2017 "average year" for unprovoked shark attacks

In 2017, there had been 88 reported unprovoked shark attacks worldwide. Although this figure is an increase from the most recent five-year annual average of 83, it is pretty much considered to be an "average year", according to Lindsay French, who manages the University of Florida International Shark Attack File (ISAF).

The ISAF is the world's only scientifically documented, comprehensive database of all known shark attacks.
