Anteater

Specialized for ants

Every part of an anteater is built for eating ants and termites in volume:

• Long tubular snout — fits into ant nest tunnels.
• Sticky tongue — up to 60 cm long in the giant anteater, can flick 150 times per minute.
• No teeth — none needed; insects are crushed in a muscular gizzard-like stomach.
• Strong front claws — break open ant mounds and termite cones.
• Walking on knuckles — to protect the long claws (similar to gorillas).

A giant anteater consumes about 35,000 ants and termites per day, visiting hundreds of nests. They never destroy a single nest — they take a partial meal and move on, allowing the colony to recover and remain a future food source.

Four species

Anteaters fall into four species:

• Giant anteater (Myrmecophaga tridactyla) — 2 m long, ground-dwelling, the iconic species.
• Northern tamandua (Tamandua mexicana) — Mexico/Central America, partly arboreal.
• Southern tamandua (Tamandua tetradactyla) — South America, arboreal.
• Silky anteater (Cyclopes didactylus) — small (40 cm), nocturnal, arboreal.

The giant anteater dominates documentary footage; the smaller species are less-seen.

Defense by claws

Despite their gentle demeanor, giant anteaters can be dangerously defensive. When threatened by jaguars or pumas (their main predators), they:

1. Rear up on hind legs, supported by tail.
2. Open powerful front claws (each claw 10 cm long).
3. Strike with extreme force.

There are documented cases of jaguars killed in anteater encounters, and a small number of human fatalities — usually after attempts to corner or harm an anteater. Healthy adult giant anteaters are not casual prey.

Family relations

Anteaters belong to the order Pilosa alongside sloths. Despite the dramatic anatomical differences, the two groups share a common ancestor — both evolved in South America in a separate lineage from most other mammals during that continent’s long isolation.

Together with armadillos (in a separate but related order, Cingulata), they form the Xenarthra group — a uniquely South American mammalian radiation that survived the Great American Biotic Interchange when North and South American faunas mixed.
