Simple Solution Drives Great White Shark Away from Surfboard

mossel bay, south africa - Scientists in South Africa have discovered a simple solution to reduce the number of shark attacks on surfers.

In Mossel Bay, South Africa, where Great White Sharks are commonly found, scientists have attached LED strips resembling seals (a key prey of sharks) to the undersides of surfboards and dragged them around. The results were astonishing: the powerful sharks, which can grow up to six meters long, were simply deterred by the flickering lights underwater.

The researchers, who published their findings in the journal Current Biology, suspect that the often poorly sighted sharks were blinded by the light, making it difficult for them to assess their prey accurately. The brighter the light, the lower the chance of an attack. The results are remarkable because it was previously believed that (predatory) fish are often attracted to light.

Scientists believe that most attacks on humans are mistakes made by Great White and other sharks. They 'think' they are catching a seal.

It is hoped that not only the Great White Shark, but also other species that occasionally grab a kayaker or surfer, will now stay away. Such as the maximum 3.50-meter long bull shark that also appears in freshwater. Or the Tiger Shark (up to 5.5 meters).

In 2023, 69 shark attacks on surfers were recorded. Most of them in the US, Australia, and South Africa. Ten were fatal. So, the chances of surviving an attack are currently greater.

The researchers hope to quickly bring the ideal light strip to the market.
