Inia geoffrensis, commonly known as the Amazon river dolphin or boto, is a freshwater dolphin found primarily 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, especially in males. They have a long, slender body and a flexible neck, allowing them to navigate through the complex river environments. Botos are social animals, often found in small groups, and they primarily feed on fish and crustaceans. Unlike many marine dolphins, they have a more rounded forehead and lack a beak, giving them a unique appearance. Their habitat is threatened by pollution and habitat loss, making conservation efforts essential.
