20. Great White Shark

These mythical predators take their time when on the hunt. Following the initial bite, they usually make you bleed out before going in for the kill. In contrast to popular belief, however, these massive animals aren’t man-eaters per se. Rather, a shark will sampling just about anything. They have been known to take bites out of buoys, ships, surfboards, people, pretty much anything that floats. If a bite from their massive jaws draws blood, then they may just go in for more.
