Desert Iguanas are found in the Mojave & Sonoran Deserts of the U.S. southwestern region. Their main habitats in their range are creosote bush scrubs. Desert Iguanas tend to find shelter from predators in shade of creosote bushes and in rodent burrows at the base of the scrubs. They will also into cracks and holes in boulders for cover.

Males and females generally have little sexual dimorphism (they look the same), except with the males having a larger head and femoral pores. During breeding season, both sexes develop pinkish coloration on their sides. Lifespan can last up to 10 years. Adults are around 5.5 inches snout to vent (SVL). Desert Iguanas are generally considered one of the most heat tolerant North American lizards.

Like Chuckwallas, Desert Iguanas are generally herbivorous lizards but will also take insect prey. Plant parts such as leaves, buds and flowers are generally consumed. Creosote bush make up a major component of their diet. In turn, Coachwhips, Sidewinders and California Kingsnakes feed on Desert Iguanas. Hatching desert iguanas are also subject to predation by Long-nosed Leopard Lizards.
