Armadillos are the only living mammals that wear such shells.Closely related to anteaters and sloths, armadillos generally have a pointy or shovel-shaped snout and small eyes. They vary widely in size and color, from the 6-inch-long (15-centimeter-long), salmon-colored pink fairy armadillo to the 5-foot-long (1.5-meter-long), dark-brown giant armadillos.
Armadillos live in temperate and warm habitats, including rain forests, grasslands, and semi-deserts. Because of their low metabolic rate and lack of fat stores, cold is their enemy, and spates of intemperate weather can wipe out whole populations.
They have very poor eyesight, and utilize their keen sense of smell to hunt. Strong legs and huge front claws are used for digging, and long, sticky tongues for extracting ants and termites from their tunnels. In addition to bugs, armadillos eat small vertebrates, plants, and some fruit, as well as the occasional carrion meal.
