Question

why shark eating humans

Answer 1

bcz its an carnivorous species so it eats human too........

Answer 2

Even if the food-human link is indirect, it likely explains most shark attacks in general. The National Oceanic and Atmospheric Administration (NOAA) explains that sharks do not normally hunt humans, but if they do attack, it is usually a case of mistaken identity. Assuming a large, predatory shark has not been exposed to human flesh before, it is probably used to biting into thick-tissued, fatty sea lions, seals and similar-bodied prey. Sometimes sharks will investigate potential food items by taking a taste.
