Dolphins Up Close with Bertie Gregory

Résumé

Bertie Gregory is in the Azores, a marine sanctuary and vital pitstop for migrating ocean predators off the coast of Portugal. It's feeding season, as thousands of normally elusive predators join forces to hunt and feed on super-shoals of fish known as bait balls. A vast ocean and battling storms challenge the team for a chance to film the most spectacular feeding frenzy of Bertie's career.
