A new species of river dolphin has been spotten in Brazil -- the first time a river dolphin has been reported since 1918. Scientists say it is only the fifth known of its kind in the world, and discovered in the Araguaia River basin in Inia. They urge the international community to consider the dolphins vulnerable as so few are known to exist.
