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.

Interpretation
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.

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.
