| Description: | The video shows examples of the variety and wealth of forms exhibited by the dinoflagellates. It elucidates the modes of locomotion and nutrition evolved by individual species. In the stricter sense, dinoflagellates belong neither to the plant nor the animal kingdom. Unicells like Gonyaulax polyedra or Pyrocystis noctiluca exhibit various types of circadian rhythmicity: the vertical migration of cells, the intracellular distribution of chloroplasts and the diurnal rhythmicity of bioluminescence are presented. The origination of light flashes in unicells was filmed in Pyrocystis noctiluca with a highly specialized light sensitive camera. Light cinemicrography is augemented by shots in fluorescence microscopy. |
