Single sourceFatalities, Injuries, and Prevention Interpretation
Humans, in our eternal quest to splash where we don't belong, have gotten remarkably clever at not being eaten, turning a six-fatality global average into a story of frantic innovation, from drone spies to wetsuit camouflage, all to outsmart an ancient predator that still, quite rudely, prefers to strike in shallow water.

Single sourceGeographic and Regional Distribution Interpretation
While Florida proudly claims the title of ‘Shark Bite Capital of the World’ thanks largely to a few sandy hotspots, the sobering reality emerges that when sharks do attack in places like Reunion Island or parts of Australia and South Africa, the tragic price of a failed sea-level truce tends to be far higher.

Single sourceGlobal Incidence and Trends Interpretation

VerifiedShark Species Involved Interpretation
While the ocean boasts a diverse cast of sharks, the sobering reality is that a handful of species—bull, white, and tiger sharks—account for the majority of serious incidents, often because our favorite swimming spots unfortunately overlap with their murky, fish-rich hunting grounds.
