The Subphylum Dinozoa is a member of the Phylum Myzozoa. Here is the complete "parentage" of Dinozoa:

The Subphylum Dinozoa is further organized into finer groupings including:

The dinoflagellates (Greek d???? dinos "whirling" and Latin flagellum "whip, scourge") are a large group of flagellate protists. Most are marine plankton, but they are common in fresh water habitats as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey . Dinoflagellates are the largest group of marine eukaryotes aside from the diatoms. Being primary producers makes them an important part of the aquatic food chain. Some species, called zooxanthellae, are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are colorless predators on other protozoa, and a few forms are parasitic (see for example Oodinium, Pfiesteria). [more]






The Syndiniales are an order of dinoflagellates, found exclusively as endosymbionts of the tintinnid ciliates, crustacea and fish, protozoa, algae, other dinoflagellates. The trophic form is often multinucleate, and ultimately divides to form motile spores, which have two flagella in typical dinoflagellate arrangement. They lack a theca and chloroplasts, and unlike all other orders, the nucleus is never a dinokaryon. A well-studied example is , which is a parasite of other dinoflagellates and may play a part in ending red tides. [more]

At least 23 species and subspecies belong to the Class Syndiniophyceae.
