Description Amazing whale encounter documents interaction between humans and playful Humpback Whales, sometimes referred to as "Dancers," in Tonga . The unique video, shot by Rob Barrel, owner of the live-aboard dive boat NAI'A, shows Humpbacks approaching humans free-diving in Tonga, south of Fiji. Highlights of the four-minute video clip show a whale spreading its pectoral fins as it mimicks diver John Tressman, another whale posing for author/photographer Paul Mila, and finally a humpback pirouetting for videographer Rob Barrel, and extending a pectoral fin attempting to make contact with him.
