Venomous snakes in South Carolina
VenomousEastern Diamondback Rattlesnake
Crotalus adamanteus
The largest venomous snake in North America and arguably the most dangerous. Its hemotoxic venom destroys tissue and blood cells, and a defensive bite is a medical emergency.
VenomousCottonmouth (Water Moccasin)
Agkistrodon piscivorus
A semi-aquatic pit viper named for the white interior of its mouth, which it gapes as a warning. The only venomous water snake in North America.
VenomousEastern Coral Snake
Micrurus fulvius
A relative of cobras with potent neurotoxic venom. Famous for the rhyme 'red touches yellow, kill a fellow' that separates it from harmless mimics.
VenomousPygmy Rattlesnake
Sistrurus miliarius
A small but venomous pit viper with a rattle so tiny it sounds like a buzzing insect. Bites are painful but rarely life-threatening due to the small venom yield.
Harmless snakes in South Carolina
Non-venomousCorn Snake
Pantherophis guttatus
A harmless, beneficial constrictor and one of the most popular pet snakes in the world. Frequently mistaken for the venomous copperhead.
Non-venomousEastern Ratsnake
Pantherophis alleghaniensis
A large, harmless constrictor and one of the best natural rodent controllers around homes and farms. Juveniles are gray and blotched, leading to copperhead confusion.
Non-venomousScarlet Kingsnake
Lampropeltis elapsoides
A harmless coral snake mimic. Its red bands touch black bands — 'red touches black, friend of Jack' — separating it from the venomous coral snake.
Mildly venomousEastern Hognose Snake
Heterodon platirhinos
A harmless toad-eater famous for its theatrics — it hisses, flattens its neck like a cobra, then flips over and plays dead. Rear-fanged with toxin that affects only amphibians.
Non-venomousEastern Ribbon Snake
Thamnophis saurita
A slender, harmless relative of the garter snake with crisp stripes and a notably long tail. Common around water but completely harmless.
Non-venomousBlack Racer
Coluber constrictor
A slender, fast, harmless snake that flees at high speed when disturbed. Often mistaken for something dangerous because of its dark color and nervous, alert behavior.
Non-venomousRough Green Snake
Opheodrys aestivus
A gentle, bright-green insect-eater that lives in bushes and is almost impossible to see against leaves. One of the most harmless snakes in North America.
Non-venomousEastern Kingsnake
Lampropeltis getula
A powerful, harmless constrictor famous for eating rattlesnakes and copperheads — it is immune to their venom. A homeowner's best natural defense against venomous snakes.
Non-venomousCoachwhip
Masticophis flagellum
One of the fastest snakes in North America, named for its braided whip-like tail. Harmless, but its speed and alertness startle people. The 'chases you' myth is just it fleeing.
