00:00:00Welcome, dear guests, and welcome to the Saint Aquarium.

00:00:04Here, you will be able to admire the most dangerous marine and oceanic creatures,

00:00:08but do not let yourself be misled by what I said.

00:00:10It is highly possible that you met one of these underwater creatures

00:00:13during a banal walk on the beach.

00:00:16So look at them carefully right now, and you could avoid the worst.

00:00:22Is it a fish or an old rock?

00:00:25What you are observing is commonly called the stone fish,

00:00:28or, if not, for the faint of heart.

00:00:32If you like diving and observing the seabed,

00:00:35you may have already met one, without even noticing it.

00:00:38Its appearance makes it almost impossible to distinguish it from any other stone,

00:00:42due to its gray coloration and its sharp appearance.

00:00:46Especially if your diving glasses are a little fogged up.

00:00:49Finally, you would better be careful,

00:00:51because otherwise the consequences could be devastating,

00:00:54since stone fish are among the most venomous there are.

00:00:58Although certain types of stone fish are known to live in rivers,

00:01:01most of them live in coral reefs near the tropics of the Pacific and Indian Oceans.

00:01:06The spines of their dorsal fins, in the shape of needles,

00:01:09stand up when they feel disturbed or threatened,

00:01:12and inject the poison they contain.

00:01:14The most common reason for stone fish bites

00:01:16is that swimmers walk on them without realizing it.

00:01:19However, it is not necessary to be in the water to be bitten.

00:01:22As they can survive out of the water for up to 24 hours,

00:01:25you should also be careful where you walk when you go to the beach.

00:01:28People who have been bitten by stone fish

00:01:31describe it as an extremely painful experience.

00:01:34This venom can cause infections,

00:01:36and in some cases it is known to have resulted in a state of shock,

00:01:39or even a paralysis.

00:01:41This may seem surprising, but despite its bad reputation,

00:01:44the stone fish is quite edible if it is properly prepared.

00:01:48When the fish is cooked, its venom decomposes,

00:01:51and if its dorsal fins, which are the main source of its venom, are removed,

00:01:54the raw stone fish can also be served as sashimi.

00:01:59This creature may look like it came out of a sci-fi movie,

00:02:02but it is very real.

00:02:04Say hello to the blue-tailed octopus.

00:02:07Don't be fooled by its small size,

00:02:09which can go from 12 to 20 cm,

00:02:11counting the tentacles,

00:02:13because these little creatures are full of venom,

00:02:15capable of affecting up to 26 people in a few minutes.

00:02:19Just like stone fish,

00:02:21the blue-tailed octopus is found in the Pacific and Indian Oceans,

00:02:25from Japan to Australia.

00:02:28They generally live in the coral reefs

00:02:30and rocky areas at the bottom of the seas.

00:02:32They can also be found in residual marshes,

00:02:34marine herbivores and lidalgos.

00:02:37Blue-tailed octopuses are not aggressive by nature.

00:02:40When they are not looking for food,

00:02:42such as crabs and shrimps,

00:02:44or looking for a partner,

00:02:46they often hide in marine reefs,

00:02:48seashells or crevasses.

00:02:50When they are attacked,

00:02:52they become dangerous for humans.

00:02:54When they are threatened,

00:02:56they take a bright yellow color

00:02:58and iridescent blue rings

00:03:00appear on all their bodies

00:03:02as a warning to their potential predators.

00:03:04Their bite is usually unnoticed,

00:03:06so you can't realize you've been stung

00:03:08before it's too late.

00:03:10The venom of a blue-tailed octopus can cause dizziness,

00:03:13as well as a loss of senses and motor skills,

00:03:15and finally paralysis.

00:03:17So it's better to keep your hands to yourself

00:03:19and slow down if you see one.

00:03:23No, it's not a bouquet of flowers,

00:03:25so don't try to pick it up

00:03:27and feel one of its pinkish cubes.

00:03:29What you see is a marine animal

00:03:31called the blue-tailed octopus.

00:03:34It may look beautiful,

00:03:36but don't be fooled by its appearance.

00:03:38It was named the most dangerous

00:03:40in the Guinness Book of Records in 2014.

00:03:42Blue-tailed octopuses live in tropical areas

00:03:44of the Indo-Pacific basin

00:03:46and generally live in coral reefs,

00:03:48rocks, sand, and marine shrubs

00:03:50at depths from 0 to 90 meters.

00:03:55Their most remarkable feature

00:03:57is their pedicellar,

00:03:59which are defensive organs in the shape of claws,

00:04:01which can also be found in sea stars.

00:04:03What sets them apart from all the other sea urchins

00:04:05is the fact that their pedicellar

00:04:07are, as their name suggests, in the shape of flowers,

00:04:09and generally pinkish-white

00:04:11to pale yellowish-white,

00:04:13with a purple central point.

00:04:16Hidden under these flowers,

00:04:18they also have short, mossy spines.

00:04:21Although many sea urchins

00:04:23deliver their venom through these spines,

00:04:25sea urchins do so through their pedicellar,

00:04:27or flowers.

00:04:30If they are not disturbed,

00:04:32the ends of these flowers

00:04:34generally have a rounded,

00:04:36elongated shape.

00:04:38Their surface has tiny sensors

00:04:40with which they can detect danger.

00:04:42And when they come into contact

00:04:44with other sea urchins,

00:04:46they immediately close their eyes

00:04:48and start injecting their venom.

00:04:50What is curious

00:04:52is that the small claws of these flowers

00:04:54can sometimes detach from their spines,

00:04:56cling to the point in contact

00:04:58and continue to inject venom

00:05:00for hours on end.

00:05:02It looks like a giant ice flake

00:05:04with a melted raspberry, doesn't it?

00:05:06You'd like that,

00:05:08except it's a lion's mane jellyfish,

00:05:10also called capillary cyanide.

00:05:14They are known for preferring cold waters,

00:05:16which is why they are found

00:05:18mainly in the Arctic Ocean,

00:05:20North Atlantic and North Pacific.

00:05:22But it is also possible

00:05:24to see them around the British Isles

00:05:26and in the Scandinavian waters.

00:05:28The lion's mane jellyfish

00:05:30is one of the largest known species of jellyfish.

00:05:34They owe their name to their long tentacles,

00:05:36similar to hair,

00:05:38which can reach a length of 3 meters.

00:05:40And although the average diameter

00:05:42of a lion's mane jellyfish

00:05:44is about 50 centimeters,

00:05:46it can sometimes reach a diameter

00:05:48of more than 2 meters.

00:05:50The largest lion's mane jellyfish

00:05:52ever observed was seen in 1865

00:05:54off the coast of Massachusetts.

00:05:56It was estimated to have tentacles

00:05:58about 36 meters long

00:06:00for a diameter of more than 2 meters.

00:06:02To give you an idea of its size,

00:06:04it was longer than a blue whale.

00:06:06Lion's mane jellyfish

00:06:08hunt by spreading their tentacles

00:06:10all around, creating a trap

00:06:12to catch their food.

00:06:14As it has about 1,200

00:06:16stinging tentacles,

00:06:18it would take an extremely lucky fish

00:06:20to hope to escape them.

00:06:22The sting of a lion's mane jellyfish

00:06:24generally does not present

00:06:26a deadly danger,

00:06:28but you still have to avoid

00:06:30swimming through its tentacles

00:06:32because it can be very painful

00:06:34for humans.

00:06:36And if you send a fall on the beach,

00:06:38it can be very dangerous.

00:06:40Fun fact, the lion's mane jellyfish

00:06:42appears in the story of Sherlock Holmes

00:06:44The Lion's Mane as a suspect.

00:06:46But don't worry,

00:06:48we won't give any spoilers.

00:06:50The last marine animal you see

00:06:52is a sea snake.

00:06:54Yes, they are different from eels.

00:06:56There are 69 species

00:06:58identified as sea snakes.

00:07:00Most of them are found

00:07:02in the tropical and subtropical waters

00:07:04of the Indian and Pacific Oceans.

00:07:06And they have existed for millions of years.

00:07:08To make things easier,

00:07:10scientists have separated

00:07:12all the different species of sea snakes

00:07:14into two categories.

00:07:16The real sea snakes

00:07:18and the striped ones.

00:07:20While the real sea snakes

00:07:22spend almost all their time at sea,

00:07:24the striped ones can also crawl on the ground.

00:07:26If you see a snake on the beach,

00:07:28you can determine

00:07:30whether it is a sea snake

00:07:32by looking at its tail.

00:07:34If it doesn't look like a striped one,

00:07:36then it is a sea snake.

00:07:38But keep your distance in both cases.

00:07:40All sea snakes must surf

00:07:42regularly to breathe

00:07:44because they don't have branches.

00:07:46That's why you can meet one

00:07:48while you're swimming.

00:07:50If that happens,

00:07:52you'd better get away

00:07:54as soon as possible

00:07:56because most sea snakes

00:07:58have more venom

00:08:00than a cobra or a medium crotal.

00:08:02Most sea snakes

00:08:04are the only reptiles

00:08:06to give birth in the ocean.

00:08:08Most sea snakes

00:08:10keep their eggs in a nest

00:08:12and give birth

00:08:14to small snakes

00:08:16almost already formed

00:08:18while they're still alive.

00:08:20But that's not the case

00:08:22with the striped one.

00:08:24It crawls on the ground

00:08:26to lay its eggs.

00:08:28Do you remember the stone fish

00:08:30we saw earlier?

00:08:32It's not a problem

00:08:34because of the way

00:08:36the light propagates.

00:08:38The light produced by the sun

00:08:40is white.

00:08:42When it passes through a prism,

00:08:44we see light waves

00:08:46of different colours,

00:08:48from red to orange,

00:08:50blue, green and indigo.

00:08:52The light travels in a straight line

00:08:54without obstacles.

00:08:56The shortest light waves,

00:08:58like molecules and aerosols

00:09:00present in the atmosphere,

00:09:02are dispersed.

00:09:04As the sun is low

00:09:06on the horizon at sunset

00:09:08and sunrise,

00:09:10its light must travel

00:09:12through more molecules

00:09:14that disperse violet and blue light.

00:09:16The colours you see

00:09:18are yellow, orange and red.

00:09:20But in good conditions,

00:09:22you can see a beautiful purple sky.

00:09:24Sometimes, a purple sky

00:09:26is even more harmful.

00:09:28It can be caused by hurricanes,

00:09:30forest fires or dust storms.

00:09:32The concentration of steam in the air

00:09:34increases and the light

00:09:36disperses more than usual.

00:09:38Dust, sunset and low clouds

00:09:40also contribute to this natural spectacle.

00:09:42The sky turns orange and red

00:09:44at dusk

00:09:46if there is still enough light.

00:09:48Then it emits pink tones

00:09:50that mix with the dark blue of the sky.

00:09:52Do you remember what happens

00:09:54when you mix purple and blue?

00:09:56You get purple.

00:09:58All hurricanes do not

00:10:00make the sky turn purple.

00:10:02And trying to predict

00:10:04if this will happen

00:10:06is like trying to predict

00:10:08a rainbow.

00:10:10However, people have reported

00:10:12that several major hurricanes

00:10:14had so close to the sky.

00:10:16A green sky can seem

00:10:18just as spectacular as purple,

00:10:20but it is also synonymous with danger.

00:10:22The unique color results

00:10:24from the mixture of yellow rays

00:10:26of the sun and the blue light

00:10:28of the storm clouds.

00:10:30You enjoy a beautiful day

00:10:32by the sea with a cool breeze

00:10:34in your hair when suddenly

00:10:36you notice that the water

00:10:38begins to withdraw from the beach

00:10:40at full speed.

00:10:42This is the forerunner sign

00:10:44that you must flee as quickly

00:10:46and as far as possible from the beach

00:10:48because this probably means

00:10:50a tsunami.

00:10:52If you notice that the sea level

00:10:54rises, but without it

00:10:56seeming too extreme,

00:10:58it may be another sign

00:11:00of the approach of a tsunami.

00:11:02This happens in 40% of cases

00:11:04and this flood is only

00:11:06the first wave of this tidal wave.

00:11:08The next, much more

00:11:10consequent and dangerous,

00:11:12usually follows in 10 minutes.

00:11:14Another feature of tsunamis

00:11:16is that they are accompanied

00:11:18by strong waves

00:11:20or simply by a powerful

00:11:22deflagration.

