Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae (e.g. dinoflagellates and diatoms). Certain species of phytoplankton and dinoflagellates like 'Gonyaulax' found in red tides contain photosynthetic pigments that vary in color from brown to red.

På samma sätt, när de växer överdrivet och okontrollerbart, ger de upphov till ett fenomen som kallas "Red Tide", där haven är färgade med olika färger.

However, it is a different species of dinoflagellate. The Florida red tide that occurs in the Gulf of Mexico is from an algae called Karenia brevis. This red tide has also occurred regularly on the Gulf Coasts for many years. However, as pollution grows in the area, the red tide bloom in that area has had an unprecedented overgrowth.

Dinoflagellates red tide

When the dinoflagellates in red tides die, they are consumed by other microbial species. When these microbes reproduce and multiply, they consume oxygen in the water, just like marine animals. Dinoflagellate definition is - any of an order (Dinoflagellata) of chiefly marine planktonic usually solitary unicellular phytoflagellates that include luminescent forms, forms important in marine food chains, and forms causing red tide.

Up to 50 million cells per litre (quart) of the species Gymnodinium brevis caused a red tide off the Florida coast in 1947 and turned the water from green to yellow to amber; thousands of fishes died. Red tides are caused by the rapid multiplication of dinoflagellates, a type of phytoplankton. There is no single cause of red tides or other harmful algae blooms, though abundant nourishment must Florida red tide is a specific type of Harmful Algae Bloom (HAB) It is caused by a dinoflagellate or microscopic algae, Karenia brevis (K. brevis) It is called a dinoflagellate because it has two flagella or tail like appendages that propel it thorough the water Dinoflagellates are perhaps best known to the public as the source of red tides leading to fish and other marine animal kills, as well as various types of human illness caused by their toxins: paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning, diarrhetic shellfish poisoning, and ciguatera (Landsberg, 2002; Hallegraeff et al., 2003). The University of the Philippines at Los Baños (UPLB) said the name red tide was coined due to the sea water discoloration which ranges from amber, red, brown, yellow orange to purple caused by the highly-densed population of dinoflagellates.

some red-tide dinoflagellates, including H. triquetra, are able to ingest Synechococcus. Therefore, the following basic questions arise: (1) Are most red-tide dino-

It is a common name for harmful algal blooms occurring along coastal regions, which are resulted from large concentrations of aquatic microorganisms, such as protozoans and unicellular algae (e.g. dinoflagellates and diatoms). 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. This light is the result of a chemical reaction using a light emitting molecule called luciferin. K. brevis, the dinoflagellate causing red tides in Florida, can cause respiratory problems, particularly for people with asthma or allergies.
