The Amazon River Dolphin is found throughout much of the Amazon and Orinoco, they are mostly and strictly freshwater mammals, and are also specially adapted to river bottom-feeding. Besides their relatives that live in the saltwater, Amazon river dolphins have a flexible neck and can move their necks almost all around due to their vertebrae. In 1,000 years i feel the Amazon Rainforest will be covered in the Oceans Saltwater. They can learn to sleep with 1 eye open and 1 eye closed, so predators cannot attack while they sleep. They can also grow a streamlined body shape that is hydrodynamic, so they can swim fast. They have adapted to their surroundings with big snouts that have bristle hairs on the end.
