<P> Silky anteaters and northern tamanduas extend their ranges as far north as southeastern Mexico, while giant anteaters can be found as far north as Central America . Southern tamanduas range south to Uruguay (giant anteaters did also until their recent extirpation there) and the ranges of all species except the northern tamandua overlap in eastern Brazil . Anteaters were confined to South America, which was formerly an island continent, during most of the Cenozoic Era . Once the Isthmus of Panama formed about three million years ago, however, anteaters invaded Central America as part of the Great American Interchange . </P> <P> Anteater habitats include dry tropical forests, rainforests, grasslands, and savannas . The silky anteater (Cyclopes didactylus) is specialized to an arboreal environment, but the more opportunistic tamanduas find their food both on the ground and in trees, typically in dry forests near streams and lakes . The almost entirely terrestrial giant anteater (Myrmecophaga tridactyla) lives in savannas . </P> <P> The two anteaters of the genus Tamandua, the southern (Tamandua tetradactyla) and the northern tamanduas (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 . </P> <P> 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 . </P>
