The Armadillos are small to medium-sized placental mammals with a leathery armor shell. In Spanish, the word armadillo means "little armored one." These mammals originated from South America. The smallest species, the pink fairy armadillo, is the size of a chipmunk. The largest species, the giant armadillo can be the size of a small pig. They are prolific diggers and use their sharp claws to dig for food and to dig their dens. The nine-banded armadillo prefers to build burrows in moist soil near the creeks, streams, and arroyos around which they live and feed. Diets vary but mainly consist of insects, grubs and other invertebrates. Some armadillos feed entirely on ants and termites.
