1. What are the most common jellyfish in North Carolina?
If you spend time on the coast, you will most likely run into cannonball jellyfish, moon jellyfish, and Atlantic sea nettles. Cannonballs are dense and round, moons are translucent with four rings, and nettles have long, stinging tentacles. A few others like the mushroom jelly and lion's mane show up less often. Check the /animals/jellyfish page for a broader overview.

2. How can you tell a cannonball jellyfish from other types?
Cannonball jellyfish (Stomolophus meleagris) look like a firm, round dome that is usually whitish or brownish. They have no long tentacles hanging down, just a short frilly mouth. You will often see them washed up on beaches after storms. They are the least likely to sting you, but still handle them with care.

3. Where and when are moon jellyfish most likely to be seen?
Moon jellyfish (Aurelia aurita) are clear or bluish with four distinct horseshoe rings inside. They show up in calm inshore waters, especially in spring and summer. Look for them in sounds, marshes, and near inlets after a warm spell. They are very common around the Outer Banks from May through August.

4. When do sea nettles appear and where should you watch for them?
Atlantic sea nettles (Chrysaora quinquecirrha) arrive in late spring and peak in summer. They prefer the brackish water of the Pamlico and Albemarle Sounds. Their bell is whitish with reddish stripes and they have long, thin tentacles that can sting. If you see them, keep your distance.

5. What less common jellyfish species can you find offshore?
Beyond the big three you might spot lion's mane jellyfish (Cyanea capillata) with their mass of fine tentacles, or the mushroom jelly (Rhopilema verrilli) which looks like a flat, saucer-shaped cannonball. Portuguese man o' war (Physalia physalis) occasionally drift in from the Gulf Stream after strong winds. These are rare but get attention when they appear.
6. How can you identify a jellyfish from a safe distance?
Start with the shape: round dome vs. flat saucer vs. tall bell. Look at color and internal structures. Check for tentacles: few and short or many and long. Note the location: inshore vs. offshore. Use a stick or binoculars if you need a closer look. Never touch an unidentified jellyfish. For a quick reference, check the /wildlife/north-carolina page on local marine life.
