Discover 38 Snakes Found In South Carolina (6 are Venomous!)

When you think of South Carolina you probably don’t think of snakes. But you should. South Carolina’s hot and humid climate combined with vast expanses of grasslands and the famous marshy wet landscape of the Low Country make it a haven for snakes of all kinds. This state has one of the largest varieties of native snakes with 38 different species of snakes that live there. South Carolina also has a lot of venomous snakes that you should know so that you will be able to identify them and keep yourself safe when you’re enjoying all that South Carolina has to offer.

Common Snakes In South Carolina

There are a lot of snakes in South Carolina. That can be a little intimidating to people who are afraid of snakes, but the snakes in South Carolina have an important purpose. They help control the state’s population of pests and insects and make it easier for farmers to protect their crops.

Let’s take a look at some of the more common non-venomous snakes that live in the Palmetto State. None of these snakes pose much harm and as you’re out and about you may see them across the state’s forests, grasslands, and lowland areas!

Corn Snake

Corn snakes live on the outer edges of forests and fields. They are large snakes that typically measure over four feet long. Corn snakes stand out because of their bright red-orange coloring and even if they’re hiding in the tall grass near the edge of a field you will easily be able to see them. These snakes are a type of rat snake (they’re sometimes called the red rat snake) and they feed on the rodents that like in the grass fields. Corn snakes also are great climbers so you should always look up when you’re walking along the edge of a South Carolina field that borders a forest because there may be a corn snake above your head as well as under your feet.

Black Racer Snake

Black racer snakes are among the most common snakes in South Carolina. They look a little scary because they are long and black, but they are harmless to people. They are also very fast and try to avoid people when possible. These snakes can move at speeds up to four miles per hour so chances are that if you see a Black Racer what you’re going to see is just the snake moving away from you at a high rate of speed. Black Racers are commonly seen on back roads and on walking paths around the state. If you do see one just stop for a minute and it will most likely flee.

Yellow Rat Snake

Yellow rat snakes are found only along the South Carolina coast. Like other types of rat snakes, they have a bad reputation but they are actually very beneficial to people because they kill the rodents and small mammals that eat and destroy crops. Yellow rat snakes have a brownish-yellow to golden-yellow color and have thin brown stripes. While rat snakes have been recorded growing as long as eight feet in length, they’re more commonly about four to six feet long.

Eastern Mud Snake

The Eastern mud snake is another snake that looks very scary but really is no threat to people. This non-venomous snake lives in the water and is primarily found along the coast or in the Low Country. Eastern Mud snakes are long. They can be up to a whopping 85 inches long. The snake’s primary color is glossy black and they have bright red markings.

Eastern Ribbon Snake

Eastern ribbon snakes are related to garter snakes. They are very common across South Carolina. Even though these snakes are tiny and are often a foot or less in length, they have a big attitude. An Eastern ribbon snake may bite you if try to handle it or if it feels threatened but they are non-venomous so even if they bite you they aren’t dangerous. However, if you do get bitten by an Eastern ribbon snake you still should get medical attention to prevent the bite from getting infected.

Water Snakes in South Carolina

There are five different species of water snakes in South Carolina. Water snakes belong to the genus Nerodia, and there are 10 different species of water snakes (9 true water snakes) across the United States. Water snakes are at ease in aquatic environments and rarely venture far from still sources of water like streams, lakes, and swamps. Let’s look at a couple of water snakes you might find in South Carolina.

Brown Water Snake

Brown water snakes are generally about 30 to 60 inches in length but can grow to a maximum of 60 inches. They range from Virginia down to Louisiana along the Atlantic and Gulf coasts. In South Carolina, they’re found inland into the Midland region but are not found upstate. Like other water snakes, the brown water snake feeds primarily on fish. When not in the water hunting, they’ll often climb trees or bask in the sun near water sources.

Florida Green Water Snake

Another largely aquatic snake that lives in South Carolina is the Florida green water snake. In South Carolina, green water snakes live exclusively in the Western and Southern regions of the state. These snakes generally range from 30 to 55 inches long and generally have either a red-brown body with black markings or an all-over dark olive-to-black body depending on what region they live in. Green water snakes can be aggressive and they do bite occasionally, but they are not venomous so they are not really dangerous. They can give you a nasty surprise though, so be careful when you are fishing, boating, kayaking, or doing other activities on the edges of marshes, ponds, and lakes.

Venomous (Poisonous) Snakes In South Carolina

South Carolina has six different types of venomous snakes which is a relatively high number of venomous snakes compared to other states. Some of the venomous snakes in South Carolina are:

Copperhead

Copperheads are the most common venomous snake in South Carolina. They can be found all over the state so you should have your guard up whenever you hiking, biking, or engaging in outdoor activities in South Carolina. Copperhead snakes are only usually two to three feet long but they are very heavy and wide. Their colors vary based on the habitat they are in but they are usually orange, brown, or even pinkish-red with brown wide markings. While not aggressive by nature, the copperhead is responsible for more bits than any other venomous snake in the United States. Thankfully, the fatality rate of their bites is just .01%. If bit by a copperhead, make sure to seek medical attention. Most people bitten by these snakes are back to normal within 2 to 4 weeks.

Eastern Coral Snake

Eastern coral snakes live primarily in the sandy soil common along the South Carolina coast and in the Low Country area. Coral snakes have a particularly bright coloring that is a thick red stripe banded by thin stripes of yellow or white. Even though Coral snakes are venomous and you should never handle one in the wild they rarely are seen above ground so they are not a huge threat. These bright snakes prefer to stay buried in the sandy soil whenever possible. There has been just one death from a coral snake bite since the 1960s. It came from a Florida man who didn’t seek medical attention after getting bit.

Eastern Diamondback Rattlesnake

Eastern diamondback rattlesnakes in South Carolina prefer to be on the coast where there are lots of sand dunes and plenty of sandy soil. Diamondback rattlesnakes are the largest venomous snakes in South Carolina. Some of them weigh in at more than ten pounds and stretch almost six feet. Exceptional eastern diamondbacks have been measured at up to 7 feet 10 inches, but diamondbacks over seven feet in length are rare. The Eastern diamondback rattlesnake isn’t a common sight in South Carolina, but if you’re having a beach day or spending time along the coast it’s smart to keep an eye out for these snakes.

Cottonmouth Snake

Another venomous snake that prefers to live in the coastal area and among the sand hills in South Carolina is the cottonmouth snake. Cottonmouth snakes are easy to identify because they have a white patch underneath and inside of their mouths. They are also sometimes called water moccasins. Their coloring varies based on where they are. Cottonmouths can have a dark coloring with gray markings, or a dark coloring with reddish-brown markings, but their base color is almost always dark. Cottonmouths are at ease in the water and are mostly found near freshwater sources.
