The Only Primate That Makes Cheetahs Run For Their Lives! | Wildlife Documentary

[00:00:00]The dust has not yet settled when the cheetah comes to a halt. It is not an elegant stop. It is the kind of immobility the body forces upon itself [music] when the brain realizes, too late, that it has made a catastrophic miscalculation.

[00:00:16]He is at the center of a closing circle.

[00:00:18]Around him, more than 30 baboons move with a silent coordination that defies any simple definition of animal instinct. Some take two steps forward, others flank him. The adult males, with their muzzles thrust forward like bone axes, bear fangs measuring between 2 and 3 [music] inches, canines that even adult leopard rivals have learned to respect. The cheetah looks one way, then the other. His body, refined for a single purpose [music] on this planet, a straight-line chase in wide-open spaces, has no programmed response for this scenario. He was not built for this.

[00:00:57]Every muscle in his body is engineered [music] for speed, not combat. The semi-retractable claws that provide [music] grip during 70-mph turns are virtually useless in a melee [music] fight. The thin bones that reduce his weight to maximize acceleration are now a liability, and the baboons [music] know it. Not the way a general knows a war manual, but in the visceral, ancestral [music] way that animals who have coexisted with predators for tens of millions of years learn to distinguish what can kill alone from what cannot. The cheetah snorts. The baboons [music] do not back down. This is the point where the savanna reveals one of its most brutal truths. Speed and strength are different currencies, and here, in this circle of dust and escalating tension, the currency that matters [music] most is the one the cheetah simply does not carry. The East African [music] savanna at dawn carries a quality of light that photographers chase for years on end. The horizon [music] is the color of weathered copper and the grassland still holds the early morning dew. It is in this setting that a Acinonyx jubatus, the cheetah, begins his day. Unlike the lion who wakes long after the sun is up and the leopard [music] who prefers the shadows of the night, the cheetah is a diurnal hunter out of biological necessity. His eyes lack the tapetum lucidum, the reflective layer that amplifies night vision in nocturnal felines. On the other hand, he possesses a black stripe [music] that runs from the inner corner of each eye down to the edge of his mouth, a structure biologists call tear marks. These function as a natural anti-glare for the intense sunlight, exactly like the eye black Olympic sprinters use during outdoor competitions. The cheetah's body is a statement of evolutionary intent.

[00:02:55]Weighing between 46 and 158 lb, he is the smallest of the big African cats, but weight is deceptive. His spine is exceptionally long and flexible, functioning like a biological spring that compresses and expands during a sprint, [music] extending the length of each stride beyond what limbs alone would allow. During every full galloping cycle, [music] the cheetah has two moments when all four limbs are off the ground simultaneously.

[00:03:26]At maximum extension [music] and maximum contraction, this means that technically, the fastest animal on Earth spends most of a chase airborne. The semi-retractable claws, a unique trait among true felids, act like running cleats, digging into the ground at angles a cat with fully retractable claws could never manage. A top speed of 70 mph is reached in less than 3 seconds from a dead stop, but there is a brutal cost to this specialization. To achieve that speed, the cheetah sacrificed almost everything other predators [music] possess. His bones are thin, which reduces weight and increases acceleration, but it also means [music] a bite from a leopard or a beating from a male baboon can break a leg and deliver a death sentence. His respiratory [music] system is disproportionately large with the heart and lungs occupying space filled by larger jaws in other cats. As a result, the cheetah has the weakest bite force among the big African felids. A lion bites with an estimated force of 570 lb per square inch. A leopard exceeds that number. The cheetah hovers around 400.

[00:04:42]For comparison, an adult human reaches about 115.

[00:04:47]These numbers have direct implications during a confrontation. The cheetah kills his prey by suffocation, clamping down on the trachea in a prolonged bite >> [music] >> that lasts between 10 and 15 minutes. He needs time, and time is [music] exactly what he will not have when the baboons close in. Baboons [music] are a radically different evolutionary experiment. Papio ursinus, the chacma baboon of southern Africa, and Papio cynocephalus, the yellow baboon of the [music] east, are primates from the family Cercopithecidae with an evolutionary history [music] spanning roughly 2 million years in open savanna environments. Where most primates retreated to [music] the trees to escape predators, baboons came down to the ground and stayed. [music] This choice shaped everything about their bodies and behavior. Adult males reach up to 88 lb with shoulders and necks built by decades of interspecies combat.

[00:05:47]The upper canines, which grow continuously throughout their lives, reach up to nearly 3 in in dominant males, outgrowing the canines of a leopard. These teeth are not ornamental.

