The Hidden Danger of the Summer Ocean: The Bell Jellyfish (Small-bladdered Jellyfish) — A Complete Guide to First Aid for Stings
They look as pretty as balloons, but touching them causes a pain like an electric shock—we’ve covered everything from what they are to first aid, and why you should never use vinegar.
The cone jellyfish (small-bladdered jellyfish) is a highly toxic creature that appears on Korean beaches during the summer; even dead specimens or detached tentacles retain their stinging ability. If stung: ① Get out of the water immediately → ② Rinse with seawater or saline solution → ③ Remove tentacles with a tool → ④ Apply cold or warm compresses; if systemic symptoms occur, call 119 immediately. Unlike other jellyfish, vinegar, tap water, and alcohol can spread the venom further, so they must never be used.
