description Ganges River Dolphin Overview

The Ganges river dolphin (Platanista gangetica gangetica) is an endangered cetacean found in the Ganges, Brahmaputra, and Meghna river systems of South Asia. Because it lives in muddy, turbid waters, the dolphin is functionally blind, lacking a crystalline lens in its eyes, and relies entirely on echolocation to hunt prey. It is notable for its unusual side-swimming behavior and was designated the National Aquatic Animal of India. The species faces severe threats from habitat loss, pollution, and entanglement in fishing gear.
