According to the researchers’ findings, the risk of mis-surfers being mistaken for animals preyed upon by great white sharks is particularly high.
There are only 60 attacks a year
For the study, video recordings of marine mammals were compared to humans swimming and surfing from the shark’s point of view—that is, from below. From their point of view, the great white shark is “unable to clearly distinguish between humans and pinnipeds,” the authors write.
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.
