Lingulodinium polyedra are easily visible under 100x magnification (use the 10x or "scanning" objective on most compound microscopes) and their scintillons luminescence in response to surface tension and acidity. The Unique Human Health Effects of Blue Light. While it is universally accepted that plankton continually experience a dynamic fluid environment, their sensitivity to the features of the surrounding flow field at the relevant length and time scales of the organism is poorly characterized. Order Gonyaulacales Taylor, 1980. Members of Lingulodinium polyedra, a species of single-celled dinoflagellates, appear to be a reddish-brown during the day and then emit light by way of bioluminescence at night. "The first is that it acts as aposematic colouration, a warning to potential grazers that the cell is toxic or harmful to the grazer in some way. Related topics. Cell Press. Papers overview.

Lingulodinium polyedrum (Stein) Dodge 1989. Now, researchers reporting in Current Biology on June 17 have found that for one dinoflagellate species (Lingulodinium polyedra), this bioluminescence is also a defense mechanism that helps them ward off the copepod grazers that would like to eat them. Two regions of the mRNA were found using an antibody versus luciferase and a cDNA expression library, and the full mRNA was found by Northern hybridization. "Dinoflagellate plankton glow so that their predators won't eat them." Through a combination of high-speed and low-light sensitive videos, the researchers, including Prevett, Erik Selander, and their collaborators at the Technical University of Denmark, revealed that the bioluminescent cells flash upon contact with the copepod grazer.
