Shark Attacks: Despite the fear of Great White Sharks, at least in part generated by Steven Spielberg's 1975 movie, Jaws, Great White Sharks do not target humans as prey. Most attacks are attributed to mistaken identity. Sharks can easily mistake humans for seals. Many human injuries caused by Great White Sharks are cases of test-biting. If a shark is unsure about a floating object, it often gives it a test bite to determine what kind of object it is. While such bites do little damage to buoys and other objects, they obviously can inflict serious damage on the human body.
