Le rat à crête africain ? Il a toute cette allure mignonne et câline, mais ne vous y trompez pas - il cache un venin très puissant. Oui, vous avez bien lu ! Ce petit gars enduit sa fourrure de toxines provenant de plantes venimeuses, ce qui en fait l'une des menaces les plus sournoises du règne animal. Et il n'est pas le seul à jouer ce jeu - il y a plein d'autres créatures là-bas qui ont l'air adorable mais qui sont dangereuses. Des hérissons épineux aux grenouilles venimeuses, la nature a plein de surprises en réserve.

FunTranscript
00:00Look at this funny african rat.
00:03Oh, he looks so cute.
00:05Well, you're wrong.
00:07He has an asset in his sleeve.
00:09His poison.
00:10To be honest, the only known toxic rodents in the world are these rattlesnakes.
00:15When they feel tickled, they inflate their fur and show off their black and white stripes.
00:21Right in the middle, there are a bunch of special brown hairs with an alveolar texture.
00:26These are not only decorative,
00:29they are full of such a violent poison that they could kill an elephant.
00:33Rats use it as a chemical armor to protect themselves from predators such as hyenas and wild dogs.
00:41East Africa has long known the toxicity of the rattlesnake.
00:46In 2011, researchers discovered that these rats were pulling poison from a certain tree.
00:51Only a captive rat was able to be surprised while performing this poisonous ritual.
00:56At first, we thought it was an isolated fact.
00:59Nevertheless, the researchers continued to observe it.
01:02The team had 25 rats.
01:04They were filmed in a laboratory before proving that it was not a singular fact.
01:09Even if we know them well, these rats apparently have some weak points.
01:13Some of them seem to be more focused on monogamy, or even the sharing of parental tasks.
01:19Monogamy is rare in the animal world, but it is rat practice.
01:23It's pretty fascinating.
01:25But the researchers claim that they need to do more research before confirming the family values of these rodents.
01:32The next on the list is the lorillant.
01:35This creature seems to be the embodiment of everything that is cute, with its small size and its big eyes.
01:41But these animals are not really of the cuddly kind.
01:44And worse, they are the only venomous primates on the planet.
01:48They live in the tropical forests of the south and southeast of Asia.
01:52You may be wondering why they are called lorillants.
01:56When the explorers first encountered them in the 18th century,
02:00they thought that these little creatures were as slow as lazy people.
02:05Of course, they can stay still for hours and move slowly.
02:10But don't be mistaken.
02:12They are perfectly capable of handling themselves when the need is felt.
02:15If you look closely, you will notice an overgrown and overgrown spot on the inside of their forearms.
02:21This is the brachial gland.
02:23And it secretes a seriously nauseating oil.
02:26When the lorillants feel threatened, they lick this gland,
02:30mixing their saliva with this oil to create a venomous solution.
02:34And when they bite another animal, this venom penetrates directly into the enemy's blood system.
02:39This bite is quite cruel.
02:41It is capable of killing small animals and other insects and causing serious problems in humans.
02:47Suddenly, these big eyes no longer seem so innocent.
02:50In the world of lorillants, males fight for females.
02:53Females fight to protect their young.
02:55And everyone fights to defend their territory.
02:58This venom is useful in such confrontations.
03:01Here, the mothers use their venom cleverly.
03:04Before going out to look for something to nibble on,
03:06they lick their brachial glands and bathe their babies.
03:09This transfers the venom to the fur of the young
03:12and acts as a warning for potential predators.
03:15The next animal is the sand cat.
03:17Meow, this kind of cat lives in the desert.
03:20Unlike other cats, they have made this environment their home.
03:25To begin with, they have the ultimate shoes to walk in the desert.
03:29A thick fur on their paws and even between their toes.
03:33They also enjoy an integrated isolation against extreme temperature variations,
03:39from 50 degrees during the day to 0 degrees at night.
03:44They even grow winter coats,
03:46whose hairs can reach 5 cm long.
03:51Sand cats can spend weeks without drinking a single drop of water.
03:55They draw all the water they need from the prey they nibble on.
03:58In terms of hunting, these sand cats, apparently so cute,
04:02unleash the predator sleeping in them.
04:05Forget their adorable cat aura, these felines are ferocious.
04:09They are not difficult to feed either,
04:11and feed on small rodents, birds or insects.
04:15Oh, and they even prey on venomous vipers.
