Humpback whale song
Humpbacks are the noisiest whales, with males 'singing' for up to 15 minutes at a time. The sounds they make are the most varied in the animal kingdom, ranging from high-pitched squeals to low, rumbling gurgles. Only males 'sing' and experts think they do it to attract females or to let other males know they're in the area. Check out this cool clip!
