River dolphins are thought to have relictual distributions, that is, their ancestors originally occupied marine habitats, but were then displaced from these habitats by modern dolphin lineages. [ 12 ] [ 13 ] Many of the morphological similarities and adaptations to freshwater habitats arose due to convergent evolution ; thus, a grouping of all ...

Bolivian river dolphins were discovered by the Western world in 1832 by French researcher Alcide d'Orbigny. [2] The Bolivian river dolphin was briefly thought to be a subspecies (as I. geoffrensis boliviensis) of the Amazonian river dolphin, Inia geoffrensis, but differences in body structure and the isolation of the Bolivian river dolphin led to it being classified as its own species in 2012.
