Description: This hydromedusa is probably Benthocodon (perhaps B. pedunculata). However, the genus may be Voragonema. Without a higher resolution image or a properly preserved specimen, it is impossible to be certain. These are common in the benthic boundary zone in all the oceans. They apparently feed on copepods, perhaps too, the organic fluff that carpets the sea floor. Item Type: Image Title: Benthocodon sp. Copyright: SERPENT Species: Benthocodon sp. Behaviour: These animals drift slowly over the surface of the sediment apparently feeding on copepods and organic material on the sediment Site: Indian -- Indian Ocean -- East Africa -- Zafarani Depth (m): 2601 Countries: East Africa -- Tanzania Habitat: Benthic boundary zone Rig: Ocean Rig Poseidon Project Partners: Statoil, Oceaneering ROV: Millenium 93 and 73 Deposited By: Dr Andrew Gates Deposited On: 19 April 2012

Aequorea showing distribution of bioluminscence around the edge of the bellTo obtain this photo, Dr. Ward "flash froze" the specimen on a ceramic tile that had been painted black and stored in a -80 C freezer, then took a series of photographs as it thawed (freezing and thawing stimulates bioluminescence in these animals). The image was captured with a Nikon 35 mm SLR camera mounted on a tripod. Note that Aequorea bioluminescence appears only around its perimeter; light seen elsewhere on the body in photos is generally reflection from photographic flashes or sunlight.
