Mississippi is perfect for snakes. After all, it sounds like a noise a snake would make. Beyond ssssemantics, it is a subtropical southern state that shelters around 50 species of serpents, just six of which are significantly venomous. In contrast to nonvenomous species like the corn snake or negligibly venomous species like the hognose snake, these envenomators can kill humans鈥攂ut that does not mean they kill Mississippians. Keep reading to learn about said species and how safe the proverbial Hississippi actually is.

Copperhead

So-called because of its copper coloring, the medium-sized copperhead (Agkistrodon contortrix) is one of the hardest snakes to spot in its natural habitat, which comprises woody, rocky, and leafy areas across Mississippi. As such, residents are sometimes bitten after unknowingly trodding near鈥攐r on鈥攁 copperhead. This happened to an 18-month-old child in Hamilton, Mississippi in 2016. Fortunately the copperhead has the least significant venom of Mississippi's significantly venomous snakes. The child survived after receiving antivenin, as did a Philadelphia, Mississippi hunter who was bitten on the head by a rare arboreal copperhead in 2020. Fatal copperhead bites are uncommon if not entirely absent in the state. In states where fatalities do occur, the survival rate is still 99.99 percent. Its venom works much better on insects, lizards, and rodents.

Northern Cottonmouth

Like the copperhead and all snakes on this list save one, the northern cottonmouth (Agkistrodon piscivorus) is a pit viper, meaning it hunts with heat-sensing pits located between its eyes and nostrils. Separating the northern cottonmouth from other pit vipers, however, is its love of water. Sure, virtually all snakes can swim, but this stout species is a certified aquaphile. It can be found in lakes, rivers, creeks, ponds, marshes, swamps, and even salt water throughout Mississippi. Naturally, it eats fish and frogs.

Also separating the cottonmouth from other vipers is its cottonlike mouth tissue, which it displays to deter predators such as humans. If that doesn't work, a venomous bite might. Yet cottonmouth-caused fatalities are unheard of in modern Mississippi. The northern cottonmouth is one of two cottonmouth species in America. The other is the Florida cottonmouth, which lives in Florida and Georgia. However, the two cottonmouths have made a hybridization zone that includes part of Mississippi. Perhaps the state will soon have a seventh species of venomous snake.

Eastern Coral Snake

The eastern coral snake (Micrurus fulvius) is the only significantly venomous Mississippi serpent that is not a pit viper. It is an elapid, which puts it in the same family as cobras, mambas, and sea snakes. The eastern coral snake looks flashy but is actually introverted, preferring to hide underground while its cousins flaunt their hoods, speed, and swimming ability.

Moreover, though it can grow up to four feet long, it usually stays in the two-foot range鈥攕o small that its fangs might not be able to puncture a pant-covered leg. But if they do, get to the hospital immediately. Eastern coral snake venom is more toxic than that of all Mississippi snakes, but because of its size, docility, and notoriety ("red touches yellow, kill a fellow"), bites are rare and the only documented fatality since coral snake antivenin debuted in America happened in Florida. The "victim" was drunk and attacked the snake first. But his worst mistake was not seeking treatment.

Pygmy Rattlesnake

America's most famous pit viper is, of course, the rattlesnake. But when you picture that infamous reptile, you probably don't see one that, when coiled, is the size of a pine cone. Change your perspective for the pygmy rattlesnake (Sistrurus miliarius), the smallest species of rattler, averaging about a foot and a half in length. It occurs throughout Mississippi as two separate subspecies (although some sources say three). They are the dusky pygmy rattlesnake (Sistrurus miliarius barbouri) and western pygmy rattlesnake (Sistrurus miliarius streckeri). The latter tends to have fewer spots and brighter colors than the former. Both occupy a variety of habitats and eat small animals like insects and frogs.

Though the pygmy rattlesnake's venom is relatively toxic, so little is injected that fatal envenomations are nonexistent in Mississippi and the rest of America. That does not mean a bite should be taken lightly. Extreme pain is to be expected, as should bruising and swelling. Less common but still possible (especially without medical treatment) is necrosis and limb loss.

Timber Rattlesnake

The timber rattlesnake (Crotalus horridus) is known to many Mississippians as the canebrake rattlesnake. Appropriately, it prefers wooded, brushy areas from pine forests to cane thickets, where it preys on mice, squirrels, voles, and other small mammals. Roughly three times the length of a pygmy rattlesnake and capable of injecting several times as much venom, the timber is one of the most dangerous snakes in the state.

Yet again, that does not mean it is biting Mississippians left and right. The Mississippi Poison Control Center treats roughly 100 to 200 venomous snakebites per year. Approximately 60 percent are from the copperhead, 30 percent are from the cottonmouth, and 10 percent are from rattlesnakes. Unlike the first two, rattlesnakes produce the most distinctive warning sound in the reptile kingdom, which prevents countless bites.

However, in the last few decades in Mississippi, the only documented snakebite that at least partly contributed to a human death was from a rattlesnake. But, since the species wasn't identified, it was either a timber or the next and previous snake on this list.

Eastern Diamondback Rattlesnake

In 2000, an 80-year-old Lawrence County man got bitten by a rattlesnake, crashed his vehicle en route to the hospital, and died. Yes, that is the only snakebite-related fatality known to have occurred in Mississippi in decades (the then-managing director of the Mississippi Poison Control Center hadn't heard of another since he began working there in 1978). Lawrence County is in the rustic range of both the timber rattlesnake and the eastern diamondback rattlesnake (Crotalus adamanteus), the latter of which is deadlier. It is not just the largest venomous snake in Mississippi, it is the largest venomous snake in America.

Its inch-long fangs inject hundreds of milligrams of venom into rats, rabbits, and, occasionally, humans. But, like any Mississippi venomous snake, it bites only when threatened and, with treatment, your chance of survival is practically 100 percent.

Although Mississippi is slithering with 50-some species of snakes, only six are significantly venomous. They are the copperhead, northern cottonmouth, eastern coral snake, pygmy rattlesnake, timber rattlesnake, and eastern diamondback rattlesnake. Though their bites are medical emergencies, they have not caused a documented death in the state in decades. Education, antivenin, and the fact that many bites are "dry" (no venom gets injected) make Mississippians overwhelmingly safe from snakes.
