A pod of humpback whales bubble net feed near North Pass between Shelter and Lincoln Islands (below) and off the shore of South Shelter Island (right). Humpbacks have one of the most inventive feeding methods of all whales. When bubble net feeding on krill and small fish, they will blow bubbles while swimming in circles to create a ring of bubbles. The ring encircles the fish and becomes tighter as the pod swims in smaller circles until eventually the whales swim upward through the bubble net with mouths agape, swallowing thousands of fish in one gulp.
