Researchers had a spectacular encounter with a rare Greenland shark (Somniosus microcephalus), much deeper and far south of its normal range.
During a standard dive (but never a dull event, as the researchers mention), the shark carefully (and gracefully) checked out the submersible giving the video specialist plenty of time to shoot high qualityfootage (QuickTime et Windows Media Vomit). More information on this shark can be found over at Arctic Kingdom.
