Résumé : Most dinoflagellates have complex life cycles (figures 5, 12), comprising free swarmer cells, non-mobile coccoid forms, and resting cysts (figures 24,25). Many species exhibit bioluminescence (’blue tears’ figures 15-19) and may produce toxins that accumulate through the food chain, manifesting as shellfish poisoning syndromes (Note 2). Most free-living forms are mixotrophic, with capacity of photosynthesis and obtaining nutrients from their environment. Symbiotic dinoflagellates form a symbiotic relationship with corals; cessation of the two-way operatives will lead to coral bleaching (figures 11-14), and demise of our coral reef ecosystems. The dinoflagellate swarmer cells have two flagella which perform a whirling movement (Greek = dino) (figures 1-4), enabling them to conduct vertical migration between different water bodies to access better nutrient patches. Many species are counter-intuitively sensitive to turbulence, and tend to aggregate in stagnant water, or as in the case of symbiotic dinoflagellates habituated inside their coral hosts. Vast &#8217;blooms&#8217; of dinoflagellates often end as waters shallow, or they transform into &#8217;resting&#8217; cysts that sink to benthic sediments to await more favourable conditions. This bloom-to-cyst life cycle is adopted as the storyline in this ScienceArt Commune, focusing on the concept of &#8217;self-one&#8217; and &#8217;farewell my concubine&#8217; (figure 6). Individuals within a bloom (Figure 18), despite appearances, are not identical, as different parts within the water body is different. Some cells are closer to the surface with higher irradiance and exposure, while others are screened by the bloom and face potential anaerobic conditions near the bottom. The moving average(s) are composed of different self-ones, as well as perceived self-images, perhaps photo-acclimatised and changing in photopigment composition. Fare-well con&nbsp;combine the different life cycle stages, they are all the same dinoflagellates, with different epigenetics and transcriptomes.