00:11:24You see a channel of agitated water

00:11:26on the beach.

00:11:28It is in your interest

00:11:30not to approach the water.

00:11:32There may be a current

00:11:34of rippling under the surface

00:11:36that can be extremely dangerous.

00:11:38Sometimes the waves hit

00:11:40the shore in an unusual way,

00:11:42which forms rippling currents.

00:11:44You can then observe

00:11:46another characteristic sign

00:11:48of these rippling currents.

00:11:50If you find yourself caught

00:11:52in such a phenomenon,

00:11:54try to continue to float,

00:11:56but do not try to go against the current.

00:11:58You would only waste precious energy.

00:12:00Call for help and try

00:12:02to float along the shore.

00:12:04Once you are out of the current,

00:12:06swim diagonally towards the beach.

00:12:08The next time you see

00:12:10conical-shaped clouds in the sky,

00:12:12remember that this is the right time

00:12:14to start looking for shelter.

00:12:16If they appear like this,

00:12:18a violent storm is on its way.

00:12:20But if a cloud of this shape

00:12:22begins to spin on itself,

00:12:24it means that it is about

00:12:26to turn into a tornado.

00:12:28If bees are nearby,

00:12:30they can alert you

00:12:32to such a cataclysm.

00:12:34These working little animals

00:12:36become more active than usual

00:12:38when they feel a storm

00:12:40is approaching.

00:12:42And once they have finished,

00:12:44they always come back to the shore

00:12:4610 to 15 minutes before a heavy rain,

00:12:48even if there are

00:12:50no obvious signs of its arrival.

00:12:52Their secret?

00:12:54Super-sensitive hairs on their backs

00:12:56that can detect the electrostatic accumulations

00:12:58of storm clouds.

00:13:00For centuries and centuries,

00:13:02people have noticed that animals

00:13:04behaved strangely a few days

00:13:06before a big earthquake.

00:13:08Dogs keep barking,

00:13:10cows stop producing milk,

00:13:12and toads, rats and snakes

00:13:14desert their habitats.

00:13:16It seems that animals can feel

00:13:18the first shock waves

00:13:20weaker than humans do not even notice.

00:13:22Scientists have tried to find

00:13:24a logical explanation for this phenomenon

00:13:26and have conducted countless experiments.

00:13:28So far, they have not yet

00:13:30managed to fully explain

00:13:32this mystery.

00:13:34Can you smell ozone in the air?

00:13:36When a storm is preparing,

00:13:38you can smell it.

00:13:40It is the electric charge of the lightning

00:13:42that releases it at an altitude.

00:13:44The other smell of the rain,

00:13:46more pleasant, is petrichor.

00:13:48Rainwater exalts the molecules

00:13:50of plants, trees, concrete and asphalt.

00:13:52Their aroma spreads everywhere

00:13:54and you can even smell it

00:13:56in your mouth.

00:13:58All the positive ions present in the air

00:14:00and released by lightning

00:14:02mix with ozone and saliva.

00:14:04This is how you get this metallic taste.

00:14:06When lightning is about to strike,

00:14:08you can hear cracks,

00:14:10rumbles or strange vibrations

00:14:12coming from metal objects

00:14:14located nearby.

00:14:16Your hands may start to sweat

00:14:18and finally, you can feel your hair

00:14:20standing on your head.

00:14:22It is a very clear sign that it is time to react

00:14:24and it consists of fleeing

00:14:26to save your life.

00:14:28Positive charges then cross your body

00:14:30trying to reach the negatively charged part

00:14:32of the storm.

00:14:34For me, you really don't want

00:14:36these charges to meet.

00:14:38If you don't see any shelter

00:14:40that you can reach quickly,

00:14:42try to make yourself smaller

00:14:44than the objects around you.

00:14:46Lower your umbrella and stay away

00:14:48from iron wire fences, pipes, rails

00:14:50and any other metallic object.

00:14:52Do not lie on the ground, however.

00:14:54It is probably wet,

00:14:56which means it is an excellent

00:14:58conductor of electricity.

00:15:00If you suddenly notice crevasses

00:15:02around your house,

00:15:04it could be a forerunner

00:15:06of a landslide.

00:15:08Inspect your house from the inside.

00:15:10Does the door start to get stuck?

00:15:12Or maybe there is a space

00:15:14between the walls and the ceiling.

00:15:16Illegal cupboards and kitchen drawers,

00:15:18tilted floors, stairs that start to tilt,

00:15:20infiltrations after each rain

00:15:22and moldings moving

00:15:24are as many signs as a valley

00:15:26is about to open.

00:15:28To know if it is really a landslide

00:15:30or a danger,

00:15:32call a geotechnical engineering

00:15:34office.

00:15:36If you come across a pre-existing valley,

00:15:38you must stay away from the area.

00:15:40Install a fence or a rope

00:15:42to make it less dangerous for passers-by.

00:15:44Finally, you will need the help

00:15:46of a professional to fill it.

00:15:48Some volcanoes scream

00:15:50when they are about to erupt.

00:15:52Small earthquakes,

00:15:54which often occur in advance,

00:15:56generate a rumbling.

00:15:58It is not audible to the human ear,

00:16:00but it sometimes reaches a frequency

00:16:02that allows to hear this strange rumbling

00:16:04coming from the ground.

00:16:06This noise is known as harmonic tremor.

00:16:08In the case of some volcanoes,

00:16:10it is the sound of magma bubbles

00:16:12vibrating when they cross

00:16:14the cracks of the earth's crust,

00:16:16but this is not always the case.

00:16:18If scientists were able to understand

00:16:20the exact cause of these volcanic screams,

00:16:22they could create a limited system

00:16:24of pre-alert systems for eruptions.

00:16:26If you are in nature,

00:16:28pay attention to the water of streams,

00:16:30rivers and rivers.

00:16:32If their level drops rapidly

00:16:34when it is raining,

00:16:36it may be a sign of an imminent

00:16:38landslide.

00:16:40And if you hear a slight rumbling

00:16:42or unusual noises,

00:16:44such as rocks colliding,

00:16:46it can mean that debris

00:16:48is already on its way to you.

00:16:50This is obviously a sign

00:16:52that you need to take shelter immediately.

00:16:54You take a rag and a broom

00:16:56to get rid of all these spiderwebs

00:16:58on your windows.

00:17:00They have no chance this time.

00:17:02By removing one spiderweb after the other,

00:17:04you suddenly notice mud

00:17:06with strange shapes stuck

00:17:08under the roof and the porch.

00:17:10What is it?

00:17:12You suddenly realize

00:17:14it must be geckos' nests.

00:17:16With so many nests side by side,

00:17:18there must be a nest.

00:17:20Fortunately, geckos are solitary insects.

00:17:22All these little nests

00:17:24are full of paralyzed spiders.

00:17:26Sometimes up to 500 spiders

00:17:28can be trapped in these nests,

00:17:30waiting for the young geckos to hatch.

00:17:32If the nest has holes,

00:17:34it can indicate that it is old

00:17:36or abandoned,

00:17:38because geckos dig holes to leave their nest.

00:17:40If you want to remove them,

00:17:42it is better to wait until night

00:17:44when they are not so active.

00:17:46Although they are quite placid,

00:17:48if they feel threatened,

00:17:50it looks like an insect was half-designed

00:17:52and then its creator stopped.

00:17:54The toad cricket

00:17:56really seems to come from another world.

00:17:58With toad claws,

00:18:00a cricket body

00:18:02and a shrimp head,

00:18:04this creature is a bit like the insect world's ornithorynx.

00:18:06It is not venomous

00:18:08and only dies

00:18:10if you trap it in your hand.

00:18:12And if you really annoy it,

00:18:14it has another advantage in its sleeve,

00:18:16its wings.

00:18:18It smells bad, just like the fly.

00:18:20So just leave them at home

00:18:22and there will be nothing to clean.

00:18:24The rock basins are full

00:18:26of all kinds of plants and animals.

00:18:28Marine creatures such as

00:18:30starfish, marine herbs,

00:18:32hermit crickets, small fish

00:18:34and all kinds of octopuses.

00:18:36If you think this little octopus has blue eyes,

00:18:38it is better to leave it alone.

00:18:40It blinks in neon blue

00:18:42for a good reason.

00:18:44This miniature octopus has a venomous bite

00:18:46a thousand times stronger than cyanide

00:18:48and no antidote is available.

00:18:50Do not try to tickle it with a stick

00:18:52or pick one up.

00:18:54It is not worth the trip to the hospital

00:18:56or the morgue.

00:18:58Terrestrial snakes may be scary,

00:19:00but marine snakes are on a whole other level.

00:19:02In the Indian and Pacific Oceans,

00:19:04there are about 50 different species

00:19:06of sea snakes

00:19:08and they are as beautiful as dangerous.

00:19:10Fortunately,

00:19:12they don't seem to care too much about us.

00:19:14The sea snake of Dubois

00:19:16is undoubtedly the most venomous in the ocean,

00:19:18nicknamed, so to speak,

00:19:20the beak sea snake.

00:19:22Their venom would almost make you forget

00:19:24the bite of a cobra.

00:19:26The venom of these two snakes

00:19:28is extremely dangerous.

00:19:30Fortunately for us,

00:19:32it can take hours to cause symptoms in humans

00:19:34and it would take them to pierce

00:19:36your diving suit.

00:19:38If this fly lands on your arm outside,

00:19:40you could scream a little,

00:19:42but a scorpion, as its name suggests,

00:19:44has a curved tail that looks like

00:19:46a dart of a scorpion.

00:19:48But you can blow,

00:19:50it is only used for coupling.

00:19:52It also has a long beak-shaped head

00:19:54that is used to feed itself

00:19:56after flying insects

00:19:58in spider webs.

00:20:00To find the ideal partner,

00:20:02it loves to give gifts in the form of saliva,

00:20:04how romantic it is!

00:20:06If you are in Africa,

00:20:08you may pass by this big bird

00:20:10and the sea snake will move

00:20:12when you pass in front of it.

00:20:14Being able to measure up to 1.5 meters

00:20:16and have a wingspan of 2.5 meters,

00:20:18the sea snake looks like a predator,

00:20:20although it is anything but.

00:20:22Known as one of the slowest birds

00:20:24in the world,

00:20:26almost a statue,

00:20:28the sea snake only eats fish

00:20:30near the surface of the water,

00:20:32without worrying about the world.

00:20:34This bird is not at all afraid of humans.

00:20:36Although it is not very talkative,

00:20:38you can take some pictures.

00:20:40If you hear a little squeak

00:20:42while you are in the garden,

00:20:44it could be a mouse,

00:20:46a squirrel or a rhino

00:20:48that tells you that you are too close.

00:20:50They love to make noise

00:20:52when they are disturbed.

00:20:54With their giant and scary horns on their heads,

00:20:56they may seem able to defend themselves,

00:20:58but this is not the case.

00:21:00They only use it to move

00:21:02the leaves and sticks in their path

00:21:04and to prevent other mammals

00:21:06from attacking the female.

00:21:08Not only do they have a horn on their head,

00:21:10but they also have a Herculean strength.

00:21:12They are able to lift

00:21:14their own weight 850 times.

00:21:16It's as if you could lift

00:21:1865 tons

00:21:20or 11 elephants.

00:21:22Living mainly in China,

00:21:24the little sea snake is adorable

00:21:26with its hairy tuft,

00:21:28at least until it turns around

00:21:30and turns out to be a vampire deer.

00:21:32Fortunately, this animal does not

00:21:34eat your blood or wear a cape.

00:21:36Only males grow these attributes

00:21:38rather than woods

00:21:40during the season of love

00:21:42to compete with each other

00:21:44for territories and females.

00:21:46These crows look more like

00:21:48elephant defenses than

00:21:50clenched teeth.

00:21:52Not only do they have crows,

00:21:54but they are also known

00:21:56to bark like dogs

00:21:58and flee like cats

00:22:00when they are afraid.

00:22:02This algae looks a lot like

00:22:04ketchup or rust

00:22:06poured into the water,

00:22:08but it is much worse for the life

00:22:10around it.

00:22:12Fish and marine organisms

00:22:14will try to escape once exposed

00:22:16to the toxic algae present in their water.

00:22:18It is not particularly harmful

00:22:20for humans who are exposed to it,

00:22:22but if you eat seafood contaminated

00:22:24by these toxins,

00:22:26things can get a little worse.

