A Grand Canyon Rattlesnake from northern Arizona. In time, the pattern on this snake may continue to degrade and fade, but not to the same degree as is common for females of the species.

Ghost Anole
This Ghost Anole was one of many anoles seen on a trip to the high forests of Guatemala.
Sonoran Desert Tortoise in the Big Horn Mountains
A Sonoran Desert Tortoise resting in the shade in on a hot morning in the Big Horn Mountains of western Arizona. These tortoises become nocturnal during the hottest parts of summer, moving and eating after dark and returning to their deep caves by the time the sun hits the area again.
Speckled Rattlesnake In A Cave
A Southwestern Speckled Rattlesnake hiding from the sun near the entrance of a shallow cave in south Phoenix. During the springtime, this species can be found even relatively far from its rocky habitat, hunting birds and lizards at the base of creosote. This caliche cave, which is also the occasional home to a Sonoran Desert Tortoise or two, is about as far from its winter and summer preferred homes as it will get in the year, nearly a quarter mile from the nearest sizable rock.
Mojave Rattlesnake In Defensive Stance
This animal is not being aggressive, not seeking a fight, or coming after anyone. It’s a defensive Mojave Rattlesnake letting me know that coming closer would be a bad idea.
Surprisingly, for a lot of people this seems to be an impossible task. They come after the snake with a shovel, the snake protests in the only way it can, and hoots of “look its aGgReSsIvE!” fill the air (and local social feeds) … and the feedback loop continues.
Blacktailed Rattlesnake With A Friend
I found this young Blacktailed Rattlesnake resting under the dried-out husk of a small mammal (skunk?) in a cave near Phoenix on a survey of lands managed by Desert Foothills Land Trust.
In wet years, this small cave fills with water from a few inches to around a foot deep. It becomes putrid slop, full of javelina feces and dozens of animals hiding from the heat. This small mammal had died in that water, eventually settling against this wall. This summer, the cave was bone dry. But, the dozen or so rattlesnakes that aestivate here each year still showed up.
Mojave Rattlesnake With Clear ID Characteristics
A Mojave Rattlesnake from the Phoenix area. These snakes are common in the flatter, creosote and grassland areas of the state. This one obeys the all the ID rules, with much wider white tail bands than black, yellow proximal rattle segment, and a post-ocular stripe that extends back to never intersect with the mouth.
Arizona Ridgenosed Rattlesnake
An Arizona Ridgenosed Rattlesnake we saw after dark in southeastern Arizona. These small snakes are great at hiding, and the locals rarely even know they exist.
Flat Headed Bromeliad Frog
One of the many large treefrogs one can find in the understory of the Peruvian Amazon on a night hike.
Arizona Black Rattlesnake from Greenlee County
Arizona Black Rattlesnakes are amazingly variable in appearance across their range. Most that are seen and photographed are in the relatively well-populated areas of the Mogollon Rim between Flagstaff, Prescott, and Payson. In other parts of their range, however, they look a bit less familiar. This one from the far eastern end of their range in largely inaccessible ranges of Greenlee County has a much messier, mottled look than is typically expected of the species, but common in the area.
