It is a member of the family Ceratiaceae and Class Dinophyceae and morphologically close to the species Ceratium hirundinella (D.F. Müller) Dujardin 1841 in many characteristics. The main difference between the two species is related to the number of the apical plates.

Ceratium is a large freshwater mixotrophic dinoﬂagellate protected by rigid cellulose armor, characteristic summer inhabitant of temperate stratified lakes with low surface nutrient concentrations.

Leaves are evergreen. Ceratium is a genus of the phylum dinoflagellata. They are easily distinguished from other types of dinoflagellates because of their morphological characteristics, described below. They are a relatively harmless group of organisms that play an important role as both predators and prey in their environment.

Ceratium characteristics

Characteristics. With an area of 6.7 hectares and average depth of 1.5 metres maximum 2.5 metres, Kyrkosjon contains 80.000 cubic metres of water and is Ceratium dinoflagellates are characterized by their armored plates, two flagella, and horns. They are found worldwide and are of concern due to their blooms. 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.

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.

ABSTRACT Limnological and morphological characteristics of Ceratium furcoides blooms (Dinophyta) in a shallow lake in central Chile Dinoﬂagellates of the Ceratium genus form non-toxic blooms in freshwater ecosystems, generating diverse ecosystem, Algae are the green slimy blanket which covers the rock surface or the top of the ponds or a poorly kept aquarium that have the ability to conduct photosynthesis. The algae belong to the subphylum Thallophyta of the kingdom Protista in modern classification of organisms. Latin ‘alga’ means seaweed.

eter (Dolan et al., 2002). As the smallest Ceratium species is about 100microns, and most tintinnids have an oral di-ameter of 30–40microns, it is unlikely that tintinnids feed on Ceratium. Furthermore, there are no reports of tintinnids consumming Ceratium. Here we compare the community characteristics of these
