Home » Sea Sparkle Linked With Dentistry Sea Sparkle Linked With Dentistry Recently, something amazing happened on an Australian beach – an algae called Noctiluca scintillans bloomed in unprecedented volume along the surf. [7] Green tides result from N. scintillans populations having green-pigmented prasinophytes (green algae, subphylum Chlorophyta)[8] living in their vacuoles. That is a characteristic for animals. N. scintillans populations can exhibit high concentrations due to high concentrations of the plankton on which they feed, which are likely due to environmental conditions such as well-mixed, nutrient-rich waters, seasonal circulation, and runoff from agricultural pollution.

N. scintillans does not appear to be toxic, but it feeds voraciously on phytoplankton, and while doing so, it accumulates and excretes high levels of ammonia into the surrounding water. Bloom color partly derives from the pigments of organisms inside the vacuoles of N. scintillans. The bioluminescent algae, commonly called sea sparkle, has delighted locals at Tasmania's Preservation Bay. But it’s not quite. It is typically seen in calm waters. Topic: Conservation, environmental pollution and degradation, environmental impact assessment. N. scintillans can be found widely distributed throughout the world, often along the coast, in estuaries, and shallow areas of the continental shelf that receive plenty of light, which promotes the growth of the phytoplankton that make up a large portion of the N. scintillans diet. These consumed This gives N. scintillans the popular names "sea ghost" or "fire of sea".[5][6]. N. scintillans is a heterotroph that engulfs, by phagocytosis, food which includes plankton, diatoms, other dinoflagellates, fish eggs, and bacteria. N. scintillans produces a string of mucus extending from the tip of the tentacle which then adheres to plankton and ascends rapidly through concentrations of its prey in the water column.
