17 May 2018 For example, in 2008, an intense bloom in the St Lawrence Estuary was found to be responsible for the death of many fish, bird and mammal.

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. Dinoflagellates are eukaryotic cells with whirling flagella. It’s the middle of the night. Angry waves of high tide are smacking against the sandy shore and frisking about slippery rocks, when Dinoflagellates multiply rapidly and often lead to population explosions. A toxin is released by the blooms, which is considered to be extremely poisonous.

Dinoflagellates are microorganisms that are regarded as algae. Their wide array of exotic shapes and, sometimes, armored appearance is distinct from other algae. The closest microorganism in appearance are the diatoms. Dinoflagellates are single-celled organisms. There are nearly 2000 known living species.

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.

Other organisms use bioluminescence to attract mates, to lure potential prey, or as a means of communication. They are found in both marine and freshwater

Introduction. Marine dinoflagellates are the main contributors to a phenomenon commonly known as phosphorescence of the sea. When the concentration of these bioluminescent organisms in the water near shore is high, the wave crests glow with a luminous blue light (see Figure 1, below). Wet sand on the beach even glows blue when you step on it!
