Quick answer
A small mammal covered in hard, bony plates that can roll into a ball for protection.
An armadillo is a small mammal from the Americas whose back is covered with hard, bony plates, like armor. Many kinds can roll up into a ball when they are afraid, and others dig a hole to hide in. An armadillo has a long snout, strong claws for digging and a poor sense of sight. It eats insects, grubs and small animals. The name comes from Spanish and means little armored one.
