![]() ![]() The next step would be to find out if predators have evolved to wear these patterns specifically to fool their prey, and if motion dazzle camouflage really benefits organisms in the real world, he said. Nevertheless, the study is the first to demonstrate conclusively that motion dazzle works, Santer said. The studies on human perception of motion dazzle all focused on sideways motion, not an object coming toward the viewer, he said. Lots of animals, including mammals, birds and fish, have looming-detection neurons, Santer said, but whether motion dazzle would fool them too is still unknown.

The neural activity peaks later and at a lower rate in response to the motion dazzle (the patterned squares), Santer said. The confusing, oppositional signals cause the visual neuron to respond more weakly than it otherwise would. "It causes these two opposite stimuli on the eye that antagonize one another," Santer told LiveScience. When a loom-detecting neuron fires, it triggers flying locusts to leap or to swerve out of the way.Äazzle camouflage should mask motion, so if the camouflage really works, it should keep this neuron from working at its best, Santer reasoned. Looming is an important motion to detect if you're a locust, as it could indicate that a predator is headed your way, ready to devour you whole. ![]() To figure out whether dazzle camouflage really exists, Santer turned to an organism he knows well: the locust, which is equipped with specialized vision neurons that respond to looming objects. "The actual evidence that the phenomenon really exists has been a bit sketchy," said Roger Santer, a zoologist at Aberystwyth University in the United Kingdom. Despite the widespread use, nobody knew for sure whether razzle-dazzle camouflage worked, and computer-based studies on humans have yielded mixed results. During World War I, the British and United States Navies adopted dazzle camouflage on their warships, resulting in "razzle-dazzle" vessels that looked like the brainchildren of Picasso. ![]()
