Surfboard Lights Could Help Deter Sharks, but Don't Rely Solely on Them for Safety

Australian researchers have made a significant breakthrough in shark deterrence by discovering that wrapping seal-shaped decoys in bright, horizontally striped LED lights can effectively repel great white sharks. This innovative approach stems from the understanding that sharks rely on seeing the dark outlines of their prey against the sunlit water. The study, led by Nathan Hart of Macquarie University, suggests that the lights disrupt the typical silhouette of a seal, making it less recognizable to sharks. The researchers plan to further test this technology by installing similar lighting patterns on surfboards to enhance safety for ocean-goers. While this study presents a promising advancement in shark repellent technology, experts caution that sharks also utilize other senses, such as smell and vibration, when hunting. Overall, the research aims to create a safer environment for activities like surfing, despite the rarity of shark attacks.
