The shark is the ultimate killing machine. It does three things: swim, eat, reproduce. It has a conveyor belt of teeth which basically makes it a large, living, underwater chainsaw. The only thing that would make it deadlier is to make it bigger. Enter the Megalodon, which was just like out great white sharks, except three times larger. I used the past tense, but it has been scientifically proven that there is a chance they are still alive and patrolling the deepest parts of our ocean. This week we explore the depths and teach you how to survive a Megalodon encounter.
