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?
