Araguaian River Dolphin

Caption

This is an Araguaian river dolphin swimming in the Araguaia River near a fish market in the Brazilian town of Mocajuba that the animals regularly visit to be fed by the people shopping there. Normally they are hard to find and study. Researchers from the University of Vermont and University of St. Andrews discovered that the dolphin species, which was thought to be solitary and quiet, can actually make hundreds of different sounds, a finding that could help uncover how communication evolved in marine mammals
