A woman has been bitten by a deadly blue-ringed octopus at a popular beach in Sydney.
The woman, in her 30s, was bitten on the stomach at Chinaman’s Beach in Mosman at about 2.45pm today.
A blue-ringed octopus bite has venom strong enough to kill over 20 humans despite the sea creature being small and usually measuring around 8cm in length.
The venom, called tetrodotoxin, induces paralysis, slowing down the body to a point at which they will not be able to breathe and not get enough oxygen.
There is no antivenom for tetrodotoxin, with victims of a bite only able to outlast the toxin on a ventilator until its effects subside.
While there is a serious danger, there have only been a handful of confirmed casualties from a blue-ringed bite as the creatures are more likely to hide in small crevices instead of attack.
