LED Camouflage Could Help Prevent Great White Shark Encounters

A recent study published in Current Biology reveals that strategically using LED lights can disrupt great white sharks’ ability to see silhouettes, potentially reducing the risk of shark attacks on humans. Conducted by researchers in Australia, the study involved towing seal-shaped decoys with LED lights in Mossel Bay, South Africa, demonstrating that the lights altered sharks’ perception of the decoys, making them less likely to recognize them as prey. Lead researcher Dr. Laura Ryan explained that since great whites struggle with visual clarity, particularly in differentiating between seals and surfers, the LED-enhanced decoys can help mitigate mistaken identities that lead to attacks. The study found that horizontal LED strips were most effective in masking the silhouette of a seal. Further research is planned to test these techniques with stationary decoys resembling surfers. Though rare, the study highlights that most unprovoked shark attacks occur in aquatic sports contexts, primarily involving great whites.
