The term derives from the Greek word δῖνος (dînos), meaning whirling, and Latin flagellum, a diminutive term for a whip or scourge. In the 1830s, the German microscopist Christian Gottfried Ehrenberg examined many water and plankton samples and proposed several dinoflagellate genera that are still used today including Peridinium ...
Ceratium species belong to the group of dinoflagellates known as dinophysiales, meaning they contain armored plates. [2] They contain a pellicle, which is a shell, that is made from the cell membrane and vesicles; vesicles are composed of cross-linked cellulose , forming the plates. [ 2 ]
The term presently does not imply any specific relationship or classification of the organisms that possess flagella. However, several derivations of the term "flagellate" (such as "dinoflagellate" and "choanoflagellata") are more formally characterized. [1]
Gambierdiscus toxicus is a species of photosynthetic unicellular eukaryote belonging to the Alveolata, part of the SAR supergroup.It is a dinoflagellate which can cause the foodborne illness ciguatera, [1] and is known to produce several natural polyethers including ciguatoxin, maitotoxin, gambieric acid, and gambierol.
Amphidinium is a genus of dinoflagellates.The type for the genus is Amphidinium operculatum Claparède & Lachmann. The genus includes the species Amphidinium carterae which is used as a model organism.
Dinokaryota is a main grouping of dinoflagellates.They include all species where the nucleus remains a dinokaryon throughout the entire cell cycle, which is typically dominated by the haploid stage.
Some dinoflagellates that live as parasites are probably mixotrophic. [7] Karenia, Karlodinium, and Lepidodinium are some of the dinoflagellate genera which are thought to contain peridinin, a carotenoid pigment necessary for photosynthesis in dinoflagellates; [8] however, chlorophyll b has been found in these genera as an accessory pigment.

Pyrocystis fusiformis is a non-motile, tropical, epipelagic, marine dinoflagellate (flagellate microorganisms), reaching lengths of up to 1 millimetre (0.039 in). P. fusiformis display bioluminescence when disturbed or agitated. In coastal marine waters, this dinoflagellate causes glowing effects after dark.
