
01:56:06 Sad news for all parents,
01:56:08 but crocodiles are cold-blooded reptiles
01:56:10 and cold-blooded, after all.
01:56:12 The only reason why they cry
01:56:14 is physiological rather than emotional.
01:56:16 When crocodiles spend enough time
01:56:18 out of the water, their eyes become
01:56:20 so dry that they cry to keep them moist.
01:56:22 If a baby crocodile manages to survive
01:56:24 its childhood, it has the chance
01:56:26 to live a very long life.
01:56:28 Just like other reptiles, turtles and whales,
01:56:30 crocodiles show what is called
01:56:32 a negligible senescence,
01:56:34 or in simple terms,
01:56:36 a lack of normal aging.
01:56:38 They don't really age,
01:56:40 but they become bigger and meaner.
01:56:42 They are only afraid of getting sick
01:56:44 or being attacked by other predators.
01:56:46 Although the average life span of crocodiles
01:56:48 varies from 50 to 70 years,
01:56:50 some of them reach more than 100 years.
01:56:52 So, in theory,
01:56:54 someone could meet a 500-year-old crocodile
01:56:56 as huge as a plane
01:56:58 somewhere in the depths of the tropics.
01:57:00 But his chances of surviving
01:57:02 and of making it to this meeting are rather slim,
01:57:04 because the crocodile's appetite
01:57:06 is proportional to its body.
01:57:08 Mr. Freshie, who died at the age of 140,
01:57:10 was the oldest crocodile
01:57:12 studied in captivity.
01:57:14 He was captured in the Moorhead River
01:57:16 in 1970
01:57:18 and lived in the Australia Zoo
01:57:20 in Queensland.
01:57:22 Mr. Freddy bore the name of his species,
01:57:24 the freshwater crocodile,
01:57:26 a breed that was never known
01:57:28 to be taken by humans.
01:57:30 At the age of 10, when crocodiles reach
01:57:32 a body length of about 1.5 to 3 meters,
01:57:34 they become mature enough
01:57:36 to give birth to their own baby.
01:57:38 The mating dance involves
01:57:40 several stages.
01:57:42 Males produce a low-frequency special sound
01:57:44 that humans cannot perceive.
01:57:46 But for female crocodiles,
01:57:48 this sound is like an invitation to become a mother
01:57:50 and to perpetuate the sweet parental tradition.
01:57:52 Of course,
01:57:54 crocodiles are not the only animals
01:57:56 to show remarkable dedication
01:57:58 and family value.
01:58:00 Polar bears, for example,
01:58:02 are very devoted and take their time
01:58:04 to teach their young all the techniques
01:58:06 of survival necessary in a cold climate.
01:58:08 When babies are still in their mother's womb,
01:58:10 polar bears create a special space
01:58:12 by digging deep into the conger.
01:58:14 This space is used as a house
01:58:16 for future bears.
01:58:18 They spend the first months of their lives
01:58:20 receiving milk and the warmth of their mother.
01:58:22 Polar bears usually lay eggs
01:58:24 between November and January
01:58:26 and do not let the bears out before spring.
01:58:28 The fur of newborns is very thin
01:58:30 and they are not yet ready to face the cold.
01:58:32 Once the bears are out of their conger,
01:58:34 the mother bear begins to teach them
01:58:36 how to survive in the outside world.
01:58:38 Babies imitate all these movements,
01:58:40 learn to swim, to hunt,
01:58:42 to dig congers and to migrate.
01:58:44 The mother bears fight the predators
01:58:46 and the larger polar bears
01:58:48 and hide these bears from any threat.
01:58:50 After two or three years of living together,
01:58:52 the young have learned everything they needed to know
01:58:54 and leave their mother.
01:58:56 They will be able to recognize her
01:58:58 throughout their lives,
01:59:00 on average, 30 years old.
01:59:02 Another example of careful motherhood
01:59:04 can be observed in our relatives,
01:59:06 the primates.
01:59:08 Gorillas, chimpanzees and their cousin Bonobo
01:59:10 cuddle and kiss their newborns
01:59:12 just like humans.
