Questions About Snakes

Tennessee Snakes (Species List, Identification, Location + Most Active)!

There are many snake species in Tennessee. Unfortunately, identifying snakes can be difficult because lots of species are similar in color, pattern, and where they’re found.

What are the different types of snakes in Tennessee? The state has 34 species in total. 4 are venomous, the cottonmouth, pygmy rattlesnake, timber rattlesnake, and copperhead. The most common non-venomous snakes include water snakes, garter snakes, ringneck snakes, and rat snakes. Snakes live near cities like Nashville, Memphis, and Knoxville but also out in the country.

During Tennessee snake season, you can expect to find most of these species. Learning to identify snakes in Tennessee will help you avoid the venomous ones so that you can stay safe.

When are Snakes Most Active in Tennessee?

Snake season in Tennessee runs from the early spring, through the summer and up to the fall. That’s when snakes are most active. So, if you want to find snakes, spring or summer is the time to do it.

Snakes are vulnerable to temperature changes because they’re cold-blooded. If they were to stay outside during a freezing winter, they would die. So, they go through the reptile process analogous to hibernation, called brumation.

Like other animals that hibernate, they come out when it’s warm again in the spring. At this time, they’re very hungry, so they hunt a lot. It’s also mating season, so they’re especially active. Mating season runs through to summer.

Snakes will still be active, but not quite as active, through late summer and the fall. They will go back into hibernation when the temperature starts to hit freezing again. Then they’ll do it again next year.

List of Snakes in Tennessee

There are around 34 native species in total, of which 4 are venomous. The exact number depends on whether you count individual species, or the subspecies too, in which case there are more.

Here’s a list of every snake. If you want to identify snakes in Tennessee, we’ve also included a brief description of each one. We’ll look at the most interesting ones in more depth.

Any Invasive Species of Snake in Tennessee?

In many states, there are invasive snake species. These are species that aren’t native to the state, or even to the U.S. They are introduced by pet owners who accidentally or purposefully release them into the wild. Or, they may have escaped from research facilities.

The most famous example is the Burmese python. It’s from Burma, now known as Myanmar, in Southeast Asia. It’s now common in the Florida Everglades after specimens escaped from a zoo during a hurricane.

Fortunately, there are no known invasive snake species in Tennessee. That’s a good thing, because invasive species attack native species, or eat all of their prey. This can make native species go extinct.

Is It Illegal to Kill Snakes in Tennessee?

In Tennessee, you’re not allowed to harm, kill or collect native snakes from the wild. You’re only allowed to if you have a permit from the state. Contact the Tennessee Wildlife Resources Agency for more information.

But what a lot of people don’t appreciate is that you don’t need to kill wild snakes. The vast majority of snakes you’ll encounter will be non-venomous. These snakes are harmless to people, although their bites might hurt if you threaten them.

Even better, these snakes are helpful to people. They kill rodents, which are agricultural pests as well as a nuisance. Without them, the rodent population in suburban areas could get out of control. And the impact on farming would be awful.

And while there are venomous snakes in the state, it’s better not to kill these, too. That’s because you’re far safer trying to avoid the snake than trying to attack it. Even venomous snakes don’t seek out fights with people. They’d much rather avoid you, too.

Venomous Snakes in Tennessee

Of the thirty-four snake species in Tennessee, only four are venomous. But even though Tennessee isn’t known for its deadly snakes, these species do pack a punch. Some of them can even kill if you don’t receive prompt medical attention.

1) Copperhead

They get their name from their rusty red head. The front half of their body has lots of red pigmentation, too.

Their venom isn’t as potent as that of a rattler, but does still hurt and should be treated by a medical professional. A copperhead won’t kill you unless you have a severe reaction.

But people are far more afraid of copperheads than they need to be. They aren’t aggressive unless you antagonize them. That doesn’t stop this snake from being the leading cause of snakebite in the U.S. But according to the Journal of the American College of Surgeons, bites aren’t as serious as those of, say, rattlesnakes.

