World's first six-legged octopus discovered

(CNN) -- English marine experts have laid their hands on an octopus that's missing two of its own: a six-limbed creature that they have dubbed 'hexapus.'

Ordinarily, octopodes have eight arms and legs. And should they lose one or more in an accident, they can grow the limbs back.

Which is what makes 'Henry' -- as staffers at Blackpool Sea Life Centre in northwest England have dubbed their find -- so unique.
His missing limbs stem from a birth defect.

"If you look closer between the legs, there's webbing that attaches each of the arms together," John Filmer of the Sea Life Centre told CNN Tuesday. "You'd assume if he'd lost one of his legs in an accident, there would be space for an arm to grow back.

"But there's no space for two extra legs to grow back. That's just how he is."
Staffers called others zoos and aquariums and scoured the Internet to see if there were records of similar creatures.

"No one has ever heard of another case of a six-legged octopus," said display superviser Carey Duckhouse.

Until Henry, the most famous six-legged octopus was one that appeared in a 1955 B-movie, 'It Came From Beneath The Sea.'
As was common of many science fiction movies of the era, the film was made on a shoestring budget -- and designers left off two legs from the creature because of budget contraints.
