The probability of dying bitten by a shark is lower than that of a ray. And there are 100 times fewer possibilities than to receive the bite of another person, according to experts. However, the shark's own image generates fear, since it is very skillful to swim and die.

The University of Florida has investigated shark bite. It is not easy to take sharks to the laboratory, so biologists have invented a curious methodology for the study. Sharks have been rolled with a high-speed camera at 500 frames per second. In addition, sensors have been placed in the shark muscles of the size of the hairs. The combination of both techniques has sought to understand the bite of sharks.

Like humans, the initial hypothesis was that they moved the lower jaw. However, scientists have discovered the opposite. Sharks remove from their site the upper jaw to bite, throw it forward, and put it back in place after the notch.
