Henry the Hexapus is a six-limbed octopus found by British marine scientists in 2008.[1][2] The name alludes to King Henry VIII, who had six wives.[3]
Henry was found off the coast of North Wales in a lobster pot, and is in captivity at the Blackpool Sea Life Centre in North West England. Henry's unusual number of arms was not immediately noticed, and appear to have resulted from a natal anomaly, rather than a physical accident.[1][2] Developmental biologist PZ Myers calls the defect "an ordinary sort of error."[4] After being taken from the sea, he was transferred to the Anglesey Sea Zoo, which, in turn, donated him to the Blackpool Centre.[2]
Henry is going to be in a new exhibit with an octopus at the Blackpool Sea Life Centre, entitled "Suckers".[2] An aquarium spokeswoman has stated that "[Henry]'s a lovely little thing."[1]
Many other octopus arm anomalies have been recorded in the past,[5][6] including a 10-armed Octopus briareus,[7] one with a forked arm tip,[8] an octopus with double hectocotylization,[9] and specimens with up to 96 tentacle branches.[10][11][12]
