This is a large Common Krait (Bungarus caeruleus) that we found in the Western Ghats of India a few years ago. The photo isn’t great, but we weren’t taking any chances with this animal.

Southwestern Speckled Rattlesnakes (Crotalus pyrrhus) are some of the most cryptic snakes in the country. This white one isn’t an albino, but is showing off its natural color against the white granite in the environment where it lives.

A bright orange and pink Southwestern Speckled Rattlesnake we found in Yavapai County, Arizona several years ago, photographed in the last light of the day. These snakes look just like the rock they’re found near, so the iron-rich boulders where this one is from make for a very pretty animal.

A young Grand Canyon Rattlesnake I found near its namesake a little over a decade ago. As this snake matures, the clean pattern of its head and body will fade and degrade to a series of dark splotches and smudges against a simple background.

Sonoran Collared Lizards (Crotaphytus nebrius) are generally less brilliantly colored than their bright green relatives north of the Gila River. They can be standing tall on top of rocks on hillsides and outcrops, even in the heat of an Arizona summer day. When they are startled (which can happen from a disappointingly long distance) they […]

We saw this Western Diamondback Rattlesnake resting high on a ledge, just below a crevice where at least one other was resting.

A Blunt-headed Tree Snake from Guatemala a few years back. These are extremely thin snakes that can be very difficult to photograph, as they just never stop moving. This one took awhile, but eventually let me get this subpar shot.

Arizona Ridgnosed Rattlesnakes are common in a few mountain ranges in southeastern Arizona, but not found in the desert environments where most people live. They are usually seen by hikers and wildlife observers in the daytime, but often found moving at night as well.

A cool little viper with horn-like scales above the eyes. That’s a common thing with arboreal vipers in Central and South America, but vipers with “horns” are relatively few in comparison. They’re closely related to other montane vipers in the area that have similar structures, but live more familiar lives in steep, heavily vegetated forests. […]

A Greater Green Snake (Ptyas major) we saw in Hong Kong several years ago.
