It's a funny thing about great white sharks (and that's not a contradiction in terms). They smile. Exactly the kind of smile you would expect to get if you crossed the Cheshire Cat with Dracula. Coming straight at you, the expression is downright unnerving. Here's this one-ton plus eating machine, the top Piscean predator in the sea, with a mouth big enough to swallow you whole and teeth serrated like steak knives, and it's grinning at you as it makes its approach. A frozen grin, to be sure, but one as unmistakable as that of any porpoise.
Then it opens its mouth, and the grin goes away, to be replaced by a black gullet as dark and profound as the entrance to the River Styx. Which, if you are not suitably aware and guarded, it very well might become.
