Predation shapes behavioral lateralization: insights from an adaptive radiation of livebearing fish

Kaj Hulthén, Heinen-Kay Justa Lee, Danielle Schmidt & R. Brian Langerhans
Hemispheric brain lateralization can drive the expression of behavioral asymmetry, or laterality, which varies notably both within and among species. To explain these left–right behavioral asymmetries in animals, predator-mediated selection is often invoked. Recent studies have revealed that a relatively high degree of lateralization correlates positively with traits known to confer survival benefits against predators, including escape performance, multitasking abilities, and group coordination. Yet, we still know comparatively little about 1) how consistently predators shape...
