Sceloporus merriami, commonly known as the canyon lizard, is a species of lizard in the familyPhrynosomatidae. The species is native to the south-western United States and northern Mexico.[1][2]
Adults of S. merriami may reach 58 mm (2.2 in) snout-to-vent length (SVL). Including the tail, they may reach 162 mm (6.4 in) in total length. The dorsal scales are small, and the lateral scales are granular.[5]
Dorsally, the canyon lizard is gray, tan, or reddish-brown, matching the rocks on which it lives. There are four rows of dark spots on the back, and a vertical black line in front of the front leg. Males have blue and black lines on the throat.[6]
