If you've ever seen Finding Dory, the sweet and funny sequel to box-office hit Finding Nemo, you'll know what it means to'speak whale.' Without the help of a befuddled beluga whale called Bailey, the film's forgetful fishy heroine would never escape the fictional Marine Life Institute and "just keep swimming" to find her long-lost parents. Thanks to robotics and artificial intelligence (specifically natural language processing powered by machine learning), it might also be possible to understand whale lingo outside Disney-Pixar's imaginary kaleidoscopic multiverse. In probably the most significant interspecies communication project of all time, researchers recently set about the titanic task of translating the Morse code-like series of clicks (or codas) used by sperm whales to chat with one another. And the results of Project CETI will no doubt be far more interesting than human discussions around the price of fish -- or any other clever piscine reference you can think of.
