Anteater is a common name for the four extant mammal species of the suborder Vermilingua (meaning "worm tongue") commonly known for eating ants and termites. The individual species have other names in English and other languages. Together with the sloths, they are within the order Pilosa. The name "anteater" is also colloquially applied to the unrelated aardvark, numbat, echidnas, pangolins and some members of the Oecobiidae.
Extant species are the giant anteater Myrmecophaga tridactyla, about 1.8 m (5 ft 11 in) 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 (3 ft 11 in) long; and the northern tamandua Tamandua mexicana of similar dimensions.
The anteaters are more closely related to the sloths than they are to any other group of mammals. Their next closest relations are armadillos. There are four extant species in three genera:
There are several extinct genera as well.
Order Pilosa
Anteaters are one of three surviving families of a once diverse group of mammals that occupied South America while it was geographically isolated from an invasion of animals from North America, the other two being the sloths and the armadillos.
At one time, anteaters were assumed to be related to aardvarks and pangolins because of their physical similarities to those animals, but these similarities have since been determined to be not a sign of a common ancestor, but of convergent evolution. All have evolved powerful digging forearms, long tongues, and toothless, tube-like snouts to subsist 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.
