During cytokinesis, the cleavage furrow is surrounded by a system of membranes which, together with the thecal plates, will comprise the future cell covering. The book begins with a general introduction and a taxonomic description of the dinoflagellates both to acquaint those unfamiliar with this group of organisms and to set the tone for the rest of the volume. The dinoflagellate Ceratium is a ubiquitous thecate dinoflagellate genus, slow growing, characteristically found during all seasons, and contributing substantially to the take annual primary production in the world ocean (Graham, 1941, Nordli, 1957, Elbrächter, 1973, Weiler, 1980, Matrai, 1986, Dodge and Marshall, 1994). This will be important as both Ceratium and Protoperidinium are highly represented in natural bioluminescent dinoflagellate populations . This species is distinguished from C. brachyceros by the presence of "shoulders" in C. hirundinella, the apical horn is distinct from the body.
