In rare cases, prey capture attempts were also triggered by hydrodynamic flow fields generated by a fish swimming close below the water surface. Visual stimuli alone were not used for identification and localization of prey. Concentric water surface waves are produced whenever a fish, frog, or tadpole contacts the water… CONTINUE READING
