Armadillos possess a characteristic protective armor that consists of the shield on the head; a small shield between the ears on the back of the neck; and a carapace that protects the shoulders, back, sides, and rump. The carapace has 6 to 8 movable bands. This species has more hair than most armadillos. The hairs project from between the scales of the body armor, and the limbs and belly are covered with whitish or light brown hairs. The male is generally larger than the female, and both sexes are heavier in the winter due to a thick layer of fat under the skin (Montgomery, 1985; Nowak, 1997).
