April 19 (UPI) -- A mysterious river dolphin in Brazil, previously thought to be relatively silent, could offer new insights into the evolutionary origins of marine mammal communication. It turns out, the river dolphin scientists thought was solitary and mostly speechless actually boasts an impressive vocabulary. "We found that they do interact socially and are making more sounds than previously thought," Laura May Collado, a biologist at the University of Vermont, said in a news release. "Their vocal repertoire is very diverse." Because Araguaian dolphins are skittish, they're difficult to study. But Gabriel Melo-Santos, a biologist from the University of St. Andrews in Scotland, found a riverside fish market in Brazil where the normally shy animals come to be fed fish by the locals. R...
