Highly endangered and rarely seen, there are several species of animals called “river dolphins.” These creatures are not actually dolphins, but ancient species of whales. They live in the Amazon, Indus, Ganges, and Yangtze rivers. The Amazonian river dolphin, or “boto,” is also known as the pink dolphin for its distinctive colour. These animals are fast disappearing, however, threatened by pollution, dams, and fishing nets. The Chinese river dolphin is the most endangered, numbering less than 100 individuals.
