Blue Whale Song

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.

A team of Australian and New Zealand researchers has tracked scores of blue whales off Antarctica, eavesdropping as the world's largest animals began their rumbling song, which can be detected 750 kilometres (465 miles) away.

An Australian-led group of scientists has for the first time tracked down and tagged Antarctic blue whales by using acoustic technology to follow their songs, the government said Wednesday.

Australian scientists are using military technology for locating submarines to track rare blue whales hundreds of kilometres away by eavesdropping on their distinctive songs. Blue whales can communicate with each other over an entire ocean basin by emitting low frequency sounds, or deep songs.
