The Brahmaputra river dolphin, also known as the Ganges river dolphin, is a freshwater dolphin species found primarily in the Brahmaputra River and its tributaries in India, Bangladesh, and Nepal. These dolphins have a distinctive appearance, with a long, slender body and a rounded forehead. They are known for their grayish-pink color, which can vary based on water conditions. Brahmaputra river dolphins are social animals, often seen in small groups. They primarily feed on fish and other aquatic creatures, using echolocation to navigate and hunt in the murky waters. Unfortunately, they are classified as endangered due to habitat loss, pollution, and fishing activities.
