Great whites are among the biggest and deadliest of the 400 known species of shark.
Together with tiger sharks and bull sharks, they form the so-called Big Three and are responsible for the highest number of attacks on humans.
According to the Florida Museum of Natural History, the three species are big enough to inflict “serious injuries” thanks to their razor-sharp teeth.
The museum said: “The white shark has been credited with more fatal attacks on humans than any other species of shark.
“This is due primarily to its size, power and feeding behaviour.”
