Camping and fishing along any waterway along the rim in Arizona, it’s common to see gartersnakes cruising around the vegetation. There are several species of gartersnakes in Arizona, but this may be the most commonly encountered. Wandering Gartersnakes are a subspecies of Western Terrestrial Gartersnake that inhabit a variety of habitat, though are most often spotted in shallow water going after tadpoles and small fish.
A Sonoran Whipsnake from near Phoenix, Arizona. These fast, diurnal animals can be seen on occasion darting across trails or roads, even in the peak heat of the day. Large, forward-facing eyes and a body style made for speed mean that any lizard that ends up in its sight isn’t going to have a good day.
They show up from time to time at homes at the very edges of the city. Based on our records of snake encounters at homes over the last 16 years, they are not as good at adapting to semi-developed areas as other, similar species, like coachwhips.
A few years ago, I saw what would be the only known record of one in the Piestewa Peak preserve area. It was in the middle of the night, resting in loose rocks in front of a spot where several Southwestern Speckled Rattlesnakes were about to give birth. Sonoran Whipsnakes include rattlesnakes in their diet, and I assumed it was waiting for that opportunity. Unfortunately, I chose to slowly reach for my camera rather than dive into to rocks to grab it, and it escaped without a photo record. So, an observation went into the notes for the night’s field session, but the preserve is still without an official record.

If you walk a stream in much of Arizona right now, there’s a good chance you’ll run into one of these. It’s a Black-necked Gartersnake, getting breath and a break between dives to eat tadpoles. In any of the isolated pools along this drainage, there may be one or two, filling up on these seasonal globs of protein while they can. This particular snake is a very small baby, likely not much different in age than the tadpoles it’s hunting.
A Sonoran Lyresnake seen late at night on a hike in a remote mountain range in extreme southwestern Arizona. These cryptic, nocturnal snakes live in rocky areas, where they take a variety of prey using venom. But, unless you’re a lizard, you have nothing to fear from this snake … if you ever even see one.
A Spotted Leafnosed Snake found late at night a couple of summers ago. While many snakes are tucked away in late May and June to wait for the monsoon, these snakes are very active. The reason: lizard eggs. These are reptile egg specialists, and June is a great time to be out looking for them to eat. The “leaf” on its nose is a kind of shovel, to help push through soil to get to them. They’re small snakes, less than a foot long typically, and entirely harmless. If captured, they may coil and strike repeatedly with a hiss, but if you look closely, their mouth is closed the entire time. It’s sometimes said that “anything with a mouth can bite”, but can and will aren’t the same thing.
A beast of a Lyresnake! These are typically slender snakes, but this has been very successful. At first it looked like a gophersnake, with a chunky build and round face. These are cryptic snakes that few people that live in Arizona, even born here, will ever see.
A California Kingsnake on the crawl late at night in central Arizona.
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.
Mexican Parrot Snake in the subtropical forest of southern Mexico.
The weird little face of a strange little snake. The Spotted Leafnosed Snake can be found in natural desert areas. Often, they are the only snakes moving on hot, dry, full moon nights in May and June, on the hunt for lizard eggs. The specialized scale on its nose, shaped like a leaf, helps it push through sand and soil to find them.
When disturbed, these small snakes may whip around, hissing and repeatedly faking a strike … though if you see it in slow motion, their mouths are closed the whole time. This is not a snake that bites.
