How dangerous is it to people?
Danger to people: PainfulIt can really hurt, but it is almost never serious.🚑 If it bites or stings
- Get out of the water and pick off any tentacles (with gloves or a cloth).
- For tropical box jellyfish: pour vinegar on the stings for at least 30 seconds, call for help and be ready to do CPR. For bluebottles and most others: rinse with seawater, then hot water for the pain.
Always call your emergency number first (112, 000, 911). This is general first aid guidance, not medical advice. First aid basics
⛑️ Stay safe
- Never touch, catch or tease a wild animal, even a small one, and even if it looks asleep or dead.
- Give it space. If you meet one, stay calm, step back slowly and let it go its own way.
- If one bites or stings you: stay calm, keep still, call your emergency number (112, 000, 911) or get to a hospital fast. Remember what it looked like, a photo helps.
It is not out to get you. It uses its venom to catch food or to protect itself, and it would much rather hide. More about staying safe
