A Mojave Rattlesnake on the crawl after a wet night in southeastern Arizona. It’s moving laterally, hissing and watching the perceived predator with the camera, but not rattling. As this species often does, instead, it curls its tail and “wags” it slowly as a display. Prairie Rattlesnakes, notably, will often do this tail-curling behavior instead of rattling.<\/p>\n\n\n\n

This guided retreat, where the snake moves laterally to cover while keeping the business end pointed forward, causes a lot of confusion with observers. For one, it’s not always a straight line away, but to cover. That cover can be a vehicle, bushes, or a cast shadow … including from the person watching it. This, and confirmation bias from decades of beloved folklore, contribute to the many tall tales about Mojave Rattlesnakes.<\/p>\n\n\n\n
