When Peter Benchley wrote his novel Jaws, which made great white sharks into scary monsters forever, he drew inspiration from the Jersey Shore in the summer of 1916. It was a very hot summer, and throngs of tourists went to the beaches to cool off. It was also the summer that sharks killed four people and badly injured a fifth in New Jersey. Three of those attacks came on the same day! The carnage led to a panic, and people petition for the extermination of sharks. Sharks weren't considered much of a threat before 1916, but their reputation changed overnight.
Could the attacks have come from the same shark? Armed crews went out in boats to kill as many sharks as possible, of all species. One great white was found with human remains in its gut. Some experts thought that the killer shark(s) would more likely have been bull sharks, since they venture into freshwater, and two of the attacks occurred in an inland creek. Some thought that the activities of German U-boats was to blame, causing sharks to develop a taste for humans after devouring the war dead. Others thought that a sea turtle might be the actual culprit. Read about the summer that turned sharks into enemies at Amusing Planet.
