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

any of a group of unicellular biflagellate aquatic organisms forming a constitutent of plankton now normally placed in the division Pyrrhophyta. They can be regarded as an order of protozoans (Dinoflagellata) or a class of algae (Dinophyceae).
