Possibly as few as several hundred North Pacific right whales exist on earth. Most of them are divided between two populations in the Sea of Okhotsk and the Bering Sea. They’ve been called the most endangered whales on the planet. Incredibly, their songs have recently been recorded for the whole world to hear. Scientists had recorded the whales’ calls before but weren’t sure of the source until a 2017 study, the results of which have just been released. The population that made these calls consists of only 30 whales that summer in the Bering Sea. It took researchers eight years of listening to make these recordings. Only males make the blunt, staccato calls, which researchers believe indicates they’re a mating call of some kind, possibly even modified to seek out a rare mate in miles of a whale-less ocean.