00:22:28So if the sea is red,

00:22:30some spiders like to harbor

00:22:32bright colors to show

00:22:34that they are dangerous,

00:22:36but not the Australian Robustus atrax.

00:22:38This shiny black spider

00:22:40does not need fireworks

00:22:42to prove that it is strong.

00:22:44It can be very dangerous

00:22:46if it decides to bite you.

00:22:48It can stop your nervous system

00:22:50in just 30 minutes.

00:22:52Wearing their web in any shelter,

00:22:54such as old ronds,

00:22:56shoes or even garden dung,

00:22:58they can easily feed themselves.

00:23:00When they have had enough of one place,

00:23:02they leave their web behind

00:23:04and go looking for a new place.

00:23:06Some say that rattlesnakes are intrepid,

00:23:08and in a way they may be right.

00:23:10When you are brave enough

00:23:12to steal food from a jaguar,

00:23:14a lion or a hyena,

00:23:16what are you afraid of?

00:23:18These cousins of the beetle

00:23:20are not only ferocious,

00:23:22they are super smart.

00:23:24They are even known to use tools

00:23:26such as sticks, rocks and mud

00:23:28as climbing objects

00:23:30to regain their freedom.

00:23:32In addition to their physical resemblance

00:23:34to the fly,

00:23:36rattlesnakes have a dangerous gland

00:23:38near their tail

00:23:40that contains a powerful swallowing machine.

00:23:42They are therefore brave,

00:23:44smelly, have an extremely elastic and resistant skin

00:23:46and to top it all off,

00:23:48they enjoy a strong immunity

00:23:50against scorpions and snakes.

00:23:52The best thing to do

00:23:54is to leave it alone.

00:23:56Have you ever heard of the mushroom

00:23:58Hydnel de Peck?

00:24:00No? And its other name,

00:24:02the toothless mushroom?

00:24:04This mushroom is not toxic,

00:24:06but it has such a bitter taste

00:24:08that you should think twice

00:24:10before tasting one.

00:24:12When it is young and in full growth,

00:24:14this white mushroom seems to have red jelly

00:24:16coming out of its pores.

00:24:18This sticky liquid is sap

00:24:20pushed upwards because it has absorbed too much water.

00:24:22The adult mushroom

00:24:24is rather dull compared to this.

00:24:26Under the mushroom's hat,

00:24:28where its pores are produced,

00:24:30there is a structure in the shape of a tooth,

00:24:32as if it were not already quite weird.

00:24:34Tasmanian devils

00:24:36have the reputation of having a very bad temper

00:24:38when they feel threatened by a predator,

00:24:40when they fight with other males

00:24:42or when they are looking for a table for dinner.

00:24:44They are nicknamed devils

00:24:46because of their teeth

00:24:48and one of the most frightening cries

00:24:50they eat almost everything

00:24:52they can find.

00:24:54They are not used to going to people,

00:24:56although they know how to defend themselves

00:24:58if they are threatened.

00:25:00And since their bite is powerful,

00:25:02fortunately the Tasmanian devils

00:25:04prefer to escape.

00:25:06These arid deserts

00:25:08that extend from your point of view

00:25:10seem lifeless.

00:25:12But among these sands,

00:25:14it is also possible to meet dangerous

00:25:16and sometimes frightening creatures.

00:25:18Some may present only a slight risk

00:25:20for our health,

00:25:22but others will remain forever engraved

00:25:24in your memory.

00:25:26Let's get to know them,

00:25:28starting with the most moderately dangerous

00:25:30and ending with the real nightmares.

00:25:32You walk in the desert

00:25:34and you see a big teddy bear,

00:25:36arms wide open.

00:25:38You deduce that it is probably a mirage,

00:25:40but you still approach.

00:25:42You had just seen,

00:25:44it is not a teddy bear,

00:25:46and there is something strange about it.

00:25:48Thanks to its strange pileosity,

00:25:50its branches seem to look like

00:25:52the arms of a teddy bear.

00:25:54However, it is not fur,

00:25:56but thousands of fine needles.

00:25:58And that's why you should not

00:26:00approach it.

00:26:02This cactus is called Cylindro Puntia Bigelowi

00:26:04or Chola Urson.

00:26:06It grows in the desert areas of Arizona

00:26:08and in northern Mexico.

00:26:10Do not worry,

00:26:12this cactus will not attack you as much,

00:26:14but it will approach your skin or your clothes

00:26:16if you have the misfortune to touch it.

00:26:18This fur coat protects the cactus

00:26:20from animals,

00:26:22creates shade and protects it from heat.

00:26:24The lateral branches are

00:26:26the most important parts of the plant

00:26:28because they carry out photosynthesis

00:26:30and accumulate a large amount of humidity

00:26:32inside.

00:26:34Thus, despite all the dangers it presents,

00:26:36this cactus can be useful

00:26:38for people who move in the desert.

00:26:40And the danger here

00:26:42are the needles.

00:26:44If you look at them closely,

00:26:46you will notice their bearded appearance.

00:26:48You just have to touch them

00:26:50so that hundreds of thorns sink into your finger.

00:26:52It is difficult to get rid of them

00:26:54and the thorns cause extremely unpleasant

00:26:56painful sensations.

00:26:58But what is most interesting

00:27:00with this cactus

00:27:02is the way it reproduces.

00:27:04The plant clones itself in a new place.

00:27:06When animals and humans

00:27:08pass in front of this cactus and touch it,

00:27:10it gives them a small piece of itself

00:27:12with its thorns.

00:27:14As soon as this piece falls to the ground,

00:27:16it takes root and begins to grow.

00:27:18We increase the degree of danger.

00:27:20The next desert monster

00:27:22runs towards us.

00:27:24And it's an ostrich.

00:27:26Many people think that these animals

00:27:28are poultrons, just good

00:27:30to bury their heads in the sand.

00:27:32You would probably change your mind

00:27:34if you had the bad luck to meet one.

00:27:36In general, ostriches are not aggressive.

00:27:38But you will have to take your legs

00:27:40at your neck if you ever

00:27:42approach their nest.

00:27:44On the other hand, you have little chance

00:27:46to escape them because ostriches

00:27:48have a top speed of 70 km per hour.

00:27:50You will need a car to distance them

00:27:52because they sprint and hit

00:27:54their enemy in the chest.

00:27:56It even happened that ostriches

00:27:58attack trucks and cause

00:28:00significant damage to them.

00:28:02But the main danger

00:28:04represented by these volatiles

00:28:06is the head with clenched claws.

00:28:08With these, they can

00:28:10carry powerful blows and even

00:28:12hit an opponent on the ground.

00:28:14So yes, if you see an ostrich

00:28:16in the distance, pass your way.

00:28:18This little sharp lizard

00:28:20spends almost all his time underground.

00:28:22In the arid deserts of the southwest

00:28:24of the United States and northwest of Mexico.

00:28:26Sometimes,

00:28:28he goes out to look for his meal.

00:28:30He looks like a trognon like that.

00:28:32But to tell the truth,

00:28:34he is a dangerous gila monster.

00:28:36Its thick skin protects it from falcons,

00:28:38coyotes and other predators.

00:28:40But its main asset

00:28:42is its venom.

00:28:44Snakes and spiders inject

00:28:46their toxins with clenched claws.

00:28:48But the gila monster

00:28:50clings to its prey and the mesh

00:28:52to spread its venom.

00:28:54And when a person dies,

00:28:56he is able to keep his jaws closed

00:28:58for a very long time.

00:29:00It is difficult to get rid of the animal.

00:29:02People who have felt the effects

00:29:04of its venom say they had the impression

00:29:06that fused lava was passing through their veins.

00:29:08Despite this,

00:29:10the lizard proved useful to science.

00:29:12Doctors have exploited its venom

00:29:14to design drugs

00:29:16against diabetes and obesity.

00:29:18The time has come.

00:29:20Get ready to meet

00:29:22one of the scariest creatures in the desert.

00:29:24Make no noise

00:29:26and just enjoy the silence.

00:29:28Do not move, there is no one around.

00:29:30Suddenly, you hear a whistle

00:29:32coming from below.

00:29:34You lower your head and you see it.

00:29:36A big yellow spider

00:29:38the size of the palm of your hand,

00:29:40with powerful jaws and long legs

00:29:42lurks in the shadow of your body.

00:29:44Horrified, you flee this monster.

00:29:46But it pursues you.

00:29:48It is not easy to do in such a situation.

00:29:50But try to calm down.

00:29:52The creature is not interested in you.

00:29:54It only wants your shadow

00:29:56to shelter from the scorching sun.

00:29:58In any case,

00:30:00it is better not to touch it.

00:30:02The powerful jaws of the lizard

00:30:04can cause very unpleasant sensations.

00:30:06It is the least we can say.

00:30:08Moreover, this creature is not

00:30:10exactly a spider.

00:30:12Of course, it belongs to the arachnid class.

00:30:14But it is a distinct species.

00:30:16The Solpugidae.

00:30:18It likes to bite.

00:30:20It is not fearful,

00:30:22and even quite aggressive.

00:30:24The lizard feeds on insects, lizards,

00:30:26and small birds.

00:30:28It can also move at a speed of 16 km per hour.

00:30:30Given its small size,

00:30:32it is very fast.

00:30:34You have to be a professional athlete

00:30:36to escape it.

00:30:38Most often,

00:30:40we find these Solpugidae

00:30:42in the deserts of the Middle East.

00:30:44But they also live in Mexico

00:30:46and in the southwest of the United States.

00:30:48These spiders are nocturnal

00:30:50and try to avoid the sun during the day

00:30:52so that they will always be in search of your shadow.

00:30:54They owe their name to the fact

00:30:56that they flee the sun in all circumstances.

00:30:58You will have no chance to escape them

00:31:00during the day.

00:31:02But they will also want to take you

00:31:04during the night.

00:31:06Especially if you make a fire.

00:31:08The Solpugidae always run towards the light

00:31:10in the hope of catching something.

00:31:12Some species of spider lizards

00:31:14even emit a whistle to frighten their enemies.

00:31:16Let's calm down for a moment

00:31:18and leave this burning desert.

00:31:20We enter the humid tropics of Tanzania.

00:31:22Under the bark of the trees,

00:31:24the mats of dead leaves

00:31:26and in the dark caves,

00:31:28you could meet one of the most terrifying creatures

00:31:30on the planet.

00:31:32The Amblypige

00:31:34or 24-hour spider.

00:31:36Imagine a big scorpion without a tail

00:31:38with a flat body that seems to have been compressed.

00:31:40It looks like spiders

00:31:42but has no venom glands

00:31:44and cannot weave webs.

00:31:46This monster is fast and silent.

00:31:48But what is most frightening

00:31:50are its two front claws

00:31:52twice as long as the creature itself.

00:31:54Any prey it catches

00:31:56will never escape.

00:31:58Its entire life spent in a dark cave

00:32:00has altered its sight and the Amblypige

00:32:02tries to avoid the sunlight.

00:32:04During the night, it climbs to the ceiling

00:32:06and slowly gets rid of its old skin.

00:32:08Imagine directing your lamp to this place

00:32:10to see small cocoons

00:32:12from where pale spiders

00:32:14with excessively long legs come out.

00:32:16If you meet this creature in real life,

00:32:18keep calm

00:32:20and move away as far as possible.

00:32:22Stay on your guards.

00:32:24The Amblypige can slip under your clothes

00:32:26in a wink and bite you in the abdomen.

00:32:28And it's nothing compared to what's waiting for you.

00:32:30Okay, it's a joke.

00:32:32This nice little guy

00:32:34is one of the most shy

00:32:36and most harmless creatures among all the arachnids.

00:32:38He is afraid of us

00:32:40and will never take you.

00:32:42Many find him majestic

00:32:44and keep Amblypige in glass-made terrariums.

00:32:46If you want such a pet,

00:32:48watch out

00:32:50so that it does not run away from its home.

00:32:52Because if this happens,

00:32:54it will be very difficult to catch up with it.

00:32:56In a few moments,

00:32:58it can slip under your bed

00:33:00or pass through the interstices of the floor.

00:33:02Then it will go into your neighbor's apartment

00:33:04through the ventilation system

00:33:06and terrorize the people who are there.

