Largest Lizard Species in Arizona
The largest lizard in Arizona is the desert iguana, a robust reptile adapted to arid environments. Adults can reach up to 16 inches in total length, including the tail, making it the most substantial lizard species regularly found in the state.
Habitat and Range
Desert iguanas inhabit the Sonoran and Mojave deserts, favoring rocky foothills, scrublands, and sandy washes. They are commonly observed in southern Arizona, where warm temperatures and sparse vegetation match their ecological needs.
Behavior and Diet
This lizard feeds primarily on plant material, including leaves, flowers, and fruit. It is diurnal, often seen basking on rocks or sprinting across sandy ground when disturbed.
Conservation and Observation
Desert iguanas are not currently listed as threatened in Arizona, though habitat loss and human activity can affect local populations. For more details on Arizona reptiles, visit the Arizona Game and Fish Department website at https://www.azgfd.com/wildlife-reptiles.
