According to the International Shark Attack Files, there are two types of sharks attacks: provoked attacks and unprovoked attacks. The former are the result of human activities, like spearfishing, that lure sharks to an area; the latter normally occurs when sharks mistake humans for other, far more common kinds of prey, like seals.
