Les fourmis peuvent être minuscules, mais elles sont bien plus terrifiantes que vous ne le pensez ! Certaines espèces peuvent anéantir des écosystèmes entiers, tandis que d'autres possèdent un venin qui peut vous laisser dans une douleur intense — ou pire. Il existe même des « fourmis zombies » contrôlées par un champignon manipulateur d'esprit qui les force à grimper en hauteur pour répandre des spores. Les fourmis de feu ? Elles se ruent, piquent à l'unisson, et n'arrêtent pas d'attaquer tant que vous n'êtes pas couvert de papules brûlantes. De plus, elles surpassent les humains en nombre par des quadrillions, donc si elles décidaient un jour de prendre le contrôle, nous n'aurions aucune chance. En gros, respectez les fourmis... ou vous le regretterez ! Animation créée par Sympa.

00:00Statistically, 3% of hospital amputations performed by experienced surgeons
00:06result in the amputation of the wrong limb.
00:09But this is what happens in the human world,
00:11ants manage in one way or another to do it correctly,
00:14even without attending a medical school.
00:17Researchers have recently made a revolutionary discovery
00:20concerning the medical capabilities of Florida's Carpenter ants.
00:24They observed these ants perform amputations on their injured colony members,
00:29thus marking the first known case of such behavior in the animal kingdom.
00:33The study revealed that ants sort out injuries
00:36and adapt treatments by amputating the legs depending on the severity of the injury.
00:42The ants in question engage in these amputation procedures
00:45after having suffered injuries during battles with neighboring ant colonies.
00:50According to specialists, ants are able to correctly diagnose injuries
00:55and decide whether amputation is necessary for survival.
00:58The injured ants voluntarily participate in the process,
01:01demonstrating a unique form of cooperation within the colony of ants.
01:06Although the exact reasons for this behavior remain obscure,
01:09researchers hypothesize that ants that undergo amputations
01:13have a higher chance of survival compared to those with untreated injuries.
01:18The study also revealed that other species of Carpenter ants
01:22could have a similar amputation behavior,
01:25indicating that this medical treatment could be more widespread in the world of ants
01:29than previously thought.
01:32Scientists hope to further explore the implications of these discoveries,
01:36including the ability of ants to feel physical discomfort
01:39and the other strategies they could have to treat injuries.
01:44If ants undergo surgery, there must be nurses among the ants, right?
01:49Well, the Matabele ants are a bit like the nurses of the insect world
01:54since they save and treat their injured companions after battles with termites.
01:58These ants are native to Africa and do not hesitate to face biting termite soldiers
02:03in their quest for food.
02:06They bring their injured comrades home after the raids,
02:09but the rescue does not stop there.
02:13Once back in the nest, the ants recover to treat the injured,
02:17using their jaws and legs before holding the injured member in place
02:22and licking the wound for up to four minutes at a time.
02:25Ants do not help their friends only out of kindness.
02:29It turns out that these rescues are essential to the survival of injured ants.
02:33Up to 91% die within 24 hours if they are not treated.
02:39Researchers have discovered that licking behavior
02:42could help prevent infections and improve survival chances.
02:47While humans cannot walk more than a few steps from home without consulting Google Maps,
02:52ants use the position of the sun and visual memories of their environment
02:57to guide themselves towards their nest, while walking backwards with heavy loads of food.
03:02Research reveals that ants are not only skilled navigators,
03:06but also masters in the art of adapting to their environment in a creative way.
03:11It was previously thought that ants had two distinct reflexes guiding their movements,
03:16but it has been shown that they strategically look behind them
03:19and use the position of the sun to define their trajectory by walking backwards.
03:24Basically, it's as if ants had their own GPS system,
03:27which is impressive given the size of their brains.
03:30And yes, size does not count when it comes to intelligence.
03:35In addition, trap-jaw ants have proven to have a surprising turn in their sleeves against predators.
03:42These fast and ferocious ants can actually propel themselves into the air
03:46by using their powerful jaws to escape threats.
03:49Researchers observed this behavior in trap-jaw ants
03:53when they encountered lion ant larvae building traps
03:57and found that this unique evasion mechanism considerably increased their chances of survival.
04:05The friendly relationship between ants and trap-jaw ants has fascinated scientists for a long time.
04:11Although these two insects are as different day and night,
04:15they have joined forces to guarantee their mutual success,
04:18in the image of the ultimate dynamic duo in the insect world.
04:22Their partnership illustrates mutualism,
04:25a sophisticated term to describe a giving-giving relationship where everyone is a winner.
04:30Ants play the role of bodyguards for trap-jaw ants,
04:33protecting them from annoying predators and parasites,
04:36while taking care of what they never lack of food.
