A shark attack is an attack on a human by a shark. Every year around 75 attacks are reported worldwide. Despite their relative rarity, many people fear shark attacks after occasional serial attacks, such as the Jersey Shore shark attacks of 1916, and horror fiction and films such as the Jaws series. Out of more than 480 shark species, only three are responsible for two-digit number of fatal unprovoked attacks on humans: the great white, tiger and bull; however, the oceanic whitetip has probably killed many more castaways, not recorded in the statistics
Contrary to popular belief, only a few sharks are dangerous to humans. Out of more than 480 shark species, only three are responsible for two-digit number of fatal unprovoked attacks on humans: the great white, tiger and bull;[1] however, the oceanic whitetip has probably killed many more castaways, not recorded in the statistics.[2] These sharks, being large, powerful predators, may sometimes attack and kill people; however, they have all been filmed in open water by unprotected divers.[23][24] The 2010 French film Oceans shows footage of humans swimming next to sharks in the ocean. It is possible that the sharks are able to sense the presence of unnatural elements on or about the divers, such as polyurethane diving suits and air tanks, which may lead them to accept temporary outsiders as more of a curiosity than prey. Uncostumed humans, however, present fleshy skin.

Provoked attacks occur when a human touches a shark, pokes it, teases it, spears, hooks, or nets it, or otherwise aggravates/provokes it in a certain manner. Incidents that occur outside of a shark’s natural habitat, e.g., aquariums and research holding-pens, are considered provoked, as are all incidents involving captured sharks. Sometimes humans inadvertently “provoke” an attack, such as when a surfer accidentally hits a shark with a surf board.
Unprovoked attacks are initiated by the shark—they occur in a shark’s natural habitat on a live human and without human provocation.There are three subcategories of unprovoked attack:

Hit-and-run attack – Usually non-fatal, the shark bites and then leaves; most victims do not see the shark. This is the most common type of attack and typically occurs in the surf zone or in murky water. Most hit-and-run attacks are believed to be the result of mistaken identity.
Sneak attack – The victim will not usually see the shark, and may sustain multiple deep bites. This is the most fatal kind of attack and is not believed to be the result of mistaken identity.
Bump-and-bite attack – The shark circles and bumps the victim before biting. Repeated bites are not uncommon and can be severe or fatal. Bump-and-bite attacks are not believed to be the result of mistaken identity.
An incident occurred in 2011 when a 3-meter long great white shark jumped onto a 7-person research vessel off Seal Island, South Africa. The crew were undertaking a population study using sardines as bait, and the incident was judged to be an accident
