Video: Humpback whales feed in Prince William Sound

Humpback whales feed in a truly unique way called bubble net feeding. These baleen whales swim in a circle around a school of fish, blowing bubbles to confine the fish. The ring of bubbles encircles the school and eventually the whales break the circle and gulp thousands of fish in one swallow. In this video shot by AkXPro Productions, a pod of humpback whales feeds in Prince William Sound while a drone hovers overhead.
