Baja California Collared Lizard
Crotaphytus is from the Greek krotaphos, meaning the side of the head or temple region, and phyton, a creature or animal. It refers to the large jaw musculature of these carnivorous lizards. Vestigium, from the Latin, meaning a trace, refers to their reduced collars. In Spanish, the Baja California Collared Lizard is called escorpión, a general name for most lizards. An older scientific name for this species was Crotalus insularis vestigium.

The color of Collared or Crevice Lizards can vary from tan and brown to brilliant greens and blues. Their needs vary by place of origin.
Collared lizards are capable of running swiftly on their hind legs, the body held off the ground at a 45° angle, with tail and forelimbs raised. The stride is up to 3 times the length of the body. They do not lose their tails easily, as they are useful in maintaining balance as the lizards sprint on hind legs.
2.5 - 4 3/8 inches long (8.6 - 11.2 cm) excluding tail. The tail is often twice the length of the body.
A large lizard with a broad-head, a narrow-neck with a pair of black bands, large rear legs, and a long thick tail. Often described as looking like a small "dinosaur".
Color above is brown to olive with many small white spots and dashes and brown or reddish-orange crossbands. These crossbands are more pronounced on males. Females are not as brightly-colored as males, except when breeding when they develop reddish-orange bars and spots on the neck and body.
Mojave Black-collared Lizards are large headed, big bodied lizards with two distinct black collars separated by a white band. The dorsal coloration can range from a light tan to gray or reddish-brown, and is marked by fuzzy crossbands that are a lighter shade of tan or brown. There are usually light spots or speckles on the dorsal ground color.

Collared Lizards of the genus Crotaphytus are among the most colorful lizards in North America. Captive bred collareds make excellent captives as long as their basic requirements are met. I work with several species of collareds and welcome any information on collareds in captivity or in the wild. This site will be updated often with new pictures and information. Hope you enjoy.
AGGRESSION IN FEMALE COLLARED LIZARDS
C. L. Sloan and T. A. Baird [1999, Herpetologica 55(4):516-522] tested the hypotheses that intrasexual female aggression increases following oviposition, and that heightened post-ovipositional aggression functions in the defense of nesting sites in female collared lizards, Crotaphytus collaris. Daily focal observations on seven females prior to and after oviposition revealed that both agonistic intrasexual aggression and travel rates were higher during the five days following oviposition than during the five days before eggs were laid.
