Species status (?) | Non-indigenous species References (not structured): Berrill NJ (1931) Studies in tunicate development. Part II. Abbreviation of development in the Molgulidae. Philosophical Transactions of the Royal Society of London 219B: 281-346. Arenas FF, Bishop JDD, Carlton JT, Dyrynda PJ, Farnham WF, Gonzalez DJ, Jacobs MW, Lambert C, Lambert G, Nielsen SE, Pederson JA, Porter JS, Ward S, Wood CA (2006) Alien species and other notable records from a rapid assessment survey of marinas on the south coast of England. Journal of the Marine Biological Association of the United Kingdom 86: 1329–1337. Comments: Records of Molgula manhattensis from the island of Ireland have not yet been confirmed, despite accounts that refer to it being found there (Holmes and Gotto, 2000). Both M. socialis and M. tubifera have similarities with M. manhattensis. Berrill (1931) considered M. manhattensis to occur in Britain, but stated it to be a synonym of M. tubifera, whereas Hayward and Ryland (1995) believe that these species are distinct. One of the more recent surveys on the south coast of Britain (Arenas et al., 2006) failed to find this species, recording only M. socialis, presumed to be a native species. As there is much confusion over these closely related species, some genetic studies may aid in resolving these difficulties. |
