DISTRIBUTION, ABUNDANCE, AND MSEASONALITY
The western whiptail is widely distributed but uncommon over much of its range in
California, except in desert regions where it is abundant in suitable habitats. The species
is found throughout the state except in the humid northwest, along the humid outer Coast
Ranges, or mountainous regions above 2290 m (7500 ft). Also absent from much of the
northern part of the Central Valley (Montanucci 1968). The western whiptail occurs
in a variety of habitats including valley-foothill hardwood, valley-foothill hardwood-conifer,
valley-foothill riparian, mixed conifer,
chamise-redshank chaparral, mixed
and annual grassland.

Cnemidophorus tigris multiscutatus - USGS Western Ecological Research Station, San Diego Ca.
Size: 2.4-4.6 in (6.0-11.7 cm)
Distinguishing characters: A species with eight light-colored stripes that are often very indistinct, with crossbars in adults suggesting checkered appearance; dark markings on dorsum with yellow, tan or brown background; throat pale with black spots; long tail; enlarged, square scales on venter; dorsal scales fine and granular; tongue is forked and flicked continually.
Juveniles: Similar to adults, with distal portion of tail bright blue-green; in Orange and Riverside Counties they are striped.
Dimorphism: Enlarged femoral pores in males.
Similar species: Cnemidophorus hyperythrus: Striping more distinct; does not appear checkered or spotted; legs and tail cobalt blue in juveniles.
Additional notes: A distinctive species with a jerking gait, rarely sits still. Adults are surprisingly strong when handled and have very sharp claws.
