Abstract

The step-up photophobic and negative phototactic responses of Stentor coeruleus to visible wavelength light represent two clear examples of the photosensitivity of aneural motile organisms. The former is a stop/reversal response exhibited by the organism as it crosses from the dark (lower light intensity) to the light side (higher light intensity). Figure 1 shows a videomicroscopic recording of the step-up photophobic response exhibited by two stentor cells.
