4. Dinoflagellates are known as the source of red tides and one of the sources of oceanic bioluminescence. "Red tides," also known as harmful algal blooms, occur when phytoplankton (photosynthesizing protists) release harmful chemicals into the water to kill fish and other organisms that threaten to eat them. Symbioses are widespread in nature and occur along a continuum from parasitism to mutualism.

Dinoflagellates examples

For example, the abundance ratio between two major dinoflagellates groups, the Gonyaulacaceae and Peridiniaceae, is routinely used as an indication for productivity and/or nutrient availability in surface waters (Dale, 1996; Sluijs et al., 2005). Dinoflagellates: A Brief Overview. Though most dinoflagellates are marine planktons, some of them are also found in freshwater ecosystems. They are known to possess the characteristics of both flora and fauna and serve as a crucial link in the food chain.

Mostly photosynthetic, dinoflagellates provide the basis of aquatic primary production; most taxa are free-living, while some can form symbiotic and parasitic associations with other organisms.

[2] Dinoflagellates use flagella to move through the water. Although land plants are restricted by their roots, I find it interesting that plants have not evolved systems for movement at least in the Examples of dinoflagellates causing marine die-offs are Ptychodiscus brevis (= Gymnodinium breve) which causes fish deaths when the numbers of organisms reach about 1−2.5 × 10 5 and Ceratium fusus which has caused die-offs of oyster larva (Cardwell, 1978; Cho, 1981). When the dinoflagellates are ingested by shellfish, for example, the chemicals accumulate in the shellfish tissue in high enough levels to cause serious neurological affects in birds, animals, or people which ingest the shellfish. There are several types of neurotoxins produced by dinoflagellates. Early botanists classified dinoflagellates as a separate division of algae, which they named Pyrrophyta, after the Greek word ‘pyrr(h)os’ meaning fire.
