Two-headed Shark

So a two headed shark was found sometime after one of the devastating oil spills in the Gulf of Mexico. http://www.guardian.co.uk/environment/video/2013/mar/28/two-headed-shark-video Is this Darwin's theory at work, proof that Cerberus and Dante's hell-beast are more than fiction, or clear evidence that our societal devil may care attitude toward preserving nature could have its repercussions? Either way, I think Spielberg should do a remake of Jaws 2 based around this new find.
