If you are afraid of sharks, be afraid of this one. The Bull Shark (Carcharhinus leucas) kills more people each year than Great White Sharks and Tiger Sharks put together. What makes them so dangerous is that these sharks can live in freshwater and have also been known to hunt in shallow water. The Bull Shark is the shark responsible for the Jersey Shore shark attacks of 1916 along with the great white shark. The attacks inspired the novel Jaws.
