A small, tropical animal with broad, scaly-looking, bony plates covering the head, shoulders, rump, and long pointed tail. The armadillo’s body has a series of narrow, moveable bands of armor that give the animal flexibility and allow it to roll into a ball to protect itself from enemies. Armadillos are usually the color of the dirt in which they have been digging most recently as they build burrows and search for food. They cross streams by walking across the bottom or swallowing air so that they can float across.
