Featuring the expansive knowledge and skill of acclaimed National Geographic Explorer and Photographer Brian Skerry, the series ventures deep into the world of whales to witness the extraordinary communication skills and intricate social structures to reveal life and love from their perspective. Secrets of the Whales unveils new science and technology to spotlight whales as they make lifelong friendships, teach clan heritage and traditions to their young, and grieve deeply for the loss of loved ones.
