 Great White Sharks

Blood in the water can excite these sharks into a feeding frenzy, where they'll use all 3,000 of their teeth to bite anything that moves. We must say, though, that for all their ferociousness, human deaths from shark attacks are rare. In 2014, there were 72 unprovoked shark attacks on humans worldwide, and three deaths.
