UNSEEN footage of what experts believe is the biggest great white shark ever caught on camera has been released. The seven meter-long female known as Deep Blue stunned the world last year when video was unveiled of it dwarfing cage divers off the coast of Guadalupe Island, Mexico. Now, diving enthusiast Michael Maier, 48, has released even more eye-catching clips of the giant female feeding on bait and inquisitively circling divers. Deep Blue, who is estimated to be at least 50 years old, was filmed by Michael in November 2013 - but these latest files were previously unseen.
