New population of blue whales discovered in western Indian ocean: Study
Scientists have found evidence of a previously undiscovered population of blue whales living in the western Indian ocean based on an analysis of sound recordings from the region, an advance that sheds light on the global distribution of the largest animals to have ever lived on the Earth.
While these highly endangered mammals are found around the globe in all oceans and sing very low-pitched and recognisable songs, the researchers, including those from the New England Aquarium in the US, said every blue whale population has its own unique song.

Do you ever hear a new song and realize it’s unlike anything you’ve heard before? I felt that a few times this year, mostly with Phoebe Bridgers and Polo G. It happened to scientists recently, too. But it wasn’t a new singer or rapper they discovered; it’s a new population of whales.

In a study published in the journal Endangered Species Research last week, scientists analyzed underwater recordings from the Arabian Sea, extending from the coast of Oman as far south as Madagascar. The team of researchers came across an unfamiliar kind of whale song that had never before been documented in 2017, sparking an international effort to discover the new singer.
