Si vous rencontrez un serpent sur le sentier, essayez d'abord de rester calme. La plupart des serpents ne vous dérangeront pas si vous ne les dérangez pas. Reculez lentement et laissez-lui de l'espace. Si vous devez passer, assurez-vous de laisser beaucoup de place au serpent et de le contourner. Évitez les mouvements brusques ou de surprendre le serpent, et si vous n'êtes pas sûr du type de serpent, il est préférable de rester prudent et de garder vos distances. Enfin, si vous êtes mordu, essayez de vous souvenir de l'apparence du serpent pour aider les professionnels de la santé à vous soigner efficacement. Animation créée par Sympa.

00:00This black snake with a menacing look won't do you any harm. It doesn't have a tail.
00:06You may have mistakenly thought that this creature was just a black mamba, but it's just an harmless color.
00:13There is a characteristic sign that can help you determine if a snake is really dangerous.
00:19Species without tails don't have a venom distribution mechanism.
00:23Therefore, their bites won't do you much harm.
00:27But if you see a snake with tails, then you are really in danger.
00:33If you come across a snake, it is better to leave the area and ask for help from a fauna professional to identify the reptile.
00:40Here are some tips to help you distinguish the two types.
00:43Observe their behavior, their habits of nesting and their habitats.
00:48Some snakes can shake their tails as a warning.
00:51In addition, venomous snakes usually have triangular heads compared to non-venomous snakes with rounded heads.
01:04It's time for a little optical illusion. Can you spot a snake here?
01:08You'd better be careful because a boomslang is hiding in this tree.
01:12This insatiable reptile has mastered the art of camouflage and he likes to pretend to be a branch.
01:18In addition, boomslangs may not have the best odor, but they compensate for this by their ability to detect chemical compounds in the air.
01:27By using their tongue, they gather smell molecules and press them against the sensory receptors of their mouths.
01:34This snake is venomous. Just look at its claws.
01:38However, when it doesn't intend to use it, the snake just has to carefully fold its claws back.
01:48Boomslang snakes and humans have something in common.
01:51Both have a quantity of accessories made of keratin in their bodies.
01:55Humans' nails and hair are made of keratin and the boomslang is also made of it.
02:01The characteristic sound produced by these sinuous creatures is similar to the sound that we humans can make when we rub our nails against each other.
02:10But these reptiles do it extremely fast, so that it sounds almost like a whistle.
02:17Every time these snakes moan, they add a new segment to their sonnets.
02:22But it's not as if the older a snake was, the more segments it would have.
02:26Their sonnets can wear out or break, just like our nails.
02:30Boomslangs, as well as many other snakes, have an internal ear with a unique structure that does not include a tympanum.
02:37This means that they cannot capture the sounds of the air as we do.
02:41Instead, their internal ear is connected to their jaw, and they use this mechanism to feel the vibrations.
02:49Biologists are still trying to determine whether these snakes detect changes in environmental pressure or mechanical vibrations in their bodies.
03:00They are also quite selective eaters.
03:03Boomslang snakes do not eat only when they are hungry, and adults usually wait about two weeks between each meal.
03:10The time they wait can vary depending on the frugality of their last meal.
03:14These sneaky hunters usually hunt mice, rats, squirrels and rabbits.
03:20But they will not refuse a small bird if they manage to catch one.
03:25Snakes have juvenile sonnets.
03:28However, they tend to have a more robust appetite, sometimes eating up to once a week.
03:36Now, look at their huge jaws.
03:39They are the same as hypodermic needles, hollow and sharp, allowing them to inject their venom.
03:45What is very practical is that these jaws are articulated and lie flat against the upper jaw of the snake when its mouth is closed,
03:53so as not to spread perpendicularly only when it strikes.
03:58Mokasindo, as they are called, owe this name to the white color inside their mouths, which they exhibit when they feel threatened.
04:07These semi-aquatic snakes move effortlessly both in water and on land, which is also why they have this nickname.
04:15With thermosensitive faucets nestled between their eyes and nostrils,
04:19they have an extraordinary ability to detect the smallest variations in temperature and focus precisely on their potential prey.
04:28It is rare for Mokasindo to attack humans.
