Pretend you're a pro photographer filming a marlin's release from underwater. You've done this many times and everything is going smoothly. Then, out of nowhere, a monster mako shark shoots up from below you and tears up the marlin. Blood starts clouding the area. Do you a) freeze up, b) swim away, or c) keep shooting? Well, this happened to Australian photographer Al McGlashan, and he went with choice C. It was gutsy, but he scored some amazing and rare shots. Check out the video below and then click here to see a gallery of the still photos Al was taking and get an even better idea of what was going through his head when old snaggle-tooth showed up. By the way, this is a U.S. exclusive, so you saw it here first. If it had been me in this situation, there would have been more than fish blood in the water.