00:33:10Well,

00:33:12and why not a little scorpion for the road?

00:33:14The latter is not as scary

00:33:16as the other creatures in this video.

00:33:18But this is the most venomous scorpion

00:33:20in the United States.

00:33:22The Centruroide Sculturatus of Arizona.

00:33:24The problem is

00:33:26that it can be found in the desert,

00:33:28at home or in your garden.

00:33:30This dangerous venomous creature

00:33:32slides into rooms and often stings people.

00:33:34A single sting

00:33:36is enough to cause a pain

00:33:38similar to that of a bee sting.

00:33:40But an allergic person can suffer

00:33:42from paralysis, respiratory distress

00:33:44and other extremely serious

00:33:46health problems.

00:33:48The Baltic Sea Anomaly

00:33:50In 2011,

00:33:52a diving team went all the way

00:33:54down to the bottom of the Baltic Sea,

00:33:56to the north.

00:33:58They went hunting for treasures.

00:34:00But they discovered a rather bizarre object.

00:34:02They took pictures that they then shared

00:34:04and some people thought

00:34:06it was the spaceship

00:34:08of an unknown civilization.

00:34:10They thought that a natural phenomenon

00:34:12had given shape to this object.

00:34:14But the metals inside the structure

00:34:16could not have been formed naturally.

00:34:18Today, some scientists

00:34:20think it is an object

00:34:22from the Ice Age.

00:34:24Maybe even from a meteorite

00:34:26that was caught in the ice at that time.

00:34:28A maelstrom

00:34:30is a whirlwind,

00:34:32a kind of powerful rotating current

00:34:34that forms when two currents meet,

00:34:36creating a circular vortex.

00:34:38Even the intrepid Vikings

00:34:40were afraid of maelstroms.

00:34:42Their power was such

00:34:44that they could make very large ships sink.

00:34:46These whirlwinds are still dangerous

00:34:48today.

00:34:50But fortunately,

00:34:52the great modern ships

00:34:54are no longer afraid of anything.

00:34:56They are now able

00:34:58to resist this power.

00:35:00However, a shipwreck

00:35:02that crosses the path of a maelstrom

00:35:04will generally be exposed

00:35:06because some maelstroms

00:35:08are so formidable

00:35:10that they are sometimes compared

00:35:12to black holes.

00:35:14And no, black holes

00:35:16do not only belong to the interstellar space.

00:35:18They are found here,

00:35:20on our planet,

00:35:22in the form of oceanic whirlwinds.

00:35:24What brings them closer

00:35:26to these celestial monsters

00:35:28is the fact that nothing

00:35:30they capture can escape them.

00:35:32These underwater black holes

00:35:34probably don't even notice.

00:35:36Their influence extends far beyond

00:35:38what can be detected.

00:35:40Because of their size,

00:35:42they even escape the most modern equipment.

00:35:44Here is something more relaxing.

00:35:46The next time you go to the beach,

00:35:48open your eyes wide

00:35:50and you may see this optical phenomenon

00:35:52called the green flash.

00:35:54You can see it a little after sunset

00:35:56or just before sunrise.

00:35:58It occurs when the sun

00:36:00is almost completely below the horizon

00:36:02and the upper part of the sky is still visible.

00:36:04For one or two seconds,

00:36:06the solar crown will seem green to you.

00:36:08Because in reality,

00:36:10you will observe the sun

00:36:12through the thickest parts

00:36:14of the atmosphere,

00:36:16at the bottom of the sky.

00:36:18As it descends below the horizon,

00:36:20its light refracts into the atmosphere

00:36:22or curves and disperses.

00:36:24Choose a clear day,

00:36:26without clouds or mist on the horizon

00:36:28and you will be able to see this phenomenon.

00:36:30You were impatient to swim,

00:36:32but when you arrive at the beach,

00:36:34you see that the ocean is red.

00:36:36It is better to avoid making trumpets.

00:36:38Florida is famous for its red tides.

00:36:40This occurs when the concentration

00:36:42of the Karenia brevis algae

00:36:44is higher than normal.

00:36:46Most of the algae in the sea,

00:36:48rivers and lakes

00:36:50are safe for animals and humans.

00:36:52They even help us.

00:36:54They are indeed a great source of oxygen.

00:36:56But some,

00:36:58such as those that give this red tint to the ocean,

00:37:00can be extremely dangerous

00:37:02for the aquatic fauna,

00:37:04sea turtles, fish and marine birds.

00:37:06This type of algae

00:37:08can develop uncontrollably

00:37:10and produce very harmful neurotoxins

00:37:12for humans,

00:37:14especially for those who have respiratory problems.

00:37:16These people must at all costs

00:37:18avoid areas of red tides,

00:37:20especially when strong winds

00:37:22push the algae to the shore.

00:37:24Volcanoes can emit toxic gases,

00:37:26such as ash and red lava.

00:37:28These dangers have been well known

00:37:30to humans for centuries.

00:37:32But underwater volcanoes

00:37:34can also be dangerous.

00:37:36Sometimes, those located

00:37:38in shallow waters

00:37:40reveal their presence

00:37:42by projecting rock debris and steam

00:37:44very high above the surface.

00:37:46Because of the presence of water,

00:37:48their effects will be different

00:37:50from those found on dry land.

00:37:52When they erupt,

00:37:54the lava can spread

00:37:56on the ocean floor.

00:37:58Sometimes,

00:38:00it can spill from land volcanoes.

00:38:02When it enters the water,

00:38:04it cools down so quickly

00:38:06that it can turn into gravel.

00:38:08Volcanic debris

00:38:10is found in large quantities in these areas.

00:38:12Have you ever seen

00:38:14these strange black sand beaches in Hawaii?

00:38:16They are the result of this activity.

00:38:18Lava and powerful eruptions

00:38:20represent an obvious danger.

00:38:22But underwater volcanoes,

00:38:24in deep waters,

00:38:26are just as dangerous,

00:38:28even when they do not erupt.

00:38:30They produce air pockets.

00:38:32These bubbles reduce the density

00:38:34of the surrounding waters,

00:38:36which can even cause shipwrecks.

00:38:38The worst is that when you look

00:38:40at the surface of the ocean,

00:38:42you will not know that a danger is waiting for you.

00:38:44You will not see these air pockets

00:38:46that can unbalance even very large ships.

00:38:48And without warning.

00:38:50Crossing the sea is a rare phenomenon.

00:38:52Beautiful to observe,

00:38:54but also very dangerous.

00:38:56It is when you see square waves.

00:38:58They are quite common

00:39:00in the shallow areas of the ocean.

00:39:02You can observe this phenomenon

00:39:04near the island of Ré

00:39:06or from the beaches of Tel Aviv,

00:39:08but also in many other areas

00:39:10of the world.

00:39:12This occurs when two waves

00:39:14propagating in two different directions

00:39:16come together.

00:39:18This usually happens

00:39:20after the passage of an atmospheric front.

00:39:22And this state of the sea

00:39:24is structured in a large number

00:39:26of directional flows.

00:39:28These waves can be dangerous

00:39:30for swimmers and amateurs.

00:39:32The waves produced by

00:39:34strong ocean currents

00:39:36can be unpredictable

00:39:38and measured up to 3 meters high.

00:39:40They are sometimes called

00:39:42white walls.

00:39:44Their power is such

00:39:47that if you fill a glass

00:39:49with seawater and look carefully,

00:39:51you will see quantities

00:39:53of very small particles.

00:39:55The seawater contains

00:39:57dissolved salts, fats,

00:39:59algae, proteins and other

00:40:01artificial and organic debris.

00:40:03If you shake the glass,

00:40:05tiny bubbles will appear

00:40:07on its surface.

00:40:09This is how seawater is formed

00:40:11when waves and winds

00:40:13shake the ocean.

00:40:15Seawater is caused by

00:40:17a large concentration of algae.

00:40:19When algae disintegrate

00:40:21in the sea, their matter

00:40:23often drifts to the shores.

00:40:25In general, seawater

00:40:27is not dangerous for humans.

00:40:29But when it contains

00:40:31decomposed algae,

00:40:33it can be harmful

00:40:35to our environment.

00:40:37It can happen that

00:40:39air pockets burst

00:40:41and release toxins

00:40:43Masses of seawater

00:40:45occur in the mouth

00:40:47and the lower reaches

00:40:49of certain streams.

00:40:51A strong tidal wave

00:40:53meets the current

00:40:55and pushes the river back.

00:40:57Masses of seawater

00:40:59are part of the hydraulic

00:41:01spring category,

00:41:03a sudden change

00:41:05in the water level.

00:41:07It is a positive push,

00:41:09which means that the wave

00:41:11will not come back.

00:41:13You will not see masks everywhere.

00:41:15The river must be shallow

00:41:17and its mouth must be narrow.

00:41:19The area where the sea

00:41:21and the river meet

00:41:23must be flat and wide.

00:41:25In addition, the area

00:41:27between the low tide

00:41:29and the high tide

00:41:31must be at least 6 m wide.

00:41:33Of course, there are some exceptions,

00:41:35like the Amazon,

00:41:37the largest river in the world.

00:41:39Its mouth is shallow

00:41:41and has many sands

00:41:43and other low islands.

00:41:45This mass of seawater

00:41:47is the reason why the Amazon

00:41:49does not have a real delta.

00:41:51The Atlantic Ocean

00:41:53quickly takes away

00:41:55these sediments,

00:41:57preventing such a formation.

00:41:59Masses of seawater

00:42:01are often unpredictable

00:42:03and can be extremely violent.

00:42:05It even happens that

00:42:07you can tear down trees.

00:42:09So leisure sports

00:42:11like kayaking and surfing

00:42:13can be dangerous in these areas.

00:42:15But if you just want to observe

00:42:17a masquerade a little closer,

00:42:19be careful.

00:42:21It could literally

00:42:23tear the ground under your feet

00:42:25and carry you in these agitated waters.

00:42:27Have you ever seen

00:42:29a sea cucumber lying on a sand bed

00:42:31and thought it looked like a blob?

00:42:33These creatures may seem

00:42:35harmless, but they actually

00:42:37have fascinating strategies

00:42:39to protect themselves.

00:42:41Biologists have discovered

00:42:43chemical compounds

00:42:45that allow sea cucumbers

00:42:47to protect themselves

00:42:49from predators

00:42:51and even from their own toxins.

00:42:53And guess what?

00:42:55These compounds

00:42:57could be useful

00:42:59to human health.

00:43:01When sea cucumbers feel threatened,

00:43:03their toxicity comes from

00:43:05certain chemical compounds

00:43:07commonly found in plants.

00:43:09It's interesting to note

00:43:11that these chemicals

00:43:13are much less common

00:43:15in animals,

00:43:17but sea cucumbers have evolved

00:43:19to use them to their advantage.

00:43:21These substances are also

00:43:23known for their antioxidant

00:43:25and anti-inflammatory properties.

00:43:27They are already used

00:43:29in a large number of industries

00:43:31and their defense mechanisms

00:43:33pose a major problem

00:43:35for sea cucumbers.

00:43:37They must avoid

00:43:39contaminating themselves

00:43:41with their own toxins.

00:43:43This means that their own cells

00:43:45must not contain cholesterol,

00:43:47the target to which toxins

00:43:49bind and cross.

00:43:51Sea cucumbers have therefore

00:43:53developed two types

00:43:55of cholesterol alternatives.

00:43:57This is a self-defense strategy.

00:43:59They are also known

00:44:01to make you sick.

00:44:03As smart and cute as they are,

00:44:05you now know

00:44:07that you should not touch

00:44:09a sea cucumber

00:44:11if you happen to meet one

00:44:13on the beach.

00:44:15Speaking of things to avoid

00:44:17on the beach,

00:44:19let's move on to the marbled conch.

00:44:21A creature so unique

00:44:23and so dangerous

00:44:25that it will make you turn your head.

00:44:27The marbled conch is found

00:44:29in the south-east of New Caledonia

00:44:31and the Samoa.

00:44:33It is an impressive area

00:44:35and it is not only the place

00:44:37where it is found that is interesting,

00:44:39it is also the way

00:44:41it hunts.

00:44:43This snail may be small,

00:44:45but it is a ferocious predator.

00:44:47It loves to devour other snails

00:44:49and sometimes even its own congeners.

