Description: Hermit crab searching for food in disturbed sediment. P. prideaux has a symbiotic relationship with the anemone Adamsia carciniopados, which it carries on its shell. The anemone offers protection while gaining food from the crab’s feeding. The anemone's tentacles can be seen in this video underneath the crab's shell. At Lancaster P. prideaux were found at a density of 0.11 individuals meter squared Item Type: Video Title: Hermit crab Copyright: SERPENT Project Species: Pagurus prideaux, Adamsia carciniopados Behaviour: feeding Site: Atlantic -- North Sea -- West of Shetland -- LancasterNorth Sea -- West of Shetland -- Lancaster Site Description: Seafloor Depth (m): 155 Latitude: 60 deg 11' 13" N Longitude: 3 deg 51' 18" W Countries: UK -- West of Shetland Habitat: benthic Rig: Byford Dolphin Project Partners: Hurricane Exploration (HEX), Senergy, Fugro ROV: Fugro Deposited By: Dr Andrew Gates Deposited On: 01 December 2009

Description: 12 tentacle anemone. The animal is Halcampa arctica (sometimes confused with/possibly synonymous with H. duodecimcirrata). It is not an Edwardsia—it’s a member of another family, Halcampidae. Both groups are burrowers, so this confusion is common. The identification in Jones and Gates 2010 is incorrect.

Description: Large anemone on rock, small orange cushion star, indeterminate yellow anemone (as above) and crinoids (likely Antedon sp.) on rock. The large anemone is a member of the Hormathiidae family, this is one of the two more diverse families in the deep sea and many of the taxa are distinguished based on internal anatomy (Such as how many pairs of mesenteries are complete or the size of nematocysts).
