Venom comes out through its fangs or teeth when it bites.

How dangerous is it to people?

Danger to people: SeriousA bite or sting needs a doctor. Deaths are very rare.

๐Ÿš‘ If it bites or stings

  • Pressure immobilisation: wrap a firm elastic bandage over the bite and then up the whole limb, splint it, and keep the person completely still until help arrives.
  • Get the person out of the water and to a hospital fast.

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
