For centuries the haunting melody of whale song was thought to come from ghosts, mythical sea creatures or the imagination of drunken sailors.

While we now know whales can sing, until now scientists haven't fully understood how species such as humpback or blue whales actually produce sound. Now researchers in Denmark have managed to reconstruct a whale's larynx discovering more about the vocal evolution of these massive mammals.
