Sea King -- Orca, Japan
Rumors of a "superpod" of orcas, or killer whales, numerous in number, lure the Darwin team to the Shiretoko Peninsula in Japan's extreme north. But much lies below the surface out of view, forcing us to employ a range of tools to monitor these amazing creatures that can reach 10 meters in length and weigh 10 tons. We soon discover what makes these seas so attractive: a smorgasbord of marine life preferred by orcas. But "speed dating"? There they are, lined up in a row. Highly "orca-started"!
