Are There Crocodiles in South Carolina?

South Carolina is home to a robust population of American Alligators (Alligator mississippiensis), the state’s sole native crocodilian species. These reptiles are a common and integral part of South Carolina’s aquatic ecosystems.

Alligators in South Carolina

American Alligators are widely distributed throughout South Carolina, particularly in the coastal plain and Lowcountry regions. Their preferred habitats include freshwater lakes, rivers, swamps, and marshes, though they are also found in farm ponds, abandoned rice fields, and coastal impoundments. While primarily freshwater animals, alligators can venture into brackish waters.

South Carolina’s warm, humid climate and extensive wetlands provide an ideal environment, supporting an estimated population of over 100,000 alligators. Major rivers like the Savannah, Pee Dee, Edisto, Waccamaw, Santee, and Congaree, along with Lake Marion, host significant populations. Alligators are active year-round, with increased activity from April to July during their mating and nesting season.

Distinguishing Alligators From Crocodiles

Distinguishing alligators from crocodiles involves recognizing specific features. Alligators have a broad, rounded, U-shaped snout, suited for crushing hard-shelled prey. Crocodiles, in contrast, possess a narrower, pointed, V-shaped snout, adapted for catching fish. A key distinction is teeth visibility: an alligator’s lower teeth are hidden when its mouth is closed, fitting into internal sockets. For crocodiles, some lower teeth, especially the large fourth tooth, remain visible and interlock with the upper teeth even when the mouth is closed.

Alligators also have darker, blackish-gray skin, while crocodiles typically exhibit lighter, olive or tan hues. While alligators primarily inhabit freshwater, crocodiles are more tolerant of saltwater and can be found in coastal, brackish, and marine habitats.

Coexisting with Alligators

Living safely alongside alligators requires awareness and adherence to safety guidelines. Maintain a safe distance, staying at least 10 feet from water edges and 60 feet from an adult alligator. Approaching, feeding, or harassing alligators is illegal in South Carolina and can cause them to lose their natural fear of humans, leading to dangerous encounters. Fed alligators may associate people with food and become aggressive, often necessitating their removal, which typically results in the animal being killed.

Supervise children and pets closely near water bodies, as they can be mistaken for prey. Keep pets on leashes near water. Limit swimming to designated areas and avoid dawn, dusk, or night, when alligators are more active and hunt. If an alligator approaches on land, back away slowly and make loud noises to deter it.

Alligators are generally not aggressive towards humans, and unprovoked attacks are rare. If an attack occurs, fight back by targeting the alligator’s eyes or snout and preventing it from pulling you into the water. Report nuisance alligators or those exhibiting aggressive behavior to the South Carolina Department of Natural Resources (SCDNR) for public safety and management.
