Humpback Whales or we can say flying monsters, are famous for their magical songs/sounds. Their sound travels for great distance throughout the oceans. These sounds or we can say moans,cries,howls and other noises are very complex and hard to understand even with latest technology. Sometimes these sounds continue for hours and even for a day. Scientists are trying and studying these sounds to interpret their meaning but they haven't got any result yet. But they have many hypothesis for that. Their result induced that they sing and produce sounds just to talk to each other or communicate with each other.
