<p><br /> A scuba diver who came face-to-teeth with a shark used a camera to fend off the animal when it came at him - and he has the frightening video to prove it.<br /> </p><p><br /> Scott MacNichol, 30, was shaken up but uninjured after a porbeagle shark apparently mistook his camera equipment for food.<br /> </p><p><br /> MacNichol was diving near Eastport, off the eastern tip of Maine. He estimated the shark was 8ft long and weighed about 300 pounds.<br /> </p><p><br /> MacNichol saw the shark swimming above him while he was filming the ocean floor under empty salmon pens.<br /> </p><p><br /> The animal then came at him, jabbing at the camera with its snout. In the video, its sharp teeth fill the frame before it swims off.<br /> </p><p><br /> MacNichol said he was petrified at the animal's behaviour and screamed underwater.<br /> </p><p><br /> Porbeagles are coldwater sharks that have a similar body shape and tail to great white sharks.<br /> </p>
