Hairy crab is new ocean find

UK scientists have found an array of new species living around volcanic vents on the Southern Ocean floor south-east of South Georgia.

The haul includes a new type of yeti crab that researchers dubbed "The Hoff" crab when they first saw it, in honour of the famous American actor David Hasselhoff. The crab has long hairs - setae - on its ventral surface, or abdomen.

This video of the vents on the East Scotia Ridge was captured by the British deep-diving robot submersible, Isis.
