Sharks Have Surprisingly Weak Bites
Researchers announced on Tuesday that sharks have surprisingly weak bites for their mass and can decimate their prey simply because of their strong teeth.
Their investigations of their jaws indicate that lions or tigers are much stronger when it comes to jaw force, but sharks win frequently in the water due to their extensive jaw size.
"Pound for pound, sharks don't bite all that hard," said Daniel Huber of the University of Tampa in Florida, leader of the investigation.
Huber and his researchers had difficulty amassing information for their investigation, "due to the experimental intractability of these animals," they laughed at in their findings, published in Physiological and Biochemical Zoology.
"The vast majority of the data that went into this study was biomechanical models," Huber noted.
The researchers calculated the bites of diminutive sharks, like the sand shark, and investigated bigger sharks by tranquilizing them and stimulating their jaw muscles.
Their deduction is that sharks inflict the majority of their harm because their teeth incredibly pointed and they have huge jaws.
"Our analyses show that large sharks do not bite hard for their body size, but they generally have larger heads," they stated.
Most sharks employ a sawing action to rip through their victims, noted Huber. A 20-foot great white shark can "bite through anything that you come across," Huber added.
