Jaws - Half-mile

The great white had tracked his target into water too shallow for him. Now he gave up and turned seaward again.
Before him, a half-mile sphere of water emptied of life, for he was not alone in his sensitivities: his own prey had receptors, psychic and physical, much like his.
A huge skate, gliding at ten fathoms, flapped away to sea. A giant squid on the bottom squirted like a rocket into Amity Sound: Something was above that it did not like.
A school of cod, acting with a single brain, panicked and headed for land.
