Amazon River dolphin

The Amazon River dolphin, or boto, is one of only five living species of river dolphin on the planet, and it is the world's largest. This dolphin occupies the murky waters of the Amazon and Orinoco basins of South America, frequently found swimming amongst the trees in the flooded forest. The species is also often referred to as the "pink dolphin," due to the occasional pink hue of its skin.
