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. Ceratiumspecies 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 monocerashas a single, apical horn.

3G and 8A–D) Thecal tabulation 4′, 5″, 5′″, 2″″; only genus with 1–2 horns formed from postcingular plates, with an apical horn (apical plates) which may have an apical pore and antapical horn (anatapical plates), heavily thecate, plates ornamented, mixotrophic, pale yellow to golden, no eyespot. The genus Ceratium includes species of freshwater and marine dinoflagellates. Most species of Ceratium are unicellular organisms that are characterized by their armored plates, two flagella, and horns. Species of Ceratium are found worldwide and are of concern due to their blooms. Ceratium [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.

(1988) and Regenfors (1994) C. hirundinella and C. furcoides can be morphologically set apart, but their ecological requisites are very similar, so they are frequently considered as Ceratium spp. IN describing the specific characteristics of Ceratium furca, one of the Peridiniæ or Dinoflagellates, Saville Kent in his ``Manual of the Infusoria'' gives the habitat as salt-water, and he appends a note to the effect that, ``although usually regarded as entirely marine, M. Werneck has reported the occurrence of an apparently identical species in fresh-water in the vicinity of Salzburg.'' These characteristics may contribute to explain why many dinoflagellates are able to grow even when nutrient concentrations reach their seasonal minima.

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 However, there is a paucity of data on ecological parameters of C. furca blooms in Asian coastal areas, although ecological and physiological characteristics of Ceratium species have been examined by Baek et al.

According to Heaney et al. (1988) and Regenfors (1994) C. hirundinella and C. furcoides can be morphologically set apart, but their ecological requisites are very similar, so they are frequently considered as Ceratium spp. IN describing the specific characteristics of Ceratium furca, one of the Peridiniæ or Dinoflagellates, Saville Kent in his ``Manual of the Infusoria'' gives the habitat as salt-water, and he appends a note to the effect that, ``although usually regarded as entirely marine, M. Werneck has reported the occurrence of an apparently identical species in fresh-water in the vicinity of Salzburg.'' These characteristics may contribute to explain why many dinoflagellates are able to grow even when nutrient concentrations reach their seasonal minima. 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.
