A Blacktailed Rattlesnake hiding deep in a cave on an extremely hot day. During the heat of summer, rattlesnakes like this one may stay hidden away from lethal temperatures, staying in one spot or coming just outside the entrance after dark.
An Arizona Ridgenosed Rattlesnake in southeastern Arizona. These small rattlesnakes are common where they are found, but even ranchers born and raised in the area usually have no idea it exists. That’s thanks, in part, to its nearly perfect camouflage, making it about invisible in oak leaf litter and bunchgrass.
A Gila Monster peeking out of its spring staging spot, just down the hill from where it spent the winter. It shares this spot with several other Gila Monsters, a handful of Western Diamondback Rattlesnakes, and the occasional tortoise. It will spend the majority of each day during the early spring doing, basically, this. Resting in partial sun, disappearing if predators approach, and waiting to head out in nest-hunting mode as soon as the time is right.
The tiny face of a Sonoran Coralsnake. These tiny snakes are highly venomous, but reluctant to bite. Avoiding this is simple: don’t make the stupid decision to pick one up. If you can do that, there is no danger from these little snakes.
A Blacktailed Rattlesnake coiled in the grass in the Madrean woodlands of southeastern Arizona. These large, greenish rattlesnakes are a common sight for hikers and naturalists in the area.
A Sonoran Lyresnake found in central Arizona on a night hike.
The face of a Chihuahuan Hook-nosed Snake. These are small eaters of invertebrates. The subtle scoop on the end of the nose is helpful for finding prey in the sandy, grassland soil where they live.

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.
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.
Coachwhips are out and about on even the hottest days, rarely active at night. But they can still be found where they sleep, which is often up in trees high off the ground. We spotted this one doing just that just above eye level on a late night hike. These long, slender snakes are great climbers, and this is a reasonably safe spot for such an animal to evade predators and get off the hot ground.