[00:05:59]They are combat tools tested in regular territorial duels that leave permanent scars on both competitors. But, what makes the baboon truly dangerous is not the individual. [music] It is the troop. A baboon troop is a social structure of a complexity that rivals that of many mammals considered highly intelligent. Troops range [music] from 12 to 200 individuals organized in multi-dimensional hierarchies where males and females have [music] separate rankings that intersect during external conflicts. Research published in the journal Animal Behavior [music] demonstrated that baboons are capable of assessing a predator's threat level and adjusting their collective behavior accordingly. Similar to what animal cognition scholars call calibrated risk assessment. When a predator is identified as a solitary, medium-sized threat, as is the case with a cheetah, the females retreat with the infants while the adult males form a skirmish [music] line. This line is not chaotic.

[00:07:05]It is coordinated and it moves forward.

[00:07:08]>> [music] >> The cheetah encounters baboons more frequently than safari records suggest.

[00:07:13]The reason is simple. Both animals inhabit the same open and wooded savanna ecosystems, [music] frequent the same water sources at the same times, and compete for the same high-density territories of small to medium prey. The trouble for the cheetah begins when he tries to hunt near a troop. Young baboons and females are viable prey for an adult cheetah [music] in the open field where speed decides everything before the males can intervene. Serengeti researchers have documented cheetahs >> [music] >> using ambush strategies lasting up to 40 minutes, waiting for the exact moment a baboon infant wanders far enough from the group's protection. The window of opportunity exists, but it is razor [music] thin. And when the math fails, when the cheetah attacks and fails to secure the kill before the troop reacts, the scenario shifts from a chase to a siege in a matter of [music] seconds.

[00:08:11]The moment a baboon troop decides to counter attack a cheetah is one of the most extraordinary and least filmed spectacles of the African savanna. The behavior begins with specific alarm calls distinct [music] from those used for snakes, eagles, or lions. Studies by primatologists Robert Seyfarth and Dorothy Cheney at the [music] University of Pennsylvania identified that baboons have semantically distinct vocal repertoires for different categories of predators. Functionally, this acts as a rudimentary form of referential language. When the alarm for a medium-sized terrestrial cat is raised, adult males do not flee. They run toward the source of the sound. This reversal of the flight instinct is counterintuitive, and that is precisely why it works so well. The predator expects prey. Instead, he receives a counteroffensive. The reaction time needed to rethink his strategy >> [music] >> is all the baboons need to close the distance. A cheetah caught inside the circle faces a physiological equation for which there is no elegant solution.

[00:09:19]His body temperature during a high-speed chase [music] can reach 106° Fahrenheit, just 1° below the threshold for neurological [music] damage. After a sprint of less than 30 seconds, the animal [music] needs to rest for 15 to 20 minutes before he can react with full efficiency again.

[00:09:37][music] If the baboons encircle him right after a failed hunting attempt, >> [music] >> the cheetah is quite literally at his physiological limit. He has [music] no energy reserves for a prolonged battle.

[00:09:51]The cheetah's natural strategy in any confrontation that is not a straight line chase >> [music] >> is retreat. He runs away. But when the circle is closed, retreating requires breaking through the line of males, and every male poses a real risk of laceration from fangs that can slice through muscle and tendon. The outcome of a direct confrontation [music] between cheetahs and baboon troops rarely involves the death of the cat, but it frequently results in injuries that permanently alter his hunting ability. A cheetah with a deep flank scar caused by a baboon canine can develop muscular asymmetry, reducing his top speed by [music] 10 to 15%. A 10% reduction in the top speed of an Acinonyx jubatus can [music] mean the difference between being a predator with a 70% hunting success rate and an animal struggling [music] to eat regularly.

[00:10:46]Most cheetahs that die of malnutrition were not killed by another predator.

[00:10:51]They were worn down by a series of minor clashes, accumulated injuries, and competition over territory and carcasses. The baboons do not need [music] to kill the cheetah to win the fight. They only need to ensure that the cost of approaching a troop is high enough for the cat to learn to [music] pick different targets. What this clash reveals goes beyond a chance encounter between two animals on an African savanna. It exposes a central truth of evolution. Extreme specialization creates absolute power [music] under specific conditions and real vulnerability outside of them. The cheetah is the most dramatic proof of this principle in [music] the entire African food chain. No living animal on earth can do what he does in the open field, and no animal suffers as much as he does when the open field disappears.

[00:11:42]The baboons, on the other hand, represent the power of a different strategy, adaptability, collective intelligence, and a refusal to play the role of prey that the ecosystem seemed to script for them. The savanna is not a stage of fixed heroes and victims. It is a system under constant renegotiation, where the rules are rewritten every time a cheetah underestimates a troop and a troop decides not to [music] back down.

[00:12:11]The fastest animal in the world is not at the top of this story. He's at the center of it, surrounded, panting, and learning.