01:59:14 By feeding their young,
01:59:16 female primates release special hormones
01:59:18 associated with maternal and sweet feelings.
01:59:20 In terms of breastfeeding,
01:59:22 orang-utans are the champions.
01:59:24 This process can last up to 8 years.
01:59:26 Of course, orang-utans mothers
01:59:28 breastfeed their offspring longer
01:59:30 than any other primate.
01:59:32 During this period, mothers teach their young
01:59:34 to find food and to build
01:59:36 their own nests to sleep.
01:59:38 The link between female orang-utans
01:59:40 and their mothers is stronger than that of males.
01:59:42 Girls can continue to live with their mothers
01:59:44 until they reach the age of procreation,
01:59:46 either 15 or 16 years old.
01:59:48 And yes, they have no desire to leave their cocoons.
01:59:50 Just like humans,
01:59:52 monkeys can have complex relationships
01:59:54 with their mothers,
01:59:56 which have an impact on their social life.
01:59:58 Maternal support helps young primates
02:00:00 to acquire a certain dominance
02:00:02 and to perpetuate the cycle of reproduction
02:00:04 when they grow up.
02:00:06 On the contrary, monkeys that have not received
02:00:08 enough maternal care in their childhood
02:00:10 tend to have fewer children
02:00:12 when they reach maturity.
02:00:14 Moreover, African males elephants
02:00:16 do not fight for dominance
02:00:18 because all important issues are resolved by females.
02:00:20 And each elephant of the herd
02:00:22 is equally supported by all the others.
02:00:24 A young female elephant
02:00:26 receives help from her older sisters and aunts
02:00:28 to put her young down and raise her young.
02:00:30 This is why the elephant is considered
02:00:32 as one of the most protective mothers on the planet.
02:00:34 The herds of female elephants
02:00:36 and their elephants
02:00:38 tend to travel together in a particular circle.
02:00:40 The youngest members of the group
02:00:42 are placed inside the circle
02:00:44 to protect them from predators.
02:00:46 Also, the older elephants
02:00:48 adjust the rhythm of the herd
02:00:50 so that the elephants do not get tired
02:00:52 and do not stay in the circle.
02:00:54 The females of the group communicate with the babies
02:00:56 by affectionate gestures
02:00:58 and teach them to find food.
02:01:00 Moreover, the little elephants
02:01:02 are very attached to their mother
02:01:04 and generally stay together
02:01:06 until she dies of old age.
02:01:08 And the average life expectancy of elephants
02:01:10 is about 65 years or more.
02:01:12 Mothers carry their young for two years.
02:01:14 It is therefore not surprising
02:01:16 that they are so attached to each other.
02:01:18 Elephants generally have a long gestation period
02:01:20 of 15 months.
02:01:22 But this is quite justified
02:01:24 because the baby giraffe
02:01:26 is already standing very little time after its birth.
02:01:28 The mother helps the baby giraffes
02:01:30 for about 9 to 12 months.
02:01:32 When she has to go get food,
02:01:34 she hides her babies
02:01:36 or asks other giraffes to take care of them.
02:01:38 Like humans, giraffe mothers
02:01:40 must stay awake.
02:01:42 They can sleep from 30 minutes
02:01:44 to a few hours a day.
02:01:46 The time they have to sleep
02:01:48 is extremely short,
02:01:50 5 to 10 minutes at a time.
02:01:52 The rest of the time is dedicated
02:01:54 to the care and protection of the babies.
02:01:56 The mothers do not fear
02:01:58 the difficulties either.
02:02:00 After laying an egg,
02:02:02 the female entrusts it to a male
02:02:04 who protects it from any threat.
02:02:06 During this time,
02:02:08 the mother takes a long journey
02:02:10 reaching up to 80 km
02:02:12 to reach the edge of the ocean
02:02:14 to give the fish to her little ones
02:02:16 that come from the corals.
02:02:18 Using the heat of her own body,
02:02:20 the female penguin keeps
02:02:22 the young generation warm and safe.
02:02:24 you
