Chuckwallas are isolated to mostly the northern and northwestern portions of the Navajo Nation. They live in rocky areas and are known to wedge themselves into tight rocky crevices when disturbed. They can really wedge themselves in by inflating their lungs to fill the crevice. Chuckwallas are mainly herbivorous and feed on leaves, fruit, flowers of annual and perennial plants.

Lizard is named "Na'ashó'iiłbáhí" in the Navajo language. The lizard is said to be respected, not to be killed or eaten. Also, one should not watch the lizard eat or mate.
