Species

The genus Ceratium includes species of freshwater and marine dinoflagellates.[1] Most species of Ceratium are unicellular organisms[1] that are characterized by their armored plates, two flagella, and horns.[2] Species of Ceratium are found worldwide and are of concern due to their blooms.

Taxonomy

The genus was originally published in 1793 by Shrank, F. von Paula.[3] The taxonomy of Ceratium varies among several sources. One source states the taxonomy as: Kingdom Chromista, Phylum Miozoa, Class Dinophyceae, Order Gonyaulacales, and Family Ceratiaceae.[3] Another source lists the taxonomy as Kingdom Protozoa, Phylum Dinoflagellata, Class Dinophyceae, Order Gonyaulacales, and Family Ceratiaceae.[4] The taxonomic information listed on the right includes Kingdom Chromalveolate. Thus, sources disagree on the higher levels of classification, but agree on lower levels.
