If you've been in the ocean, there's been a shark not that far from you, and it knew you were there, and you probably had no idea it was there and had a pleasant day in the water. The sharks that do bite people, they take a little bite and they go, what is that? And swim away. That can be real bad if it hits a major artery or if you're far from shore. Again, I don't want to minimize the real harm. But it is not a shark hunting you because it has a taste for human flesh. They don't have hands. They explore their environment with their mouths and most things in their environment they can eat. I think Mythbusters tested fish blood versus mammal blood versus chicken blood, I think. And the sharks were attracted to fish blood and had no reaction to the others. So these are animals that are very, very, very well adapted for environmental conditions that in some cases don't really exist anymore.

Universal Pictures The survivors paddle their way back to shore. With humans, most of the time, what happens is an immediate bite, and then they swim away. With seals or large prey, they'll often hit it really hard from below, sometimes knocking it completely out of the water. Or if they're hunting whales or something that they can't fit in their mouth, they just take a huge bite and swim away. With fish, they swallow them whole to the extent possible. Sometimes there's a shaking motion to snap a neck or whatever. You see that with some land predators, too. It's nothing like what's seen there—but what an awesome scene. Ars Technica: What is your favorite scene in Jaws and the one that makes you cringe the most? David Schiffman: Oh, man. It's really a great movie, and it holds up well. It was hailed as revolutionary at the time because you hardly ever see the shark. But the reason they did that was because the model of the shark that they built kept breaking. So they decided, let's just shoot it from the shark's eye view and save money and annoyance. I love the scene when Hooper realizes that the tiger shark that they've caught is obviously not the right species and the reaction that people have to that—just this idea that science and expertise can be used to solve problems. Whenever a shark bites someone, there are people who go out and kill any shark they can find and think that they're helping.