00:44:51When it is hungry,

00:44:53it takes out its long white teeth

00:44:55and if that is not enough,

00:44:57it will attack its prey several times

00:44:59just to be sure.

00:45:01What determination, isn't it?

00:45:03Once the marbled conch has reached its target,

00:45:05the prey is immobilized

00:45:07and its muscles begin to relax

00:45:09in an irreversible way.

00:45:11When the prey is defenseless,

00:45:13the snail can start to devour it.

00:45:15Where can we find

00:45:17this formidable creature,

00:45:19you ask?

00:45:21It is found in shallow waters,

00:45:23coral reefs or lagoon pinnacles,

00:45:25as well as in the sand,

00:45:27under rocks

00:45:29or among marine grass.

00:45:31Be careful where you put your feet

00:45:33the next time you go swimming,

00:45:35that is to say.

00:45:37The good side of things

00:45:39is that the venom of this snail

00:45:41is being developed

00:45:43as a potential treatment for pain.

00:45:45Some of the chemical substances

00:45:47it contains have been studied

00:45:49and prove promising.

00:45:51The next one on our list

00:45:53of creatures to avoid

00:45:55is a small fish called

00:45:57stone fish.

00:45:59You may think it is a pretty little stone

00:46:01but let me tell you

00:46:03that you must not be wrong.

00:46:05In fact, it is the most venomous fish

00:46:07in the entire ocean.

00:46:09These fish are masters of disguise,

00:46:11basing themselves in their environment

00:46:13on the rocky or vast bottom

00:46:15of the marine habitats

00:46:17of the Indo-Pacific region.

00:46:19They are sea ninjas

00:46:21who patiently wait for their prey

00:46:23to get close before attacking

00:46:25and swallowing it whole.

00:46:27But the problem is that

00:46:29you can easily pass by a stone fish

00:46:31without even realizing

00:46:33its presence.

00:46:35I know what you're thinking,

00:46:37I don't want to walk accidentally

00:46:39on a stone fish,

00:46:41and believe me,

00:46:43you really don't want to.

00:46:45These fish have a lot of spines on their backs

00:46:47Ouch! This venom can cause

00:46:49terrible pain, swelling

00:46:51and tissue lesions.

00:46:53It's not really a good day

00:46:55at the beach if you ask me.

00:46:57But don't worry,

00:46:59the stone fish is not here to catch you.

00:47:01It uses its spines for defensive

00:47:03and non-offensive purposes.

00:47:05As long as you don't disturb it

00:47:07and you don't walk on it,

00:47:09everything should be fine.

00:47:11Just pay attention to where you put your feet

00:47:13and maybe invest in water shoes.

00:47:15And if you get stung,

00:47:17immediately consult a specialist.

00:47:19It is preferable to always watch

00:47:21where you walk,

00:47:23to drag your feet on the bottom

00:47:25to avoid walking directly on the fish

00:47:27and to wear water shoes

00:47:29if you are in an area

00:47:31susceptible to stone fish.

00:47:33Have you ever had the pleasure

00:47:35to meet a lion fish up close?

00:47:37These are beautiful creatures

00:47:39with all their colors

00:47:41and their fins that look like wings

00:47:43It is easy to be fascinated

00:47:45by their elegance,

00:47:47but don't be fooled

00:47:49by their stunning appearance.

00:47:51You shouldn't make fun of them.

00:47:53In fact, it is one of the most dangerous fish

00:47:55in the ocean.

00:47:57In case of sting,

00:47:59you will feel a sharp pain

00:48:01or even allergic reactions.

00:48:03The lion fish injects its venom

00:48:05through its dorsal fins

00:48:07and sharp fins.

00:48:09They are not aggressive

00:48:11and can be provoked or caught.

00:48:13It is not only their venom

00:48:15that makes them dangerous,

00:48:17they also have tiny teeth.

00:48:19But instead of using them

00:48:21to bite predators,

00:48:23they have something even more dangerous,

00:48:25their fins.

00:48:27The lion fish uses its fins

00:48:29in the form of a spine

00:48:31to repel predators

00:48:33and unfortunately humans are part of it.

00:48:35So even if it is tempting

00:48:37to approach this fish

00:48:39with its sharp fins.

00:48:41But here it is,

00:48:43the lion fish can be eaten.

00:48:45Some say they are even delicious.

00:48:47And as they pose a threat

00:48:49to the reefs' ecosystems,

00:48:51their consumption is encouraged.

00:48:53You just have to make sure

00:48:55to remove the venomous fins first.

00:48:57If you dive with a mask and a tuba,

00:48:59or if you swim near corals

00:49:01in the Atlantic or Pacific Ocean,

00:49:03you may meet these amazing fish.

00:49:05Keep a reasonable distance

00:49:07from the lion fish

00:49:09and it will not feel threatened

00:49:11or frightened to the point of biting you

00:49:13to defend itself.

00:49:15Bears can also cause problems

00:49:17if you fall on them.

00:49:19Do not worry,

00:49:21they will not jump from the reef

00:49:23and will not throw thorns at you.

00:49:25They are not at all aggressive.

00:49:27These creatures are everywhere,

00:49:29from rocky banks to coral reefs

00:49:31and are very common

00:49:33in almost all saltwater areas,

00:49:35so it is not surprising

00:49:37that the wounds caused by bears

00:49:39are also quite common.

00:49:41But accidents happen

00:49:43especially when we are distracted

00:49:45by a pretty little turtle

00:49:47or too excited to explore

00:49:49a new diving site.

00:49:51Let's talk now

00:49:53about their defense mechanism.

00:49:55These little animals

00:49:57have two ways to defend themselves.

00:49:59Their spines and these tiny structures

00:50:01in the shape of jaws

00:50:03can easily pierce

00:50:05a thick dive suit

00:50:07and land deeply in your skin.

00:50:09Ouch!

00:50:11But do not worry,

00:50:13avoiding bears is not a wizard.

00:50:15Just try to be aware

00:50:17of what surrounds you,

00:50:19to pay attention to the spines

00:50:21that protrude in the sand

00:50:23and to control your floatability.

00:50:25This will help you stay a few meters

00:50:27away from the corals

00:50:29that can hide bears in their crevasses.

00:50:31But if you have chosen

00:50:33another diving site,

00:50:35it does not matter.

00:50:37Let's now talk about the first

00:50:39care to be taken

00:50:41in the event of a bear bite.

00:50:43Soaking the area in hot water

00:50:45for an hour and a half

00:50:47can help you decompose

00:50:49the dangerous substance

00:50:51and relieve the pain.

00:50:53Carefully remove the spines

00:50:55with a tweezers

00:50:57and shave the area

00:50:59that you have in your beach bag.

00:51:01And of course,

00:51:03monitor the signs of allergies

00:51:05and contact a specialist

00:51:07if you notice something strange.

00:51:09But do not forget that bears

00:51:11are only one of the many dangers

00:51:13of the depths.

00:51:15There are also bearded fireworms,

00:51:17globefish and fire coral.

00:51:19So let's not be too hard

00:51:21with our little bear friends.

00:51:23After all, compared to some

00:51:25of these other creatures,

00:51:27the PINCE code can offer

00:51:29a crucial protection

00:51:31against potential burglaries.

00:51:33This PINCE code

00:51:35consists of a series

00:51:37of notes and cryptic alerts

00:51:39that burglars use

00:51:41to communicate with each other.

00:51:43They thus warn their accomplices

00:51:45of the risks and dangers

00:51:47they could face

00:51:49by attacking a specific property.

00:51:51By understanding and decrypting

00:51:53the PINCE code,

00:51:55we can protect our houses

00:51:57and the property of intruders

00:51:59and ensure our peace of mind

00:52:01by reinforcing security.

00:52:03Look at this,

00:52:05a pretty garden dwarf.

00:52:07Well, if it does not belong to you

00:52:09and you have not placed it

00:52:11yourself, it is an agent

00:52:13of the PINCE code.

00:52:15The police are on guard

00:52:17against a worrying trend

00:52:19involving the placement

00:52:21of unknown dwarfs

00:52:23in the PINCE code.

00:52:25You must therefore always

00:52:27remain vigilant and take

00:52:29the necessary measures

00:52:31to protect your property.

00:52:33American authorities report

00:52:35that a gang of burglars

00:52:37lurking in the county

00:52:39of Fairfax, Virginia,

00:52:41entered the houses

00:52:43using bouquets of flowers

00:52:45and aerosol paint bombs.

00:52:47It would seem that a woman

00:52:49was at the door with the flowers

00:52:51and dropped the jewels and money.

00:52:53They try to remain unnoticed

00:52:55by interfering with the security cameras

00:52:57of the houses.

00:52:59The burglars draw mysterious symbols

00:53:01in the street to communicate

00:53:03with other criminals about potential targets.

00:53:05These symbols can indicate

00:53:07that a house is safe,

00:53:09that it has already been burglarized

00:53:11or that it does not really contain

00:53:13any valuables.

00:53:15More alarmingly,

00:53:17they can also indicate

00:53:19that it is particularly credulous

00:53:21or easy to frighten.

00:53:23The police have managed to decipher

00:53:25the meaning of several of these symbols.

00:53:27For example, an X suggests

00:53:29that the house would be a good target,

00:53:31while an X surrounded by a circle

00:53:33indicates that there is nothing

00:53:35to steal inside.

00:53:37A barred capital D means

00:53:39that entering the house is too risky,

00:53:41while five star-shaped circles

00:53:43indicate a wealthy house.

00:53:45Additional symbols can reveal

00:53:47that a house is safe,

00:53:49that it has already been burglarized

00:53:51or that it does not really contain

00:53:53any valuables.

00:53:55These symbols are not the only things

00:53:57to watch out for.

00:53:59Beware of unknown walkers

00:54:01who may seem hesitant or suspicious

00:54:03when they knock on your door.

00:54:05If they are not able to present

00:54:07an official piece of identity

00:54:09or a valid reason for their presence,

00:54:11it is preferable to remain vigilant.

00:54:13Be careful with anyone

00:54:15who tries to enter your house.

00:54:19It is important to stay aware

00:54:21of what is happening around you,

00:54:23especially with regard to

00:54:25shady people who could be

00:54:27lurking around your house.

00:54:29Keep an eye on anyone

00:54:31who seems to be lurking

00:54:33near your house,

00:54:35sniffing out suspicious notes

00:54:37or simply observing your property

00:54:39with a little too much interest.

00:54:41This behavior could indicate

00:54:43a vulnerability in the security

00:54:45of your home.

00:54:47Be sure to report any suspicious

00:54:49behavior to the authorities

00:54:51and take the necessary precautions

00:54:53to protect you and your property

00:54:55from possible threats.

00:54:57In addition, beware of these individuals

00:54:59who claim to conduct surveys

00:55:01or market studies.

00:55:03If some surveys are more or less legitimate,

00:55:05scammers could very well use them

00:55:07as a way to collect information

00:55:09about your home and your daily habits.

00:55:11If you have a charitable association

00:55:13that seems to be more interested

00:55:15in your home than in your donations

00:55:17or your obedience,

00:55:19it could be a sign of a potential scam.

00:55:21Also be vigilant with any unknown vehicle

00:55:23driving around your neighborhood

00:55:25as it could be tracking potential targets.

00:55:27If you find your box

00:55:29with letters full of leaflets

00:55:31or brochures,

00:55:33it could be a sign that someone

00:55:35is keeping an eye on your house

00:55:37or trying to collect information.

00:55:39Do not try to cause a false accident

00:55:41to incite you to leave your home.

00:55:43Be careful and do not fall into the trap.

00:55:45In case of doubt,

00:55:47do not hesitate to call 112.

00:55:49In addition, beware of these strange

00:55:51phone calls where your correspondent

00:55:53does not say a word.

00:55:55If you receive repeated calls of this type,

00:55:57it could be a sign that your home

00:55:59is targeted by burglars

00:56:01who want to know if you are well there.

00:56:03Finding a pizzeria brochure

00:56:05or a newspaper under your straw

00:56:07could be a sign that your home

00:56:09is being watched.

00:56:11If these things were left overnight,

00:56:13it could leave potential intruders

00:56:15to know that the house is empty.

00:56:17Make sure to make them disappear

00:56:19as soon as you return.

00:56:21Adrian Pritchard,

00:56:23once one of the most wanted criminals

00:56:25in New Zealand,

00:56:27now devotes himself to helping people

00:56:29to prevent the burglaries

00:56:31he used to commit.

