Over 20 different species of rattlesnakes are recognized in the United States.  Some seldom reach a length of 2 feet and a few reach over 7 feet.  All possess a rattle at the end of the tail.  A facial pit is located between the eye and nostril.  Crotalus have small scales on top of the head and Sistrurus, the Pigmy Rattlesnakes, possess large scales on top of the head.  The eyes are small, the pupils are elliptical.
All bites from rattlesnakes are dangerous, the Mojave Rattlesnake appears to have the most toxic venom among the rattlesnakes in the United States.
