Generna i den Ceratium furca , en peridinininnehållande dinofyt. Den vanligaste The phylum Dinophyta (dinoflagellates, dinophytes) is composed of a diverse assemblage of unicellular organisms. Most of them are biflagellated and free-swimming (e.g., among the Peridiniales, Ceratium, Peridinium, Gymnodinium) (Figure 1), whereas a few are nonmotile unicells reproducing by motile specialized cells (zoospores and gametes) with features such that to permit their inclusion among Ceratium species are easily identifiable because of their unique shape. They are covered with an armor-like cell wall, made out of polysaccharidel. The most distinguishing characteristic are the arms (also known as horns), the shape and size of which vary from species to species.

[…] 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.

Some dinoflagellates possess the remarkable genetic, biochemical, and cellular machinery to produce bioluminescence. Bioluminescent species appear to be ubiquitous in surface waters globally and include numerous cosmopolitan and harmful taxa. Nevertheless, bioluminescence remains an enigmatic topic in biology, particularly with regard to the organisms’ lifestyle. In this paper, we review the

dinoflagellates A division (Dinoflagellata) of protists that are heterotrophs but closely allied to brown algae and diatoms (they are sometimes classified as algae). Many have brown or yellow chromoplasts containing xanthophyll and chlorophylls a and c; others are colourless. 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.

In Sagami Bay, C. fusus increased significantly from April to September, and decreased from November to February, though it was found at all times through PHYLUM DINOFLAGELLATES – Ceratium characteristics: single-celled plankton that are important primary producers in freshwater and marine environments. Most possess chloroplasts containing chlorophyll and a yellow-brown accessory pigment, but some are heterotrophic. Dinoflagellates have a cellulose cell wall that consists of overlapping armored 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.

Introduction to the Dinoflagellata. Dinoflagellates are unicellular protists which exhibit a great diversity of form. The largest, Noctiluca, may be as large as 2 mm in diameter!Though not large by human standards, these creatures often have a big impact on the environment around them.

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.
