Giant Shark filmed off Japan - "When trying to ascertain its size, researchers took into account the dimensions of the bait container, as well as the length of other sharks that can be seen in the footage before the monster shows up, which were judged to be around 2 meters (6.5 feet) long. Using these as size comparisons, the mystery shark was estimated as being at least 30 feet long, with more exaggerated estimations putting it at more like 50 or 60 feet long."
