Laterality of behavioral responses in bony fishes: Inheritance, adaptive importance, and morphofunctional correlates

Current data on the relation of locomotory responses laterality to taxonomy and mode of life in fish, as well as to asymmetry of CNS, sensory, and somatic organs, are examined. Although the correlations of behavioral laterality with some of the abovementioned features are already found, the causes inducing lateralities of many fish responses remain unclear. It is concluded that, to understand the causes of laterality, it is necessary to study simultaneously its relation to different morphofunctional features in the same specimens.
