The Mojave rattlesnake has a reputation for being dangerous and aggressive, but like many myths, the truth is far from it, and much more interesting.
Native to California and other southwestern States and Mexico, the Mojave rattlesnake (Crotalus scutulatus) behaves just like any other snake. They try to avoid conflict, use their camouflage, and defend themselves when they feel threatened. They are found in dry habitats like deserts, grasslands, and areas with scrub brush and cacti. Unlike the stories that paint these snakes to be villains of the desert, they are shy and solitary animals that work hard to survive in a harsh environment.
The Mojave rattlesnake plays an important role in their ecosystem and they even help humans by controlling rodent populations. This important predator helps keep food webs stable. These rattlesnakes are ambush predators and use their highly potent venom to subdue their prey. Their venom composition is interesting, because some populations of Mojave rattlesnakes have can have higher neurotoxic properties compared to other rattlesnake species. While most snakebites are accidents, sometimes bites do happen, which can result in a life threatening emergency. However, mortality from a Mojave rattlesnake bite is very rare thanks to modern medical care and great quality antivenom. People can learn to safely coexist with rattlesnakes by being aware of their surroundings while in rattlesnake habitat and managing their property to reduce snake encounters.
Mojave rattlesnakes are notorious for having a bad attitude, but this is really their self-defense. They may rattle or move with more enthusiasm than other types of rattlesnakes, but this is a defensive behavior that comes out when being attacked first. Like all rattlesnakes, they signal their presence with a rattle and give us plenty of warning. Combined with this perceived aggressive behavior and highly potent venom, there are many legends about this spectacular serpent. When left alone, they keep calm and quiet. Observing them from a distance can unveil their true nature and beautiful pattern. They are deserving of curiosity, not fear.
