How to identify
This lizard is distinguished by the spiny scales on its legs and tail, unique banded pattern, and thick black collar outlined in white across its shoulders. Its sides and legs are light grey while its back has darker grey centralized bands with faded edges that get darker towards the tail and turn into solid black bands part way down the tail. It has a row of spiked scales that line the back of its head, and down each side of the neck. Males often have blue patches on the ventral sides of their belly. Can reach 12 inches in total length.
Range
The Chihuahuan Desert from central Texas through the panhandle, and into southern New Mexico and north central Mexico.
Habitat
These lizards are found in semi-arid rocky areas with lots of crevices for hiding.
Variations
Grey & black bands may have blue highlights. Their overall coloration may be shades of brown and tan, rather than black and grey.
Similar species
Similar to the crevice swift (*Sceloporus torquatus*) or blue spiny lizard (*Sceloporus cyanogenys*) which are often more colorful and lack distinct banding patterns. These species are not likely to overlap in range.
