Several dinoflagellates, both thecate (e.g. Ceratium hirundinella, [60] Peridinium globulus [58]) and nonthecate (e.g. Oxyrrhis marina, [56] Gymnodinium sp. [62] and Kofoidinium spp. [63]), draw prey to the sulcal region of the cell (either via water currents set up by the flagella or via pseudopodial extensions) and ingest the prey through the ...
His greatest work was the development of the universal "Kofoid System" that classified dinoflagellates based on plate morphology very detailed drawings and well-defined structures. Unfortunately, however Kofoid divided Gonyaulax into 4 subgenera based on shape, and included several species that should not have been classified under the name ...
Peridinium is a genus of motile, marine and freshwater dinoflagellates. [1] [2] Their morphology is considered typical of the armoured dinoflagellates, and their form is commonly used in diagrams of a dinoflagellate's structure. [1] [3] Peridinium can range from 30 to 70 μm in diameter, and has very thick thecal plates. [1] [3]
Ceratium species belong to the group of dinoflagellates known as dinophysiales, meaning they contain armored plates. [2] They contain a pellicle, which is a shell, that is made from the cell membrane and vesicles; vesicles are composed of cross-linked cellulose , forming the plates. [ 2 ]
Amphidinium is a genus of dinoflagellates. The type for the genus is Amphidinium operculatum Claparède & Lachmann. The genus includes the species Amphidinium carterae which is used as a model organism. [1] As dinoflagellates, Amphidinium spp. have chloroplasts. The Amphidinium chloroplast genome is unusual in not having a single contiguous ...
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. All the "typical" dinoflagellates, such as Peridinium and Gymnodinium, belong here.
Zooxanthellae (/ ˌ z oʊ ə z æ n ˈ θ ɛ l iː /; sg. zooxanthella) is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs.
Symbiodinium is a genus of dinoflagellates that encompasses the largest and most prevalent group of endosymbiotic dinoflagellates known and have photosymbiotic relationships with many species. These unicellular microalgae commonly reside in the endoderm of tropical cnidarians such as corals , sea anemones , and jellyfish , where the products of ...
