| dinoflagellate | Photosynthetic organisms of the order Dinoflagellida (for botanists Dinophyceae). They are aquatic and have 2 flagella lying in grooves in an often elaborately sculptured shell or pellicle that is formed from plates of cellulose deposited in membrane vesicles. The pellicle gives some dinoflagellates very bizarre shapes. Their chromosomes lack centromeres and may have little or no protein and may perhaps be intermediate between pro and eu karyote types, hence the group has been termed mesokaryotic. The nuclear membrane persists during mitosis. They are very abundant in marine plankton. Gymnodinium and Gonyaulax, that causes red tide, produce toxins that if accumulated by filter feeding molluscs can be fatal. Another common genus is Peridinium. (18 Nov 1997) |

The dinoflagellates are a large group of flagellate protists. Most are marine plankton, but they are common in fresh water habitats as well. About half of all dinoflagellates are photosynthetic, and these make up the largest group of algae aside from the diatoms. Some species, called zooxanthellae, are endosymbionts of marine animals and protozoa, and play an important part in the biology of coral reefs. ...

| dinoflagellate |
Single-celled algae, mainly marine and often with a cellulose shell; some species may be luminescent, and some cause the red tides that are extremely toxic to marine life.

| dinoflagellate |
a single-celled organism found in fresh and marine waters with characteristics of both plants (eg, photosynthesis) and animals (eg, uses outside organic sources of nutrition). Many harmful algae blooms are caused by dinoflagellates.
