Inia is a genus of river dolphin containing one or possibly two species.
Taxonomy [edit]
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. The most recent 1998 classification[1] listed a single species, Inia geoffrensis, in the genus Inia, with three recognized subspecies. Most of the scientific community accepts this single species classification, as does the IUCN.[2] In 2012 the Society for Marine Mammalogy[3] started considering the Bolivian (Inia geoffrensis boliviensis) and Amazonian (Inia geoffrensis geoffrensis) subspecies as full species Inia boliviensis and Inia geoffrensis, respectively.
