It would be enough salt and pepper squid to feed an army as a genuine monster of the deep is found at Jervis Bay.

Hold on to your rods, a twelve foot giant squid has been spotted off the coast at Jervis Bay on the NSW South Coast.

Although it was found dead, it's proof this incredible creature lives in our part of the world.

Al McGlashan is the author of The Fishing Bible and is a fishing writer with The Daily Telegraph - he's also the man who can lay claim to making this awesome sighting.

He says it's the first time he's seen this brightly coloured creature up close and completely in-tact.

"In all my time of fishing, I've never seen calamari rings so big," he said.

"It was massive."

Al says he has always wanted to see a giant squid as they are usually rare.

"They're sort of one of those mythical things.

"You hear those stories about ancient mariners getting attacked in their boat and you only hear about the very occasional one being washed up down in Tassie."

Al spotted the monstrous creature during a tuna fishing expedition 50 kilometres off the coast of Jervis Bay.

It's uncertain how the squid died and due to its weight, Al was unable to haul the squid into his boat for an autopsy.
