Many armadillos are killed when they are run over by cars. Armadillos are protected by plates of bony armor covered with skin. Many armadillos can curl into a ball when threatened by predators. They dig into the earth using their large claws to find food. They use their long tongue to get ants, beetles, termites, worms, grubs, other small animals and eggs.
Armadillos have peg-like teeth.
