"There was a big gap in the literature on this topic", says João Vitor de Alcantara Viana, a behavioral ecologist at the State University of Campinas in Brazil, who led an investigation into which strategies work best. Though scientists have spent more than a century observing and studying the camouflage tactics animals use to deter detection by predators, few of those efforts have compared the effectiveness of different concealment strategies. In general, the ecologists report in the Proceedings of the Royal Society B: Biological Sciences, predators must spend about 60 percent more time finding camouflaged prey than noncamou-flaged prey.
