Abstract: Light responses in six species of the genus Acmaea (Acmaea scabra, A. digitalis, A. scutum, A. pelta, A. asmi, and A. limatula) were investigated. Acmaea limatula showed the strongest responses to light. All responses exhibited were negative phototaxes. Experiments varying color and intensity indicate the eye spots of A. limatula are important as photoreceptors in colors blue, green, and red at high and low intensities. There is at least one other photreceptor and pigment, which is functional only in blue light at higher intensities. Other observations showed no correlations between size and response to light.
