Western Diamondback Rattlesnake
Crotalus atrox

Size:  6 - 7 ft
Southwestern 1/4 to central and east central Oklahoma.  The western diamondback rattlesnake, the infamous snake from the westerns, likes a more desert-like environment, landscaped with cactus, yucca, and tumbleweeds.  Although it is not the most venomous snake in the state, this is without a doubt the most dangerous snake in Oklahoma.  A high strung and hot-tempered snake, the western diamondback will stand in defense and strike with little provocation.  This snake is responsible for most annual snakebites, but few are actually fatal.  It must be taken into consideration that the incidence of snakebite in Oklahoma increases during the annual rattlesnake roundups held in five locations each spring.
