BEIJING, Sept. 4 (Xinhuanet) -- A digital study of a great white shark's biting strength will likely reveal it's not the jaw force that counts, it's the way prey is shaken from side to side while grasped in the shark's razor-sharp teeth, researchers say.

Daniel Huber, a biologist at the University of Tampa in Florida, examined an eight-foot (2.4-meter) great white shark that had died after becoming entangled in nets off the coast of Australia. Huber and his colleagues dissected the shark's head and took several measurements, including the size and placement of the jaw muscles.

"We are figuring out in three dimensions the leverage of all of these jaw muscles," Huber told Live Science. The jaws work like a set of pliers, where pliers with long handles would let you grab an item with more force than pliers with short handles.

The researchers are developing a 3-D digital recreation of the shark from the data and a computer simulation of a full-force bite. They will compare the final force estimate with those from tiger and bull sharks, which, along with the great white, are responsible for most shark attacks on humans.

"The white has the narrowest head of the three, so it has less space for jaw muscles," Huber said. "Consequently, we're expecting that it will have a lower bite force on a pound-for-pound basis."

But great whites would still top the charts as savviest hunters and most adept at capturing prey.

"Much of the damage inflicted by white sharks is due to their teeth, and not necessarily to the force," Huber said.
