This is a video from Cape Shanck, Victoria, Australia (about an hour and a half south of Melbourne) of a diver who looks up to realize there’s a great white swimming right above him.
Like RIGHT above him — just feet away. So what’s the protocol in this situation? “Shit your wetsuit.” And then? “Shit it till your bowels run dry.” Cool, so exactly what I would have done.

Keep going going for the video.
