They were first described in 1885 by the German naturalist Johann Adam Otto Buetschli. They are a fairly large group, including photosynthetic, heterotrophic, free-living organisms, parasites, and symbionts.

2010-08-07 · There are roughly 2,000 known species of Dinoflagellata. They are unique organisms because although they are usually treated as plants, dinoflagellates assume some animal characteristics, such as preying on smaller organisms for food. Genome Structure. There is not yet an extensive body of research on most dinoflagellate species.
