Shark attacks are rare, but confirmed records show clear geographic differences in where and to whom incidents occur. On this page, you’ll see how patterns vary across the US (notably Florida), Australia, South Africa, and Hawaii, plus which species are most often implicated. We also track recent unprovoked-bite trends and review the typical victim demographics and injury outcomes reported in severe cases.
Key Takeaways
