6 Types of Jellyfishes in South Carolina

1. What are the most common jellyfish types on the South Carolina coast?

The three jellyfish you are most likely to see from Myrtle Beach down to Hilton Head are the **moon jelly** (Aurelia aurita), the **Atlantic sea nettle** (Chrysaora quinquecirrha), and the **cannonball jellyfish** (Stomolophus meleagris). Moon jellies have a translucent, saucer-shaped bell with four horseshoe-shaped rings. Sea nettles have a reddish or brown bell with long, lacy tentacles. Cannonballs have a firm, dome-shaped bell with no long tentacles. Learn more about their biology on our/animals/jellyfishpage.

In South Carolina, jellyfish sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.

2. How can you tell a moon jelly from a sea nettle?

The easiest way to separate them is by color and tentacle structure. Moon jellies are nearly clear with a faint blue or pink tint and have short, fine tentacles around the rim. Sea nettles are darker, often brown or reddish, and their tentacles are long, thin, and stream behind them in the water. Cannonball jellies are easier: they look like a solid white or yellowish dome with no visible tentacles underneath. For a quick field reference, see the/wildlife/south-carolina/jellyfish/typesguide.

3. Where and when are you most likely to see each type?

Moon jellies appear year-round but peak in late spring and early fall in calm inlets and estuaries. Atlantic sea nettles show up in summer, especially around the mouths of rivers and salt marshes. Cannonball jellies wash onto beaches after strong onshore winds or storms in late summer. For the best odds, check local tide charts and avoid post-storm swimming. Coastal spots like Folly Beach and Hunting Island often have jellyfish reports. For more state-specific wildlife info, visit our/wildlife/south-carolinahub.

5. Are there venomous jellyfish in South Carolina?

The Atlantic sea nettle can deliver a sting that causes a burning rash, but it is rarely dangerous. The Portuguese man o' war (Physalia physalis) occasionally drifts into SC waters and has a much more severe sting, though it is not a true jellyfish. The moon jelly and cannonball jellyfish have very mild stings that most people barely notice. Always rinse with vinegar if stung and avoid rubbing the area.

6. Which jellyfish species chart tees help you remember these differences?

7. What are some common questions about jellyfish in South Carolina?

**Q: When is jellyfish season in South Carolina?** Jellyfish are present year-round, but the highest concentrations occur from May through October, especially for sea nettles.

**Q: Can you eat cannonball jellyfish?** Yes, cannonball jellies are harvested and exported for food. They are safe to handle but may cause mild skin irritation.

**Q: What should I do if I see a dead jellyfish on the beach?** Avoid touching it. Even dead tentacles can still sting. Leave it for the tide to carry away.

**Q: Are there box jellyfish in South Carolina?** No, box jellyfish (class Cubozoa) are rarely found in the Atlantic north of Florida. Stings from local species are generally not life-threatening.
