The Mojave green rattlesnake is a poisonous pit viper native to the Southwest region of the United States and northern Mexico. It is potentially one of the most venomous species in North America, though most bite victims recover as long as they seek treatment immediately.
The snake is also known as the Mohave rattlesnake, which is pronounced the same as Mojave. It is commonly called the Mojave green rattlesnake because some specimens have a vibrant green coloration. The snake's coloration can range from brown to olive to green. Its species is identified as Crotalus scutulatus, with two main subtypes commonly identified: C. s. salvini and C. s. scutulatus.
