Thought the mighty megalodon shark was extinct? Think again! There's one more specimen alive today in the ocean, and he's just a little pup right now. So tiny, so helpless, no bigger than the size of a goldfish. And the only way for him to get bigger is to eat every fish that he can see! But be careful! He can only eat the fish that are smaller than him (in length). If they are even an inch longer, they can turn the tide and gobble him up! Now the megalodon may be considered an "invasive" species due to being more or less extinct for 3.6 million years, but don't let that bother ya!
