Peter Benchley’s 1974 novel Jaws was an immediate success upon release and was subsequently adapted into the blockbuster Steven Spielberg movie of the same name the following year. But despite the book putting Benchley on the map and making him a millionaire, the author began to second-guess his work as time went on. “What I now know, which wasn’t known when I wrote Jaws, is that there is no such thing as a rogue shark which develops a taste for human flesh,” Benchley was quoted as saying in 2000. “No one appreciates how vulnerable they are to destruction.”

Furthermore, Benchley explained that he never would’ve written the hit novel if he’d realized how much damage it would do to the reputation of the great white shark. After the book’s debut, Benchley became a shark expert and spent the rest of his life advocating for the creatures he’d unintentionally demonized. “Considering the knowledge accumulated about great whites in the past 25 years, I couldn’t possibly write Jaws today…not in good conscience, anyway,” Benchley told the Cape Cod Times ahead of the premiere of his National Geographic documentary Great White, Deep Trouble.

According to scientist Simon Thorrold of the Woods Hole Oceanographic Institution, Jaws helped legitimize shark hunting. An estimated 50 to 100 million sharks are killed by humans each year, but sharks are only responsible for a small number of human deaths by comparison. “If you bought into the fact that you had this rogue, cold-blooded killer going around hunting humans, then obviously anything you could do to stop those sharks was good,” said Thorrold. “It provided cover for people who simply wanted to go out and kill sharks under the guise of somehow making people safer.”

However, Benchley, who died in 2006, insisted that reports of him regretting the book were untrue. “Regret is a waste of time in a case like this,” he argued. “There’s nothing I can do about it.” He eventually learned that stories revolving around sharks attacking boats and staying in a single area to feed on humans were implausible. As he tells it, things wouldn’t happen that way in real life because the animals have a tendency to spit people out.
