Description
Size
Up to 5 inches (126 mm) SVL.
Appearance
A large lizard with a big triangular head, wider than the neck, which contains folds on the sides. The nose is elongated slightly.
Color is dark gray to light or dark brown, overlaid with large paired dark spots separated by cream colored bars. The dark spots connect on the tail to become dark crossbands separated by cream bars. The ground color lightens considerably as the lizard's body temperature increases. Females develop red or orange coloring when gravid.
Behavior
Diurnal, emerging in the morning to bask. Sometimes found basking on rocks and road berms. Instead of running away, sometimes flattens the body to rely on cryptic coloring to hide from a predator.
Diet
Eats lizards and arthropods, which are caught by ambush, or sitting and waiting for the prey to pass by closely.
Reproduction
Breeds from April to July. Eggs are probably laid in the Summer.
Range
In California, ccurs only in the extreme southwest part of the state around Cameron Corners, Campo, and the Potrero Grade. Ranges south throughout much of Baja California.
Habitat
In California, inhabits coastal sage scrub, chaparral, and oak woodland. Prefers flat areas with open space for running, avoiding densely vegetated areas.
