Psycho Shark

In Japan Scientists for the last couple of decades have been doing research on Megalodon the Ancestor to that of Charcaradon Carcarius aka The Great White Shark. It turns out that they are having success and have been raising one that was cloned from a Megalodon's DNA and the DNA was genetically programmed into the eggs of a Great White Shark Female and that egg was placed in a artificial womb where it was allowed to grow then when it was born it was placed in a extraordinarily oversized tank. However the Shark has found a way to escape from the tank and get into the Sea of Japan. Now being a new shark and all it's very hungry and it needs some very real meals!
