Baird & Girard, 1852
The crevice spiny lizard (Sceloporus poinsettii) is a species of small, phrynosomatid lizard. The epithet, poinsettii, is in honor of American physician, botanist, and statesman, Joel Roberts Poinsett.
The crevice spiny lizard is typically grey in color, but sometimes can have a ruddy red-brown appearance with a black and white collar around the neck region. The underside is typically light grey, but males often have blue patches on either side of their bellies. The tail typically has black banding. Their scales have a distinctly spiny texture. They can grow to 11.8 cm (4.6 in) snout-to-vent length, and 31.1 cm (12.2 inches) total length.
Crevice spiny lizards are typically shy and nervous, fleeing up a rock face or into a crevice if approached. They prefer semi-arid habitats, often of limestone rock, where there are numerous holes and easily accessible cracks.
