Habitat of Dolphin

The Kulsi river is the habitat of endangered South Asian river dolphin (Platanista gangetica). This endangered dolphin (known as Xihu in Assamese language) breeds only in Subansiri River and Kulsi River of the entire Brahmaputra delta.[1] However, sand mining and other development activities make dolphins in the Kulsi river vulnerable and the abundance of this endangered dolphin has sharply declined.
