Global Incidence and Trends Interpretation
In the grand theater of human-shark relations, last year's 69 bites—while a noticeable spike—are less a sign of rising shark aggression and more a predictable reflection of our ever-increasing numbers crowding into their ancient neighborhoods.

Regional Distribution Interpretation
While the data confirms that entering the ocean means entering a shark's dining room, the United States—with Florida as its particularly eager host—is, by a significant margin, setting the global table for unprovoked bites.

Species Involved Interpretation
Despite their terrifying reputations, most sharks are like specialized niche chefs—great whites serve up dramatic headlines, bull sharks prefer the crowded Florida buffet, and tiger sharks run the Hawaiian takeout joint, but the real takeaway is that you're far more likely to be nibbled by a blacktip in Volusia County than become the star of a blockbuster oceanic tragedy.
