SYDNEY, Aug. 6 (UPI) -- Australian scientists say they've determined the bite force of a great white shark can reach about 1.8 tons, 20 times greater than a human's bite.
Measuring the bite of a predator like a great white shark might sound like a guaranteed trip to Davy Jones's Locker. .comments .comments-content .loadmore a {

Bite Force of The Great White Shark image. Some elasmobranchs — such as Horn Shark (Heterodontus francisci), the Nurse Shark (Ginglymostoma cirratum), or the Southern stingray (Dasyatis americana) — have very short, heavily calcified jaws relative to the White Shark (Carcharias carcharodon); it would be interesting to know how much bite pressure or force any of these crestiaconts could muster. color: #cccccc; a:visited {

Now, Stephen Wroe from the University of New South Wales has put the great whiteâs skull through a digital crash-test, to work out just how powerful its bite was. }
