The Western Diamondback Rattlesnake, Texas diamond-back or Crotalus atrox is a venomous rattlesnake species found in the southwestern United States and Mexico. It is likely responsible for the majority of snakebite fatalities in northern Mexico and the greatest number of snakebites in the U.S.

The Western diamondback rattlesnake or Crotalus atrox lives in elevations from below sea level up to 6,500 feet. This species ranges throughout the southwestern United States (Arizona, California, Colorado, New Mexico, Oklahoma and Texas) and northern half of Mexico. Currently, western diamondback rattlesnakes are not threatened or endangered.

The Western diamondback rattlesnake or Crotalus atrox adults commonly grow to 4 ft. in length. Males become much larger than females, although this difference in size does not occur until after they have reached sexual maturity.

The Western diamondback rattlesnake or Crotalus atrox is probably the second largest-bodied species of rattlesnake, behind only its close cousin the eastern diamondback rattlesnake, and is also the second largest of North American venomous snakes.

The color pattern generally consists of a dusty-looking gray-brown ground color, but it may also be pinkish-brown, brick red, yellowish, pinkish, or chalky white. This ground color is overlaid dorsally with a series of 23-45 (mean, 36) dorsal body blotches that are dark gray-brown to brown in color.

The first of these may be a pair of short stripes that extend backwards to eventually merge. Some of the first few blotches may be somewhat rectangular, but then become more hexagonal and eventually take on a distinctive diamond shape, hence the name “diamondback rattlesnake”. The tail has two to eight (usually four to six) black bands separated by ash white or pale gray interspaces.

The Western diamondback rattlesnake or Crotalus atrox prey included prairie dogs, kangaroo rats, pocket gophers, voles, woodrats, pocket mice, white-footed mice, Old World rats and mice, harvest mice, fox squirrels, cotton rats, ground squirrels, rabbits, jackrabbits, moles, and birds.
