Perkinsid
Perkinsidae is a family of Alveolata, alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates. Members It includes ''Perkinsus'' species, which are parasitism, parasitic protozoans, some of which cause disease and mass mortality in wild and farmed mollusca, molluscs such as oysters. There are two genus, genera: *''Parvilucifera'', a genus of 3 species *''Perkinsus'', a genus of 7 to 8 species Characteristics Perkinsidae possess plastids which do not contain DNA.

Dinoflagellate
The dinoflagellates (Greek δῖνος ''dinos'' "whirling" and Latin ''flagellum'' "whip, scourge") are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata and are usually considered algae. Dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats. Their populations vary with sea surface temperature, salinity, and depth. Many dinoflagellates are photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy and myzocytosis). In terms of number of species, dinoflagellates are one of the largest groups of marine eukaryotes, although substantially smaller than diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (for example, ''Oodinium'' and ''Pfiesteria''). Some dinoflagellates pro ...
