Earless lizards are two genera of small lizards native to the semi-arid and grassland habitats of the southwestern United States and Mexico. The genus "Cophosaurus" and the genus "Holbrookia" are both characterized by having no external ear openings, presumably to prevent sand from entering the body as they dig.
