Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (for example, Oodinium and Pfiesteria). Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts , as part of their lifecycles; this occurs in 84 of the 350 described freshwater species and a little more than 10% of the ...
For example, mixotrophic and heterotrophic dinoflagellates may act as predators on a wide range of prey types due to their diverse feeding mechanisms. [12] Including mixotrophic dinoflagellates would better explain the control of prey population and cycling of limited materials as well as competition between other organisms for larger prey. [12]
Some dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy). [76] Some species are endosymbionts of marine animals and other protists, and play an important part in the biology of coral reefs .
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 ]
Dinoflagellates(Dinoflagellata) are a phylum of Alveolates eukaryotes. The taxon is subdivided in 8 classes (Ellobiophyceae, Psammosea, Oxyrrhea, Pronoctilucea, Duboscquellea, Syndiniophyceae, Noctiluciphyceae and Dinophyceae).
Some dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy).

Dinophysis is a genus of dinoflagellates [1] [2] [3] common in tropical, temperate, coastal and oceanic waters. [4] It was first described in 1839 by Christian Gottfried Ehrenberg. [5] Dinophysis are typically medium-sized cells (30-120 μm). [5] The structural plan and plate tabulation are conserved within the genus. [4]
Symbiodinium is a genus of dinoflagellates that encompasses the largest and most prevalent group of endosymbiotic dinoflagellates known and have photosymbiotic relationships with many species. These unicellular microalgae commonly reside in the endoderm of tropical cnidarians such as corals , sea anemones , and jellyfish , where the products of ...
