What’s the difference between a Gopher snake and a Rattlesnake?

Gopher snakes lack a rattle, are longer and more slender than rattlesnakes, have narrow heads, round pupils, no pits, and are non-venomous. On the other hand, rattlesnakes have a rattle, spade-shaped heads, slit-like pupils, heat-sensing “pits” near their nostrils, and are venomous.

If you’ve ever found yourself debating whether you’re looking at a neighborhood-friendly gopher or a potentially lethal rattlesnake, you know how crucial it is to distinguish between them. The harmless gopher snake is often killed due to this confusion.

So, how do you tell if you’re looking at a harmful gopher or a potentially lethal rattlesnake? It turns out there are some pretty easy hacks to tell them apart. After extensive research, here are gopher snake vs rattlesnake 10 Key Differences Answered!

You should not take any chances when distinguishing between gopher snake and rattlesnake. Check out these 10 key differences answered.

Difference #1: The Rattle

The rattle located on the end of a rattlesnake’s body is absent in gopher snakes. On the other hand, adult rattlesnakes generally have a good-sized rattle near the blunt end of their tail.

While rattlesnakes are the true rattlers, a gopher snake mimics the rattling to scare off threats. This is accomplished by shaking its rear in the manner of a rattler. The sound is produced when the tail rubs against the ground or dry vegetation.

However, some rattlesnakes lose their rattles due to various environmental factors. Thus, don’t assume that you’re looking at a gopher snake because there is no rattle.

To confirm, check the apex of the tail. In gopher snakes, the tail tapers to a thin, pointed end, while in rattlesnakes, the scales modify into a cluster ending in a blunt, rounded shape.

Difference #2: Overall Size

When an adult rattlesnake is placed next to a fully grown gopher snake, the latter wins the size contest. The average adult gopher snake size is 6 to 9 feet long; most reach 8 feet. Rattlesnakes range from 3 to 6 feet, depending on the species.

However, while being almost twice the length of rattlers, gopher snakes have a significantly narrower girth. Rattlesnakes are heavy-bodied, while gopher snakes are whip-like.

Difference #3: Head

The size of the head is another differentiating feature between the two snake species. A rattlesnake’s head is shaped more like an arrow or triangular shape, like a pit viper. This makes the head notably more prominent than its slender neck.

Herpetologists ascribe the difference in head size to the huge venom glands at the rear of their heads. Because gopher snakes are constrictors, they lack venom glands, resulting in heads as slender as their necks.

Difference #4: Shape of the Pupils

The pupils of a rattlesnake are vertical, as they are in all viper species. On the flip side, the pupils of a gopher snake are spherical.

But to tell the difference, you’d have to get too close for your liking. This could be achievable if the serpent is kept in a cage. But if you’ve just discovered it in your yard, you can see why this would be an issue.

Difference #5: Venom

One of the primary distinctions between a gopher snake vs rattlesnake is their venom. Gophers are non-venomous, and while they may bite you (usually in defense), it is completely harmless.

Crossing to the other side, rattlesnakes have venom that’s produced in glands located in the snake’s upper jaw. Their venom is a complex mixture of chemicals, yet a bite is rarely lethal.

Aside from the horrific bleeding from the bite site, the victim’s blood pressure plummets dramatically. And if left untreated, it can kill a fully-grown adult. As a result, a rattlesnake bite is considered a medical emergency.

Difference #6: How they kill

Gopher snakes and rattlesnakes frequently compete for territory and food. Their primary food sources include rabbits, squirrels, ground-nesting birds, mice, and other rodents. The key difference is in the hunting and feeding method.

Rattlesnakes ambush their victim. They wait for the right moment and attack. They kill the prey with a lethal bite before devouring it whole. Gopher snakes hunt with their excellent sense of smell. When they strike, they coil around the animal, effectively constricting it to death.

Rattlesnakes have two enormous fangs on their upper jaw to inject venom. Gopher snakes lack fangs because they are constrictors. Instead, they have numerous tiny, hooked teeth for gripping their prey while they squeeze it.

Difference #7: Dorsal Pattern

To people unfamiliar with common snake breeds, a gopher snake vs rattlesnake might look alike. But if you were to look close enough, you would notice a difference in the color and pattern of the bodies of the snakes.

Color is quite a variable in gopher snakes vs rattlesnakes, but there is a notable difference in the dorsal design. The Gopher has a dark checkered pattern that looks like a chain of squares or rectangles. But most rattlesnake species have a distinct diamond dorsal pattern.

Difference #8: Location

The range of the gopher snake is extensive. They inhabit coniferous forests, brushlands, woodlands, prairies, deserts, and cultivated fields. Geographically, this means they can be found in most states. They are one of the most widespread species in the US.

According to the University of Michigan’s Animal Diversity Web (ADW), you can spot gopher snakes from north of Mexico to Western and South Central Canada. They can be found west to the Pacific coast, West Texas, Missouri, Illinois, north through Wisconsin, Saskatchewan to southern British Columbia.

Rattlesnakes occupy deserts, marshes, plains, woodlands, and foothills. They are abundant in the deserts of the southwestern United States but range from southern Canada to central Argentina.

Difference #9: Breeding and Reproduction

When it comes to the reproductive behavior of these snakes, one is oviparous (lays eggs) while the latter is ovoviviparous (gives birth).

Gopher snakes mate during spring, right after hibernation. After about 8 weeks, pregnant females lay eggs that hatch after another 8 weeks. Rattlesnakes are one of the few snakes that give birth to live young.

Although they don’t hibernate through winter, rattlesnakes also breed in spring. This species lays eggs but keeps them incubated for about 7 months until they hatch and come out as snakelets.

Difference #10: Defensive Behavior

Now here is where all the intrigue lies. Indeed if a snake shakes its tail, it’s got to be a rattlesnake. Not necessarily. The gopher snake has mastered the art of mimicry.

Gophers morph their heads to resemble that of a rattlesnake. They have loosely connected jawbones that enable them to flatten out their heads into a triangular shape. They will also hiss and vibrate the tail when agitated, just like an original rattler.

Do Gopher Snakes Eat Rattlesnakes?

Yes, a Gopher snake can eat a rattlesnake. Gopher snakes excel in climbing, swimming, and burrowing. This allows for a more diverse diet.

The rattlesnake occasionally appears on the gopher’s menu in addition to insects, lizards, small animals, birds, and their eggs.

Because they compete for food and territory with rattlesnakes, you won’t typically find both in the same area. For this reason, gopher snakes will help keep rattlers away. But they will only go after a threatening rattler or if it is hungry.

The hunting method varies when the rattlesnake is the prey. The gopher snake lays in wait and strikes when ready. But instead of the usual constriction method, the Gopher grabs the rattlesnake by the head and suffocates it before swallowing it from head to tail.

What to Do When You See a Rattlesnake

If the serpent you’re looking at is a rattlesnake by some chance, you must exercise caution to avoid a trip to the ER. Here’s what to do when you see a rattlesnake.

  1. Don’t panic; don’t scream, and don’t run away – remain calm.
  2. Ensure there are at least 5 ft between you and the snake.
  3. Coiled, rattling, and head raised? If possible, step back to increase the striking distance. It’s best to stand at about 15 ft from the viper.
  4. Hold your ground and stand still for a few minutes. Rattlesnakes are not aggressive and will likely slither away once they establish you are not a threat.
  5. If a bite occurs, stay calm, call 911, and request medical assistance.
