Dodge die Art als Lingulodinium polyedrum in die Gattung Lingulodinium. Lingulodinium polyedrum is an armoured, marine, bioluminescent dinoflagellate species. The blue light is a result of a luciferase enzyme (like firefly luciferase, but the enzyme in L. polyedrum shares no similarity with that of the firefly enzyme). Authors Liyun Liu and Woody Hastings Dinoflagellates are an unusual group of organisms in many respects, including a large amount of DNA per cell (up to 40x that of the human) and the ancestral diversity of their genes. Lingulodinium polyedrum had the largest slope, 5.1 1.3, with the response proportion changing by a factor of 1000 over the range of wall shear stresses examined. Die Art wurde 1883 als Gonyaulax polyedra von Friedrich von Stein beschrieben. The red tide that has lit San Diego for several weeks is ending in a microscopic bloodbath.
