Sharks kill fewer than 25 swimmers a year, experts say, while men wantonly slaughter sharks.

Today they are seen as crucial keepers of nature's delicate undersea balance, a potentially endangered species more sinned against than sinning. Since then, sharks, once frightful man-eating scourges of the deep, have graduated - like wolves and killer whales - to a more benign role. We watched them chomp on the wooden sterns of fishing boats or gnaw on steel antishark cages in documentaries while scuba divers photographed them in places like Tasmania and Madagascar, and shivering couch potatoes learned what remorseless killing machines great whites really are. The toothy creatures eventually became as relentlessly ubiquitous as David Letterman. The book gave him considerable riches and renown and, with a little help from Steven Spielberg, created a generation of American children afraid to swim in anything deeper than a well-lighted finger bowl. TWENTY years have passed since Peter Benchley, then a young writer with a famously funny grandfather, loosed "Jaws" upon the world.
