Ceratium species are characterized by their horns and two flagella located in the transverse and longitudinal positions. Ceratium species belong to the group of dinoflagellates known as Gonyaulacales, meaning they contain armored plates. [2] .

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 …

Sep 29, 2024 · 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.

Ceratium along with Peridinium is a common bloom forming dinoflagellate in freshwater lakes, and proliferate in relatively nutrient-poor but organically rich habitats. Although marine species of Ceratium are often associated with ‘red tides’ there does not appear to be evidence that they produce secondary metabolites toxic to fish or mammals.

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.

In this article we will discuss about the structure of ceratium. This will also help you to draw the structure and diagram of ceratium. (1) It is a fresh water as well as a marine form and is free living.

The largest dinoflagellate blooms in both lakes and the ocean are formed by species of the large, armored genus Ceratium during the autumn. For unknown reasons, grazing pressure on this genus is low, suggesting that survival rather than fast growth rates is the major reason for bloom build up over the late summer.

Ceratium is a unicellular organism and a member of the family Ceratiaceae, commonly known as dinoflagellates. Dinoflagellates are usually considered algae but mostly are marine planktons. Ceratium genus comprises a rather small number of about 7 freshwater dinoflagellate species.

Ceratium-dinoflagellates can, mainly during the autumn, be so many that the water is coloured red. They can also emit light that is visible in the dark and appear as seasparkle. Classification: Ceratium-dinoflagellates are members of the dinoflagellate group under the "protists".

Ceratium fusus is a solitary cell that contains numerous yellow-brown chloroplasts (EOL 2012). It has both sexual and asexual cycles of reproduction and is mixotrophic (Scott and Brandt 2011).
