| Abstract | Abstract Marine toads ( Bufo marinus ) were tested for their preferences between pairs of small stimuli that were presented simultaneously on opposite sides of the body. In agreement with an earlier study of B. bufo , we found that elongation of prey along the axis of movement facilitates prey catching by B. marinus . This effect is significantly stronger for black stimuli than for white objects of the same size. Contrary to results reported for B. bufo , where double stimuli produced only inhibitory interactions, facilitation effects were found with nearby small objects. However, inhibitory effects were observed when larger stimuli were used. As a possible correlate of mutual inhibitory interactions among rival stimuli we also found via film analysis that toads strike mainly at the leading object when stimuli travel orthogonally to the toad's optic axis. These various data are considered in the light of neuro-physiological interpretations. |
