The ocean is a dangerous place because there is something lurking in the shadows. A creature that never stops moving and is craving a beach side snack. That's right, we're talking about sharks. These carnivorous ocean swimmers spend a great deal of their time chowing down on fish and various other sea life. But when these vicious animals crave something a little more exotic they may take a bite out of a person who is swimming where they shouldn't. Now all they take is a taste because sharks digestion systems can't really deal with the human ratio of bone to muscle and fat. Just be sure though to keep an eye out for that fin on the beach!
