Perception of Surfers

I saw that, but i flipped that video into HD, went full screen and paused it frame by frame. That is absolutely not a person. That is a shark. In the final frame when you can see the tail, I could see from that angle that it looks like a dolphin. I mean, you can see the nose, mouth, dorsal, side fins and tail. The only way that's a person is if its a dude in the most intricate "grey suit" ever constructed. I see what you mean about the camera man etc, but that is a marine animal.
