The Ganges river dolphin was officially discovered in 1801. They are blind and live in freshwater, they hunt by emitting ultrasonic sounds, which bounces off of fish and other prey, enabling them to “see” an image in their mind. This is how they are able to feed and survive, they also live in groups.
