Color variations of the earless lizard
About this image:
The earless lizard of White Sands National Monument isn't really really earless: It lacks an obvious external ear opening to allow it to burrow into sand easily. The earless lizards at White Sands vary greatly in color, often among populations only a few hundred meters apart: The further into the gypsum dune field you travel, the lighter the lizard are... making them harder to spot on the sand.
