Shark AttackS Worldwide, there are about 70-100 shark attacks annually, resulting in about 5-15 deaths. Most attacks occur in nearshore waters, typically inshore of a sandbar or between sandbars where sharks feed and can become trapped at low tide. There are three major types of unprovoked shark attacks. The most common are “hit and run” attacks. These typically occur in the surf zone where swimmers and surfers are. The victim rarely sees its attacker, and the shark does not return after inflicting a bite or slash wound. Usually these are cases of mistaken identity that occur under conditions of poor water visibility, breaking surf and strong current conditions. The second and third most common attacks are the “bump and bite” attacks and “sneak” attacks. These result in greater injuries and more fatalities. These types of attacks usually involve divers or swimmers in deeper waters, but also have occurred in nearshore shallows in some areas of the world. “Bump and bite” attacks are characterized by the shark circling and often bumping Caribbean reef sharks circling sailors the victim prior to the attack. In the “sneak” attack the shark attacks without warning. In both cases, the shark attacks repeatedly and multiple bites are sustained. The great white, oceanic whitetip, tiger and bull sharks are resposible for most attacks on people. 1916 New Jersey Shark Attacks; The Worst In U.S. History Along the coast of New Jersey between July 1 and July 12, 1916, four people were killed and one injured. It is not known which shark species was responsible for the attacks, but the great white and bull shark were most frequently blamed. The attacks caused a local and national reaction that led to shark hunts aimed at eradicating the “man-eating” sharks and protecting New Jersey’s seaside economies and communities. Resort towns enclosed their public beaches with steel nets to protect swimmers. The New Jersey attacks immediately entered into American pop culture, where sharks became cartoons in editorials representing danger. The attacks inspired Peter Benchley’s novel “Jaws” in 1974, and Steven Spielberg’s fearsome film by the same name in 1975.
