You’re scrolling through your phone, looking at images of a rat snake because you just saw a long, dark shape vanish into your flowerbed. It’s a heart-pounding moment. Most people immediately think "copperhead" or "rattlesnake." Usually, they’re wrong. Rat snakes are the ultimate masters of the "frighten-everyone-by-accident" game. They’re big. They’re often dark. Honestly, they’re kind of goofy once you get to know them, but when you're looking at a high-res photo of one coiled up, they look like something out of a jungle movie.
Identifying the Real Deal in Rat Snake Photos
When you start digging into images of a rat snake, the first thing you'll notice is the sheer variety. We aren’t talking about one single look. Depending on whether you're looking at a Black Rat Snake (Pantherophis alleghaniensis) or a Yellow Rat Snake from the coast, the visual profile shifts completely.
Look at the head. That’s the giveaway.
In almost every clear photo, you’ll see a head that is only slightly wider than the neck. It’s shaped sort of like a loaf of bread. If the snake in the photo has a massive, distinct triangular head and deep pits between the eyes and nostrils, you aren't looking at a rat snake. You’re looking at a pit viper. Rat snakes have round pupils. Simple as that. If you see vertical "cat eyes" in those images of a rat snake, someone mislabeled the file.
The scales are another tell. Rat snakes have "keeled" scales. This means there is a tiny ridge down the center of each scale. In the right lighting, this makes the snake look less like shiny patent leather and more like a textured fabric. It’s a subtle detail, but it’s why they don't look as "slick" as a Black Racer, which has smooth scales and reflects light like a mirror.
The Weird "Kinked" Pose
Have you ever seen a photo where the snake looks like it went through a crimping iron? It’s bizarre.
This is a classic rat snake behavior. When they feel threatened or just want to blend into a branch, they crinkle their bodies into a series of tight "S" curves. It breaks up their outline. If you find images of a rat snake looking like a jagged piece of rope, it’s not injured. It’s just trying to be invisible. They are remarkably good at it, too. You could be staring right at one in a woodpile and never see it until it moves.
Why Location Changes Everything
Geography dictates what your "local" rat snake looks like. If you’re in the Northeast, your photos will show heavy, black-bodied snakes with white chins. Down in Florida? You’re looking at something orange or yellow with four dark longitudinal stripes.

It’s the same species complex, just different "paint jobs" for different environments.
- The Gray Rat Snake: Common in the Central US. These guys keep their blotchy juvenile pattern even as adults. They look a lot like corn snakes, which makes sense because corn snakes are actually a type of rat snake.
- The Texas Rat Snake: These can be feisty. Photos often show them with white or red skin showing between their dark scales when they puff up.
- The Everglades Rat Snake: A bright, beautiful orange. People often mistake these for escaped pets because they look too "tropical" for the backyard.
The Climbing Expertise
You won't just find these snakes on the ground. A huge chunk of the images of a rat snake circulating online show them in places snakes shouldn't be.
Like birdhouses.
Or your rafters.
Or literally vertical brick walls.
They have specialized belly scales that act like little treads on a tire. They can find the tiniest bit of purchase on a flat surface and hoist themselves up. I once saw a photo of a rat snake five feet up a brick wall, perfectly horizontal, just looking for a bird’s nest. They’re basically the Spiderman of the reptile world. If you see a large snake in a tree, it is almost certainly a rat snake. Water moccasins and copperheads aren't exactly known for their Olympic-level climbing skills, though they can climb if they really have to. Rat snakes do it for fun. And eggs. Mostly eggs.
Common Misidentifications That Cause Panic
The internet is full of "snake ID" groups where people post blurry images of a rat snake convinced it’s a Black Mamba. (Spoiler: It’s never a Black Mamba in North America).
The most common mix-up is with the Northern Water Snake. Water snakes are thick, grumpy, and have bands that go all the way around. Rat snakes have a checkered or plain white belly. If you’re looking at a photo and the snake is in the water with its whole body floating on the surface, it might be a water snake. Rat snakes swim, but they usually look a bit more awkward doing it.
Then there’s the "Black Racer" confusion.

