Wikipedia Abstract

Crotalus scutulatus (common names: Mojave rattlesnake, Mojave green,) is a highly venomous pit viper species found in the deserts of the southwestern United States and central Mexico. It is perhaps best known for its potent neurotoxic-hemotoxic venom, which is considered the world's most potent rattlesnake venom. Two subspecies are recognized, including the nominate subspecies described here.
