The International Shark Attack File (ISAF) defines unprovoked attacks as "incidents where an attack on a live human occurs in the shark’s natural habitat with no human provocation of the shark" and provoked attacks as incidents where "a human initiates interaction with a shark in some way. These include instances when divers are bitten after harassing or trying to touch sharks, attacks on spearfishers, attacks on people attempting to feed sharks, bites occurring while unhooking or removing a shark from a fishing net, etc." [src.]

 
The International Shark Attack File (est. 1958) is housed at the Florida Museum of Natural History and is the only scientifically-generated database that documents and monitors shark attacks on a global basis.
