Where the humpback whale sings

Oceans cover more than 70% of the Earth's surface, so it's no surprise they play a crucial role in our planet's climate and ecosystem. These gargantuan seas support a vast ecosystem of marine life, including the beautiful humpback whale. The humpback whale once was known for its 'singing', which researchers attributed to possibly be a sign of loneliness. The good news is that as the whale population has risen with the end of commercial whaling, there is less need for whales to sing a song of loneliness.
