Mojave Rattlesnake
Crotalus scutulatusAlso known as Mojave Green, Mojave Pit Viper
Mojave rattlesnakes navigate arid scrublands and high desert valleys, relying on thermoreceptive facial pits to strike warm-blooded prey in complete darkness. Their venom is famously potent, containing a lethal cocktail of neurotoxins and hemotoxins that rapidly disables small mammals. Distinctive wide white rings on the tail preceding the rattle help field observers separate them from other desert pit vipers.

- Very high
- Why interaction risk is very high
- Highly venomous; maintain a distance of at least three meters and never corner or touch.
- Why it is dangerous
- Injects potent neurotoxic and hemotoxic venom that can cause systemic paralysis, muscle breakdown, and respiratory failure.
- How to recognize a risky encounter
- Recognized by broad white tail rings that are significantly wider than the dark rings just before the rattle.
- What to do
- Stop moving immediately upon hearing a rattle, locate the snake, and slowly step back at least three meters.
Responsible observation
