An Australian Blue Whale Project has used acoustic technology to track the rare Blue whales in the Antarctic’s Southern Ocean, identifying their location based on the noises the whales made, reported The Times.
The Blue whale is the largest whale species, making it the largest mammal in the world, yet is rarely seen in the Antarctic Ocean. The Australian research team located the Blue Whales from their unusual noises, enabling the researchers to locate the Blue whales. Once located, two of the Blue whales were satellite tagged and 23 biopsy samples were taken, to track the Blue whales’ feeding habits in summer, and to study how they forage, a process that took seven weeks.
The Blue whale can grow up to 30 meters and can weigh 180 tons. Its tongue is heavier than an elephant, and its heart is as big as a small car. The noises made by the Blue whale were heard hundreds of kilometers away! More than 600 hours of Blue whale songs were recorded and more than 26000 calls were recorded and analysed for the project.
The Blue Whale Project is proving that whales do not have to be killed to conduct scientific research, unlike the Japanese, who claim to slaughter whales in the interest of scientific research!