00:56:33Pritchard spent a decade committing

00:56:35hundreds of burglaries

00:56:37that began when he was still a child.

00:56:39More than 20 years after his last

00:56:41release from prison, Pritchard,

00:56:43who is now in his fifties,

00:56:45would like to share his knowledge

00:56:47on crime prevention.

00:56:49Pritchard and his associates

00:56:51did their surveillance during the day

00:56:53and entered the properties at night.

00:56:55They used various techniques

00:56:57to explore houses and shops

00:56:59without being detected.

00:57:01In addition, they sometimes delivered

00:57:03acts of pure vandalism,

00:57:05such as completely returning

00:57:07the victim's house by force.

00:57:09Today, Pritchard lives in Hawkes Bay

00:57:11with his three daughters

00:57:13and devotes himself to helping

00:57:15his neighbors to prevent burglaries.

00:57:17By relying on his past experiences,

00:57:19he offers valuable advice

00:57:21on domestic security,

00:57:23such as investing in surveillance cameras,

00:57:25keeping valuables away from windows

00:57:27and avoiding hiding places

00:57:29that are too common

00:57:31and having a good lock

00:57:33and emptying his mailbox regularly.

00:57:35Barbed wire can provide

00:57:37an additional security measure.

00:57:39Through his efforts to educate

00:57:41the owners, he strives

00:57:43to prevent them from suffering

00:57:45the same insults he once inflicted

00:57:47on others.

00:57:49Returning home, in a fresh

00:57:51and tidy house after the holidays

00:57:53is always a deep relief.

00:57:55But it is important to remember

00:57:57that a perfectly impeccable house

00:57:59is a place where no one is.

00:58:01Try to leave some everyday objects

00:58:03in sight, such as a board

00:58:05to iron with a pile of clothes

00:58:07that must be ironed.

00:58:09This will give the impression

00:58:11that you have just left

00:58:13instead of being absent

00:58:15for a long time.

00:58:17In addition, you should never

00:58:19publish information

00:58:21about your holidays

00:58:23on social networks.

00:58:25And it is recommended

00:58:27that someone is always at home

00:58:29during your absence.

00:58:31You can ask a friend

00:58:33to park his car in your alley

00:58:35or to leave the radio on at full volume.

00:58:37It would also be wise

00:58:39to ask someone to close

00:58:41and open your curtains

00:58:43or doors to give the impression

00:58:45that the house is busy.

00:58:47Also make sure to delete

00:58:49any obvious traces of your absence,

00:58:51such as a labeled envelope,

00:58:53holiday money,

00:58:55or your friends or neighbors

00:58:57who may be unable to do it themselves

00:58:59due to a hospitalization

00:59:01or a professional trip.

00:59:03Simple tasks such as mopping the floor,

00:59:05picking up the mail,

00:59:07and even taking out your own trash

00:59:09can help to dissuade potential burglars

00:59:11by giving the impression

00:59:13that someone is always present.

00:59:15Refreshing the appearance of the house

00:59:17by replacing its discolored curtains

00:59:19or by mowing the garden

00:59:21can also help to prevent frictions.

00:59:23If you notice these signs

00:59:25or if you are suspicious

00:59:27of any door-to-door activity,

00:59:29it is important to know how to contact

00:59:31the authorities so that they can help you.

00:59:33Always prioritize your safety

00:59:35and that of your home

00:59:37while remaining vigilant

00:59:39and taking appropriate precautions.

00:59:41Remember, although these signs

00:59:43do not always indicate a criminal activity,

00:59:45they should still encourage you

00:59:47to take the necessary measures.

00:59:49Are you used to taking hitchhikers

00:59:51on the road?

00:59:53In this case, you should be aware

00:59:55of the hitchhiker's scam on the road.

00:59:57It is a scam that aims

00:59:59at unsuspecting drivers.

01:00:01The scam usually starts with a person

01:00:03who pretends to be a hitchhiker

01:00:05and signs a car on the side of the road.

01:00:07She may claim to be in distress

01:00:09or need a driver

01:00:11to get to a neighboring city.

01:00:13In some cases, the hitchhiker

01:00:15can ask the driver

01:00:17to stop at a specific place

01:00:19where he will disappear with the money

01:00:21or other valuables that he has stolen.

01:00:23This scam can also take place as a team.

01:00:25A group of people signs a car

01:00:27and asks to be stopped.

01:00:29Once the car is on the road,

01:00:31they threaten the driver

01:00:33and steal money, valuables,

01:00:35even the car itself.

01:00:37It is important to be aware

01:00:39of this scam and to always be careful

01:00:41when taking people on the road.

01:00:43It is preferable to avoid giving

01:00:45money or other valuables

01:00:47to anyone who claims

01:00:49to need a transport

01:00:51and to never stop at a place

01:00:53that is not safe or familiar.

01:00:55Hitchhikers are not the only

01:00:57cause of trouble on the road.

01:00:59A slice of cheese is not something

01:01:01you expect to find on your parked car,

01:01:03is it?

01:01:05Yet it may be the sign of a dangerous situation.

01:01:07A woman told this online experience

01:01:09thinking it was a simple farce

01:01:11made by a young man in the neighborhood.

01:01:13She decided to call a friend

01:01:15to help her clean the car.

01:01:17But when the two women began

01:01:19to remove the melted cheese on the windshield,

01:01:21they saw something strange nearby.

01:01:23She remembers seeing

01:01:25a white truck.

01:01:27Inside were several men

01:01:29who looked at them suspiciously.

01:01:31As she was not alone,

01:01:33she judged that there was no danger

01:01:35to end up cleaning the car.

01:01:37Even if she did not feel comfortable

01:01:39with the idea of being stripped.

01:01:41It took them nearly an hour

01:01:43to remove the cheese that had melted

01:01:45under the heat.

01:01:47She still wondered if it was not

01:01:49a tactic to steal a person.

01:01:51Indeed, most people would be

01:01:53so focused on cleaning their car

01:01:55that they would be distracted

01:01:57and would not keep an eye

01:01:59on the objects they left in the car,

01:02:01such as bags, wallets,

01:02:03or even recently purchased articles.

01:02:05Sometimes it could be

01:02:07a removal strategy.

01:02:09The sticky cheese would force the person

01:02:11to clean the car and prevent

01:02:13him from seeing the suspicious people

01:02:15who would approach her in time.

01:02:17What must be remembered

01:02:19from this story,

01:02:21if you ever see a piece of cheese

01:02:23on your car, leave it as it is,

01:02:25as long as it does not block your view

01:02:27and does not really affect your driving.

01:02:29The safest thing is to

01:02:31clean it at home.

01:02:33Or you have to go to the nearest

01:02:35washing station,

01:02:37who will know how to clean the vehicle

01:02:39without damaging the paint.

01:02:41Of course, the scam of a piece of cheese

01:02:43on a car may be

01:02:45just a coincidence.

01:02:47But some scams are more legitimate,

01:02:49such as the following, which is a

01:02:51rather unusual method to seize

01:02:53other people's cars.

01:02:55If you notice a t-shirt or a hoodie

01:02:57on your windshield, or even wrapped

01:02:59between your broomsticks,

01:03:01do not rush to get rid of it.

01:03:03Again, it may be

01:03:05a deliberately placed object

01:03:07that distracts your attention

01:03:09while your car is being taken away.

01:03:11Leave as quickly as possible,

01:03:13if you can, and go to a safe place,

01:03:15well lit and crowded with people.

01:03:17There, you will be able to

01:03:19risklessly remove the object

01:03:21that is on your car.

01:03:23Some people even found money

01:03:25under their windshield wipers.

01:03:27It is quite obvious that those

01:03:29who left it there probably had

01:03:31the same intention.

01:03:33There are effective methods

01:03:35When you park your car,

01:03:37make sure your tires are turned

01:03:39towards the sidewalk.

01:03:41If the wheels of the car are in this position,

01:03:43the thieves are less likely to be able

01:03:45to move with the vehicle.

01:03:47They will see that the car needs more time

01:03:49and energy to move,

01:03:51and it will therefore become a less interesting target.

01:03:53Unfortunately,

01:03:55scams on the road are quite common,

01:03:57and one of the most common

01:03:59is the famous scam at the car wash.

01:04:01This scam consists of leaving

01:04:03oil stains, metallic nails

01:04:05or glass splinters on the road

01:04:07and waiting for the drivers to fall into the trap.

01:04:09If such a practice damages the car,

01:04:11scams arise from nowhere

01:04:13and offer you

01:04:15very high-priced towing services.

01:04:17They will try to put pressure on you

01:04:19so that you use their services,

01:04:21because most of the time they place

01:04:23these traps in strategic places.

01:04:25They make sure that people are isolated

01:04:27in places where visibility is reduced

01:04:29and where there is no service station

01:04:31to assess the damage

01:04:33caused to the car.

01:04:35If, for example, towing

01:04:37is the only possible option,

01:04:39the towman will take advantage of it

01:04:41to take the car to unpleasant workshops

01:04:43by your insurance company.

01:04:45This means that you will have to pay

01:04:47even more money to get your car back.

01:04:49If you have been driving for a long time,

01:04:51you know that the driver

01:04:53who hits another vehicle from behind

01:04:55is always responsible.

01:04:57Indeed, it is always advisable

01:04:59to drive more comfortably

01:05:01compared to the previous car

01:05:03in order to be able to stop

01:05:05safely in an emergency situation.

01:05:07Some scams take advantage of this

01:05:09to brake abruptly several times,

01:05:11causing a collision.

01:05:13This dangerous tactic is used

01:05:15to get money for alleged damage

01:05:17and even for false medical fees.

01:05:19To avoid being a victim of this scam,

01:05:21it is advisable to slow down

01:05:23and keep a safe distance,

01:05:25especially with suspicious vehicles

01:05:27If a scam continues to bother you

01:05:29in traffic,

01:05:31the best thing to do

01:05:33is to go to the nearest police station

01:05:35and report it.

01:05:37Let's take an example.

01:05:39You are driving on the road

01:05:41and suddenly a biker

01:05:43draws your attention

01:05:45and makes you notice

01:05:47that your wheels are smoking.

01:05:49You quickly stop on the low side of the road.

01:05:51The biker then offers to help you

01:05:53by calling a mechanic

01:05:55The mechanic arrives very quickly

01:05:57but he deactivates your braking system

01:05:59while he inspects the cause of the smoke.

01:06:01He then asks you to test your brakes,

01:06:03which will obviously not work

01:06:05since he has already deactivated them.

01:06:07Pretending to be helpful,

01:06:09he offers you to repair your brakes,

01:06:11but he will ask you a huge price for it.

01:06:13Moral of the story?

01:06:15Stay faithful to your mechanic

01:06:17or to your trustworthy company.

01:06:19You never know

01:06:21who you may meet on the road.

01:06:23Some burglaries

01:06:25are not even authentic

01:06:27but are urban legends.

01:06:29Many people claim to have seen

01:06:31the wrong way man

01:06:33on the roads.

01:06:35A version of this story

01:06:37mentions a man stuck in a street

01:06:39in a unique way,

01:06:41causing chaos and confusion

01:06:43while other drivers try to avoid it.

01:06:45It is said of this man that he is crazy

01:06:47and dangerous,

01:06:49with a wild look in the eyes

01:06:51Other versions say

01:06:53that he does not even drive

01:06:55but that once you see this mysterious person

01:06:57on the side of the road

01:06:59you have to turn around

01:07:01and avoid going back to your house

01:07:03for at least a week.

01:07:05In other words,

01:07:07something serious could happen.

01:07:09There are countless stories

01:07:11of accidents avoided

01:07:13with this mysterious character.

01:07:15Some even say

01:07:17that they were hit by man

01:07:19There is no concrete proof

01:07:21of the real existence of man

01:07:23driving in the opposite direction.

01:07:25Many experts believe

01:07:27that this legend is just a warning

01:07:29intended to remind people

01:07:31to be careful of those around them

01:07:33and drive carefully.

01:07:35However, the legend persists

01:07:37and continues to be transmitted

01:07:39from generation to generation

01:07:41making it one of the most tenacious urban myths

01:07:43of all time.

01:07:49Hello to you,

01:07:51car owner.

01:07:53I have an important message for you.

