Amazon river dolphin

The Bolivian River Dolphin, or Inia boliviensis, is one of four freshwater river dolphin species in South America. Locally known as bufeos, it is found in some rivers in the Upper Madeira Basin of the Bolivian Amazon. The Bolivian River Dolphins are separated from the Amazonian River Dolphins by a series of rapids and falls. The pink river dolphin is the largest freshwater dolphin in the world. It can reach up to 2.8 meters long and weigh as much as 180 kg. Compared to its cousin, the Amazonian River Dolphin (Inia geoffrensis), the Bolivian River Dolphin has more teeth, a smaller skull, and a longer body. Necropsies have shown the Bolivian River Dolphin diet includes a variety of different species of fish, as well as crabs. In the necropsy of a juvenile dolphin, multiple different species of fish from at least 4 different families were found in its stomach contents. It is also worth noting that none of the species present in this particular juvenile’s stomach were target species for fisheries.
