To most of us sharks are the most dangerous fish in the sea and they attack humans. However according to Dr. Clark who has studied the behavior of sharks for 12 years, humans are not normally on a shark’s menu. What do sharks feed on? Mainly fish and other small sea animals. Dr. Clark also found that sharks don’t eat as much as people think. For instance, a 9-foot shark only needs 2 pounds of food a day to keep healthy. But she says sometime sharks starve and the other times they feed themselves with what they have killed.
Around the world there are only about 100 shark attacks on humans each year ten of which prove fatal. But consider this, in the U.S. alone, about 3 million people are bitten by dogs each other. Of these, thirteen people died. "If shark bites you", says Dr. Clark, "The reason is usually because it mistakes you for its natural food." For example, say you when underwater fishing and saw a shark, you could be in trouble. The shark might go for the injured fish you had attacked and take a big bite at you at the same time. If you go into a sharks’ territory and threaten it ,it might try to bite you. because sharks are territorial and tend to guard their territory. Like dogs, they protect the area the think is their own.
