The transverse flagellum encircles the short main body which extends into each a long apical and an antapical horn. The plate pattern is identical to that of Ceratium Schrank, therefore it is regarded only as a subgenus or section of Ceratium. Vegetative reproduction by binary fission, sexual reproduction by fusion of anisogametes; planozygotes with 2 longitudinal flagella. Cysts not known. Marine, planktonic, worldwide, mainly in coastal waters, may form mass developments, discolouring the sea water.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
