Abstract: The chiton Stenoplax heathiana was shown to respond to both the onset (on-response) and the removal (off-response) of the light stimulus. In both cases the response consisted of a slight clamp-down to the substrate, preseumably to help maintain the animals grip on the substrate. If the animal is light adapted, the magnitude of the off-response increases while that of the on-response decreases. These responses were shown to be indiependent of the wavelength of the light used to ligh adapt the animal, which indicates that the differences did not result from stimulating two separate visual pigments. Thus, while this effect has clear adaptive signific
