Yarrow's Spiny Lizard

Description:

A medium-sized (up to 105 mm or 4.1" from snout to vent), lizard with large, pointed, keeled, overlapping scales and a broad, black collar. The rear edge of the collar is bordered by a thin, white line. Base coloration is gray or olive-gray. Upon emerging from shelter specimens may be very dark gray or black. The top of the head is plain dark gray or olive-gray. Each body scale is pale and edged in black giving the torso a net-like pattern.

Belly markings are faint or absent in females. The scales on the tail are larger and more spiny than those of the body. Males have blue patches on the belly and throat.
