Graphic Spiny Lizard
Sceloporus grammicusAlso known as Mesquite Lizard
Graphic spiny lizards spend much of their day basking on tree trunks, rock faces, and wooden fence posts, blending seamlessly against textured bark with their mottled grey-and-black patterns. Unlike many lowland relatives that lay eggs, this high-elevation specialist gives birth to live young, an adaptation protecting embryos from freezing montane temperatures. When approached by a perceived threat, individuals quickly scurry to the opposite side of a tree trunk to remain hidden.

Responsible observation
- Approach Quietly: Walk softly around tree trunks to prevent them from spiraling out of view.
