In the present, pink river dolphins live in the freshwater of the amazon rainforest. They can turn their head sideways because their neck bones aren't fused. Their pink color can get brighter when they're excited or active. Pink river dolphins are also called botos. They have poor eyesight, but excellent echolocation. They sometimes use sticks or plants as toys, showing playful behavior. In the future, when pink river dolphins get older they start to look like elephants. They will live in the arctic. They will eat seals for food. In the future, pink river dolphins will also be called pink arctic elephins. They are also nocturnal in the future.