Where is the Copperhead Snake Found?

Copperheads are common in woodlands across the entirety of Tennessee. They’re a regular sight for anyone that takes lots of trails and long walks. They’re also frequently found in most states along the eastern seaboard, and as far west as West Texas.

2) Timber Rattlesnake

Timber rattlesnakes are the most dangerous snake in Tennessee. Like all rattlesnakes, timber rattlesnakes are pit vipers. This places them in a family of the most dangerous snakes in the world.

Their deadliness is down to two things. The first is their potent venom. Their venom can destroy muscle tissue immediately after it’s injected. The trouble is that it affects muscles like the heart and lungs, stopping both from working. That’s obviously deadly.

But as well, timber rattlesnakes have lots of venom. Have you ever looked at how wide their jaw is compared to its neck? That’s because that’s where snakes have their venom glands. A timber rattlesnake’s venom glands are huge, so it has lots of venom. This makes it even deadlier.

As for spotting one, that’s easy. They have a distinctive banded pattern of dark brown on light brown or gray. But their most obvious feature is their rattle, which makes a loud buzzing sound.

Where Is the Timber Rattlesnake Found in Tennessee?

Most snakes get their name either from a distinguishing feature, or from where you’re likely to find them. As you can imagine, the timber rattlesnake can be found in forests.

As for their range, you can find them all across Tennessee. They compete for the same habitats as copperheads.

3) Western Cottonmouth

Cottonmouths spend most of their time near water, and are adept swimmers. They’re exceptionally fat for a snake, with short, stout-looking bodies.

But it’s their defensive display that gives them their names. Cottonmouths got their name because they open their mouths wide when threatened. The lining of their mouth is a bright white, the point of which is to dazzle and confuse potential predators/threats.

are there snakes in Tennessee lakes?

Where Is the Cottonmouth Found in Tennessee?

Cottonmouths have a smaller range than copperheads. They can be found only in the western third of Tennessee.

4) Pygmy Rattlesnake

Pygmy rattlesnakes are in the same family as other rattlers. The only difference is that they’re a lot smaller, as the name suggests. They reach an average length of 16 to 24 inches, so may not even reach two feet. The biggest is two and a half feet.

Its coloration is unique among rattlesnakes. The pygmy rattlesnake has a light blue-gray background color with black blotches along its back. Between these black blotches, linking them, is a red stripe running along their back.

And like all other rattlers, the pygmy rattlesnake has a rattle. It’s smaller, but it still makes a loud buzzing noise.

Where Is the Pygmy Rattlesnake Found in Tennessee?

This snake likes a range of habitats, including flatwoods, forests, and marshes. But despite being comfortable in many different ecological systems, you’ll only find it in the far west of the state.

Most Common Snakes in Tennessee

These four venomous snakes aren’t the most common in the state, though. Non-venomous snakes usually outnumber venomous snakes. Usually, when you see a snake out in the wild, it’s not a dangerous one.

The eight species below are the most common. As stated above, there are 30 total non-venomous species. But some are far less commonly encountered than others, or are only present in isolated and select parts of the state.

None of the species below has venom. It’s not that each species only has a little, or that it doesn’t affect people. It’s that each species doesn’t have venom glands, or fangs capable of delivering venom. They can’t kill you.

But that doesn’t mean that a bite from one of these species won’t hurt!

1) Common Watersnake

The common water snake, also known as the northern water snake, loves water. If you want to find one, head to your nearest lake or pond. If there are any there, you’ll spot them basking on rocks or tree stumps.

This snake isn’t anything special when it comes to color. Each one is a shade of brown with darker brown saddles that run along its back. It looks almost like it’s covered in brown camo.

If you’re lucky, you might see this snake swimming or hunting. It hunts among plants on the water’s edge, looking for prey like:

  • Tiny fish
  • Frogs and toads
  • Worms and leeches

It will also eat small birds and mammals, like many other snakes of a similar size. But don’t get too close. If you do, it will dive into the water and swim away as quickly as it can. It doesn’t like confrontation with bigger animals like people, but its bite is painful if you corner it.

