A Cabrara’s Slender-legged Treefrog (Osteocephalu cabrerai) from Peru a couple of years ago. These are large treefrogs that often have these rough areas that can make them about invisible in the chaotic backdrop of the Amazon.

A Gila Monster (Heloderma suspectum) basking on a cool Spring day. Usually, it may seem that the bright yellow and black pattern of these animals makes them hard to see … but this shows where it works. The high-contrast, chaotic pattern makes the shape of a lizard disappear in dappled light. It’s common for even […]

A Tiger Rattlesnake from the Phoenix area. The blue-grey base color fading to pink with dark grey bands is a standard look in the area. These snakes are common in popular hiking areas, yet most people who frequent them for a lifetime will never see one because of their cryptic nature.

A Southwestern Speckled Rattlesnake found in ambush at sunup on a hot day in Arizona. Nearby, a cave with several more has been used as an aestivation site to avoid death in the summer months. This photograph was taken in 2014. In recent years, the site has been abandoned, most likely due to increased human […]

A Grand Canyon Rattlesnake in the last light of the day in northern Arizona.

Up close with a Banded Rock Rattlesnake from the sky islands of southeastern Arizona. These small, mountain-dwelling rattlesnakes are quick to flee when found. A typical encounter for a hiker is a short buzz and a glimpse of the last half of its body sliding under a rock. The tiny black flecks you see in […]

A young Sonoran Sidewinder (Crotalus cerastes cercobombus) with a nice, clean pattern near Phoenix last year. These small rattlesnakes are very common in the right habitat, but rarely seen by hikers because of the nature of that same habitat.

This little American Alligator didn’t care much about my presence as it spent the morning lounging. Most, upon any kind of approach, slip silently away. Growing up in the West, I rarely miss an opportunity to take a picture of one when I can.

I saw this Mojave Rattlesnake (Crotalus scutulatus) crossing a dirt road near the U.S./Mexican border a few years ago in mid-elevation semi-desert grassland. Several other species can be found in the same band o transitional habitat, including Arizona Ridgenosed Rattlesnakes, Banded Rock Rattlesnakes, Western Diamondback Rattlesnakes, and Blacktailed Rattlesnakes. I escorted it off the road […]

A large Veracruz Neotropical Rattlesnake (Crotalus mictlantecuhtli) from a trip to Mexico a few years ago. This species was recently recognized as a separate lineage of the Neotropical Rattlesnakes, described in 2020, about a year before this photograph was taken.
