“We now know that killer whales are one of the very few mammalian species that can learn new sounds and reproduce them. Dogs and cats, for example—there’s not a chance you could teach a dog to meow or a cat to bark. It’s a very rare ability to learn sounds and reproduce them. We can do it, as humans. Some primates can. Some of the whales can. The calls Moby Doll made in 1964—we still hear today from his kin group that still exists out there. If all roads lead to Rome, all oceans lead to Moby Doll.” OrcasKiller WhalesMoby DollOrca HistoryOrca SoundsWhale Sounds Book:The Killer Whale Who Changed the World Source: The Killer Whale Who Changed the World
