New genetic analysis and years of painstaking research has revealed that one of the world's most endangered marine mammals is actually two species rather than one, as scientists had long assumed.

 
Scientists spent about two decades crossing Asia and Europe in pursuit of river dolphins skulls and reexamining tissue samples with modern genetic techniques. Their findings revealed that Indus and Ganges river dolphins are separate species, according to a new study published in Marine Mammal Science.
