About the Giant Anteater

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.

Things worth knowing

  • The giant anteater's claws can reach up to 10 centimeters in length and are powerful enough to tear open concrete-hard termite mounds; on open ground, the animal walks on its knuckles to keep those claws sharp.
  • A giant anteater's core body temperature of around 33 degrees Celsius is one of the lowest recorded among placental mammals, an adaptation that may help offset the low nutritional value of its diet.
  • Giant anteater cubs ride on their mother's back for up to a year, and their fur markings align with their mother's shoulder stripe, making the pair appear as a single animal to predators.
  • Despite their slow appearance, giant anteaters can sprint at up to 50 kilometers per hour for short distances when threatened.
  • They have a highly developed sense of smell estimated to be roughly 40 times more acute than that of a human, which they rely on almost entirely since their eyesight is poor.
  • Giant anteaters are solitary and cover large home ranges, with individuals in the Brazilian Cerrado tracked traversing areas of up to 9,000 hectares according to studies cited by the IUCN.

Challenges the Giant Anteater Is Facing

high threat

Grassland fires

Anteaters are slow and cannot escape fast-moving fire, and the Pantanal fires killed them in large numbers.

high threat

Roadkill

Highways through the Cerrado and Pantanal kill anteaters constantly, and vehicle collision is a leading recorded cause of death.

medium threat

Grassland converted

Cerrado cleared for soy and cattle removes the termite mounds and ant nests the species lives on.

medium threat

Hunted and killed on sight

Anteaters are hunted for meat in parts of the range and killed out of fear in others.

Common questions

Questions people ask about the Giant Anteater

Is the Giant Anteater endangered?

Not in the strict sense. The Giant Anteater is listed as Vulnerable on the IUCN Red List, the first of the three threatened categories and the one below Endangered. It qualifies on a decline of 30% or more, or on a population under 10,000 mature individuals.

How big is a giant anteater?

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.

How does a giant anteater find and eat termites and ants?

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.

Where do giant anteaters live in the wild?

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.

Why is the giant anteater listed as Vulnerable, and what are the main threats?

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.

How does a giant anteater defend itself against predators like pumas and jaguars?

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.

How do giant anteaters raise their young?

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.
