Gonyaulax Taxonomy

There are over 2000 species of living dinoflagellates. Half of these are photosynthetic, while half are heterotrophic. All species of Gonyaulax are photosynthesizers. Dinoflagellates are grouped into two major groups, based upon the presence or absence of a theca. Those without a theca are called Syndinea, and are often termed zooxanthellae and are symbiotic with coral. Dinoflagellates that possess a theca are called Dinokaryota. They are free-living and are further classified by their thecal plate and flagellar structure.
