Banded Rock Rattlesnake from southeastern Arizona. These snakes, typically the males, can have a metallic blue-green shine along the back and outline of black bands, often against other bright pinks, blues, and orange. It matches the lichen covering rocks where they live. This one is a good example of a mature male of the species […]

To another small snake, this is a terrifying sight. A venomous snake-eating specialist that will take prey almost as large as it is by clamping down tight and flipping over, using its atypically long body as an anchor. After releasing, it follows the mortally wounded snake, face to face, watching it until it either dies […]

Can you tell the age of a rattlesnake from counting the segments of its rattle? For the most part: no. But sometimes, it’s easy. This young Western Diamondback Rattlesnake was found late in the monsoon season. From its rattle, it can be seen it’s shed its skin exactly two times – once to reveal the […]

Sonoran Sidewinders can be incredibly common in the right habitat, but that doesn’t often put them in the path of homeowners in the Phoenix and Tucson areas. Of the six species of rattlesnakes that can be found at the native habitat contact zones, this species is the first to disappear whenever roads come in. They […]

A pair of Arizona Black Rattlesnakes take the prime spot at the den, with a half dozen or more shuffling throughout the day behind them. For these snakes, it’s early den egress time, when they stage at and near the den for awhile before heading out for the season. This den is shared by two […]

One of the many Zebra-tailed lizards running around a popular beach in Cabo San Lucas, Mexico. Unlike about every other situation where we were wading through beach dune sands looking for lizards and snakes, this spot had a guy with a cooler selling ice-cold cervesas. This needs to be normalized in herpetology.

A large canebrake rattlesnake (timber rattlesnake) from forests of the southeast. This would not be a fun environment to live in if you were a squirrel.

A thin Western Diamondback Rattlesnake stopped for a moment while crossing a dirt road. Often, this behavior is misinterpreted as “sunning”. While snakes may stop to bask like this, in many cases, it’s just that the snake saw the observer first and stopped moving in hopes the perceived predator will not notice it. They don’t […]

Southwestern Speckled Rattlesnake on the move late at night in Phoenix. These snakes are the most commonly encountered snake on many trails in the area. For the reasons you can see here, and others, these snakes are quite often misidentified as Tiger Rattlesnakes when people see them. At popular trails like Piestewa (not where this […]

Sonoran Lyresnake from the southwestern corner of Arizona. These snakes are common in the right habitat, but most lifelong Arizona residents will never see one.