01:07:55You see, our cars are like

01:07:57our faithful acolytes,

01:07:59always by our side,

01:08:01even in the most open places.

01:08:03But sometimes we regain our vehicle

01:08:05to discover that unexpected surprises

01:08:07are waiting for us.

01:08:09Try to imagine that you are heading

01:08:11towards your four-wheeled companion

01:08:13and there, a Prospectus

01:08:15that knocks you under the windshield

01:08:17to draw your attention to the windshield.

01:08:19We all went through there,

01:08:21didn't we?

01:08:23Well, hang on to your wheels

01:08:25because the authorities have a new piece of advice for you.

01:08:27And it's a real gem.

01:08:29If you see something on your car

01:08:31that shouldn't be there,

01:08:33don't take it off with your bare hands.

01:08:35Are you intrigued?

01:08:37You see, the police keep an eye

01:08:39on everything that concerns cars

01:08:41and their role is not limited

01:08:43to catching the drivers

01:08:45They are there for us

01:08:47when the time comes to reveal

01:08:49the last tricks of the trade.

01:08:51Take Arlington, in Virginia for example.

01:08:53The authorities have recently noticed

01:08:55an increase in airbag theft

01:08:57on the driver's side.

01:08:59To fight against this madness,

01:09:01the police advised people to park

01:09:03in well-lit areas,

01:09:05to lock their vehicles,

01:09:07to put their valuables at risk

01:09:09and why not add a lock device

01:09:11to the steering wheel as a precaution.

01:09:13The authorities have also discovered

01:09:15a new superpower.

01:09:17Use the camera of your smartphone

01:09:19to take a look inside your vehicle.

01:09:21It's as if they had a X-ray vision

01:09:23or something like that.

01:09:25These cunning people can bypass

01:09:27the confidentiality of the windows of your car

01:09:29and get a clear view of your possessions.

01:09:31All this without even taking the slightest picture.

01:09:33Smartphones nowadays, right?

01:09:35In response,

01:09:37the authorities launched a campaign

01:09:39Hide them and don't show them.

01:09:41They tell everyone to hide their valuables

01:09:43or, by default, to put them away.

01:09:45But wait, that's not all.

01:09:47The police ask us to be careful

01:09:49in the face of a new threat

01:09:51lurking around our vehicles.

01:09:53You know how it goes.

01:09:55Leaves, debris and other objects

01:09:57are often found on our precious cars.

01:09:59Normally, we wouldn't think about it

01:10:01and we would just give our vehicles

01:10:03a quick wipe before

01:10:05going at full speed.

01:10:07However, you should think twice

01:10:09before taking care of them

01:10:11even if it's only to pick up

01:10:13a waste that seems harmless.

01:10:15Why all this mess?

01:10:17Well, let's take a look

01:10:19at an incident that happened

01:10:21in Houston, Texas.

01:10:23Imagine this.

01:10:25A woman, just back from

01:10:27celebrating her birthday

01:10:29in a local restaurant,

01:10:31returns to her car to find

01:10:33a paper towel stuck in her door handle.

01:10:35At first, she didn't pay much attention

01:10:37and took out the paper towel

01:10:39thinking it was just a piece of dirt

01:10:41among so many others.

01:10:43But it turns out that things

01:10:45then took a disturbing turn.

01:10:47Shortly after handling

01:10:49this suspicious paper towel,

01:10:51she began to feel tingling

01:10:53in her fingers.

01:10:55And before she knew it,

01:10:57all her arm was tingling

01:10:59leaving her a little fatigued.

01:11:01She began to have a spinning head

01:11:03and even had trouble breathing.

01:11:05She left at full speed

01:11:07for the hospital,

01:11:09racing against the clock

01:11:11to find out what could have caused

01:11:13such a rush with her health.

01:11:15After 6 endless hours,

01:11:17the doctors finally diagnosed

01:11:19a high poisoning

01:11:21due to an unknown substance.

01:11:23They couldn't identify

01:11:25the exact nature of this substance

01:11:27because the woman only had

01:11:29a small amount in her system.

01:11:31But even this small amount

01:11:33could have been the cause

01:11:35of the attack.

01:11:37Imagine if she had

01:11:39wrapped this paper towel

01:11:41around all her hand.

01:11:43One of these doctors

01:11:45suggested that the incident

01:11:47related to this paper towel

01:11:49could have been an attempt

01:11:51to take part of her car.

01:11:53Wait, what?

01:11:55A kidnapping involving

01:11:57a paper towel and a door?

01:11:59It looks like the bad scenario

01:12:01of the kidnapping

01:12:03has been solved.

01:12:05The police have confirmed

01:12:07that the woman's experience

01:12:09and her symptoms

01:12:11corresponded

01:12:13to other poisoning cases.

01:12:15Of course,

01:12:17there are many other strategies

01:12:19to help you stay safe

01:12:21and your car safe.

01:12:23For example,

01:12:25when it comes to parking

01:12:27or when it comes to

01:12:29parking,

01:12:31the trick is to find the best place.

01:12:33Fortunately,

01:12:35specialists have some advice

01:12:37that will make you a real parking pro

01:12:41at a distance.

01:12:43First, if you have the chance

01:12:45to have a garage,

01:12:47always park your precious vehicle

01:12:49inside. But if you are traveling,

01:12:51it is advisable to find a well-open

01:12:53and well-lit place to park.

01:12:55You want your vehicle to be

01:12:57well-lit so that a shadow

01:12:59or some misdeeds can spread.

01:13:01Now, here is a little trick

01:13:03coming directly from a former burglar.

01:13:05This guy knows all the tricks of the trade.

01:13:07When you park,

01:13:09turn your wheels to the sidewalk.

01:13:11I know, it sounds weird,

01:13:13but trust me,

01:13:15it's worth it.

01:13:17By doing this,

01:13:19you make life more difficult

01:13:21for these inopportune intruders.

01:13:23They will have to perform

01:13:25a thorough inspection.

01:13:27Then, here is an additional advice for you.

01:13:29Try to find a parking

01:13:31that meets the Parkmark standard

01:13:33of the Parking Association.

01:13:35These parking lots are subject

01:13:37to a risk assessment by the police,

01:13:39so you know they are on the right track.

01:13:41With these simple tips,

01:13:43you will park like a pro in no time.

01:13:45Nowadays, there is still a pernicious way

01:13:47for thieves to recover your vehicle,

01:13:49and this involves your precious key.

01:13:51So, let's try to stay careful,

01:13:53first of all,

01:13:55keep your keys well hidden.

01:13:57When you are at home,

01:13:59make sure they are out of sight

01:14:01and far from indiscreet glances.

01:14:03You would not want thieves

01:14:05to have fun fishing

01:14:07with sticks and hooks

01:14:09through the slit of your mailbox,

01:14:11thus taking your keys.

01:14:13Now, let's talk about the keyless opening.

01:14:15You know, these sophisticated cars

01:14:17that unlock themselves

01:14:19with a simple pressure

01:14:21If you still have to press

01:14:23a button on your key to open your car,

01:14:25you do not have a keyless opening.

01:14:27But no worries,

01:14:29we will also cover this subject.

01:14:31Imagine this.

01:14:33You continue your day,

01:14:35taking care of your business,

01:14:37when suddenly a cunning thief

01:14:39arrives with a small device.

01:14:41This sly machine deceives your car

01:14:43by making it believe that your key is right there,

01:14:45unlocking it faster than you can imagine.

01:14:47They can even start the engine

01:14:49and escape into the setting sun

01:14:51with your beloved car.

01:14:53Believe it or not,

01:14:55these cunning thieves

01:14:57only need to be a few meters away

01:14:59from your car key to catch their signal.

01:15:01This means that they can perform their magic

01:15:03even if your key flows gently

01:15:05inside your house,

01:15:07safely.

01:15:09Do not be afraid,

01:15:11because there are some tips

01:15:13to protect your car

01:15:15from a keyless opening

01:15:17and its double,

01:15:19very, very far from your vehicle.

01:15:21Maybe you can put them in a grilled pocket

01:15:23or a sophisticated Faraday bag

01:15:25to block any signal leak.

01:15:27See it as giving your key

01:15:29a small invisible keyhole

01:15:31to protect it from these cunning thieves

01:15:33who sniff the signals.

01:15:35Here is another pro tip.

01:15:37If you decide one day to add

01:15:39a used car to your beloved car,

01:15:41give these keys a little lifting.

01:15:43Reprogramming them will ensure

01:15:45that all the old unpleasant signals

01:15:47or surprises left by the former owner

01:15:49will be erased.

01:15:51To ensure that your car is always safe,

01:15:53we must also address

01:15:55this much less pleasant subject,

01:15:57the fake dealers.

01:15:59These thieves full of resources

01:16:01think they can appropriate

01:16:03your precious vehicle directly in the street.

01:16:05Here are some tips explaining

01:16:07how to keep a long lead

01:16:09on these parking pirates.

01:16:11First of all, keep an eye

01:16:13on the people who seem a little suspicious.

01:16:15You know, those who don't wear

01:16:17nice logos on their trucks

01:16:19or who forgot to put on

01:16:21their work uniforms.

01:16:23If something doesn't seem right to you,

01:16:25don't hesitate to report it immediately.

01:16:27Now I know what you think.

01:16:29But what if I'm wrong

01:16:31and it turns out it's a false alert?

01:16:33We should all be of good faith

01:16:35and no one should blame you

01:16:37if you make mistakes on the person.

01:16:39Better to warn than to heal, right?

01:16:43The Voice of the Future

01:16:45The Voice of the Future

01:16:47The Voice of the Future

01:16:49The Voice of the Future

01:16:51The Voice of the Future

01:16:53In the heart of a dense forest,

01:16:55a person takes a hike in the forest,

01:16:57plunging into the mysterious

01:16:59depths of this wild nature.

01:17:01But it's not an ordinary walk

01:17:03through the woods.

01:17:05She will soon take a strange turn

01:17:07to not say frankly disturbing.

01:17:09Our protagonist,

01:17:11in the gaze, discovers a terrier hidden in the shadows. Curiosity overcomes fear,

01:17:17and our explorer approaches it. It's not just any terrier, it's a fox.

01:17:23And if it was a bad idea, and we had to run away from it?

01:17:26During the happy spring season, when nature is animated by a vibrant energy,

01:17:36the foxes always pursue the complex cycle of life. It is at this time that the foxes

01:17:42seek the comfort of their underground sanctuaries. The rest of the year, when the world around is

01:17:48luxurious, the fox prefers to lean against the sun and spend all his time on the surface,

01:17:53except when the weather is bad. It is in the most unfavorable conditions that he

01:17:59takes refuge in his terrier, sheltered from the bad weather. These fox terriers

01:18:06usually only have a few entrances, sometimes covered with dirt and scattered debris.

01:18:11During the winter months, the foxes dig with diligence new galleries,

01:18:17in anticipation of the coming spring. Sometimes, among the remains of their underground journey,

01:18:22we find remains of dead foxes, witnessing the endless cycle of existence,

01:18:27within these complex underground networks. If we explore the surroundings of a fox terrier,

01:18:36we will notice fresh traces of meals outside the terriers, during the months of April to June.

01:18:41It is at this period, when the foxes have played in the north, the forest of their presence,

01:18:46that we can find remains of their feasts, a certain sign of this new life that is developing.

01:18:51So what do these terriers look like? After all, they are not the only animals that see

01:19:01dens in the forest. Let us now get to the heart of the matter. Fox terriers,

01:19:06impenetrable remains of these spying beings, are generally located in areas where the

01:19:12greenery is abundant, these animals can hide under the branches of a tree,

01:19:16or take refuge under imposing rocks. If you come across a small hollowed hole that seems

01:19:21cut to size for a fox, and that you smell this incomparable aroma, accompanied by other

01:19:27revealing clues such as scattered bones, it is that you have probably discovered a fox den.

01:19:33Alas, my curious friend, there is no infallible recipe to know where these

01:19:42cunning canids choose to set up their den. They have an amazing ability to adapt

01:19:48to various environments, whether it is open meadows, dense forests, or even the pitiful tundra.

01:19:54Imagine a little, the terrier of a fox consists of at least four or five parts. There is the main entrance,

01:20:04the access tunnel, the main den, and a secret room that serves as a reserve for food.

