Common Chuckwalla
Sauromalus ater
(Sauromalus obesus)
Photo by Mike Plagens on Mother's Day 2006 at North Mountain, Phoenix, Arizona, USA. It is hosted at the Wikimedia Project. Notice that there is a small dipteran (fly) alighted on the back of the lizard. If you want to see a larger image and hazard a guess as to the fly's purpose and identiy, Click Here.
This specimen was found crawling on a stuccoed wall near Carefree, Arizona.
This large lizard is a vegetarian and rarely ventures far from rock crevices where it can wedge itself in to escape predators. In the Sonoran Desert the best place to see them is in low rocky mountains where there are plenty of boulders and crevices. The best time is mornings during the spring when they climb out upon the boulders to sit in the sun. They are common at South Mountain Park in Phoenix, Arizona.
