This large male, Jassa marmorata, is a tube building amphipod. It builds and lives in a tube of detritus and pieces of algae cemented together by its mucousy silk. Clive Brown's crab pot ropes in certain areas off Guernsey's south coast get coated by a thick layer of detritus and algae formed by this animal. This amphipod came up from a depth of about 50 metres and was photographed on 16 April 2003. Its identity was confirmed by Dr. Sammy De Grave from Oxford University's Museum of Natural History.
