Amazon pink dolphin mother with baby

The rare, freshwater Amazon pink dolphin is in trouble. It lives in the Amazon River basin, which is being altered by rapid industrialization, logging and agricultural activities that threaten the dolphin’s habitat. Little is known about the dolphin (though some local tribes worship it as a wizard, or at least a wise human). It’s brain capacity is 40% larger than humans, and it gets its pink color from capillaries on the surface of its skin (perhaps to aid in heat exchange in the humid Amazon).
