Researchers Believe A New Population Of BLUE WHALES Use An Entirely New Sound That’s NEVER BEEN HEARD BEFORE!

International researchers have identified a possible new population of blue whales in the Indian Ocean by a song that’s never been heard by human ears before. There are multiple populations of blue whales that live in the area and are each identified by their own set of unique sounds. However, scientists could not ascribe the brand new sound they heard to any particular gam of whales, pointing to an unobserved new population.
