Deep under the Antarctic ice, a rare colourful burst of starfish and 3m-long monster worms has been filmed by a BBC camera crew.
The extraordinary swarm of deep-sea creatures gathered to feed on the body of a dead seal, which had sunk to the ocean floor.
Such a bounty of food may only occur one every ten years in the ice-cold waters of McMurdo Sound, Antarctica.
The time-lapse images were taken by divers filming for 'The Deep' episode of the BBC natural history series
which will be broadcast at 2100GMT on BBC One on Monday 30 November.
