Found in India, which dolphin lives only in freshwater?

Ganges river dolphins once lived in the Ganges-Brahmaputra-Meghna and Karnaphuli-Sangu river systems of Nepal, India, and Bangladesh. But the species is extinct from most of its early distribution ranges.

The Ganges river dolphin can only live in freshwater and is essentially blind.

Once present in tens of thousands of numbers, the Ganges river dolphin has dwindled abysmally to less than 2000 during the last century owing to direct killing, habitat fragmentation by dams and barrages and indiscriminate fishing. It is for these reasons that despite high level of protection, its numbers continue to decline. The absence of a coordinated conservation plan, lack of awareness and continuing anthropogenic pressure, are posing incessant threats to the existing dolphin population.

The Ganges river dolphin inhabit freshwater river systems, mostly in plains with slow-flowing rivers. They have a preference for deep waters, where prey availability is high. They mainly feed on fish and invertebrates, using echolocation to detect their prey.
