this is terrific video of humpbacks off Hawaii, taken by

Jason Sturgis, 31.  he is belived to be the first person to capture

underwater scenes of humpbacks frolicking in the waters of Hawaii

(using a Sony HVR-Z1U high-definition video camcorder)

    See the Video

     the humpback whale (Megaptera novaeangliae) belongs to the

baleen whale suborder (so-called because they have baleen plates

instead of teeth in the upper jaw, which enables them to filter food

from water).

    humbacks are large: an adult usually ranges between 40–50 feet

long and weighs approximately 79,000, 40 tons.  humbacks are 

known for their breaching (leaping out of the water), their unusually

long front fins, and their complex whale songs.  they live in oceans

and seas around the world, and are regularly sought out by whale-watchers.
