Context: New population of blue whales discovered in western Indian Ocean

• 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 which sheds light on the global distribution of the largest animals to have ever lived on the Earth.
• These highly endangered mammals are found around the globe in all oceans, and sing very low-pitched and recognisable songs, every blue whale population has its own unique song.
• The scientists analysed recordings from the Arabian Sea coast of Oman, and as far south as Madagascar, and found a blue whale song that had never been described.
