The Amazon river dolphin, also known as the boto, is a freshwater dolphin found in the rivers and lakes of the Amazon Basin in South America. These dolphins are known for their distinctive pink coloration, which can vary from gray to bright pink as they age. They have a long, slender body and a flexible neck, allowing them to navigate through the complex river systems. Amazon river dolphins primarily feed on fish, crustaceans, and other aquatic animals. They are social creatures, often found in small groups, and are known for their playful behavior. Unfortunately, their populations are threatened by habitat loss, pollution, and fishing activities.
