Blind Dolphins are found in:

The Ganges River Dolphin (Platanista gangetica gangetica) indeed lives up to its nickname: functionally blind. Its environment—the well-mixed, murky waters of the Ganges-Brahmaputra-Meghna river system—makes its vision almost useless. A close relative of this dolphin, the Indus River Dolphin (Platanista gangetica minor), suffers the same fate and also bears the same nickname: the “blind dolphin.”
