What is a Desert Iguana
The desert iguana, also known as the Crested Lizard, (Dipsosaurus dorsalis) is one of the most common lizards of the Sonoran and Mojave deserts of the southwestern United States and northwestern Mexico.
They also occur on several Gulf of California islands.

Size and Body Description
A blunt head and a long tail, the desert iguana is a medium-sized lizard that grows to 24″ including the tail.
They are pale gray-tan to cream in color with a light brown reticulated pattern on their backs and sides.
Down the center of the back is a row of slightly-enlarged, keeled dorsal scales that become slightly larger as you move down the back.
The reticulated pattern gives way to brown spots near the back legs, turning into stripes along the tail.
The tail is usually around 1½ times longer than the body from snout to vent.
Desert iguanas are primarily herbivorous, eating buds, fruits, insects, and young leaves of many annual and perennial plants.
They are especially attracted to the yellow flowers of the creosote bush.
Habitat and Range

What is a Desert Iguana
I am an outdoor enthusiast who would rather be on a backcountry backpacking trip than a stroll on the beach (although I do love the beach!).
Living in Las Vegas has afforded me the opportunity to easily explore the Southwest region of the United States.
A nature lover, I am often found at the end of the pack taking photos and videos of the wildlife found on the trails. Colorful flowers, desert animals, and unusual geological rock formations are often the majority of my photos.
