Autogamy in Para- mecium aurelia. Persistent Rhythms in Gonyautax Polyhedra: How Organisms Tell Time Gonyaulax is a marine microorganism. It is single-celled, built like a protozoan, but contains chlorophyll and is capable of photosynthesis. It normally grows at the surface of the sea and can also be cultivated in the laboratory. In addition to being photosynthetic, Gonyaulax can luminesce (, like fireflies and other insects, crustaceae, some molds, bacteria, and algae, it can operate biochemical reactions that release energy in the form of light instead of the more usual heat). It is one of the organisms respon- sible for the brilliant displays of "phosphorescence" seen at night on ocean waves. At least three important functions—photosynthesis, luminescence, and cell division—are carried out in a regular rhythm keyed to the marine habitat of the organism. Gonyaulax photosynthesizes by day, luminesces by night, and reproduces just before dawn. 18.
