The giant anteater (Myrmecophaga tridactyla) is the largest of the four anteater species, reaching up to 2.1 meters from snout to tail, and is found across a broad range of habitats in Central and South America, from dry grasslands and savannas to tropical forests. It has no teeth; instead, its tongue can extend roughly 60 centimeters and carries dense, backward-pointing spines coated in sticky saliva, allowing it to consume tens of thousands of ants and termites in a single day without destroying the mounds it feeds from.
Listed as Vulnerable on the IUCN Red List, the giant anteater has disappeared from much of its historical range and populations continue to decline. The primary threats are habitat loss driven by agricultural expansion and fire, both accidental and deliberately set to clear land, along with road collisions and hunting. In Brazil's Cerrado, one of the world's most biodiverse savannas, giant anteaters are among the animals most frequently killed on roads. Their slow reproductive rate, producing a single offspring every one to two years, means populations recover slowly once numbers fall.
Giant anteaters reach up to 7 feet from snout to tail tip and weigh between 60 and 140 pounds, making them the largest of the four anteater species. They use their 2-foot tongue to raid up to 200 termite and ant mounds each day across the savannas and grasslands of Central and South America.
Giant anteaters locate colonies using their powerful sense of smell, then tear open mounds with curved front claws and flick their tongue up to 150 times per minute to collect insects. They spend only about 40 seconds at each mound to avoid soldier ant bites, moving through dozens of sites in a single foraging session.
Giant anteaters range from Honduras south through Central America and across much of South America, with the Brazilian Cerrado and Venezuela's Llanos grasslands holding the largest remaining populations. They occupy savannas, dry forests, and wetlands, avoiding dense rainforest interiors where termite mounds are less accessible.
The IUCN Red List classifies the giant anteater as Vulnerable primarily because of habitat loss from agricultural expansion in the Cerrado and Pantanal, road collisions, and wildfires, which are a leading direct cause of death. Hunters in some regions also target them, and their slow reproductive rate, one pup per year, limits population recovery.
A cornered giant anteater rises on its hind legs, braces with its tail, and swings its forelimbs, delivering slashing blows with claws that can reach four inches long and are strong enough to tear open concrete-hard termite mounds. Even pumas and jaguars, their primary predators, can be seriously injured by this defense.
A mother carries her single pup on her back for up to a year, positioning it so the pup's stripe aligns with hers, which may provide camouflage by disrupting the outline of both animals. The pup begins foraging independently around that first year but stays near its mother for several more months.
