How dangerous is it to people?

Danger to people: Very dangerousIt can kill a person who gets no treatment.

๐Ÿš‘ If it bites or stings

  • Put the wound in hot water, as hot as the person can stand without burning (test it with your own hand), for 30 to 90 minutes. Get medical help, especially for stonefish and stingrays.

Always call your emergency number first (112, 000, 911). This is general first aid guidance, not medical advice. First aid basics

โ›‘๏ธ 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
