Ceratium is a ubiquitous thecate dinoflagellate genus, slow growing, characteristically found during all seasons and contributing substantially to annual primary production in the world's oceans (Dodge and Marshall, 1994).
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
Describe the arrangement of the flagella in Ceratium. pellicle. The dinoflagellate nucleus is unusual. The nucleus of the Dinoflagellata has many odd features unique to the group. The DNA does have repeated sequences like other eukaryotes, but does not seem to have histones (basic proteins which the DNA coils around) -- though reports vary as to whether or not basic proteins exist in the group.

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. (Baek et al., 2008a, b, c).
Ceratium is a large freshwater mixotrophic dinoflagellate protected by rigid cellulose armor, characteristic summer inhabitant of temperate stratified lakes with low surface nutrient concentrations.
These organisms are unique because they can undergo a special chemical reaction at night that helps defend them against predators. Ceratium is a genus of the phylum dinoflagellata. They are easily distinguished from other types of dinoflagellates because of their morphological characteristics, described below.
The cell is characteristic in form, having a single anterior and two or three posterior horns, and is compressed dorso-ventrally. An apical pore opens at the end of the straight anterior horn. The wall consists of four precingular and four apical plates in the epicone and of five postcingular and two antapical plates in the hypocone.

Ceratium semipulchellum (J0rgensen) Steemann Nielsen (Fig. 14) As with many other species of Ceratium, there is considerable difference of opinion as to whether C. semipulchellum is a complete, separate species or a variant of the closely similar Ceratium pulchellum or Ceratium … The dinoflagellate Ceratium does not have the characteristic shape of other dinoflagellates.
