Western Diamondbacks are a large grayish to brown rattlesnake. Their tail has alternating black and white rings or bands of equal length. Very distinctive diamond-shaped blotches on the back bordered by a lighter color usually white.

The Western diamondback is Arizona's largest rattlesnake. They can reach lengths of 3-4 feet and occasionally reach a length of 5 feet.

Diamondbacks are a generalist feeder. Neonates will prey on lizards and small rodents. As adults they will prey upon rabbits, hares, squirrels, roadrunners, quail, dove, thrashers, frogs and toads.
