[G. dinos, whirling, + L. flagellum, a whip]

n.
Any of numerous minute, chiefly marine protists of the phylum Dinoflagellata, characteristically having two flagella and a cellulose covering and forming one of the chief constituents of plankton. They include bioluminescent species, photosynthetic species, and species that produce red tide.

dinoflagellate

Hegaret and Wikfors (2005a) also reported an increase in granulocyte percentage in eastern oyster Crassostrea virginica (Gmelin, 1791), and northern bay scallops Argopecten irradians (Lamarck, 1819) exposed to a toxic dinoflagellate after 7 days of exposure but after an initial boost in hyalinocytes during the first 2 days of exposure.
The literature had no guidance for storms, but we expected the lag time for the effect of storms (18 months) to be longer than that of SST because the proposed mechanism adds habitat destruction and recolonization by toxic dinoflagellates to the SST timeline.
As for dinoflagellates and chlorophyta, the maximum recommended levels of density should be, respectively, 500 and 50,000 cel.
Such temperatures in the high Arctic are supported by biogeographical data, such as the abundant occurrence of subtropical dinoflagellates (Sluijs et al.