04:18In addition, if they get more than they can eat,
04:21they hide their extra food in the sand for a small midnight snack.
04:26Their secret weapon is an extremely thin web.
04:30They do not leave footprints and make no noise when they approach their prey.
04:36Here is a sea conch, a kind of sea snail, but with a twist.
04:41They have vivid and colorful patterns on the surface of their shells.
04:45And they are not only pretty to look at, they also have a formidable venom.
04:50Armed with an adapted radula and a venom gland,
04:53sea conches are among the most acquired hunters in the oceans.
04:57They use this tooth, similar to a harpoon,
05:00to project a venomous attack on their prey, paralyzing it before eating it.
05:05Speaking of venom, that of sea conches is the same as a cocktail.
05:09It contains a mixture of toxins with different effects.
05:13Some of the largest species of sea conches can inflict a sting that is not only serious,
05:18but can even be fatal to humans.
05:20However, their venom also helps us solve some medical problems.
05:24A fifth relatively cute animal, albeit dangerous, is the millipede.
05:29These creatures have two pairs of articulated legs on most segments of their body.
05:34Each of these two-legged segments is made up of two simpler segments that combine.
05:39Imagine a team with an elongated, cylindrical or flattened body,
05:43generally comprising more than twenty segments.
05:46But millipedes are the shortest rebels in the band,
05:50which allows them to roll in tight balls.
05:54In 2021, a new species was discovered that had more than 1,300 legs.
05:59If you dive into the world of myriapods, you will find about 12,000 different species.
06:05Many of them are generally harmless to us, but be careful.
06:10Some of them could well be in your house or your garden.
06:16The sixth animal is the pitohui bicolor.
06:19It is a bird found in New Guinea.
06:21It stands out as one of the rare birds known for its toxicity,
06:25with poison in its skin, feathers and other tissues.
06:29This toxin comes from its diet and serves as a defense against predators and parasites.
06:35It is interesting to note that the resemblance it maintains with other toxic pitohui
06:40is a perfect example of converging evolution.
06:43When unrelated species develop similar traits due to comparable environmental pressure.
06:49In this case, different toxic pitohui independently developed similar traits as a form of protection.
06:56The pitohui bicolor also has a mullerian mimicry.
07:00It is a phenomenon during which harmful or venomous species evolve to resemble each other.
07:05In simpler terms, it is like a group of toxic friends who would all dress the same
07:10so that everyone knows that it is better to avoid them.
07:13In addition, non-venomous species imitate the appearance of the pitohui bicolor
07:18in a phenomenon known as Batesian mimicry.
07:21It is when harmless or less dangerous species evolve to resemble a more ferocious or toxic species
07:28in order to enjoy the same protection against predators.
07:31In this case, other birds reproduce the appearance of the pitohui bicolor,
07:36although they do not have the same defenses.
07:39Thus, an harmless bird wears a venomous costume to ward off potential threats.
07:45Ornithorhynchs have an adorable look with their thick fur and their duck beak.
07:50But you don't want to rub yourself with them either.
07:53Especially at the end of winter, when the male ornithorhynchs become a little aggressive.
07:57They fight for the females and use the vicious ergos on their legs
08:02to inject their venom during the confrontation.
08:04In 1801, a biologist thought that these spurs were used to keep the females in place during mating.
08:10But he was wrong.
08:11These creatures are more interested in insect larvae than in any romance.
08:15However, the end of winter is a whole other story.
08:19Males fight, inject their venom and the losers are paralyzed.
08:23There have been cases where they were even caught by humans.
08:27But fortunately, none of them were deadly.
08:29If an ornithorhynch decides to bite you, even morphine will not relieve the effects
08:34and doctors may need to remove the spurs from your wound by hand.
08:38Ouch!
08:40Also pay attention to globefish.
08:42They may be adorable, but they are the second most toxic vertebrae in the world.
08:47Their liver, their eyes and sometimes their skin contain tetrodotoxin.
08:52It is a substance that gives them an infected taste and can be deadly to fish.
08:56They also pose a serious threat to us,
08:59because this toxin is up to 1,200 times more violent than cyanide.
09:04A single globefish contains enough toxins to kill about 30 adults
09:08and there is no known antidote.
09:10Despite this danger, some Japanese consider the flesh of the globefish as a refinement,
09:15called fugu.
09:18The chefs trained to this effect are perfectly aware that a slip of the tongue
09:22could easily shut down their shop.
09:24This is why not everyone is allowed to prepare this dish.
