The Pink River Dolphin

Also known as the Amazon river dolphin, the pink dolphin thrives in freshwater and is characterized by its rosy hue and pointed rostrum. The river dolphin (also known as "boto") is grey all over when it's born and gradually obtains its pink color as it gets older. Pink river dolphins aren't picky eaters and enjoy chowing down on turtles, crabs, shrimp, and several species of fish. But pink river dolphin populations are vulnerable due to factors including mercury pollution and river and lake contamination
