Scott MacNichol, 30, came face-to-face with a shark while diving off the eastern tip of Maine. MacNichol recorded the encounter with his video camera. The 8-foot-long porbeagle shark appeared to be going after the camera and not the diver. MacNichol said, "He took a couple of bites at the camera. When he did that I was pretty much petrified. If you watch the video, you can hear me screaming underwater."
