A large Regal Ringnecked Snake greeted me in my driveway as I headed out for the night to look for snakes. Ironically, this was the species I was hoping to see when I set out. This one was about 20″ long, which is large for a ringneck, though not so much so in Arizona. I got some photos and let it go on its way.

A Blacktailed Rattlesnake from southeastern Arizona. They are large, common rattlesnakes in the mountainous regions of much of the state, where they are often misidentified over generations as Mojave Rattlesnakes due to a misunderstanding of the color green in rattlesnakes.

A Southwestern Speckled Rattlesnake making it difficult to tell where snake ends and rock begins.

An Arizona Black Rattlesnake resting in partial cover after an exceptionally rainy few days. In this area, along the eastern edge of their range in Arizona, the species can look a bit different. The light bands on this individual, for instance, are wide, in some cases as wide as the darker blotches they surround, and the snake may never darken (much). This is typical for the area, though, as most of the photos you may see of Arizona Black Rattlesnakes online or in field guides are from a handful of more central locations.

A good-sized Costa Rican Coralsnake we saw in the grass on a family vacation. These are very different than the coralsnakes we have back in Arizona. It’s much larger and willing to strike, which it did repeatedly. These snakes are a handful to get photos of, but we managed and let it disappear back into the forest.

A Southwestern Speckled Rattlesnake resting in the shade outside its summer aestivation den. It’s one of a handful that gather here each year to hide from the heat and gestate.

A young Mojave Rattlesnake at rest, lifted just off the surface of the warm sand to get a little air flow. Thermoregulation is far from just “sunning” – much of the activity of reptiles in the desert during the summer is about getting cooler, rather than warmer.

I was on a night hike in the Amazon and just about to step over this knee-high buttress when I noticed it was occupied. A young Fer De Lance (Bothrops atrox) was waiting on top, but I was not the rodent it was hoping to come along. The broken green and black shapes in its pattern would have made this easy to miss.

A relatively colorful Tiger Rattlesnake found in Santa Cruz County, Arizona awhile back. These rattlesnakes are common in the thornscrub hills along the Arizona/Mexico border.
