About Crotaphytus vestigium Smith & Tanner, 1972
Crotaphytus vestigium, commonly called the Baja California collared lizard, is a large-bodied lizard species. It has a broad head, short snout, granular scales, and two distinct black collar markings. These collar markings are separated at the dorsal midline by more than 12 pale scales. Its base body color ranges from tan to olive, and it has broad dark crossbands across its body. Adult snout–vent length falls between 6.9 and 11.2 cm (2.7 and 4.4 in). Juvenile Baja California collared lizards have a similar appearance to adults, but their banding is more distinct. Males of this species have enlarged postanal scales, a blue-grey throat, and large dark blotches on their flanks. This species is uncommon, and it prefers rocky habitats, particularly washes.
