Chuckwallas are experts at evading predators and danger. They possess a unique advantage by inflating their lungs to wedge themselves even tighter within the rocky crevices in their habitat. Their neutral colored-scales also aid in their camouflage from predators.
This lizard is an herbivore and its primary nutrients come from annual and perennial plant material. It also eats some insects found on the vegetation it consumes, and will use the plant material to obtain water as well.
The Chuckwalla is diurnal and primarily solitary. It remains close to its shelter when not out basking or eating foliage.
