New Blue Whale Population Discovered

A new population of blue whales has been found living in the Indian Ocean after scientists heard a new song travelling hundreds of miles through the sea.

Blue whale vocalisations are very low and can reach other whales through the water up to 500 miles away. Each blue whale population has their own unique song. Scientists were amazed when they heard blue whale calls that had not been reported before.

They compared their recordings with other scientists studying blue whales and discovered that these blue whales live in waters ranging from the Arabian Sea coast of Oman across to the Chagos Archipelago in the central Indian Ocean, and as far south as Madagascar in the southwest Indian Ocean.

The blue whale is one of nature’s most magnificent and graceful beings - larger, longer and heavier than any other creature on Earth.

The discovery of this new population is very exciting because, although once there may have been over 350,000 blue whales in our oceans, commercial whaling wiped out 90% of them and they are now endangered with only between 10,000 and 25,000 individuals left.
