Clark's Spiny Lizard (Sceloporus clarkii)
Description: These are medium to large lizards with snout-vent lengths ranging from 2 1/4 to 5 1/4 inches. These robust lizards have keeled, pointed scales. Background color is usually subdued gray, tan, or blue with a striking wide, purple stripe down the back and single yellow scales scattered on the sides (S. magister), or scattered turquoise scales mixed with tan and brown on the back and sides (S. clarkii). Both species have a dark collar under or around the neck; males have vivid blue throats and under-bellies. Females develop orange to red heads during the breeding season. The presence of distinct cross bands on the forlimbs is a usefull feature for distinguishing the species from Desert Spiny Lizard Sceloporus magister, a vaguely similar animal that is quite abundanrt in the region.
Habitat: This lizard occurs primarily in wooded habitats of lower mountain: oak-pine woodland, tropical deciduous forest, subtropical thornforest, riparian woodland communities that penetrate into more arid landscapes from forested mountains; it also inhabits rocky areas at the lower edges of foothills and in oak-grassland communities as low as 1,060 meters. It is primarily a tree-dweller (climbs high into trees) but also can be found on the ground among rocks. Woodrat nests in trees may be used as refuges.
Range: The range encompasses central and southeastern Arizona (and disjunctly southwestern and northwestern Arizona) and southwestern New Mexico and extends southward to northern Jalisco, Mexico, including Islas Tiburon and San Pedro Nolasco in the Gulf of California. Elevational range extends from sea level to about 6,060 feet

Reproduction: Central Arizona: eggs laid June to mid-July; most females produce 1 clutch annually, some lay second clutch in July; clutch size averages 20; females sexually mature in 22 months
Status: Listed as Least Concern in view of the relatively large and stable extent of occurrence, area of occupancy, number of subpopulations, and population size. No major threats have been identified.
