Using LED lighting on the underside of surfboards or kayaks could deter great white shark attacks, new research suggests. An Australian-led study found lighting disrupted the ability of great whites to see silhouettes against the sunlight above, reducing the rate at which the sharks followed and attacked seal-shaped decoys. ‘We think this tells us a lot about how sharks see the world and how they detect and target their prey,’ Macquarie University’s Prof Nathan Hart says. ‘But it also potentially gives us an insight in to how we can develop a non-lethal shark deterrent.’
