Grazing by microzooplankton such as rotifers, red tide formation and persistence suggest that graz ing pressure may sometimes play an important role in red tide dynamics (e.g. Watras et al. 1985). Some cope pods and fish larvae are known to feed on some local red tide dinoflagellates (Lasker et al. 1970, Paffenhöfer 1976).

Red tide dinoflagellates： Left: Gymnodinium mikimotoi right: Prorocentrum micans. Some representative dinoflagellates causing red tide blooms Gymnodinium catenatum Alexandrium tamarense （PSP） Dinophysis fortii （DSP） Gymnodinium mikimotoi Gambierdiscus toxicus （Ciguatera) A rapid accumulation of certain dinoflagellates can result in a visible coloration of the water, colloquially known as red tide (a harmful algal bloom), which can cause shellfish poisoning if humans eat contaminated shellfish. Some dinoflagellates also exhibit bioluminescence—primarily emitting blue-green light 2019-07-05 · At least three species of dinoflagellates and one diatom species are responsible for the toxic mess of red tides in the United States. These microscopic forms of algae produce toxins that can Protoperidinium bipes is a single-celled organism belonging to a group of algae called dinoflagellates. This globular, polygonal-shaped dinoflagellate is armored, meaning it has a hard outer coating. The outer surface of the cell has a detailed ornamental pattern, with a “horn,” or thick spine, at the top and two at the base.

During the daytime, due to the pigmentation of the dinoflagellates, the water can turn a deep red, brown, or orange color, giving red tides their name. A bioluminescent dinoflagellate can make a flash of light inside its cell when disturbed.

The phenomenon is associated with a red tide, or an algae bloom, filled with dinoflagellates which react with bioluminescence when jostled by the moving water. During the daytime, due to the Most dinoflagellates are protected with red-brown, cellulose armour. Like other phytoplankton, dinoflagellates are r-strategists which under right conditions can bloom and create red tides. Excavates may be the most basal flagellate lineage. By trophic orientation dinoflagellates cannot be uniformly categorized.