Racers are thin. They are fast. They are incredibly smooth. Rat snakes are "heavier" built. Think of a Racer as a sports car and a Rat Snake as a dependable SUV. If the photo shows a snake with a white chin but a very "matte" or textured black body, it’s a rat snake. If the snake looks like it was dipped in liquid obsidian and has a white patch only on the very tip of its chin, it’s a Racer.
Juvenile Snakes Look Nothing Like Adults
This is where people get tripped up. Baby rat snakes aren't black or yellow. They are gray with bold, dark brown blotches.
If you look at images of a rat snake hatchling, you’d swear it was a copperhead or a timber rattlesnake. This is likely an evolutionary trick called mimicry. By looking like something dangerous, the babies survive long enough to grow into the big, mostly-harmless adults. To tell the difference, look at the tail. Rat snakes have a thin, tapering tail. They don't have a rattle, though they will vibrate their tail against dry leaves to sound like one. It’s a very convincing bluff.
The Ecological Value of a Rat Snake
Seeing images of a rat snake on your property shouldn't be a reason to call pest control. Honestly, they are the pest control.
They are named "rat snakes" for a reason. They have a high metabolism and a huge appetite for rodents. A single large rat snake can keep an entire barn free of mice and rats over a summer. They are non-venomous constrictors. They grab the prey, wrap around it, and it’s over.
Some people get upset because they also eat bird eggs. Yes, if you have a purple martin house or a bluebird box, a rat snake will eventually find it. It’s part of the cycle. You can prevent this with "wobble" baffles on your poles, but don't blame the snake for being a snake. They are just following the scent of a meal.
Behavior and "Temperament"
If you’ve seen videos or images of a rat snake being handled, you might see them gape their mouths open. They have a white interior to their mouth, which can look a bit like a cottonmouth if you’re panicking. But they aren't aggressive. They are defensive.

If you corner a rat snake, it will hiss. It will strike. It might even musk on you—which is a foul-smelling liquid they release from their vent. It smells like rotting cabbage and skunk. It’s disgusting. But it’s not dangerous. Most of the time, if you give them six feet of space, they will just move along to the nearest hole or tree.
How to Get Good Photos of One
If you happen to find one and want to contribute to citizen science or just show your friends, there’s a right way to take images of a rat snake.
First, don't get too close. Use your zoom. A snake that feels crowded will coil up or flee, and you won't get a natural shot.
Second, try to get a clear shot of the head and the mid-body scales. This helps experts on sites like iNaturalist or Reddit's r/whatsthissnake give you a 100% certain ID. If you can see the eye and the pattern on the side, you’re golden.
Third, look for the belly. If the snake is moving, you might see a "checkerboard" pattern of black and white or yellow and white. This is a hallmark of many rat snake subspecies. It’s like a fingerprint.
Actionable Steps for Homeowners
If you’ve identified a rat snake in your yard through these tips, here is what you should actually do:
- Leave it alone. It is providing free labor by eating rodents that would otherwise be in your pantry.
- Seal your house. If you're worried about them getting inside, check your foundation. Rat snakes can get through any hole larger than a quarter. Use hardware cloth or expandable foam to seal gaps where pipes enter the home.
- Check your birdhouses. If you have nests you want to protect, install a stovepipe baffle on the pole. A simple 4-inch PVC pipe or a specialized metal baffle will stop them from climbing.
- Remove hiding spots. Piles of firewood or scrap metal near the house are basically luxury apartments for snakes. Move these at least 20 feet away from your foundation.
- Educate the neighbors. Many people kill these snakes out of fear. Sharing your images of a rat snake and explaining their benefits can save their lives and keep the local ecosystem balanced.
These snakes have lived alongside humans for thousands of years. They are adapted to our barns, our suburbs, and our gardens. They aren't looking for a fight; they’re looking for a meal and a warm spot to shed their skin. When you see one, take it as a compliment to your yard’s biodiversity. You've got a healthy environment. Enjoy the sighting, take a photo from a distance, and let the Spiderman of the snake world go back to work.
