A study into the photophysiology, growth and migration of Ceratium hirundinella in Chaffey Reservoir in subtropical northern New South Wales, Australia, revealed that a proportion of cells formed subsurface accumulations at depths that optimized light intensity (212–552 μmol photons m –2 s –1) for photosynthesis and cell growth. Ceratium tripos (O.F.M.) Nitzsch was isolated from samples taken from the north end of the Cape Cod Canal, Bourne, Massachusetts in June, 1970. Cultures were grown in f/2 enriched seawater medium (6) minus silica in a regime of 16 hr light and 8 hr darkness. Cultures are presently maintained by Dr. ceratium — ceratium nom masculin Protozoaire très commun dans les mers et les eaux douces, nageur, parfois phosphorescent, et caractérisé par ses expansions pointues.

As dinoflagellates, the organisms have two unlike flagella and have both plant and animal characteristics; their taxonomic placement as algae is contentious. Ceratiumis a genus of the phlyum Dinoflagellata. They are easily distingued from other types of dinoflagellates because of their morphological characteristics, described below. They are a relatively harmless group of organisms that play an important role as both predaotrs and prey in their environment. Ceratium Schrank (Figs. 3G and 8A–D) Thecal tabulation 4′, 5″, 5′″, 2″″; only genus with 1–2 horns formed from postcingular plates, with an apical horn (apical plates) which may have an apical pore and antapical horn (anatapical plates), heavily thecate, plates ornamented, mixotrophic, pale yellow to golden, no eyespot.
