At first glance, you might not guess the armadillo is a mammal, since most of its body is covered with a bony armor. But it still has fur on its belly and face.

Armadillos eat insects and worms, which they find by digging in the ground with their sharp claws. The bony plates on their back help defend them from predators, especially when they roll into a tight ball to protect their softer body parts.
