Species Description

This southwestern rattlesnake species can get very large at up to about 7 feet long, though generally they are much smaller. They are generalist feeders and are important predators for rabbits, gophers, and other medium-sized mammals. They are easily distinguished from many other rattlesnake species by their stark black-and-white tail before their rattle.

Fun Fact: The western diamondback rattlesnake occupies a diverse range of habitats from sea level to 7000 feet elevation.
