The Crotalus atrox or Western diamondback rattlesnake is a heavy bodied snake with a triangular shaped head.

There are two dark diagonal lines on each side of its face running from the eyes to its jaws. It has dark diamond-shaped patterns along is back. The tail has black and white bands just above the rattles.

Crotalus atrox are pit vipers. This means that they have a heat sensing pit (loreal pit) located behind each nostril that can detect differences in temperature, sometimes differences that are only a fraction of a degree apart.

The heat given off by an animal is detected by the snake helping it to determine predator from prey.

This snake is considered a generalist, which means that it isn’t too picky about its habitat. It can be found living in deserts, grassy plains, forests, rocky hillsides and areas along the coast. It lives in elevations from below sea level up to 6500 feet.

The Crotalus atrox ranges throughout the southwestern United States (Arizona, California, New Mexico, Oklahoma and Texas)and northern half of Mexico.

Currently, the Crotalus atrox or Western diamondback rattlesnakes are not threatened or endangered.

A rattlesnake can move its rattle back and forth 60 or more times per second.
