The only species of armadillo found in North America. The nine-banded armadillo is covered in bony skin plates that form a hard carapace or shell. The shell serves as a suit of armor against predators. Nine flexible rings encircle the shell allowing it to bend. They use their well developed claws and armor covered head to root through the dirt for food. Generally insectivorous with 90 percent of their diet consisting of invertebrates. Their teeth are small and peg like for grinding.
