Species Description

This small rattlesnake can be found in the "sky islands" of Arizona: isolated mountain ranges surrounded by desert. As such, they can be found between 5000-9000 ft elevation in canyons and forests. They primarily prey on lizards, mice, and centipedes.

Fun fact: The Arizona ridge-nosed rattlesnake is the state reptile of Arizona!
