Jaws- Eating Boy

There was no conviction that what thrashed above was food, but food was not a concept of significance. The fish was impelled to attack: if what it swallowed was digestible, that was food; if not, it would later be regurgitated. The mouth opened, and with a final sweep
of the sickle tail the fish struck.

He had no time to cry out, nor, had he had the time, would he have known what to cry, for he could not see the fish. The fish's head drove the raft out of the water. The jaws smashed together, engulfing head, arms, shoulders, trunk, pelvis, and most of the raft. Nearly half the fish had come clear of the water, and it slid forward and down in a belly-flopping motion, grinding the mass of flesh
and bone and rubber. The boy's legs were severed at the hips, and they sank, spinning slowly, to the bottom.
