The Coachella Valley fringe-toed lizard (Uma inornata) depends on windblown sand dunes and hummocks. A specialized sand dweller colored like the sand it lives on, this lizard is threatened by ORVs, agriculture, urban sprawl, loss of sand sources, exotic plant invasions, and utility projects. Uma's fringed toes allow it to speed over and under the sand. Every orifice of this lizard is protected to keep out sand when the lizard is under the surface. This species typically remains under the surface from November-February.
