Divers near Oahu were monitoring tiger sharks feeding off a decomposed sperm whale when they encountered what some would regard as their greatest fear, but for them, an incredible discovery – a great white shark.<br /><br />And it wasn't just any great white. According to marine biologist and conservationist, Ocean Ramsey, who is seen in the video, the shark in question was Deep Blue. The 20-foot-long creature is believed to be one of the largest on record and has created such a name for itself in the world of marine biology that it even has its own Twitter account.<br /><br />The filmer, who took the footage on January 15, recounted the incident to Newsflare.<br /><br />"When we first got there there were a bunch of tiger sharks feasting on the carcass and then suddenly they all swam away, probably sensing what was approaching," the filmer said.<br /><br />The 50-year-old shark later swam right by the carcass towards the divers, seemingly more interested in the group than the whale carcass.<br /><br />"She then made her way out to the surrounding boats to check them out as well. After that she slowly descended and swam off," the filmer said.<br /><br />Great whites are uncommon in Hawaii's warm waters, Ramsey said, but hunger could have driven the shark out of its comfort zone.<br /><br />State wildlife officials took to Facebook to discourage the public from approaching the rotting whale carcass and the wildlife it attracts, warning that the shark may mistaken divers as food.
