Sharks are picky eaters, even if their table manners are terrible. They usually mistake humans for seals or other tasty critters.
Avoid shiny jewelry—it flashes like fish scales. And please, no neon swimsuits that scream “eat me!” in shark language.
If you’re bleeding (even a tiny cut), get out of the water. Sharks can smell blood from a mile away, and they’re not exactly subtle about it.
