All About Sharks – Do All Sharks Attack Humans?
In spite of all the movies about shark attacks, more people die from bee stings than shark attacks. The great white shark isn't usually the culprit. More people get attacked by bull sharks that live in shallow waters. Only about one in fifteen shark species will attack a human, but they usually don't like the taste. Sharks have great night vision and a superior sense of smell. They can detect a beating heart. Sharks are carnivores ranging in size from seven inches to fifty feet.
