Urosaurus auriculatus
Urosaurus auriculatus, also known as the Socorro Island tree lizard, is a species of lizard. It is endemic to Socorro Island, one of the Revillagigedo Islands off Baja California. Urosaurus auriculatus is found through much of the island; it is absent from areas of erosion caused by overgrazing by sheep.
Adult lizards measure on average in snout–vent length. The species is oviparous.
