Dr. James Darling, renowned whale researcher and co-founder of the West Coast Whale Research Foundation, sheds light on the reasoning behind whale vocalization. Whales sing to one another over hundreds of miles and use their songs to navigate across oceans. Humpback whales travel thousands of miles as a group, singing to each other as they go. They can also communicate with each other over thousands of miles of ocean. The presenter explains how singing is part of their social system and community.
