The Ganges River Dolphin (Platanista gangetica), also known as the blind dolphin, is found in the Ganga and Brahmaputra river systems and their tributaries in India. The dolphins got their nickname because of their adaptation to the muddy waters of the rivers. They developed small non-functional eyes and rely on echolocation to navigate and locate food. The Ganges River Dolphin was declared India’s National Aquatic Animal in 2009.
