Light as protection: LED lights to protect surfers from sharks

Shark attacks are rare, but the fear of marine predators remains present among many swimmers and surfers. Until now, experts have relied on high-tech solutions, protective nets or special suits to keep sharks away from humans. A surprisingly simple method could now also be effective: LED lights on surfboards. They are intended to deter predatory fish and thus reduce the risk of attacks.