Where Can You Find Watersnakes in Tennessee?

It might make sense to rename this snake—it’s less a ‘northern’ snake and more an ‘eastern’ snake. It’s found across the entirety of Tennessee. But more broadly speaking, it’s found in almost every state along the eastern seaboard, and most states east of the Midwest.

So, if you want to find one, head to your nearest pond or lake. They’re everywhere across Tennessee.

2) De Kay’s Brownsnake

Dekay’s brownsnake is an earthy, woody brown color. Its underside is a paler cream color, but isn’t very high contrast. It has the occasional fleck of darker brown in its scales. Sometimes these are high contrast flecks that are much darker, sometimes they’re less noticeable.

It’s also got a slightly lighter stripe running along its back, flanked by two thinner, darker stripes. You may not see these until you get up close. Again, its pattern isn’t supposed to be of high contrast. But what does distinguish this snake is that it’s tiny, usually shorter than a foot long.

One of the ways to identify a Dekay’s brownsnake is that they musk when threatened. Musking is a defense mechanism whereby the snake secretes (or even shoots out) a foul-smelling fluid from an anal gland. It smells as pleasant as it sounds.

Where Can You Find De Kay’s Brownsnake in Tennessee?

Again, these snakes are common across the entirety of Tennessee.

They are native all across eastern North America, and you can even find some in Canada. And if you want to go traveling, you can find it throughout Mexico, Guatemala, Honduras, and maybe El Salvador. It’s a common snake.

If you want to go out and find one, check in a variety of habitats. They like grassland and forest, and can often be found lounging at the side of water sources.

3) Eastern Garter Snake

Unlike De Kay’s brownsnake above, this snake is immediately noticeable and striking to look at. It’s highly variable in color, but most garter snakes are black and yellow or black and white. They exhibit:

  • A pale cream stripe along their back
  • An underside of the same color
  • The background color of a darker brown shade
  • Flecking of various degrees along their background color, of the same pale cream color as before

The contrast between their stripes, as well as the flecking they have, makes them high contrast. They’re immediately obvious even to a beginner (except when they’re somewhere they can camouflage themselves).

The garter snake clocks in at between one and a half and two and a half feet, so it’s an average-to-short size for a snake.

Where Can You Find Garter Snakes in Tennessee?

This snake is exceptionally common. Like the other species in this list, it’s found all across Tennessee.

It’s one of the most common snakes in North America. Garter snakes are found in almost every one of the continental United States. The eastern garter snake, which we have in Tennessee, is found in every state east of Texas (as well as Canada).

Because they’re so common, garter snakes are often people’s first experience with snakes. They’re also a common first pet snake. If you want to find one, check all the regular habitats, like grasslands, woodlands, and next to water sources.

4) Eastern Black Kingsnake

This is another snake that’s beautiful to look at. It’s a glossy black snake with a paler underbelly. Where the underbelly and sides meet, the pale color turns into diffuse and irregular flecks. The overall effect is striking.

Like many snake species, juvenile specimens have a brighter pattern and color combination. A juvenile eastern black kingsnake has pale white or yellow banding that will fade to black as it matures.

Where Can You Find Kingsnakes in Tennessee?

Again, this snake is common to every county in Tennessee. It’s easy to find across all of the south-eastern U.S.

Like most species, this snake lives in forests, agricultural lands, and near water sources (snakes need water too). You can find some in suburban areas around big cities like Nashville, Memphis, and Knoxville too.

when are snakes most active in Tennessee?

The only difference is that on the Kentucky border, the snake may have interbred with the speckled kingsnake. This snake isn’t considered a subspecies, but may be in the future if interbreeding continues. This is the only place that this unique king of kingsnake exists.

