After spending 400 hours over the course of 100 missions, Japan's NHK TV crew has managed to film the mysterious sea creature for the first time ever. The squid was spotted last summer in the Pacific Ocean--at a depth of 630 meters about 1,000 kilometers south of Tokyo--during a joint expedition by the Japanese public broadcaster, Discovery Channel and the National Museum of Nature and Science. The footage will premiere in the upcoming Discovery Channel special documentary that will air on January 27.
