A blue-ringed octopus has been pulled from the water of a popular beach on the Mornington Peninsula.
It was found at the Rye front beach foreshore amongst swimmers "in a very crowded area", according to local group Mornington Peninsula Incident Alert.
It’s a timely reminder for swimmers, surfers and beachgoers to keep an eye out for the octopus, which spans approximately 12-20cm when outstretched.
50-60 bright blue rings appear on their bodies when threatened, however they are naturally docile.
The most common cause of a blue-ringed bite is to children handling them.
A bite can cause paralysis or possible cardiac failure, however only two deaths have ever been recorded in Australia.
There's no known antidote.
