Abstract—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 lateral-
ities of many fish responses remain unclear. It is concluded that, to understand the causes of laterality, it is nec-
essary to study simultaneously its relation to different morphofunctional features in the same specimens.
