''Inia'' is a genus of river dolphins from South America. It contains one to three species. ==Taxonomy== The genus was described by Alcide d'Orbigny in 1834 when ''Delphinus geoffrensis'', described by Henri Marie Ducrotay de Blainville in 1817, was recognized to be a unique taxon. A 1998 classification listed a single species, ''Inia geoffrensis'', in the genus ''Inia'', with three recognized subspecies. Most of the scientific community accepted this single species classification, as did the IUCN. In 2012 the Society for Marine Mammalogy〔"()" Committee on Taxonomy. 2012. List of marine mammal species and subspecies. Society for Marine Mammalogy, www.marinemammalscience.org, consulted on May, 6 2012.〕 started considering the Bolivian (''Inia geoffrensis boliviensis'') subspecies as a full species, ''Inia boliviensis''. In 2014, the population in the Araguaia-Tocantins basin was recognized to be an additional species, ''Inia araguaiaensis''. *Genus ''Inia'' * *Species ''Inia geoffrensis'' - Amazon river dolphin * * *Subspecies ''I. g. geoffrensis'' * * *Subspecies ''I. g. boliviensis'' * * *Subspecies ''I. g. humboldtiana'' Alternate classification〔 *Genus ''Inia'' * *Species ''Inia araguaiaensis'' - Araguaian river dolphin * *Species ''Inia boliviensis'' - Bolivian river dolphin * *Species ''Inia geoffrensis'' - Amazon river dolphin * * *Subspecies ''I. g. geoffrensis'' * * *Subspecies ''I. g. humboldtiana'' 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「Inia」の詳細全文を読む スポンサード リンク
