Abstract
THE colour of many crustaceans changes in response to variations in the illumination and colour of their surroundings. These changes are brought about by the movement of pigment granules within special epidermal cells or chromatophores, and are controlled by substances liberated by neuro-secretory cells1–3. So far, however, no substance or substances responsible for the movement has been isolated in a pure form, although the preparation of extracts of enhanced activity has been reported by many authors4,5.
