The Amazon River basin is home to several species of river dolphins, also called botos. In 2014, a group of scientists headed by biologist Tomas Hrbek published a study announcing the discovery of a new river dolphin species.
The study concluded that dolphins found in the Araguaia River in Brazil are distinct from their cousins elsewhere in the Amazon. The Araguaian botos share some characteristics with other Amazon dolphins, like a long, toothy beak and pink-gray skin. However, Araguaian botos appear to have a different number of teeth, unique skull features, and slightly different DNA.
Not everyone is convinced, though. Hrbek's team could examine only a few animals, and critics argue that more specimens need to be studied. If the study's findings are confirmed, however, the Araguaian boto would be the first new river dolphin species discovered in almost a hundred years!
