We've all heard of octopuses, but how about a hexapus?
That's what zookeepers at the Blackpool Sea Life Centre in northern England call their six-legged octopus, who was fished out of the Irish Sea off Wales last month.
Henry the Hexapus, as he's been dubbed, came about his reduced status as a result of a birth defect, not injury as is common among octopuses, squid and their cuttlefish cousins.
"We've scoured the Internet and talked to lots of other aquariums and no one has ever heard of another case of a six-legged octopus," supervisor Carey Duckhouse told Agence France-Presse.
Henry's unusual configuration wasn't noticed until a few days ago, when the hexagonal mollusk finally attached himself to the glass wall of his tank, astonishing staffers.
He'll be going on display soon as part of a larger octopus exhibit entitled "Suckers," according to the Times of London.
