''Didemnum'' is a genus of tunicates in the family Didemnidae. Some species of ''Didemnum'' can be characterized as invasive species. This is particularly an issue off the east coast of the United States, where in early 2006, ''Didemnum'' were estimated to inhabit more than 175 square kilometers of this undersea region. Other areas where ''Didemnum'' are seen as invasive include Canada, New Zealand and the Netherlands.〔"Invasion der Pfankuchen" Der Spiegel, 1/2006, p. 102〕 ''Didemnum vexillum'' turned up on coast of state of Washington in 2009 and has been showing up in Coos Bay and Winchester Bay, Oregon as of 13 May 2010.〔http://www.oregonlive.com/environment/index.ssf/2010/05/fast-growing_invasive_species.html〕 ==Species== * ''Didemnum albidum'' (Verrill, 1871) * ''Didemnum amethysteum'' (Van Name, 1902) * ''Didemnum asperum'' (Milne-Edwards, 1841) * ''Didemnum biglans'' (Sluiter, 1906) * ''Didemnum candidum'' (Savigny, 1816) * ''Didemnum carnulentum'' (Ritter and Forsyth, 1917) * ''Didemnum chilense'' (Arnbaeck, 1929) * ''Didemnum coriaceum'' (Von Drasche, 1883) * ''Didemnum fulgens'' (Milne-Edwards, 1841) * ''Didemnum galacteum'' (Lotufo and Dias, 2007 * ''Didemnum gelatinosum'' * ''Didemnum helgolandicum'' * ''Didemnum lahillei'' (Hartmeyer, 1909) * ''Didemnum maculosum'' (Milne-Edwards, 1841) * ''Didemnum molle'' (Herdmann, 1886) * ''Didemnum proliferum (Kott, 1981)'' * ''Didemnum santaelenae'' (Van Name, 1945) * ''Didemnum studeri'' (Hartmeyer, 1911) * ''Didemnum tenue'' (Herdmann, 1886) * ''Didemnum vanderhorsti'' (Van Name, 1924) * ''Didemnum vexillum'' (Kott, 2002) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Didemnum」の詳細全文を読む スポンサード リンク
