Streamlined fish, such as salmon, undulate the caudal portions of their bodies. Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
Both behavioral and physiological optomotor responses have distinct tuning curves for the temporal, spatial and contrast structure of moving images. [ 5 ] [ 18 ] [ 19 ] The magnitude and time-course of the optomotor response to optic flow depends on the temporal frequency of image motion, the spatial period of the display pattern, the periodic ...
