A Twin Spotted Rattlesnake that we found in eastern Arizona, showing off many more than “twin” spots. These tiny rattlesnakes can vary greatly in appearance from one location to the next, even between individuals in a single population. These are not likely to be seen unless you are spending time in the highest areas of […]

A mature Black-tailed Rattlesnake we found on a late-night hike near Phoenix. These snakes live in mountainous or hilly areas, where they are often confused with a number of other rattlesnake species.

One of a handful of Bamboo Vipers (Craspedocephalus gramineus) we found on a night hike in the hills of southern India.

Close up with a Trans-Pecos Ratsnake (Bogertophis subocularis). I found this one in South Texas, though they also range through much of New Mexico, and into Mexico.

A pretty little Arizona Ridgenosed Rattlesnake from a humid week in southeastern Arizona.

This tiny whipsnake (Chironius sp.) we saw in Peru is basically a long life support system for eyes. It’s likely less cute to the many lizards and frogs in the region.

I found a Rosy Boa that had apparently lost its tail somewhere along the way. This is one of two species of boa native to Arizona, found in rocky areas in the west-southwestern third or so of the state.

A Grand Canyon Rattlesnake we found near its namesake a while back. This is what many refer to as the “Grand Canyon Pink”, though they are often, or usually, not pink, but this straw color or similar. The pattern here is strong, as is often typical in males and younger snakes, but may fade with […]

A Nose-horned Viper (Vipera ammodytes) from Greece a few years ago.