01:20:09Depending on the size of the den, there may be additional rooms to accommodate the entire

01:20:14family of foxes. Now visualize the opening of the den of a fox, the entrance and the

01:20:23access tunnel form a corridor that goes down from one to three meters underground, connecting the

01:20:29outside world to the den that is there. Ah, but that's not all, the foxes,

01:20:35as warned administrators, store all the treasures they have found in their den. Yes,

01:20:41they have their own food cache where they hide all these delicious finds. The number of

01:20:47rooms in the den can vary depending on the size of the den, because these cunning animals

01:20:53make sure that there is enough space to lower and raise their adorable den. They can

01:20:59even dig additional tunnels and create other entrances in case the need would be felt.

01:21:05Now let's talk about culinary affairs. Foxes are warned gourmets who stock

01:21:11large quantities of food, ready to face the winter and the season of love. However,

01:21:17they are not catchers. They usually put aside just what they need for the

01:21:22times to come, given that they do not have the chance to find a fresh prey every day.

01:21:26Bees and fruits often guard their food, while these delectable carcasses are

01:21:32at the center of their gastronomic menu. Are you curious to know if fox burrows are

01:21:40close to each other? If the earth was rich in food and fresh water,

01:21:44you can sometimes find two or three dens in a radius of 25 square kilometers. On the other hand,

01:21:51if resources are scarce, you may have to extend your research to a radius of 50 square kilometers

01:21:57to find a burrow. But the adventure does not stop there. Foxes,

01:22:05loyal to their foggy nature, often have several burrows. They keep their main burrow,

01:22:10often called the native burrow, and the sentimental value that goes with it. In addition,

01:22:16they keep a rescue burrow to face unexpected circumstances. Let's not forget

01:22:21either their ability to appropriate or borrow abandoned burrows. They are

01:22:26smart little ones, aren't they? Now let's talk about these wonderful animals. Foxes

01:22:34are classified into a multitude of species, variations, and sizes scattered throughout the

01:22:39planet. But the star is the red fox, which can be found on all continents,

01:22:44with the exception of the Antarctic glaciers. If most foxes prefer the tranquility of

01:22:52rural landscapes, do not be surprised to see them venture into urban and suburban areas,

01:22:58where their path can cross that of man. Ah, the encounters between fox and man,

01:23:05it's the story of two extremes. Some benevolent souls try to gain the trust of these animals

01:23:11by offering them treats and pampering them. On the other hand, there are those who tremble at

01:23:17the mere sight of a fox, fearing their ferocious and ferocious nature. Now imagine this scenario,

01:23:26what happens if a fox approaches you, or even attacks you? In general, foxes are

01:23:34not a threat to humans, and do not have bad intentions. They prefer to feast on

01:23:39small mammals or hens, reserving their aggressiveness to hunting or their own

01:23:44defense. However, cases of confrontation between humans and foxes have been reported,

01:23:49among which a few incidents. It is therefore essential to know the measures to take if a

01:23:54fox approaches or throws itself on you. Foxes can indeed be domesticated. However,

01:24:02they remain essentially wild, and their acts can be quite unpredictable. They

01:24:08can temporarily embrace captivity, then return to their primary instincts when they feel

01:24:14tackled, threatened, pulled by hunger or simply frightened. Naturally, foxes consider us

01:24:23as potential threats, and it is in our interest to show the same caution.

01:24:28Never try to approach a fox, even if it seems friendly and docile, because its temperament

01:24:34can change in a few seconds and take you by surprise. Avoid sudden movements and resist

01:24:42the desire to approach you, because this could agitate or frighten our fox friend. In most

01:24:48cases, when a fox sees a man nearby, he quickly runs away or hides. However,

01:24:56if you find yourself facing a fox, the best step to take is to take a step back and

01:25:02give him the space he needs. If a fox persists in approaching or if you meet several at

01:25:11the same time, well friend, stay away from them and leave their territory to them. Do not try to

01:25:16approach them or feed them, even less by hand. Let them wander their fox occupations,

01:25:21while you watch them from a distance. If a fox finds itself trapped, for example

01:25:31when entering your garage, it is imperative to stay calm. Avoid raising your voice or causing

01:25:37unnecessary agitation, because this could incite the fox to attack you. On the contrary,

01:25:41remain silent, keep a respectable distance with the animal, and offer it a way to escape.

01:25:48Make sure that the doors and windows are not obstructed, in order to give the fox

01:25:53the freedom it has sought so much. In time, it will escape as quickly as it has become.

01:26:01However, if luck does not smile on you and you find yourself in the unfortunate situation of a fox attack,

01:26:06do not forget to stay calm. Refrain from letting your dog down or chasing it.

01:26:12Let the fox take care of himself. If the latter persists and refuses to back down, a loud noise

01:26:18or a few slaps can be enough to make him run away. And you can now enjoy your walk in the forest.

01:26:32Hmm. From the outside, the surface of this lake looks like the rest of a disaster.

01:26:38Empty tree trunks emerge from the turquoise waters. The lake is surrounded by mountains,

01:26:43which makes it a calm but disturbing place. But those who dare to swim in these dangerous waters

01:26:49will soon discover a whole new world. This is not the beginning of a fairy tale.

01:26:55This is the real story of the Kayndi Lake, located in Sati, Kazakhstan. In 1911, an earthquake

01:27:02caused a major landslide in this place. The valley thus formed was filled with rainwater,

01:27:07practically submerging the forest. The trees located above the waters may seem very sad,

01:27:14but under the surface, they remind of an underwater forest. As the waters are crystalline most of the time,

01:27:21you can always see this fascinating view even from the banks. The lake's icy water complicates things

01:27:27and can sometimes be dangerous. Not to mention the algae, plants and trees that emerge,

01:27:34which can quickly become potentially dangerous obstacles. I like hot and smoky baths,

01:27:40but this boiling lake, which I am going to tell you about, belongs rather to the category of terrifying dreams.

01:27:46It is located on the island of Dominique, in the Caribbean, and its waters have a temperature between 82 and 92 degrees Celsius.

01:27:55And it is only on the edge, because no one has ever dared to reach the middle of the lake to measure its temperature in the center.

01:28:02It is true that the heat can drop from time to time, but you never know when these waters can start boiling again.

01:28:08The place is also dangerous because of the gases it releases, such as carbon dioxide.

01:28:14The smell is not pleasant, believe me, but it is mainly because of the sulfur present in the vaporous air.

01:28:20This lake, apparently calm, also has a dangerous surprise. The Monoun Lake is located in the province of the West, in Cameroon.

01:28:28It is one of the rare erupting lakes on the entire planet, similar to a volcano. And most of the time, it does it without any warning.

01:28:37Its last eruption dates back to 1894, when it caused serious damage.

01:28:42The chemical mechanism of these lakes works like a soda can that is shaken before opening it.

01:28:47Dangerous gases are at the bottom of the waters, so that any disturbance to the surface can trigger their eruption.

01:28:54Lake Natron, in Tanzania, may be beautiful to look at because of its particularly reddish color.

01:29:01But it is certainly not a place where you want to swim.

01:29:04If the water is extremely salty, it also combines with algae, which, by the way, are responsible for the coloration.

01:29:11And it is not even what is most risky.

01:29:14Lake Natron has pH levels so high that they become corrosive.

01:29:18If you wet a piece of dark fabric in this lake, it will soon be devoid of its color.

01:29:24These high levels of acidity can also cause serious problems to the human skin.

01:29:30Everything is not bad for some creatures.

01:29:32Because Lake Natron is the only place where more than 2.5 million little flamingos live.

01:29:37Its acidic and salty waters ensure their survival.

01:29:40So it is not surprising that they like to stay in dams.

01:29:43The risk represented by Lake Nicaragua is less linked to chemistry than to its inhabitants.

01:29:49Located on the border of Costa Rica and Nicaragua, it is the largest freshwater lake in Central America.

01:29:56At first glance, you will not think that it can be dangerous.

01:29:59But because of the bull sharks that live there, I do not advise you to swim there.

01:30:05Sharks tend to be unpredictable and sometimes intimidating creatures.

01:30:09In addition, they are ready to eat everything if necessary.

01:30:12Scientists first believed that this species of shark was only found in this lake.

01:30:16But they quickly discovered that people had seen the same sharks in the Caribbean Sea.

01:30:21These amazing creatures not only cross a distance of more than 193 km to get here.

01:30:26But they can also adapt to fresh water.

01:30:28Which all fish cannot do.

01:30:31The great blue hole of the Belize can seem attractive to divers.

01:30:35I mean that it is a beautiful blue and that it is quite close to the continent.

01:30:38At about 100 km.

01:30:40The problem is that under the surface of these calm waters is a series of complex tunnels.

01:30:45Which contain many types of corals and other wild species.

01:30:49It is these caves that make diving in the great blue hole complicated.

01:30:53In addition, specialists have discovered that by sinking into the waters, creatures are less and less numerous.

01:30:59Why ? Because of a hidden layer of hydrogen sulfide that extends over the entire width of the gulf.

01:31:06As there is no oxygen, no creature can survive at this depth.

01:31:12The Lagnier Lake is the largest lake in the state of Georgia.

01:31:15It welcomes a large number of visitors every year.

01:31:18About 11 million, which is about as much as the Louvre Museum in Paris.

01:31:23Despite its popularity, many accidents occur on this lake and no one knows exactly why.

01:31:29One of the explanations could be under the surface of this mysterious lake.

01:31:34There is a lot of debris and gravel.

01:31:36As well as objects thrown at random.

01:31:39Like boats, garden chairs and even fishing line.

01:31:43All this creates a difficult underwater obstacle course.

01:31:46In addition to a low visibility at the surface of the lake, this place can become dangerous to navigate.

01:31:53The Grand Prismatic Spring, located in Yellowstone National Park.

01:31:57Which extends over the states of Wyoming, Montana and Idaho.

01:32:01Is another example of a lake where one has the impression that someone has done a Photoshop editing with the mountains.

01:32:06It is totally forbidden to swim here.

01:32:09It is 87 ° C in the center.

01:32:12Almost close to boiling.

01:32:14And the outermost ring reaches about 55 ° C.

01:32:17Hence the colors.

01:32:19As the center of the water is too hot for life to develop there.

01:32:22Nothing disturbs the surface.

01:32:25The absence of living organisms creates this bright blue that almost looks like bread.

01:32:32On the small Mediterranean island of Cyprus, there is not much rain during the summer.

01:32:37This is why some water plants become so dry that in some places they are covered with a layer of cooked salt.

01:32:44This is the case of the Salt Lake of Larnaca.

01:32:47Do not be fooled by this sinister landscape.

01:32:50These lands can easily become a trap.

01:32:53Indeed, it is easy to confuse a dry surface with a thin layer of salt that covers water or mud.

01:33:00In addition, under the crust there are salt crystals that can cause skin problems.

01:33:08The hole of Samaesan is one of the most dangerous places to swim in all of Thailand.

01:33:13It is because it is very deep, up to 85 meters, and becomes extremely dark.

01:33:18In some places, when divers go down, they can even reach places where visibility is zero.

01:33:24It is not surprising that many people are disoriented and can no longer find their way up.

01:33:29The largest lake in Africa and the third largest lake in the world is called Lake Victoria.

01:33:35All these waters are not dangerous to humans.

01:33:38But some regions can quickly pose problems.

01:33:41Why ?

01:33:42Partly because it has its own independent weather system.

01:33:46And this makes the weather really unreliable.

01:33:49It can go from clear and sunny to terrible in a few seconds.

01:33:53I mean, who would like to end up swimming in the middle of a storm, right?

01:33:57The Poustoyer Lake is located in Siberia.

01:34:00So I guess I don't need to tell you that these waters are extremely cold.

01:34:05But if you look at the lake, there is nothing extraordinary in these waters.

01:34:09Is it completely true?

01:34:11Most likely not.

01:34:13And people tend to avoid swimming here at all costs, even if they can resist ice water.

01:34:19So what makes the Poustoyer Lake so mysterious and dangerous?

01:34:23Well, nothing seems to want to live here.

01:34:26And scientists have not yet discovered why.

01:34:29They tried to fill the lake with many types of fish and various species of plants to see if they could survive in the water.

01:34:35But the results were disappointing.

01:34:38As we do not know exactly why it is so difficult to survive here, do not rush to get your swimsuit yet.

01:34:44It is preferable that you stay away.

01:34:46Hey, you don't need to tell me twice.
