| | However, dinoflagellate palynologists have been conspicuously less enthusiastic to grapple with the underlying evolutionary relationships of their subjects than have, say, paleozoologists. | | | At the opposite end of the spectrum are the very large genera, such as Cleistosphaeridium and Cordosphaeridium, which have traditionally found use as catch-alls for sundry cysts from all parts of the stratigraphic column, which almost certainly have little relationship to one another at all. | | | A study of openings and process distribution in Early Paleozoic acritarchs led Lister (1970) to conclude that some may be the cysts of thecate dinoflagellates. |

| | Once she had observed this bizarre and lethal behavior in the laboratory, Burkholder needed proof that this same dinoflagellate was responsible for fish kills in the wild. | | | Plants that can behave like animals, most dinoflagellates resemble the vegetative stage (2), though Lois Pfiester and other researchers have shown that some freshwater dinoflagellates can also experience radical changes of shape. | | | She hypothesizes that changing environmental conditions may have made the world's rivers and bays more conducive to the success of these dinoflagellates than in the past. |

| | Dinoflagellate cysts |
| | Although most, if not all, fossil dinoflagellates are cysts, only a few living genera are known to encyst, either in response to adverse environmental conditions or following sexual reproduction. | | | Our understanding of the diverse morphology, biostatigraphy, environmental and climate relationships of fossil dinoflagellates has advanced considerably during the last four decades. | | | With the amelioration of conditions in spring, the motile stage excysts through the archaeopyle. |

| | The result is that the feeding behavior of the copepod is disrupted and less dinoflagellate prey are consumed. | | | Most dinoflagellates can be cultured in the laboratory. | | | Therfore, light production in dinoflagellates and all other luminescent organisms involves a chemiluminescent reaction in which a substrate, luciferin, is oxidized, releasing a large amount of energy in the form of light. |

| | During the research of this subject, it was found that hard corals were not the only cnidarians discovered as having a symbiotic relationship with dinoflagellates. | | | Dinoflagellates have been known to cause illnesses due to toxins some species manufacture, and they also cause episodes such as red tides. | | | Sea Anemones and jellyfish have been found to have symbiotic associations with dinoflagellates. |

| | Evitt also realised that the spines or processess seen on many cysts reflect the tabulation pattern of the original dinoflagellate from which the cyst emerged. | | | Dinoflagellates possess two flagella, one (the transverse flagellum) may be contained in a groove-like structure around the equator of the organism (the cingulum), providing forward motion and spin to the dinoflagellate, the other (the longitudinal flagellum) trailing behind providing little propulsive force, mainly acting as a rudder. | | | Palaeobiological applications of dinocysts encounter the same problems as biostratigraphic applications. |

| | The zooxanthellae in these corals are dinoflagellates, and it is suspected that there may be a relationship between their diversifications. | | | Because dinoflagellates are sensitive to changes in ocean temperature, salinity, and nutrient levels, the dinoflagellate species that are present in a sediment sample are often used to determine the environmental conditions at the time and place that the sediment was deposited. | | | There is, however, geochemical evidence for the presence of dinoflagellates in the early part of the Paleozoic and late Precambrian, even though no cysts are known. |

| | Symbiotic dinoflagellates are also found in many other cnidarians (including some jellyfish), giant clams, several other types of animals and in some large protists such as foraminifera. | | | Although most dinoflagellates are free-living, it is the symbiotic forms (‘zooxanthellae&;) that are the most famous. | | | Dinoflagellates mostly fall prey to small animals, such as small crustaceans and fish larvae, and to other protists, including, in many cases, other dinoflagellates. |
