The Gangetic River Dolphin (Platanista gangetica), commonly known as 'Susu', is one of the recognized obligate freshwater dolphins, distributed along Ganges, Brahmaputra, Karnaphuli–Sangu and Meghna river systems and their tributaries from the foothills of the Himalayas to the limits of tidal zone in India, Bangladesh, Nepal.
Being the only mammalian predator of the Ganges which is exclusively aquatic, it occupies the apex of the food chain and plays a vital role in maintaining the essential balance of its ecosystem.
The species is facing a series of threats for its survival due to poaching, construction of dams and barrages (habitat fragmentation), pollution, mining of sand and stones (habitat degradation) and incidental catches in gillnets of fishermen hence been placed in Schedule-I of Indian Wildlife (Protection) Act, 1972, Appendix I of CITES (Convention on International Trade in Endangered Species) and also listed as 'Endangered'.
