According to the International Shark Attack File (ISAF) at the University of Florida, ‘Unprovoked bites’ are defined as incidents in which a bite on a live human occurs in the shark’s natural habitat with no human provocation of the shark.

Meanwhile, ‘Provoked bites’ occur when a human initiates interaction with a shark in some way.

The U.S., with Florida’s 16 incidents in the lead, reported the most unprovoked shark attacks in the world last year, according to the document.

Of the 41 U.S. cases, only one ended in death, in Hawaii.

The state accounted for five unprovoked attacks last year, the file says.

Consistent with long-term trends, the U.S. recorded the most unprovoked shark bites in 2022, with 41 confirmed cases. This is lower than the 47 incidents that occurred in the U.S. in 2021. The 41 cases represent 72% of the worldwide total. This is an increase from 2021 when 64% of the worldwide unprovoked bites occurred in the U.S.

In total, unprovoked bites by state were New York (8), California (4), South Carolina (4), Hawaii (5), North Carolina (2) and single incidents in both Texas and Alabama.

In Florida, Volusia County had the most shark bites (7), representing 44% of the state’s total. 

Surfers and those participating in board sports accounted for less incidents (35% of the total cases). Swimmers and waders accounted for the majority of incidents at 43%.
