The cephalopods are a class of molluscs. Members include octopuses, squids, cuttlefish, nautiluses and the fossil ammonites. They are characterised by a ring of tentacles around their mouth, and swim using a form of jet propulsion by squirting water out of their body. All cephalopods are carnivorous.
Scientific name: Cephalopoda
A recently discovered octopus and a bioluminescent vampire of the deep.
The unique behaviour of the dumbo octopus was captured with the help of MBARI's underwater marine researchers and innovative film technology, developed with NHK in Japan. Even standard HD cameras can't operate in such low light conditions, but the New Super-HARP (High-gain Avalanche Rushing amorphous Photoconductor) equipment is ultra sensitive and particularly effective with slow-moving images.
