'''Indian dolphins''', belonging to the genus ''Platanista'', are toothed whales found in the waterways of the [[Indian subcontinent]]. Historically, they were regarded as a single species (''P. gangetica''), with the Ganges river dolphin and the Indus river dolphin considered subspecies (''P. g. gangetica'' and ''P. g. minor respectively''). However, due to genetic and morphological studies, they were reclassified as distinct species in 2021. It is estimated that the Ganges and Indus river dolphins diverged around 5,50,000 years ago. These dolphins are the sole surviving members of the family ''Platanistidae'' and the superfamily ''Platanistoidea''. Fossils of their ancient ancestors have been traced back to the late Oligocene period. | '''Indian dolphins''', belonging to the genus ''Platanista'', are toothed whales found in the waterways of the [[Indian subcontinent]].
