Mediterranean snakelocks sea anemone, Anemonia sulcata. Above photographed with daylight and bellow showing fluorescent colours photographed under special blue or ultraviolet light and filter. Many anemones and corals are intensely fluorescent under certain light wavelengths. Shallow water reef-building fluorescent corals seem to be more resistant to coral bleaching than other corals, and the higher the density of fluorescent pigments, the more likely to resist. This enables them to better protect the zooxanthellae that help sustain them. The pigments that fluoresce are photoproteins, and a current theory is that this acts as a type of sunscreen that prevents too much UV light damaging the zooxanthallae. These corals have the photoproteins above the zooxanthallae to protect them. Corals that grow in deeper water, where light is scarce, are using fluorescence to absorb UV light and reflect it back to the zooxanthallae to give them more light to turn into nutrients. These corals have the photoproteins below the zooxanthallae to reflect it back. Photographed in aquarium. Portugal

Beaucoup d'anémones et de coraux sont intensément fluorescents sous certaines longueurs d'ondes lumineuses. Les coraux fluorescents qui construisent des récifs en eau peu profonde semblent être plus résistants au blanchiment des coraux que les autres coraux, et plus la densité de pigments fluorescents est élevée, plus ils ont de chances de résister. Cela leur permet de mieux protéger les zooxanthelles qui les aident à se maintenir. Les pigments qui fluorescent sont des photoprotéines, et une théorie actuelle veut que ce soit un type d'écran solaire qui empêche une trop grande quantité de rayons ultraviolets d’endommager les zooxanthallae. Ces coraux ont les photoprotéines au-dessus des zooxanthallae pour les protéger. Les coraux qui se développent dans des eaux plus profondes, où la lumière est rare, utilisent la fluorescence pour absorber la lumière ultraviolette et la restituer aux zooxanthallae afin de leur donner plus de lumière pour se transformer en nutriments. Les photoprotéines de ces coraux se situent sous le zooxanthallae pour le refléter.
