San Clemente, Santa Barbara and San Nicolas. This lizard seems to be a food generalist and opportunist, taking advantage of whatever food source is available in an environment with few, if any, competitors. This species, like other members of this family, makes extensive use of cover. It is seldom observed on the surface in the open, but usually under objects or moving through thick vegetation, or around cover. Adequate cover in the form of vegetation, rock rubble, logs or other objects is probably the most important habitat requirement.
Nothing is known concerning the habitat requirements for reproduction.
It is obvious that some sort of secure cover is required during the birthing process, which may take up to several hours. Nothing is known concerning water requirements. Water in the form of dew and fog-drip is often present on the islands and captives are known to drink, but there are few sources of permanent water available. This species is secretive, extensively utilizing cover both when active and inactive. It occurs in a wide variety of habitats and seems to be limited only by available cover.
