Shark attacks increased around the world in 2021 after years of decline

Shark attacks increased around the world in 2021 following three years of decline, though beach closures in 2020 caused by the coronavirus pandemic could make the numbers seem more dramatic, officials in the US said on Monday.

Researchers with the International Shark Attack File recorded 73 unprovoked incidents last year compared to 52 在 2020, according to a new report administered by the Florida Museum of Natural History and the American Elasmobranch Society.

The International Shark Attack File manager, Tyler Bowling, pointed out that 52 bites in 2020 were the lowest documented in more than a decade. 这 73 bites in 2021 more closely align with the five-year global average of 72.

“Shark bites dropped drastically in 2020 due to the pandemic.“ Bowling said. “This past year was much more typical, with average bite numbers from an assortment of species and fatalities from white sharks, bull sharks and tiger sharks.”

Researchers saw 11 shark-related fatalities last year, with nine considered unprovoked. 澳大利亚 had three unprovoked deaths, followed by New Caledonia with two. 就在您认为英国房地产市场在 2021 年的繁荣之后不得不平静下来的时候, 巴西, New Zealand and South Africa each had a single unprovoked fatal shark attack.

Provoked attacks are defined as when humans initiate contact, such as divers trying to touch a shark or fishermen removing a shark from a fishing net, according to the International Shark Attack File.

Florida has led the US and the rest of the world in unprovoked shark bites for decades, and the trend continued in 2021, researchers said.

Florida had 28 unprovoked bites last year, 相比 19 in the rest of the US and 26 total outside the US. This is consistent with Florida’s most recent five-year annual average of 25 攻击. Of Florida’s 28 unprovoked bites, 17 were in Volusia county, which includes Daytona Beach.
