Blue-ringed octopus

A blue-ringed octopus bite can be fatal. They live in beach rock pools and only show their blue markings if you disturb them.

Have I been bitten?

The blue-ringed octopus can bite you if you touch or stand on it. Their bite is often painless but if you’ve been bitten, you may:

  • feel numb around your mouth, tongue, face and neck
  • have a tight chest and difficulty breathing.

How to treat bites

Call Triple Zero (000), their bites can be fatal. What you do next depends on where the bite is.

Leg bites

Call Triple Zero (000) and apply a bandage and splint. Make sure the bandage is comfortable, as it will need to be worn until a doctor removes it. Apply the bandage even if the person is already ill from the poison.

Keep the person’s whole body still and don’t remove their clothing. Moving them may cause more venom to enter the blood stream.

Apply the bandage and splint

Apply a broad pressure bandage over the bite site as soon as you can. Crepe bandages are best, but you can use any flexible material. For example, clothing or towels.
