SummaryThe introduction of game-theoretical thinking into evolutionary biology has laid the groundwork for a heuristic view of animal behaviour in which individuals employ ‘strategies’ — rules that instruct them how to behave in a given circumstance to maximize relative fitness. [...] Key MethodHere we describe a study in which guppies were tested in multiple predator inspection trials. An individual was tested with its mirror images as well as a series of live conspecifics. Results indicate that guppies are…Expand
