<Li> Genus † Protamandua (Ameghino 1904) </Li> <P> 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 . </P> <P> 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 . </P> <P> All anteaters have elongated snouts equipped with a thin tongue that can be extended to a length greater than the length of the head; their tube - shaped mouths have lips but no teeth . They use their large, curved foreclaws to tear open ant and termite mounds and for defense, while their dense and long fur protects them from attacks from the insects . All species except the giant anteater have a long prehensile tail . </P>
