Indus River Dolphins

The Indus river dolphin is one of the world’s rarest mammals and the second most endangered freshwater river dolphin. It is one of the flagship species and is an indicator of the biological health of the aquatic and terrestrial environment adjoining the Indus River.
  • Today, they can only be found in the lower parts of the Indus River in Pakistan and in River Beas, a tributary of the Indus River in Punjab, India.
  • They have adapted to life in the muddy river and are functionally blind. They rely on echolocation to navigate, communicate and hunt prey including prawns, catfish, and carp.
  • They are classified as Endangered as per the IUCN Red List.

Gangetic Dolphin 
  • The Ganges river dolphin was officially discovered in 1801. Ganges river dolphins once lived in the Ganges-Brahmaputra- Meghna and Karnaphuli-Sangu river systems of Nepal, India, and Bangladesh. But the species is extinct from most of its early distribution ranges.
  • The Ganges river dolphin can only live in freshwater and is essentially blind. They hunt by emitting ultrasonic sounds, which bounces off of fish and other prey, enabling them to “see” an image in their mind.
  • Ganges river dolphins prefer deep waters, in and around the confluence of rivers. The distribution range of the Ganges river dolphins in India covers seven states namely, Assam, Uttar Pradesh, Madhya Pradesh, Rajasthan, Bihar, Jharkhand and West Bengal.
  • They are classified as Endangered as per the IUCN Red List.
Irrawaddy Dolphins
  • Irrawaddy dolphins are found in coastal areas in South and Southeast Asia, and in three rivers: the Ayeyarwady (Myanmar), the Mahakam (Indonesian Borneo) and the Mekong.
