Bold Sam Cahir refused to panic in the real-life Jaws scenario – instead producing his camera to capture these incredible shots.
Aussie Sam had been taking part in a Great White tagging trip when he found himself face-to-face with the deadly predator off the Neptune Islands, South Australia.
The Shortfin Mako shark – which have been known to attack humans – eventually left after eating tuna baits thrown into the water.
