Attacks fell for the third consecutive year to 57 unprovoked bites worldwide in 2020, compared with 64 in 2019 and 66 in 2018. The five-year global average fell to 80 incidents annually.
The increase in fatalities does not indicate a trend, said Gavin Naylor, director of the Florida Museum of Natural History’s shark research program.
“We expect some year-to-year variability in bite numbers and fatalities. One year does not make a trend,” he said in a statement. “2020’s total bite count is extremely low, and long-term data show the number of fatal bites is decreasing over time.”
Florida, with 1,350 miles of coastline and a vibrant surfing community, continued to lead the number of unprovoked attacks, with 16 bites making up for 48 percent of the U.S. total and 28 percent of incidents worldwide, the survey showed. Still, unprovoked bites in Florida were nearly half of the state’s five-year annual average of 30, and less than the 21 attacks in 2019 and 31 in 2018.
Researchers say the coronavirus pandemic may have influenced the number of bites considering lockdown measures and a sharp drop in tourism kept people away from beaches. The challenges of getting data during the pandemic may have also played a role in the drop in attacks.
“While a certain number of cases remain unconfirmed and unclassified each year, this situation was exacerbated in 2020,” said Tyler Bowling, the Shark Attack File manager.
As law enforcement, medical examiners and health-care workers focused on responding to covid-19 cases, some incidents may have not been fully investigated or determined to have been shark attacks.
Bowling is still working to confirm 16 reported bites and classify an additional six confirmed bites as unprovoked or provoked. In 2019, nine incidents weren’t confirmed.
