The Ganges River dolphin is a dolphin found exclusively in the freshwater rivers of Bangladesh, India, and Nepal. They can only live in freshwater and are effectively blind. They hunt by emitting ultrasonic sounds which bounce of off fish and other prey, allowing them to "see" an image in their mind in an almost radar-like fashion. Generally they are found alone or in small groups, with the mother and calf usually traveling together. Calves are a chocolate brown at birth, and as they grow their skin begins to turn to a grayish brown complexion. Female Ganges River dolphins are larger than males, and give birth once every two or three years to a single calf.
