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