Explanation

An armadillo is a four-legged animal with a rounded body that's covered in hard plates. You're most likely to see an armadillo in South or Central America, or possibly in the southern US. Armadillos range from the size of a chipmunk to as big as a large dog. They're nocturnal, so they mostly hunt for food at night and sleep during the day, and are excellent diggers, with very sharp claws. Armadillos are distinctive because of the bony plates that cover them and their protective habit of rolling into a ball. Armadillo is Spanish, the diminutive form of armado, or "armored."
