LED lights on underside of surfboards may deter great white shark attacks

Australian-led study using seal-shaped decoys finds lighting disrupts ability of predators to see silhouettes against sunlight above

Using LED lighting on the underside of surfboards or kayaks could deter great white shark attacks, new research suggests.

In an Australian-led study using seal-shaped decoys, underside lighting disrupted the ability of great whites to see silhouettes against the sunlight above, reducing the rates at which the sharks followed and attacked the artificial prey. The brighter the lights, the more effective the deterrent was.
