Did you know: Humpback whales produce the longest and most varied songs in the animal world. These intricate vocalisations range from high squeaks to low guttural growls. These songs are produced by moving air back and forth through body passages. Analysis has shown that the sounds produced are organised into long sequences. Each sequence normally lasts 10 - 15 minutes and can be repeated without pause, for hours. The sequences are always arranged into cycles characteristic of each population, so that all humpbacks in one area sing only the local song. These songs evolve with time and each year the song is a little different, but every change is picked up and incorporated into the current sequence.
