You’re hiking a dusty trail in the high desert, sun beating down on your neck, when you hear it. That dry, rhythmic buzzing coming from the scrub brush. Your heart hits your throat. You look down and see a thick, patterned body coiled and ready.
Is it a deadly pit viper or just a harmless neighbor doing a really good impression?
The rattlesnake vs gopher snake debate isn't just for biology nerds; it's a vital bit of trail wisdom that saves lives—usually the snake’s. Every year, thousands of beneficial gopher snakes are killed by well-meaning people who think they’re "protecting" their families from a venomous threat.
Honestly, the two look so similar at a glance that even experienced hikers get a little jumpy. But if you know what to look for, the differences are actually pretty glaring.
The Master of Deception: Why They Look Identical
Evolution is a trip. Gopher snakes (Pituophis catenifer) have spent thousands of years perfecting the art of "looking like someone you shouldn't mess with." This is called Batesian mimicry. Basically, if you’re a harmless snack for a hawk or a coyote, you’re better off looking like a venomous landmine.
They don't just copy the outfit; they copy the attitude.
The "Rattle" Without a Rattle
The most famous trick is the tail vibration. If a gopher snake feels cornered, it will shake its tail at a ridiculous speed. When that tail hits dry leaves or tall grass, it creates a sound that is nearly identical to a real rattlesnake.
But here’s the kicker: Gopher snakes have long, tapering tails that end in a sharp point.
Rattlesnakes have, well, rattles. Even baby rattlesnakes—which people often say are "more dangerous" (a common myth)—will have at least one "button" at the end of their tail. If the tail is pointy like a needle, it’s not a rattlesnake.
The Head Shape Illusion
You’ve probably heard the old "triangular head means venomous" rule.
Forget it. It’s a terrible rule.
When a gopher snake gets angry, it actually flattens its head to appear wider and more triangular. It’s a bluff. While a rattlesnake’s head is naturally chunky because of the venom glands behind the eyes, the gopher snake is just putting on a show.
Instead of looking at the shape, look at the eyes. If you’re close enough to see (and please, don’t get too close), a rattlesnake has vertical, slit-like "cat pupils." A gopher snake has round pupils, just like yours.
Breaking Down the Physical Details
If you aren't sure, check the patterns and the "face."
The Eyes and Face:
Rattlesnakes are pit vipers. This means they have visible heat-sensing pits between their eyes and nostrils. From a distance, it looks like they have four nostrils. Gopher snakes lack these pits. Also, most gopher snakes have a dark line that runs from the top of their head, through the eye, down to the jaw. It looks a bit like they’re wearing messy eyeliner.
The Body Type:
Think of a rattlesnake as a heavy-duty truck. They are thick, heavy-bodied, and usually "low riders." Gopher snakes are more like sports cars—long, lean, and agile. A gopher snake can easily reach six to eight feet in length, while most rattlesnakes (depending on the species) top out around three to five feet.
The Scales:
Both have "keeled" scales, which means there’s a little ridge down the middle of each scale that makes them look dull rather than shiny. This helps them blend into the dirt. However, gopher snake patterns tend to be more "checkerboard" or blotchy, whereas many rattlesnakes, like the Western Diamondback, have very distinct, crisp diamond shapes.
Behavior: Who’s More Aggressive?
Neither.
Seriously. Neither of these snakes wants anything to do with you. You aren't food, and you're a giant predator to them.
A rattlesnake’s rattle is a "please stay away" alarm. They’d much rather you walk past them than have to waste their precious venom on something they can’t eat. Most bites happen when people try to kill the snake or pick it up.
Gopher snakes are a bit more "theatrical." They will hiss—loudly—by using a special flap of tissue in their throat called a glottis. It sounds like air escaping a tire. They might even do a mock strike where they lunge at you with a closed mouth. It’s all a big "tough guy" act to get you to leave.
The Diet Factor
Both snakes are actually huge allies for homeowners.
- Gopher Snakes: As the name suggests, they love gophers. They also eat rats, mice, and even small rabbits. They are constrictors, meaning they squeeze their prey.
- Rattlesnakes: They also eat rodents but use their venom to immobilize the meal before swallowing it.
If you have a gopher snake in your yard, you have free, non-toxic pest control. Honestly, keeping them around is the best way to ensure you don't have a rodent problem that attracts actual rattlesnakes.

What to Do When You Spot One
If you see a snake on the trail, the "three-step rule" is your best friend. Take three big steps back.
You are now out of the strike range of basically any North American snake. Take a photo, admire the pattern, and then just walk around it. Give it a wide berth.
If you find a snake in your yard and you're 100% sure it’s a gopher snake, just let it be. If you think it’s a rattlesnake, don't play hero with a shovel. Call a professional relocation service. Many "rattlesnake removers" are actually just snake enthusiasts who will safely move the animal to a nearby wash or field without hurting it.
Actionable Identification Checklist
When you're looking at that rattlesnake vs gopher snake in the wild, run through this mental list:
- Look at the tail: Is there a rattle or a blunt "button"? Or does it taper to a sharp, thin point?
- Check the movement: Gopher snakes are often faster and more "nervous." Rattlesnakes tend to move with a slow, heavy confidence or stay perfectly still.
- The Head: Is the head significantly wider than the neck (Rattler), or is it roughly the same width until the snake starts "acting" tough (Gopher)?
- The Noise: Is it a mechanical-sounding buzz (Rattler) or a vocal-sounding "Hiss" (Gopher)?
Identifying these animals correctly isn't just about safety; it's about respecting the ecosystem. Gopher snakes are often the "good guys" that get caught in the crossfire of our fear. Once you see the difference in their faces—the "grumpy" brow of a rattlesnake versus the "surprised" look of a gopher snake—you’ll never confuse them again.
Next time you’re out, keep your eyes on the sunny spots where they like to bask. Carry a walking stick to poke into thick brush before you step, and always keep your dogs on a leash in snake country. Education is the best antivenom.
Practical Next Steps:
- Download a local field guide app: Apps like iNaturalist or Seek can help you identify snakes in your specific zip code.
- Inspect your perimeter: Clear out tall weeds and woodpiles near your house if you want to discourage snakes from hanging out too close to your door.
- Learn the "local" look: A Pacific Gopher Snake looks different than a Great Basin Gopher Snake. Check photos of the specific subspecies in your county to sharpen your ID skills.
