A woman has issued a warning after making a “deadly” find on a beach in Sydney’s south.
She posted a video to Facebook holding a shell at Kurnell on Saturday.
“Please be careful at Kurnell,” she wrote.
Sand, dirt and water is seen in the shell but soon it becomes clear.
Lurking in the shell is a small blue-lined octopus, which is a type of blue-ringed octopus.
The deadly venom of a blue-ringed octopus
According to The Australian Museum, the species uses “an extremely powerful venom” to kill its prey including crabs and small fish.
The octopus can also use this venom, known as tetrodotoxin, on humans too which can cause paralysis and death.
On Facebook, people marvelled at the tiny octopus.
“Cute but deadly,” one woman wrote.
Others remarked they had “never seen them that small before”.
“Great to show people as they might not think they are dangerous,” another woman wrote.
She is right too – some people do not realise how deadly blue-ringed octopuses can be.