5) Gray Ratsnake/Chicken Snake

The gray rat snake looks a little like a darker garter snake specimen. It has a dark gray or black background color, with speckled lighter yellow or cream on its sides. The main difference between the two snakes is the lack of a striped back.

Another difference, though, is in size. This is one of the large snakes in Tennessee, as it can reach between three and six feet. The longest ever found and recorded, though, was over eight feet long.

Where Can You Find Chicken Snakes in Tennessee?

If you work on the land, you might find this snake in your chicken coop. It’s known for being crafty and finding its way into chicken coops, to feed to its heart’s content.

As for its habitat, this snake is most common in forests. You can find it all throughout the eastern and central United States, and all across Tennessee.

6) North American Racer/Eastern Racer

The eastern racer is a species of snake that varies in appearance. That’s because it has eleven subspecies, dotted around the country. Two of these subspecies are found in Tennessee: the Northern black racer and the Southern black racer.

Ironically, you won’t find these species in the north and south of the state respectively. Rather, you’ll find the Northern black racer in the eastern half of Tennessee, and the Southern black racer in the west.

Either way, these two subspecies look exactly the same. The only way to tell them apart is through internal anatomical differences. Both species are a glossy black snake, just like the black kingsnake. It can be difficult to tell these species apart as well. They reach between two and five feet in length.

Where Can You Find Racers in Tennessee?

It’s found throughout the United States almost everywhere east of the Rocky Mountains. You can also find it as far north as Canada, and as far south as Mexico and Central America. As you might imagine, then, this snake can be found almost anywhere in Tennessee.

7) Red Corn Snake

The red corn snake, or just the corn snake if you prefer, is another common snake. It’s a deep brick red color, with saddles along its back that are slightly darker. These saddles are ringed with a thin dark brown line.

Their underside is paler, contrasting nicely with the deeper, brighter color of their sides.

Where Can You Find Corn Snakes in Tennessee?

These snakes have been common in Tennessee for centuries. They get their name from their behavior: they were historically found near grain or corn stores, where there were lots of rodents. So if you live in an agricultural area, you may expect them to live nearby.

If you don’t, you’re still in luck. These snakes are mostly found in the western half of Tennessee. Head out to any forest or grassland and see if you can find one.

Aside from that, corn snakes are found all across the southeast United States. They’re a common first pet because of their pleasant disposition and easy care routines.

Are There Water Snakes in Tennessee?

There are plenty of water snakes in Tennessee. The two most common species are the cottonmouth and the common water snake. The cottonmouth is venomous while the common water snake is not.

However, other snake species hang around near water too. All snakes need to drink water, like any other animal. You’ll therefore frequently find most species near ponds, lakes, and rivers.

Snakes that live in water in Tennessee include the common water snake and the cottonmouth.

Are There Snakes in Tennessee Lakes?

While there are lots of Tennessee snakes near water, and can swim, that doesn’t mean they live in lakes. The only snakes that permanently live in water are sea snakes, and there are no species on the east coast of the United States (let alone inland in Tennessee).

Rather, these snakes spend their time at the water’s edge. Cottonmouths and common water snakes like to sun themselves on logs and rocky outcrops next to water. Then, when they want to hunt, they may skirt the water’s edge for a while and see what they can find.

Where to Find Snakes in Tennessee?

So, if you’re interested in searching for snakes in Tennessee, you’ll probably have lots of luck. There are many species that you can find all across the state. If you do decide to go looking for some, follow these tips:

  • Ideally, you’ll want several pieces of kit: a snake hook and bag, as well as protective equipment like thick leather boots and snake gaiters.
  • When searching under rocks and logs, use a stick or snake hook instead of your hands. You could disturb a venomous snake and get bitten.
  • If you find one venomous snake, there are likely to be others nearby too. Rattlesnakes live in loose groups near a communal den.
  • Search in different habitats to find different species. Try forests, grassland, and near water sources.
  • If you find a snake and it gets defensive, leave it alone. It won’t chase you to attack you.

Other than that, use your common sense and you’ll be fine.
