South Carolina, a state renowned for its rich biodiversity, plays host to an array of wildlife, including six venomous snake species. This diverse snake population contributes significantly to the state’s unique ecological balance. While snakes often induce fear, understanding them is crucial, as many are non-threatening and play essential roles in our environment.
South Carolina is home to venomous snakes like the Eastern Diamondback Rattlesnake, Timber Rattlesnake, Eastern Coral Snake, Copperhead, Cottonmouth (Water Moccasin), and Pigmy Rattlesnake. These species, while dangerous, are an integral part of South Carolina’s varied ecosystem, emphasizing the need for awareness and precaution.
These species present a potential danger due to their venom, yet they are also an essential part of the ecosystem, controlling pests and contributing to biodiversity. To coexist safely, knowledge about these creatures, their habitats, and the potential threats they pose is invaluable.
Venomous Snake Basics
Difference Between Venomous and Non-Venomous
Venomous snakes are distinguished from non-venomous species by their specialized venom glands connected to fangs. When they bite, venom, a complex cocktail of proteins and enzymes, is injected into the victim. On the other hand, non-venomous snakes lack these glands, posing less risk to humans.
Venom Impact on Humans
Snake venom can have varying effects on humans, depending on the snake species and the amount of venom injected. Effects range from local symptoms like swelling and pain, to systemic symptoms like nausea, blurred vision, or even organ failure in severe cases.
South Carolina’s Biodiversity
Overview of Snake Species
In South Carolina, you’ll find a diverse range of snake species, venomous and non-venomous alike. Among these, six venomous species pose potential risks to humans.
Snake Habitats
Different snake species prefer different habitats. Some venomous snakes in South Carolina are commonly found in wooded areas, marshlands, and near water bodies.
Venomous Snake 1: Eastern Diamondback Rattlesnake
Characteristics and Identifiers
The Eastern Diamondback Rattlesnake, scientifically known as Crotalus adamanteus, is a heavy-bodied rattlesnake species. It is recognized as the largest venomous snake in North America, with adults often exceeding five feet in length. Its unique body patterns, which include a series of dark diamond-shaped blotches on its back, make it easily identifiable. These blotches are outlined with lighter scales, adding to its striking appearance. The snake is equipped with a set of hollow fangs through which it delivers its venom.
Habitat in South Carolina
The Eastern Diamondback Rattlesnake is a predominant resident of South Carolina’s coastal plain areas. These snakes have a preference for dry, sandy, or pine flatwoods habitats. They are often found in palmetto thickets and gopher tortoise burrows, where they seek refuge and hunt for prey.
Potential Danger Level
Despite their intimidating presence, Eastern Diamondbacks are generally non-aggressive and would rather avoid confrontation. However, if they feel threatened or cornered, they won’t hesitate to defend themselves. Their venom is highly toxic and can be fatal to humans if untreated. Symptoms of a Diamondback bite can range from swelling and severe pain to more severe systemic symptoms like blurred vision, difficulty in breathing, and even cardiac arrest.
Venomous Snake 2: Timber Rattlesnake
Characteristics and Identifiers
The Timber Rattlesnake, or Crotalus horridus, is another venomous pit viper species found in South Carolina. This snake, while not as large as the Eastern Diamondback, can still reach lengths of up to 5 feet. It is known for its characteristic pattern of dark crossbands or chevrons against a lighter background color, which can vary from yellow to black.
Habitat in South Carolina
Timber Rattlesnakes are usually seen in deciduous forests and rugged terrain in the mountainous regions of South Carolina. They often prefer areas with abundant sunlight for basking and large rocks or logs under which they can hide.
Potential Danger Level
The Timber Rattlesnake is generally a shy species and tends to avoid human interaction. However, if disturbed or threatened, it will respond with a potentially lethal bite. The venom of a Timber Rattlesnake is potent and can cause serious damage to tissues and blood cells. It can lead to complications like internal bleeding, kidney failure, and in severe cases, death.
Venomous Snake 3: Eastern Coral Snake
Characteristics and Identifiers
The Eastern Coral Snake, known scientifically as Micrurus fulvius, is one of the most visually distinctive snakes due to its bright coloration. The snake has a sequence of broad red and black rings separated by narrow yellow rings. Its slender body can reach lengths of up to 30 inches. This snake possesses a pair of small, fixed fangs in the front of its upper jaw, through which it delivers its venom.
Habitat in South Carolina
Eastern Coral Snakes inhabit the southeastern regions of South Carolina. These reclusive snakes prefer forested areas, scrub habitats, and are often found near water bodies. They are most active in the warmer months and are often hidden under leaf litter, logs, or burrows.
Potential Danger Level
Eastern Coral Snakes, while possessing potent neurotoxic venom, are shy and would prefer to flee than fight. They pose a threat to humans only when provoked or accidentally stepped on. A bite from an Eastern Coral Snake, while rare, can cause paralysis, respiratory failure, and, if not treated promptly, death.
Venomous Snake 4: Copperhead
Characteristics and Identifiers
The Copperhead, or Agkistrodon contortrix, is a medium-sized venomous snake known for its copper-red head. The body is usually a pale tan to pinkish-tan color and displays broad, dark crossbands that are shaped like an hourglass or dumbbell.
Habitat in South Carolina
Copperheads inhabit a range of habitats in South Carolina. They can be found in rocky-forested hillsides, hardwood and pine forests, and near streams or swampy regions. They are also commonly found in suburban areas and have adapted to living near human dwellings.
Potential Danger Level
Copperheads, while less aggressive than rattlesnakes, won’t hesitate to strike if they feel threatened. Although their venom is less potent compared to other venomous snakes in South Carolina, a bite can still cause severe pain, swelling, and in rare cases, more severe symptoms.
Venomous Snake 5: Cottonmouth (Water Moccasin)
Characteristics and Identifiers
The Cottonmouth, also known as Water Moccasin or Agkistrodon piscivorus, is a venomous snake easily identified by its dark, solid color and the characteristic white interior of its mouth. It is a relatively large snake, often measuring up to 48 inches long.
Habitat in South Carolina
Cottonmouths are semi-aquatic snakes and are commonly found around freshwater habitats. In South Carolina, they are often seen around swamps, marshes, ponds, and slow-moving streams. They are also known to inhabit lowland forests and floodplains.
Potential Danger Level
Cottonmouths are known to stand their ground when threatened, opening their mouth wide to display the white interior, hence the name. While they are not typically aggressive, they will bite if provoked. A Cottonmouth’s bite can be serious, causing intense pain and swelling, and medical attention should be sought immediately.
Venomous Snake 6: Pigmy Rattlesnake
Characteristics and Identifiers
The Pigmy Rattlesnake, or Sistrurus miliarius, is the smallest venomous snake in South Carolina, typically measuring between 12 to 24 inches in length. It is gray or tan with a series of dark, round spots down its back.
Habitat in South Carolina
The Pigmy Rattlesnake inhabits a variety of environments in South Carolina, including pine flatwoods, hydric hammocks, and sandhills. They often hide under logs, leaf litter, or burrows and come out to bask in the sun.
Potential Danger Level
While their small size might make them seem less threatening, Pigmy Rattlesnakes are known to be aggressive and won’t hesitate to strike when threatened. Their venom can cause pain, swelling, and bruising at the site of the bite, and medical attention should be sought immediately.
