More specifically, the largest slow growing species (e.g., Ceratium, Peridinium) are able to develop substantial biomass because loss rates (either due to grazing or sinking) also are moderate. Marine dinoflagellates are able to form localized ‘red tides’, which can sometimes cause, with the production of specific toxins, various human illnesses. ABSTRACT: Feeding in the mixotrophc dinoflagellate Ceratium furca was investigated using 1 pm fluorescent microspheres to label prey. Microspheres added to natural plankton assemblages at a con- centration of 5 X 106 to 107 rnl-' were rapidly ingested by a variety of planktonic organisms including 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 … Ceratium Ceratium Schrank [ref. ID; 1618] Body flattened; with one anterior and one to four posterior horn-like processes; often large; chromatophores yellow, brown, or greenish; color variation conspicuous; fission is said to take place at night and in the early morning; fresh or salt water.

AphiaID. 156511 (urn:lsid:marinespecies.org:taxname:156511) ABSTRACT: Feeding in the mixotrophic dinoflagellate Ceratium furca was investigated using 1 μm fluorescent microspheres to label prey. Microspheres added to natural plankton assemblages at a concentration of 5 x 10 6 to 10 7 ml-1 were rapidly ingested by a variety of planktonic organisms including small flagellates, ciliates, dinoflagellates, ebriids and amoebae. Ceratium fusus forms extensive blooms forming red tides in Eastern Asia regions (China, Philippines and Thailand; Baek et al. 2007). Habitat Ceratium fusus is mainly a coastal species, but it can be found in estuarine and oceanic environments (Montagnes 2006, Horner 2002).

In addition, some species have Ceratium fusus, in Coastal Area of Sagami Bay, Japan. SEUNG HO BAEK*, SHINJI Ingestion of fluorescently-labeled and phycoerythirin-con- taining prey by Incubation experiments can last for 6 h, allowing sufficient time for the appearance of labeled food vacuoles in predators with low feeding rates.

labeled prey with presumably unaltered surface char- acteristics. Prey ciliates so labeled were ingested by larger ciliates and could be detected using fluores- cence microscopy. In the present study, we modified this method for use in the field to determine food vacuole contents and feeding rates of Ceratium Eurca, Micrographs showing ELF labeled bacteria: (A) on the surface of an Oxyphysis cell, (B) on the surface of a Prorocentrum micans cell; (C) on the surface of an unidentified dinoflagellate cell (D) associated with lysed Ceratium furca cell debris, (E) associated with particulate material, (F) associated with particulate material and aggregated cells of P. micans. The seasonal abundance of the dominant dinoflagellate, Ceratium fusus, was investigated from January 2000 to December 2003 in a coastal region of Sagami Bay, Japan. The growth of this species was also examined under laboratory conditions.

The pellicle divides into two structures known as the epicone and hypocone that lie above and below the transverse Armored dinoflagellates have two major plate regions composed of two to 100 individual plates. The edges of the plates overlap, sliding apart as the cell increases in size and allowing the cell to expand.
