This is the first study to look at cases of misidentification “from the perspective of the great white shark,” the lead author said. Laura Ryan, biologist at Macquarie University in Australia Sydney.
Last year, however, fewer than 60 shark attacks on humans were counted worldwide. According to the study, these are fueling attack However, there is a “disproportionate” level of fear, as little is known about the behavior of sharks.
