Arizona Ridge-Nosed Rattlesnake (Crotalus willardi willardi)
Description: Color patterns are generally a dark/brown base with pale or white horizontal striping. It rarely weighs more than 3-4 ounces as an adult or exceeds 24 inches in length. Its upturned nose scales give this species its common name. It has bold, white stripes on its brown face causing some people to speculate that the Chiricahua Apaches modeled their war paint after this snake's facial markings.

Range: This small rattlesnake can be found in the "sky islands" of Arizona and Sonora: isolated mountain ranges surrounded by desert.

AZ
Venom: This snake's venom does not appear to be particularly potent and no human deaths from its bite are on record.
Diet: Arizona ridge-nosed rattlesnakes are a generalist predator which preys on lizards, mice, and centipedes.
