The mechanism of whale singing discovered - Nature. The discovery was published in the journal Nature by Coen Elemans' group, from the Biology department of the University of Southern Denmark.
It is a very particular larynx that makes whale song so evocative, but at the same time the characteristics of this organ mean that the song is disturbed by the noise of ships. This data, the authors of the research observe, suggests that communication between whales would be seriously affected by human activity.
