Distribution and Habitat
Located primarily in the southwestern region of the United States, the Sidewinder can be found in parts of eastern California, western Arizona, and southwestern Utah.
Sidewinders can be found residing in arid regions such as rocky hillsides as well as desert sand dunes.
Reaching upwards of 32 in. in length, Mojave desert sidewinders are typically pale in color to better help camouflage themselves. Additionally, this species contains horn-like scales above their eyelids, making identification an easy process.
There are 3 subspecies of Sidewinder. Mojave desert (cerastes), Sonoran desert (cercobombus), and Colorado desert (laterorepens).
Mojave desert sidewinder females are typically larger than males.
