The Baja California Lyre snake has a laterally flattened body and broad head on a slender neck. It has a V-shaped marking on top of the head resembling a lyre. It is light brown or grey above, with brown blotches. The blotches are roughly hexagonal and bisected with a pale crossbar. The underside is cream or white with pale brown spots. It has large, protruding eyes with vertical pupils. Juveniles are similar to adults in pattern, but have more contrasting color. Hatchlings are often black and white. The female is larger than male with extremely constricted tail. It is nocturnal and secretive terrestrial snake, and a good climber. It can be found during the day inside crevices in large rock outcrops, as well as crossing desert roads at night.
