Off the coast of Mexico, National Geographic Explorer Bertie Gregory spots a lifeless creature dangling from a fishing line. With a bulging head that looks like it swallowed a gavel, there's no mistaking the animal: It’s a hammerhead shark. Gregory captured the heartbreaking footage while filming Hammerheads Up Close, premiering July 5 on Disney+ and Hulu and airing on National Geographic at 9/8c. In the show, the wildlife filmmaker scours the Pacific waters looking for hammerheads and examines why their numbers have plummeted in recent years.
