Cape Town - When a scuba diver off the coast of Florida found himself face to face with a Great White shark, instinct kicked in and he managed to fend the predator off with his speargun. And get this... he filmed the entire incident with a GoPro attached to his head!Check out the video. People.com reports that Jimmy Roseman was diving at Bethel Shoal off the Florida coast when a terrifyingly familiar silhouette appeared just a few metres away from him in the murky water. Rather aptly set to the Jaws theme, the video shows a fin nicking the camera and then a large body disappearing into a cloud of sand... the 12ft shark reappears shortly after, heading straight for Roseman.The diver's instincts quickly kick in and he starts fighting the apex predator off with his speargun. We don't know about you, but think that's rather clear thinking and quick reaction, especially 27 metres underwater. Although this is way more extreme, it kind of reminds us of this video of a diver narrowly escaping a shark attack in the Caribbean.
