The Sound of Humpback Whales

No one knows exactly how these whales sing, but they don't have to exhale to make sound like you and I do. Sound travels four times faster in water than it does through air,. In fact, the low frequencies of whale song can travel more than 10,000 miles given the right conditions. It seems that each group of humbac whales has their own style of song. By identifying that song, biologists can follow the migration habits of these aquatic composers.
