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.
