Sharks have everything a scientist dreams of. They’re beautiful―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.
The fish was an enemy. It had come upon the community and killed two men, a woman, and a child. The people of Amity would demand the death of the fish. They would need to see it dead before they could feel secure enough to resume their normal lives.
Look, the Latin name for this fish is Carcharodon carcharias, okay? The closest ancestor we can find for it is something called Carcharodon megalodon, a fish that existed maybe thirty or forty thousand years ago. We have fossil teeth from megalodon. They’re six inches long. That would put the fish at between eighty and a hundred feet. And the teeth are exactly like the teeth you see in great whites today. What I’m getting at is, suppose the two fish are really one species. What’s to say megalodon is really extinct? Why should it be?
“He decided to just keep afloat, treading water and hoping that something- who knows what? – would turn up to save him. But what if a shark, or some big fish, a horse mackerel, turned up? What was he supposed to do to protect himself? He didn’t know.”
“Cook, if you are ever captured by pirates, or surrounded by Indians, or if you should fall into the sea and be chased by a shark, I will see to it that this day’s work is not forgotten, if it costs me the last drop of my blood.”
