Here Are Six Deadly Snakes Commonly Found In South Carolina You’ll Want To Avoid

Most people stick to the old rule of the triangular-shaped head as an easy marker for identifying venomous snakes, but as you'll see in this list, it's not a sure bet. One of the six poisonous snakes found in South Carolina doesn't have a triangular-shaped head. Read on to learn more and familiarize yourself with this list so you'll know precisely what kind of snake you've encountered.

According to the South Carolina Department of Natural Resources, the most common venomous snake found in South Carolina is the copperhead. Adults can grow up to four feet in length. These snakes are easily identifiable by the hourglass shape that is found on their back. Although a bite from a copperhead is usually not fatal, the venom is poisonous. The mouth and snout of the copperhead is distinct in helping to distinguish it from its close cousin, the cottonmouth. Copperheads have a sloping jawline under the snout.

The coral snake is found in South Carolina with three differing color variations. But the one that's venomous is shown here with the biggest distinction among the three: the black and red bands never touch. Additionally, the venomous version of the coral snake always has a black nose. While the copperhead above is commonly reported throughout the Palmetto State, the coral snake is much more secretive and spends much of its time in hiding or even underground. Adults grow to an average of two feet.

If you spend any amount of time in or near fresh water sources in South Carolina, then you'll want to be able to immediately identify this poisonous snake commonly found in the wetlands and swamps in our state. Although the snake is known to only strike when it feels it has no other choice, the cottonmouth doesn't hesitate to stand its ground and strike a gaping, open-mouth pose to make an impression. Cottonmouths have a wide girth and grow to a full three or four feet in adulthood.

The largest venomous snake in South Carolina is seen mostly in longleaf pine flatwoods, rolling pine hills, and in the grasslands of the lower coastal region of the state. Eastern Diamondback Rattlesnakes are predatory and lay in wait for their prey to cross their path before striking. As its name suggests, this venomous snake gets it name from the dark brown diamond pattern that runs down its back. Eastern Diamondbacks give birth during the late summer to early fall, so be extra vigilant if hiking in the fall in South Carolina.

South Carolina's timber rattlesnakes take on two varieties. The one commonly found in the mountains is known to inhabit south-facing rock outcroppings in the cooler months and spends its time in nearby areas around streams and ponds during warmer months. The piedmont and coastal species of the timber rattlesnake is called the canebrake rattler. Seen here, it loves to inhabit wetland areas and forested settings. Both of these snakes grow to an adult length of three to five feet.

The smallest of the rattlesnakes found in South Carolina, the pigmy rarely grows more than a foot or so in length. It's found throughout the state with the exception of the mountains. If you're anywhere near fresh water, such as ponds, swamps, or marshes, then it's possible to encounter a pigmy snake. It's unusual markings include a gray or pinkish background color with pink or black spots. It also sometimes has a pink line that runs down its spine.
