The shark's eyesight is pretty good.
A photographer has demonstrated how great white sharks will chase his drone’s shadow in much the same way a cat will chase a laser pointer.In the above video, Gauna says he is often asked whether the sharks he is filming can see or sense the drone above them. So, he wanted to test out whether they noticed them by flying his drone’s shadow close to a great white shark.
“It quickly became evident that the shark’s vision is very precise,” says Gauna. “For me, it demonstrates that sharks react to the drone’s shadow instead of the drone itself and it gives me information for where to fly to minimize interference.” “The shark seems to be reacting to shadows when they are beside it, behind it, and in front of it. It really raises questions about how good their vision is,” he says.
