Do Whales Really Sing?
Some baleen whales, particularly humpback whales and blue whales, produce a melodic sound known as a whale song.
However, it is important to understand that whales do not sing as we do as they do not have vocal cords and to make the sound they do not need to exhale as we do when we sing. This song changes from season to season, but again, all the males sing the same one. The purpose of the whale sing has ranged from reproduction to communication.
Whale songs can last up to thirty minutes and all the males in a pod sing the same song at the same time.
