Sharks have everything a scientist dreams of. They're beautiful―God, how beautiful they are! They're like an impossibly perfect piece of machinery. They're as graceful as any bird. They're as mysterious as any animal on earth. No one knows for sure how long they live or what impulses―except for hunger―they respond to. There are more than two hundred and fifty species of shark, and everyone is different from every other one.
In school I ended up writing three different papers on "The Castaway" section of Moby-Dick, the chapter where the cabin boy Pip falls overboard and is driven mad by the empty immensity of what he finds himself floating in. And when I teach school now I always teach Crane's horrific "The Open Boat," and get all bent out of shape when the kids find the story dull or jaunty-adventurish: I want them to feel the same marrow-level dread of the oceanic I've always felt, the intuition of the sea as primordial nada, bottomless, depths inhabited by cackling tooth-studded things rising toward you at the rate a feather falls.
