Diphyidae
The Diphyidae are a family of siphonophores. These are colonial siphonophores with two nectophores (swimming bells) arranged one behind the other. The front one includes a somatocyst (extension of the gastrovascular system), while the hind one does not. The somatocyst often contains an oil droplet for buoyancy control. A nectosac (central cavity with muscular walls) in each nectophore allows the organism to swim efficiently. Systematics The World Register of Marine Species includes the following taxa in the family Diphyidae: *Subfamily Diphyinae Quoy & Gaimard, 1827 ** Genus '' Chelophyes'' Totton, 1932 *** ''Chelophyes appendiculata'' (Eschscholtz, 1829) *** ''Chelophyes contorta'' (Lens & van Riemsdijk, 1908) ** Genus '' Dimophyes'' Moser, 1925 *** ''Dimophyes arctica'' (Chun, 1897) ** Genus '' Diphyes'' Cuvier, 1817 *** ''Diphyes antarctica'' Moser, 1925 *** ''Diphyes bojani'' (Eschscholtz, 1825) *** ''Diphyes chamissonis'' Huxley, 1859 *** ''Diphyes dispar'' Chamisso & Ey ...
