Meet the Dolphin

India's National Aquatic Animal

The Gangetic dolphin (Platanista gangetica gangetica) is a freshwater dolphin found in the Ganga river system — functionally blind, and superbly adapted to hunt in turbid water using echolocation.

  • Freshwater habitat — lives exclusively in river systems, never the open sea
  • Echolocation — navigates and hunts using sound, not sight
  • Behaviour — generally solitary, surfacing periodically to breathe
  • Conservation status — Endangered on the IUCN Red List

Did You Know?

Gangetic dolphins have no lens in their eyes, leaving them essentially blind. They rely almost entirely on echolocation to navigate and find prey in the Ganga's often-murky waters.
