Deadly creature hidden at hotspot
Photographer Duncan Heuer has filmed a stunning video of a blue-ringed octopus at Sydney's Camp Cove beach.
Duncan Heuer came across the deadly creature hiding in the sand at the harbour-facing beach last Wednesday, with the deadly creature curling its tentacles "like a boxer".
Mr Heuer told Nine News that while he had hoped to photograph the creature he had been taken by surprise when he came across it.
"They're quite an exciting thing to find because they're very hard to spot," he said.
"I found a little sea spider on a rock that I was trying to photograph … While I was setting (my camera) up, this little octopus was on that rock as well, but I couldn't see it because it was camouflaged."
Mr Heuer said people might be surprised to find out how many blue-ringed octopuses were lurking around them.
"At night time, they're one of the prize things to see here in Sydney because they're actually a lot more common than people realise, but because of their cryptic nature they tend to hide away," he said.
Blue-ringed octopuses will only flash their striking colours when they are preparing to attack, according to the Australian Institute Of Marine Science.
Ranging in size from 12 to 20 centimetres, they will hide in rocks and crevices and usually only come out at night.
If stung a blue-ringed octopus' venom can prove deadly and will paralyse a person, causing them to lose the use of muscles but remain fully conscious.
Blue-ringed octopus victims will die because the paralysis causes a lack of oxygen, however, if a person is given CPR they are likely to survive.
In Australia there have only been two known deaths as the result of blue-ringed octopus bites.
