How to Identify a Jellyfish
Three quick steps to an instant, AI-powered identification.
Photograph the whole animal — the bell and any tentacles — from above or the side. Even a stranded specimen on sand works.
Our AI reads the bell shape, color, size, and tentacle arrangement, comparing them against a broad range of jellyfish and jelly-like animals.
Receive the likely species, its range and habitat, and whether it's a harmless drifter or a stinger to keep well clear of.
Other Ways to Identify a Jellyfish
Local Beach Advisories
Lifeguards and beach-safety pages often post which jellyfish are active locally and how dangerous they are that season.
Marine Field Guides
Coastal wildlife guides picture regional jellies by shape and color, useful once you've narrowed the options.
Aquariums & Marine Labs
Public aquariums and marine biology departments can confirm unusual or dangerous species from clear photos.
Photo Quality
- ✓Capture the whole bell shape from above if you can.
- ✓Show the tentacles and their length and arrangement.
- ✓Photograph in even light without heavy glare on the water.
- ✓Include a scale reference for the bell's diameter.
Best Practices
- •Never touch a jellyfish to pose it — many sting even when stranded or dead.
- •Shoot from a safe distance and angle rather than handling it.
- •Note the location and water conditions where you found it.
- •Take a couple of angles if the body is transparent.
