Scientists meticulously dissect a great whit shark to demonstrate how extensively evolution adapted it into an unsurpassed oceanic hunting machine. Previously thought to have a walnut brain, it's actually a huge computer to process the extreme mass of data obtained by its arsenal of super-senses to locate and examine its potential prey, on the move and from great distance: hearing, sight, smell, taste and unique electromagnetic detection. To satisfy its huge caloric need, it normally hunts large, fat prey in cold waters, mainly seals, sometimes even dolphins or wales. It also has special hydrodynamic skin and immense muscles, both for sprint and long distance, an unequaled arsenal of teeth and digestive system with extremely corrosive acid and a stomach it can bring into its mouth.
