Gangetic Dolphin

The Ganges river dolphin, also known as the susu, is one of the world's few freshwater dolphin species and the national aquatic animal of India. Nearly blind due to poorly developed eyes, it navigates and hunts entirely by echolocation in the murky waters of the Ganges-Brahmaputra river system. Listed as Endangered, it faces threats from river pollution, dams, fishing nets, and sand mining which degrade its riverine habitat.
