NATURE OF HUMAN NATURE
Amazon
river dolphin, also known as the pink river dolphin or boto, lives only in
freshwater. It is found throughout much of the Amazon and Orinoco river basins
in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. It is a
relatively abundant freshwater cetacean with an estimated population in the
tens of thousands. However, it is classified as vulnerable in certain areas due
to dams that fragment and threaten certain populations, and from other threats
such as contamination of rivers and lakes.
