That's the sound of an endangered blue whale singing only 70 miles off of New York City's coastline. The whale was on its way to Maine for the summer, after wintering in Florida. Scientists from Cornell studying the acoustic environment of New York waters released the audio today and were thrilled to come across the sounds. New York State’s Department of Environmental Conservation Commissioner Pete Grannis says blue whales had been practically hunted to extinction by the mid-20th century, and now they're threatened by ships and debris.
Conservationists say the new findings are indispensable and will help them develop protection plans for the whales, which are the largest animals ever to have lived on earth.
