river dolphins
Waterway swimming mammals
River dolphins are freshwater cetaceans found in major river systems of Asia and South America, including the Amazon, Ganges, and Yangtze.
Unlike their ocean-dwelling relatives, they have long, narrow snouts adapted for catching fish in murky waters, and many species have poor eyesight, relying instead on echolocation.
Most river dolphin species are endangered due to pollution, dam construction, and fishing nets.
