Baja California Rock Lizard

Petrosaurus thalassinus

Also known as Baja Blue Rock Lizard, Blue Rock Lizard, San Lucan Rock Lizard

Baja California rock lizards are striking, flattened reptiles renowned for their vivid turquoise body coloration, bright orange throat, and dark shoulder bands. They excel at navigating steep granitic outcroppings and massive boulder piles across the southern Baja California peninsula. When alarmed, they wedge their flattened bodies tightly into narrow rock crevices, expanding their torsos with air to resist extraction.
