Asian river dolphin

Also known as blind river dolphins, they use sound and sonar to navigate around in the murky waters of the Ganges river

Zahangir Alom

These dolphins have many local names throughout the countries where they are found, and most are related to the noise people hear when they surface to breathe. They are usually hunted for their meat and oil. Other threats include entanglement in fishnets during migrations and the construction of dams that block their migration routes and cause food shortages.

A population assessment in 2017 concluded that less than 5,000 individuals are remaining for the species, of which about 1,500 of the Indus subspecies and 3,500 belong to the Ganges.

WWF and IUCN are working with local governments of Nepal, India, Pakistan, and Bhutan to ensure their survival.
