There's something about this video that fills me with terror more than any other shark clip I've ever seen. It's not its monstrous looks, but the vision of it coming at you out of nowhere, accelerating until it engulfs your head with its jaws. The complete video is even worse.
It's terrifying to see this mako shark coming in again and again, systematically eating all its prey until everything is gone.