04:39In return, trap-jaw ants prepare a delicious sweet manna so that ants can enjoy it,
04:44a bit like a Spanish insect inn.
04:46One of the advantages of being friends with an ant
04:49is to benefit from personal protection available at all hours of the day and night.
04:55Thanks to their impressive jaws,
04:57ants make troublemakers flee who take on their trap-jaw friends.
05:02Some species of ants go even further by taking the trap-jaw ants under their wings,
05:07or their paws,
05:08and by moving them to safer places.
05:11Trap-jaw ants may not have the best taste in vegetable meals,
05:15but they know how to turn it into a delicious treat for their ant friends.
05:20By turning vegetable sugars into honey,
05:23trap-jaw ants offer ants a delicious,
05:27rich in energy and essential for them to continue their journey.
05:31Ants will do anything to find their trap-jaw friends
05:34and provide them with this nutritious sweetness.
05:37Ants and trap-jaw ants do not just nibble together,
05:41they are also masters of communication.
05:43Thanks to special chemical signals,
05:45ants guide each other to the sources of food
05:49and warn of imminent threats.
05:52They even exchange signals with their trap-jaw friends,
05:55sometimes giving them a little caress with their antennas
05:58to stimulate the production of honey.
06:00Trap-jaw ants are not content with just lying in the sun.
06:03They are proactive members of this insect copulation system.
06:07They listen to the signals of the ants
06:09and adjust their eating habits accordingly.
06:13They can even pack their bags and move
06:16if the ants indicate that it is time to change scenery.
06:20Ants may not produce honey as trap-jaw ants do,
06:24but although they are insects,
06:26they can produce milk like all mammals.
06:29Who knows, maybe one day we will have
06:31ant milk cans at Starbucks.
06:33I'm kidding.
06:36Until recently, most researchers thought
06:39they knew almost everything there was to know about ants,
06:42until they decided to take a closer look at their nymphs.
06:46Scientists have observed ant colonies for more than a century,
06:50fascinated by the way ants work together
06:53like a great superorganism.
06:55But despite all the attention to the ants' intense activities,
06:58researchers have not really focused on the pupal stage.
07:02It is at this moment that ants transform
07:05from larvae to fully developed adults.
07:08In a recent study, scientists revealed
07:11that ant nymphs play a crucial role in colonies
07:14by producing a substance similar to milk
07:17that feeds the rest of the ants.
07:19This discovery was surprising
07:21because secretions similar to milk
07:23have been found in at least one species
07:26of each of the five main ant subspecies.
07:29Thus, this amazing discovery suggests
07:32that there could be many more species of ants
07:35that produce their own milk.
07:37And the milk-making process
07:39could have taken birth early
07:41in the evolution of all ants.
07:45Trust me,
07:46you don't want to be in bad terms with ants,
07:49otherwise they could decorate their house with your head.
07:52I know, it sounds crazy,
07:54but here's the thing.
07:55Ants really use their opponents' heads
07:58to decorate their homes.
08:00For 60 years,
08:01scientists have been intrigued
08:03by the behavior of a small ant
08:05called Formica archboldi.
08:07These little guys love to twist their nests
08:09with trap-jawed ant skulls
08:11that are armed to the teeth
08:13with venomous darts
08:15and massive clacking jaws.
08:17Despite the difficulties,
08:18Formica archboldi ants in Florida
08:20are experts at killing their biggest adversaries
08:23and taking control of their heads.
08:25How do they do it, you ask?
08:27Well,
08:28it all depends on their rapid and effective acid pulverization.
08:32It turns out that Formica archboldi ants
08:35seem to have a taste for some specific
08:37trap-jawed ant species.
08:40By imitating the smell of their prey,
08:42these headhunters have found a clever way
08:44to dominate them in combat.
08:46But why do they collect exactly their enemies' heads?
08:49Some experts think that this could be a way
08:52to camouflage trap-jawed ants
08:54that manipulate entire colonies of ants.
08:57The small Formica archboldi ants
08:58have impressive skills
09:00in the construction of nests
09:02and can create nests a thousand times bigger than themselves.
09:05They build their homes
09:07by carefully pulling the leaves of the trees together
09:09and fixing them with silk produced by their larvae.
09:12To start their construction project,
09:14the ants choose a tree branch
09:16that will suit their nest.
09:18Then they gather around the leaves
09:21and start pulling them together
09:23until they can form a solid structure.
09:26Once the leaves are in place,
09:28it's time for the ant larvae to shine.
09:31Adult ants carefully transport the larvae
09:35to the spaces between the leaves
09:37where they use their silk production capacity
09:40to glue everything together.
