Visitors to Edisto Island and the snakes in the area have one thing in common: They both love the warm weather.
While there is no reason to fear the venomous snakes in the area, it is important to know about them to avoid any unnecessary fear. In this two-part series on snakes, find out everything you would ever want to know about Edisto’s most slithery residents.
We’ll begin with the venomous snakes of South Carolina: The Copperhead, Cottonmouth, and Rattlesnake.
The Copperhead
The copperhead snake, which is also known as the highland or water moccasin, is the most common venomous snake in the eastern United States and South Carolina.
Copperheads are a patterned and colorful snake that can be more than three feet long. They have copper coloring on their heads and pinkish underbellies. Another identifying characteristic is the dark bands or hourglass patterns on the backsides of the snake. Infant copperheads are distinguishable by the bright yellow coloration on their tails.
Like humans, copperheads enjoy living by the water, so they are most commonly found by bodies of water like streams, swamps, and rivers, but not on the beach. They also live on the land, but prefer to be in undeveloped areas like the dense forests all over the lowcountry. That said, these snakes are not just hanging out waiting to scare a human that might be passing by. They do not like to be around possible threats, so areas where there is heavy human foot traffic are typically devoid of snakes. After all, humans are much bigger than snakes and we actually scare them.
All copperheads actually care about is eating the abundant rodents, birds, lizards, smaller snakes, and various critters in the area. They don’t want anything to do with humans or our pets, but they will defend themselves if provoked. That is why it is important to never touch a copperhead or harass it in any way. They will bite as a final line of defense in a battle against a human or other threat.
The venom of a copperhead is the least venomous of the snakes in the area, but they are responsible for the most bites in all of the eastern United States. If you or your pet is bitten by a copperhead, seek medical attention immediately, but try to remain calm.
It’s important to realize that the venom in a copperhead snake is actually beneficial to humans. A protein in the venom is known to prevent cancer cells from spreading and is particularly beneficial in the treatment of ovarian and breast cancers.
The Cottonmouth
The cottonmouth snake is one of the scariest snakes in the area because of their dramatic presentation when provoked. A threatened cottonmouth opens its mouth to show its fangs and white lining, which resembles cotton. This is a last warning before it strikes, so it is important to get away from a cottonmouth when it is striking this pose.
When the cottonmouth is not in attack-mode, it can be identified by dark black or brown body with slightly lighter bands. They can be four feet long and have a thick body. Cottonmouths stick to the wetlands and hide out in the murky swamps and rivers of the lowcountry. They are most active at night, but can be found in the daytime.
Cottonmouths are often thought of as highly aggressive, but in actuality, they are more docile than other venomous snakes. However, while not generally a threat to humans, especially not in the Edisto area, a bite from a cottonmouth is serious. Thankfully, antivenins are available to treat anyone who is bitten by a cottonmouth.
The Rattlesnake
The Eastern Diamondback Rattlesnake is the largest species of rattlesnake in the area. These snakes can be up to 10 lbs and over five feet long. They have a distinct white diamond pattern covering their bodies which range in color from brown, tan, or yellow. In addition, they have the unmistakable rattle on their tail ends.
Unlike the copperhead and cottonmouth snakes, these snakes prefer to live in dry areas. They make their homes in dry sandy areas, pinewoods, hardwood hammocks, and sometimes on the banks of a river or creek even though they do not like to get wet. That said, these snakes will swim in order to get from one barrier island to the next while on a search for food.
These snakes also differ from the copperhead and cottonmouth in that they are slow moving and spend much of their time coiled and lying in scrub bush, in pine needles in the forest, or in palm fronds in sandy areas (undisturbed areas, not the heavily traveled beach). They eat rats, mice, squirrels, and other small rodents.
Diamondbacks do not typically bother a human unless a human bothers it. They have the ability to rise up a third of its own body length to strike. A strike from a rattlesnake is very painful and causes intense tissue damage. Their venom is highly toxic, but antivenin is readily available in all areas where these snakes are plentiful. It’s also of note that the venom from diamondbacks is used medicinally as a treatment for strokes and blood clots.
While each of these snakes does make the lowcountry its home, they should not be feared. It is a safe bet that most people who visit Edisto or live here will never see any of these snakes let alone have to worry about them. It’s also important to remember that all snakes are important to the ecosystem of Edisto Island.
