Great white sharks are the largest predatory sharks on Earth, weighing about 5,000lbs. That doesn't mean they want to eat you. Shark attacks on humans are usually a result of curiosity, and are rarely fatal. Scientists call this "sample biting," because once a shark figures out that a human isn't food, they usually lost interest. When a great white does kill a human, the death is more often due to blood loss from the bite, rather than a full-fledged attack.
