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 known marine species. [9] [10] Dinoflagellates are alveolates possessing two flagella, the ancestral condition of bikonts.
Karenia follow the typical life cycle of a dinoflagellate with a motile, haploid, asexual cell with regular mitotic divisions. [1] This binary fission reproduction occurs once about every 2–10 days, and division occurs primarily at night (Brand et al., 2012). [ 1 ]
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. [8]
This category contains valid dinoflagellate species names. Alternate names (i.e. junior synonyms) are not included here. Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus article.
Alexandrium is an opportunistic dinoflagellate and thus it can bloom in nutrient-rich and nutrient-poor areas. For most species, in order for the bloom to be positively regulated it must be in a water body with high surface water temperatures, maximum water column stability, low nutrients, and low winds.
