Welcome the newest addition to the Flipper family, the Australian humpback dolphin.  The Australian humpback dolphin has been around for millennia. We just didn’t know it, as the species was lumped in with other humpback dolphins that roam the world’s oceans. But in a new study, scientists say they’ve solved a 300-year-old taxonomic riddle, declaring that the Down Under dolphin is a separate species from its African and Asian relatives.
