The Mojave rattlesnake is a venomous snake found primarily in the southwestern United States and parts of Mexico. It is known for its distinctive coloration, which can range from light brown to greenish, often with darker blotches. This snake typically grows to about 3 to 4 feet in length and is recognized by the rattle at the end of its tail, which it uses as a warning signal when threatened. Mojave rattlesnakes inhabit desert regions, rocky hillsides, and scrublands. They are primarily nocturnal, hunting small mammals, birds, and lizards. Their venom is considered one of the most potent among rattlesnakes, making them a significant concern for humans and pets in their range.
