Surf lifesavers have warned kids to beware deadly marine animals hiding in seashells after a girl unknowingly took home a blue ringed octopus.
After a day of playing on Coogee beach, south of Perth, Western Australia, the girl collected some shells to take home.
As her aunt was washing them she discovered a small blue ringed octopus was hiding in one of the shells.
Coogee Beach WA Surf Life Saving Club uploaded photos of the dangerous creature to social media platform Facebook as a warning to help keep kids safe at the beach.
“A young girl was at the beach this morning in front of our club building sandcastles and collecting shells,” the post read.
“Lucky her Aunty was cleaning the stash* of shells when they got home as this critter* emerged.
“They look beautiful … but a bite can be deadly.”
There are several blue ringed octopus species. They are highly venomous* and are usually found in rock pools and coral reefs right around the Australian coast.
They can change shape to wriggle into gaps between or cracks in rocks.
The octopus gets its name for its circular, iridescent* blue markings, which are usually only displayed when the animal feels threatened and is about to release its poison.
If the octopus is relaxed, it is a beige or pale brown colour.
Full-size octopuses are about as big as an adult’s hand, but they can be as small as a fingernail when they are younger.
For your safety and the safety of marine creatures, don’t touch any marine creatures!
To avoid being bitten by an octopus that’s hidden, don’t poke your hand or foot into rock pools, cracks in rocks and don’t poke your fingers into sea shells.
According to the Australian Institute of Marine Science, the chemical the octopus releases, which is called tetrodotoxin, aims to paralyse* its target.
Though they are very common on Australian beaches, only two people are known to have died from their bite, one in 1954 in Darwin and the other in 1967 in Sydney.
A blue ringed octopus bite may not hurt, though there may be a spot of blood. As the toxin* spreads through the body, the lips and tongue may feel numb, then breathing could become difficult.
WHAT TO DO IF BITTEN
- Tell an adult
- Call 000 (triple zero) immediately
- Press on the bite area or wrap a bandage or clothing firmly around the bite area. This is called a compression bandage.
- Proceed with CPR* if necessary
