Susu or Ganges River Dolphin

Ganges River Dolphin, or Susu
(Platanista gangetica)
The distinguishing features of this dolphin are the long,
slender, compressed beak with its formidable array of teeth,
wedge-shaped forehead, small, degenerate, lensless eyes,
longitudinal slitlike blowhole, distinctly constricted neck, low,
ridgelike dorsal fin, and broad flippers cut off squarely at
their ends .
The inoffensive Susu may remain at the bottom of a river probing
about in the mud for two minutes. Being almost blind, it must be
guided to its food by the sense of touch in its long snout.
