Species of lizard

Sceloporus magister, also known as the desert spiny lizard, is a lizard species of the family Phrynosomatidae, native to the Chihuahuan Desert and Sonoran Desert of North America.

In the United States it is found in the states of Arizona, California, Texas, New Mexico, Nevada, and Utah. It is also found in the Mexican states of Sonora, Baja California, Chihuahua, Coahuila, and Durango.

An adult male desert spiny lizard usually have conspicuous blue/violet patches on the belly and throat, and a green/blue color on their tails and sides. Females and juveniles have large combined dark spots on their back and belly areas, and the blue/violet and green/blue coloring is absent. Both sexes have brownish/yellow triangular spots on their shoulders. A female desert spiny lizard will lay anywhere from 4 to 24 eggs during the summertime.

The desert spiny lizard ranges across the deserts of southwestern Arizona and the northeastern plateaus at elevations ranging from near sea level along the Colorado River to about 5,000 feet.

Like many desert lizards, desert spiny lizards adjust their internal temperature by changing color so they are darker during cool times, which allows them to absorb more heat from the sun, and become lighter during warm times so they reflect more solar radiation. The desert spiny lizard also uses camouflage so it is not so easily seen by predators. Usually, during the morning hours, it will be out basking in the sun on rocks or any hard surface that is in direct sunlight, but like many desert reptiles, it will seek shelter, usually underground in burrows or any suitable cover that provides shade, during the hottest part of the day in the summertime, as shade provides cooler temperatures than on the ground's surface. It hibernates in late fall and during the cold months of winter before re emerging in spring.

Biotic communities including Sonoran Desertscrub, Great Basin Desertscrub, Semidesert Grassland, Interior Chaparral, and woodlands are home to this lizard. It is usually encountered on lower slopes, bajadas, plains, and low valleys, often in the branches of trees or in the vicinity of ground cover such as wood piles, rock piles, and pack rat nests. The desert spiny lizard is a primarily arboreal species that prefer cottonwood, yucca, Joshua trees, and ironwood.

The desert spiny lizard feeds on a variety of insects including ants, beetles, and caterpillars. It also feeds on spiders, centipedes, and small lizards.
