Every year humanity discovers new species or populations of existing species we had no idea about previously. You might think, however, that these are all creatures small enough to hide from our eyes, not the largest animal that has ever lived. Nevertheless, a previously unknown population of blue whales has been discovered living in the western Indian Ocean, one that may even represent a distinct subspecies of these ocean giants. The story began in 2017 when scientists from the African Aquatic Conservation Fund (AACF) detected a whale song they had never heard before in the waters between Mozambique and Madagascar. Whale songs can be detected up to 150 kilometers (90 miles) away in good conditions, so with the right equipment are much easier than visual detections of their makers. Blue whale populations have recognizably different dialects to their songs and researchers use these to identify a whale s tribe, but this was different from anything previously recorded.
