One of the most common lizards in desert regions, you are most likely to find them in inland Orange County where conditions are more favorable for them. They can reach up to about 5 inches in length and vary in color. Males and females both have various color morphs they use during breeding season which determines their behavior. Certain color males are more territorial, lay more eggs, have more females, or move around between females while certain color females lay more eggs or larger eggs. Everything about this is not entirely known. Males that are blue in color are more likely to approach humans.
