The 2017 National Geographic Explorer of the Year -- and one of National Geographic’s most seasoned photographers -- will help you discover a vast, hidden world beneath the waves. His images celebrate the mystery of the depths and offer portraits of creatures so intimate they sometimes appear to have been shot in a studio. The 11-time award winner in the Wildlife Photographer of the Year competition, Skerry dives eight months of the year, often in extreme conditions beneath Arctic ice or in predator-infested waters.
