A Southwestern Speckled Rattlesnake making its way up a nearly vertical wall, taking advantage of numerous leverage opportunities. Rattlesnakes can climb, but not with the same skill as some non-venomous snakes, like gophersnakes or kingsnakes. Even from a moderate height, a fall can injure or even kill the animal, so caution is needed.

A new mother Banded Rock Rattlesnake oversees her newborn babies at a rock pile in southeastern Arizona. This was during the monsoon season, when abundant moisture triggers the live birth of rattlesnakes. This mother stayed with the newborns until just after their first shed skin, at which point they all dispersed to surrounding habitat.

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 handful of the Chiricahua, Huachuca, Pinaleño, or Santa Rita mountain ranges.

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.
