Inia

Inia is a genus of river dolphin containing one to three 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. A 1998 classification[1] 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.[2] In 2012 the Society for Marine Mammalogy[3] 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.[4]

Alternate classification[3]
