The Amazon River Dolphin, also called the boutu, boto, or bufeo, is the largest of the freshwater dolphins, and like all freshwater dolphins it is endangered because of hunting, human pressures, and degradation of habitat. Its most amazing characteristic is its color, which ranges — depending on its age — from soft, rosy pink to a vivid, almost shocking pink. The Portuguese name for this species in Brazil is “boutu vermelho” — red dolphin.
