Predation history has no effect on lateralized behavior in Brachyrhaphis rhabdophora
evolutionary ecology, predation, lateralized behavior, laterality, livebearers
Lateralized behavior is common in nature: sea turtles preferentially use a dominant flipper to swim, passerine birds display footedness when catching mealworms, and humans display a bias in head-turning during kissing. Several fish species even prefer to use one eye over the other when viewing certain stimuli.
Predation is an environmental factor known to affect behavior in a variety of organisms (e.g., mule deer, water striders, and some species of Poeciliid fishes). Mosquitofish males, for example, preferentially use one eye to evaluate mates and predators, but show no bias for other males or an empty tank
