Edentate, << ee DEHN tayt, >> is the traditional name for a group of mammals that have incomplete sets of teeth or no teeth at all. Anteaters, armadillos, and sloths are the only living edentates. These animals are most common in South America, but they are also found in Central America and parts of North America. The armadillo is the only edentate that lives in the United States. It is found in the South. Edentate means toothless, but armadillos and sloths have back teeth. Some edentates have a hard, bony covering. Others are covered only by hair.
