Its tongue can flick out 45 cm (18 in) and whip back and forth about 160 times each minute, nearly three strokes per second, allowing a single anteater to raid up to 200 insect nests in a day and gulp down roughly 35,000 ants and termites. This hyper-fast, sticky tongue lets the giant anteater harvest a massive protein buffet without teeth, turning a slow-moving mammal into a highly efficient insectivore.
It walks on the knuckles of its forefeet, curling its massive front claws out of the way, a gait shared with great apes. This adaptation protects the claws from wear while the animal digs termite mounds, giving it the leverage to pull apart nests with a "hook-and-pull" motion.
Home-range size varies dramatically: in Brazil's Serra da Canastra National Park it can be as small as 2.7 km² (1 sq mi), while in Argentina's Iberá Natural Reserve it expands to 32.5 km² (12.5 sq mi). road mortality that can cut local population growth by half.
The species vanished from Corrientes province for 40 years, only to reappear in 2025 after passive restoration of 150 ha of degraded land. The comeback suggests that simply fencing out livestock and allowing native vegetation to regrow can rebuild ant populations fast enough to lure a top insectivore back into its former range.
Its sense of smell is 40 times stronger than a human's, across its 3.7-km-daily travel range.

In the twilight realm of the tropical forest, the giant anteater emerges as a curious and enigmatic creature, its long, pointed snout twitching with an almost imperceptible sensitivity as it navigates the underbrush with a slow, deliberate gait. With its shaggy, greyish-brown coat and powerful front legs, it moves through the world with a quiet purpose, driven by an insatiable hunger for the ants and termites that constitute its unique and fascinating diet. As it roots out its prey with an extendable, sticky tongue, the giant anteater embodies a remarkable convergence of form and function, a testament to the boundless ingenuity of evolutionary adaptation.
