South Carolina's coastal waters host a few octopus species, most commonly the Atlantic pygmy octopus and the common octopus. This guide covers the types you are most likely to encounter, how to tell them apart, and where to look for them along the coast.
What are the most common octopus species in South Carolina?
The two species you will most likely come across are the Atlantic pygmy octopus (Octopus joubini) and the common octopus (Octopus vulgaris). The Atlantic pygmy is small (under 12 inches) and often found in shallow sandy bottoms near jetties and grass flats. The common octopus is larger and more widespread, usually in rocky reefs and offshore wrecks. A third species, the Caribbean reef octopus, may occasionally stray into warm Gulf Stream waters but is rare this far north.
How can you tell the main types apart without overcomplicating it?
Size is your quickest clue. Atlantic pygmy octopuses stay small with a mantle length under 2 inches, while common octopuses grow much larger (mantle up to 10 inches). Color patterns also help: pygmy octopuses are usually pale brown or tan with small white spots, whereas common octopuses can shift from gray to reddish brown and often have a rough, warty skin texture. Look for the circular, smooth skin of the pygmy versus the bumpy texture of the common.
Where and when is each type most likely to be noticed?
Atlantic pygmy octopuses are best found in summer and fall in shallow waters less than 30 feet deep, especially around Murrells Inlet, Beaufort, and the tides of the ACE Basin. Common octopuses prefer deeper structures like the artificial reefs off Charleston and the wrecks near Hilton Head. They are active year-round but more frequently seen in fall when water temperatures are mild. Start your search in hard-bottom areas or around crab pots, as octopuses often hide inside old shells.
What should you know about octopus behavior for successful spotting?
Octopuses are mostly nocturnal, so early morning or late evening dives increase your odds. They are masters of camouflage, so look for movement or a sudden shift in color. During low tide, check tide pools and abandoned burrows. If you see a small pile of shells (a midden), an octopus is likely nearby. Always respect their space and avoid touching, as they can bite and have a sharp beak.

How do South Carolina's octopus sightings compare to other wildlife?
While octopuses are not as commonly seen asbald eaglesor herons, they offer a unique reward for patient observers. TheSouth Carolina wildlifescene is rich, but octopus spotting requires a bit more planning and a willingness to get in the water.

Are there any rare octopus species in South Carolina waters?
The Caribbean reef octopus (Octopus briareus) is occasionally reported off the coast, especially after strong Gulf Stream eddies push warm water north. It is more colorful with blue-green spots and a distinct yellow stripe on the arms. Sightings are rare and not something to rely on, but if you are diving deep offshore in late summer, keep an eye out. Theoctopus types pagehas more details on identification.
