The name scintillon was first used to describe cytoplasmic particles isolated from a bioluminescent species of dinoflagellate that were able to produce a flash of light in response to a decrease in pH. [4] Scintillons were first observed in L. polyedra by fluorescence microscopy, [5] where
Dinoflagellate blooms are generally unpredictable, short, with low species diversity, and with little species succession. [73] The low species diversity can be due to multiple factors. One way a lack of diversity may occur in a bloom is through a reduction in predation and a decreased competition.
It is a marine dinoflagellate commonly found in the waters of the Gulf of Mexico. [1] It is the organism responsible for the "Florida red tides" that affect the Gulf coasts of Florida and Texas in the U.S., and nearby coasts of Mexico. K. brevis has been known to travel great lengths around the Florida peninsula and as far north as the ...
Dinoflagellate luciferin is a chlorophyll derivative (i. e. a tetrapyrrole) and is found in some dinoflagellates, which are often responsible for the phenomenon of nighttime glowing waves (historically this was called phosphorescence, but is a misleading term).
Biofluorescence is fluorescence emitted by a living organism. Biofluorescence requires an external light source and a biomolecular substance that converts absorbed light into a new one. The fluorescent substance absorbs light at one wavelength, often blue or UV, and emits at another, longer wavelength, green, red, or anything in between.
Pyrocystis fusiformis is a non-motile, tropical, epipelagic, marine dinoflagellate (flagellate microorganisms), reaching lengths of up to 1 millimetre (0.039 in). P. fusiformis display bioluminescence when disturbed or agitated. In coastal marine waters, this dinoflagellate causes glowing effects after dark.
Gambierdiscus toxicus is a species of photosynthetic unicellular eukaryote belonging to the Alveolata, part of the SAR supergroup.It is a dinoflagellate which can cause the foodborne illness ciguatera, [1] and is known to produce several natural polyethers including ciguatoxin, maitotoxin, gambieric acid, and gambierol.
The most common species is Noctiluca scintillans, also called N. miliaris.Blooms of this species are red-orange and can be bioluminescent when disturbed, [4] as are various other dinoflagellates, and large blooms can sometimes be seen as flickering lights on the ocean, known as the milky seas effect.
