Survival after an unprovoked shark bite is high, with 82% of global incidents ending with the victim living, yet the difference between a grazing scrape and a life changing injury can come down to minutes. The International Shark Attack File recorded 69 unprovoked shark bites worldwide, a jump of 40% from the prior year, and the same dataset also tracks everything from 25% bacterial infection rates to 70% of fatalities tied to torso or throat wounds.

Fatality and Injury Details Interpretation
While the dramatic odds of a fatal shark bite are reassuringly lower than your chance of being killed by a falling coconut, the raw statistics reveal a serious game of biological Russian roulette where survival hinges on avoiding a direct hit to the torso and having a tourniquet and a helicopter nearby.

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.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
