San Esteban Chuckwalla

Sauromalus varius


The San Esteban chuckwalla is the largest species of chuckwalla reaching 61 centimetres (24 in) in body length, 76 centimetres (30 in) overall length and weighing up to 1.4 kilograms (3.1 lb). It is considered a textbook example of island gigantism as it is 3 to 4 times the size of its mainland counterparts. Their skin is gray with tan to yellow patches over their entire bodies, and their faces are gray to black. Females are duller in appearance with less patches. Their colorations provide almost perfect camouflage against some of their predators.


These lizards live at Tulsa Zoo, Tulsa, OK, USA.
