What Happened To The Biggest Shark Ever

The shark featured in  JAWS and many other TV shows and movies mysteriously disappeared and nobody knows why.  Also known as Carcharocles megalodon, the megatooth species died about 2.5 million years ago.  Scientists like to equate its sudden death with a change in water temperature in the Atlantic, Pacific, and Indian Oceans (where these sharks could be found).  However, many are in disbelief that a huge man-eating shark could be taken down by a simple change in temperature.
