There's been a surge in blue-ringed octopus sightings at popular Adelaide beaches, with experts warning families to steer clear of the deadly animal.
A Surf Life Saving SA representative said that there had been over five reports of the highly venomous creature during the past three weeks, with the sea creature commonly found in rocks, rubble or other small hiding places.
Sightings have been spotted all the way down to Aldinga Beach, with most concentrated around Glenelg, Brighton and Somerton.
A coordinator from the Somerton Surf Life Saving Club youth coordinator Brad Keighran reported seeing 17 blue-ringed octopuses on a single day three weeks ago, accoridng to Adelaide Now.
A bite from a blue-ringed octopus can be painless, however the effects of the poison are fast-acting.
Within minutes, the victim will likely experience numbness and breathing difficulties, and if the bite is left untreated, it could be fatal.
