Images have been floating around the net showing what appears to be the carcass of what definitely has to be the world's biggest snake.
The story circulating with the pictures claims the snake was found in the Red Sea. 
They claimed the snake was over 20 feet tall and as long as 3 ½ school buses...(approx 36 feet)
The age of the beast, taken its considerable size into consideration was estimated to be over 100 years old. (2 audio takes)
Images included pictures of the dead snake on top of some kind of military transport carrier, next to some tanks, being hoisted up by a helicopter among others...
I was intrigued by the images as well as the story. I had my own questions and wanted answers...
 How big can a snake get?
 How long can a snake live?
And last but not least.
