Ceratium furca is a primarily photosynthetic dinoflagellate also capable of ingesting other protists. During 1995 and 1996, we documented the abundance of C. furca in Chesapeake Bay and determined grazing rates on prey labeled with fluorescent microspheres. Abundance usually remained below 20 cells ml −1, although the species was capable of localized late-summer blooms (≤ 478 cells ml −1

These 3 forms were later promoted to 2 varieties and 1 Ceratium furca. Physical and biochemical parameters for cells in 'semi-continuous' cultures. Average values were determined for each parameter once steady state had been reached (Days 19 to 30). There is a broad range of cell size: small cells (the aptly named Peridinium inconspicuum) may be 10 μm wide by 12 μm long, and large Ceratium may reach 400 μm in length. This chapter deals with freshwater dinoflagellates, but there is also an extensive literature on marine dino-flagellates.

Ceratium labeled

[…] Ceratium, genus of single-celled aquatic dinoflagellate algae (family Ceratiaceae) common in fresh water and salt water from the Arctic to the tropics. As dinoflagellates , the organisms have two unlike flagella and have both plant and animal characteristics; their taxonomic placement as algae is contentious . Ceratium species belong to the group of dinoflagellates known as dinophysiales, meaning they contain armored plates. 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.

Distribution of scandinavian waters: Maximum length: 0,54 mm. Compare with the size of a hair. Appearance: Living ceratium-dinoflagellates are yellow or brown in colour. They consist of one somewhat flat cell that is not symmetrical. Sometimes the cells are attached to each other in pairs.The surface of the cell is broken by grooves that contain two mobile outgrowths (flagellae).

Protist 161: 35-54. Hansen, G. The flagellar movement produces forward propulsion and also a turning force. The genus of ceratium includes species of freshwater and marine dinoflagellates.

Bij mariene soorten is er anisogamie met een zygotische nucleaire faseverandering. Vegetatief vermenigvuldigen ze zich door een schuine lengtedeling, waarbij de bepantsering schuin op de sulcus wordt opgesplitst en vervolgens wordt aangevuld met de cellen.

We found that K. mikimotoi cultured under conditions of high light intensity could ingest fluorescent microspheres (diameters 0.5 and 2.0 μm) and The genus Ceratium is restricted to a small number of freshwater dinoflagellate species.

In the present study, we modified this method for use in the field to determine food vacuole contents and feeding rates of Ceratium Eurca,

The most notable shared characteristic is the presence of cortical (outer-region) alveoli (sacs). These are flattened vesicles (sacs) packed into a continuous layer just under the membrane and supporting it, typically forming a flexible pellicle (thin skin).
