As Andrew Stevenson and his young daughter Elsa watched a 50-ton humpback launch itself out of the water off a Bermudan beach, she asked, 'Why does a whale breach?' This was the spark behind the challenge to film the whales underwater that became an overriding passion. The first to admit he is not a marine biologist, Stevenson's "Humpback Whale Film and Research Project" has nonetheless provided remarkable scientific evidence of the whales' lives in Bermudan waters as well as their Caribbean breeding sites and Canadian feeding grounds. It has also resulted in this heart-warming, insightful tale of Stevenson's journeys with these awe-inspiring creatures.
