Species group: Swifts and Spiny Lizards
Scientific name: Sceloporus poinsettii
The Crevice Spiny Lizard (Sceloporus poinsettii) is a small, phrynosomadtid lizard which is native to the Chihuahuan desert, in US states of Texas and New Mexico, and in the Mexican states of Chihuahua and Coahuila. It prefers rocky arid and semi-arid environments. It is commonly seen on boulders, in canyons, and in rocky outcrops.
Appearance / health:
Crevice spiny lizards are typically grey in color, but sometimes can have a ruddy red-brown appearance with a black and white collar around the neck region. Their underside is typically light grey, but males often have blue patches on either side of the belly. Their tail typically has black banding. Their scales have a distinctly spiny texture. They can grow from 5-11 inches in length.
Like many other lizards, spiny lizards exhibit metachromatism, which involves color changes with changes in temperature. When it is cooler, colors are much darker than when the temperature is high. Darker colors increase the amount of heat absorbed from the sun and lighter colors reflect solar radiation.
Crevice Spiny Lizards are insectivorous, consuming a wide variety of spiders, beetles, and other insects, but they will sometimes also consume tender vegetation.

Look but Don't Touch
This attractive lizard and its relatives are also called “swifts” – and you need observe them only a short time (or try to catch an escapee!) to see how fitting that name is. Spiny lizards have much to recommend them, but they will thrive only in a large enclosure (a 55 gallon tank is ideal for a pair or trio) that offers plenty of rock and driftwood perches and hide-aways, hot basking temperatures (95-100 F), and access to high levels of UVB. Ever alert for predators and prey, they tend to remain high-strung in captivity, and are best thought of as pets to observe rather than handle. Captive-born individuals may respond well to handling, but unfortunately many in the trade are wild-caught. A varied diet comprised of roaches, crickets, hornworms, sow bugs, butter worms and wild-caught insects, along with vitamin/mineral supplements, is essential to their well-being; crickets and mealworms alone will not suffice..
