The term derives from the Greek word δῖνος (dînos), meaning whirling, and Latin flagellum, a diminutive term for a whip or scourge. In the 1830s, the German microscopist Christian Gottfried Ehrenberg examined many water and plankton samples and proposed several dinoflagellate genera that are still used today including Peridinium ...
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
Organisms producing calcareous structures are exclusively found in a small group of peridinoid dinoflagellates, called calcareous dinoflagellates.Such calcareous structures are either dinocysts (systematized as Calciodinelloideae [1]), which are formed during the life cycle (i.e., mostly hypnozygotes, after sexual reproduction, or resting stages; an overview of potential cyst formations is ...
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.
Dinotoxins are a group of toxins which are produced by flagellate, aquatic, unicellular protists called dinoflagellates.Dinotoxin was coined by Hardy and Wallace [1] in 2012 as a general term for the variety of toxins produced by dinoflagellates.
Saxitoxin is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp., Gymnodinium sp., Pyrodinium sp.) and freshwater cyanobacteria (Dolichospermum cicinale sp., some Aphanizomenon spp., Cylindrospermopsis sp., Lyngbya sp., Planktothrix sp.) [1] [2] Saxitoxin accumulates in "planktivorous invertebrates, including mollusks (bivalves and gastropods ...
A light micrograph of an ocelloid-containing dinoflagellate. The nucleus is marked n, the ocelloid is indicated with a double arrowhead, and a posterior cell extension is indicated with an arrow; scale bar = 10 μm.
Dinokaryota is a main grouping of dinoflagellates.They include all species where the nucleus remains a dinokaryon throughout the entire cell cycle, which is typically dominated by the haploid stage.
