Woman Swims With Great White Shark Feb 182013 To promote their new HD HERO2 camera, Go Pro Camera teamed up with veteran freediver Ocean Ramsey for some jaw-dropping underwater footage. Incredibly, she swims with one of the largest fish in the sea, the Great White Shark, all under the lens of the Hero2. Now, the video has already collected over 390,000 views over the weekend, and is further covered by EpicTV, NYDailyNews, and GMAYahoo. Porcelina Actually, the largest fish in the ocean currently known is the Whale Shark. I say “currently known,” since there may be even larger fishes in the deep sea that have yet to be scientifically documented.
