The Ganges River dolphin, also known as the Susu, is a freshwater dolphin found primarily in the Ganges, Brahmaputra, and Meghna river systems in South Asia. This species is known for its distinctive pink color and long, slender body, which can reach lengths of up to 2.5 meters. They are adapted to living in murky waters, relying on echolocation to navigate and hunt for fish. Ganges River dolphins are considered endangered due to habitat loss, pollution, and entanglement in fishing gear. Conservation efforts are underway to protect their populations and habitats, highlighting the importance of preserving these unique aquatic ecosystems.