04:31They rather reserve their venom to respond to a provocation.
04:35Here is some advice on how to distinguish non-venomous water snakes from their dangerous counterparts.
04:40While water snakes display an elongated silhouette, Mokasindo have a heavier and more robust presence.
04:47Another difference is that water snakes have elongated tails and heads and are proportioned to their neck,
04:53unlike the large and thick head of a Mokasin.
04:56The pupils of water snakes are round and differ from vertical pupils, similar to those of cats, Mokasins.
05:04In addition, non-venomous snakes do not have the characteristic facial faucets of vipers that Mokasindos have.
05:12When they feel in danger, non-venomous water snakes resort to an ingenious tactic to imitate their venomous cousins.
05:19By flattening their bodies and heads, they aspire to appear more massive, thus resembling Mokasindos.
05:26However, a keen eye can tell the difference.
05:30Here, the flattened head of the water snake takes a triangular shape, distinct from the robust and thick head of a Mokasin.
05:41Here is another venomous star among all, the copper snake.
05:45Their muscles recall the smell of cucumber, and their venom is quite particular too.
05:50Would you be in trouble if this snake bit you?
05:53Yes, absolutely. Does this venom help to cure deadly infections?
05:57Well, in a way, it is not a totally proven fact at the moment.
06:02But researchers have been testing this theory for a long time, and they have noticed that the venom of the copper snake could,
06:09if it were not to cure serious conditions, slow down their progression.
06:13However, they are the most venomous water snakes of all the snakes of the United States,
06:18although antivenin for water snakes is not always necessary.
06:22The copper snakes are known for their unaggressive nature, because they are shy and discreet creatures.
06:28They represent less than 1% of snake bites in America.
06:32Their venom is a powerful neurotoxin that paralyzes the nerves, and because of their small teeth,
06:37they have to chew their prey to inject the venom.
06:40When they feel threatened, the copper snake rolls up the end of its tail to deceive its attacker on the location of its head.
06:49The mysterious and fascinating black mamba made its kingdom of the rocky savannah and wandered near the thermal springs.
06:57With a range of colors ranging from gray to dark brown, it owes its name to the dark interior of its mouth.
07:03Black mambas are among the fastest snakes in the world, reaching speeds of 15 to 20 km per hour on a flat surface.
07:12Despite its terrible reputation, unprovoked attacks on humans remain to be proven,
07:17and this snake is actually responsible for a small number of deadly incidents each year.
07:23The vipers of the pyramids have the fascinating ability to produce a sound that gives goosebumps.
07:30Accompanied by an impressive demonstration, the unique shape of its scales allows it to create a whistling or a prolonged grunting,
07:38while it moves in a particularly terrifying way.
07:42These sounds serve as a clear warning to anyone who would be in immediate proximity to the snake.
07:49Despite the many victims that can be imputed to it, without any treatment,
07:53the bites of the vipers of the pyramids are only deadly in less than 10% of cases.
07:58This strongly contrasts with the royal cobra and the black mamba, whose untreated bites are much more deadly.
08:04The vipers of the pyramids are known for their extreme aggressiveness and their lightning strikes,
08:09which make some of the snakes the most alive and the most unpredictable in the world.
08:16When you walk in nature, remember not to disturb the snakes you meet there, even if they no longer seem completely alive to you.
08:24Some rusted snakes act like loposomes and can attack if they are disturbed.
08:29If you see one, give it some space.
08:32As far as snakes are concerned, they are generally quite shy and will not bother you unless you feel threatened.
08:39Trying to catch or hit a snake is a must, because that is when most bites occur.
08:46And do not let yourself be abused by their size, even the smallest snakes can be dangerous.
08:51Thus, baby brown snakes even nest with venom, so it is preferable to admire them from a distance.
08:58Every year, more than 7,000 Americans are victims of snake bites,
09:03often due to ill-intentioned attempts to manipulate or fight them.
09:07It is crucial not to do anything about it and to seek emergency medical help in the event of a bite.
09:13Understanding how to differentiate venomous snakes from non-venomous snakes is the key to evaluating potential risks.
09:20Contact a professional if you are not sure of the exact nature of a snake
09:25and never fully handle one, even if it seems harmless.
