This is 'Deep Blue' one of the biggest great white sharks ever caught on camera. Deep Blue was captured during filming for Discovery Channels Shark Week 2014 which received some negative press for using actors and fake storylines in some of the programs that were aired during the week.
You will be pleased to know that this is not a computer generated shark and all the footage is actually real. The shark is estimated to be up to 50 years old and was almost as long as the 22ft boat it can be seen swimming under. You can check out more information on these impressive animals via Discovery Channel.
