Extant species comprise the Giant Anteater Myrmecophaga tridactyla, about 1.8 m (6 ft) long including the tail; the Silky Anteater Cyclopes didactylus, about 35 cm (14 in.) long; the Southern Tamandua or Collared Anteater Tamandua tetradactyla, about 1.2 m (4 ft) long; and the Northern Tamandua Tamandua mexicana of similar dimensions.
Anteaters eat ants, termites and soft-bodied grubs. Using the long, sharp claws on their forelimbs, they open insect colonies and tree trunks. They then use the tongue to collect the eggs, larvae, and adult insects. The salivary glands secrete sticky saliva during feeding that coats the tongue. They only stay at one ant colony for a short period of time to avoid soldier ants, but giant anteaters can consume a few thousand insects in minutes. The tongue is attached to the sternum and moves very quickly, flicking 150 times per minute. They will eat fruit and birds' eggs on occasion.
The Giant Anteater and regular anteaters have no teeth. Their physical digestion is aided by the pebbles and debris that they consume when they ingest insects.
The giant Anteater lives above ground, not burrowing underground like armadillos or aardvarks. The anteater finds a place to sleep, curls up, and covers itself with its bushy tail. Since the anteater is a very solitary animal, it can be easily awoken. When attacked, it can defend itself with its sabre-like anterior claws. The female produces one offspring per birth. During much of its first year of life, a young Anteater will ride on its mother's back. It is generally acknowledged that giant Anteaters have a poor sense of sight but a keen sense of smell. Their sense of smell has been estimated to be some 40 times more sensitive than that of humans.
The name of the species, tridactyla, comes from "tri" and "dactylos", which is Greek for "three fingers". However, giant Anteaters actually have five toes on each paw (the fifth is vestigial). The name probably came about because only three of the front toes have prominent claws and can be easily seen. Giant Anteaters rarely make sounds. When they do it is mostly when they are young; the sound is a high-pitched, shrilly grunt noise. A baby that has fallen off his mother's back will grunt to its mother either to remind her that it has fallen off or to simply instruct her where it is or to get her attention.
The two Anteaters of the genus Tamandua, the Southern Tamandua (Tamandua tetradactyla) and the Northern Tamandua (Tamandua mexicana), are much smaller than the Giant Anteater, and differ essentially from it in their habits, being mainly arboreal. They inhabit the dense primeval forests of South and Central America. The usual colour is yellowish-white, with a broad black lateral band, covering nearly the whole of the side of the body.The silky Anteater (Cyclopes didactylus) is a native of the hottest parts of South and Central America, and about the size of a cat, of a general yellowish color, and exclusively arboreal in its habits.
Both the tamanduas and the silky Anteater possess partially prehensile tails.
At one time, it was assumed that anteaters were related to aardvarks and pangolins because of their physical similarities to those animals, but it has since been determined that these similarities are not a sign of a common ancestor, but of convergent evolution. All have evolved powerful digging forearms and long tongues and toothless tube-like snouts in order to make a living by raiding termite mounds. This similarity is the reason aardvarks are also commonly called "anteaters"; the pangolin has been called the "scaly anteater"; and the word "antbear" is a common term for both the aardvark and the giant anteater.
Anteaters are known to inhabit the Amazon Rainforest.
The Anteaters are more closely related to the sloths than they are to any other group of mammals, even to the armadillos, their next closest relations. There are three genera still living: the Giant Anteater, the Silky Anteater, and the Northern and Southern Tamandua anteaters, but there are also several extinct genera.
