Neoceratium tripos

Neoceratium tripos is a species of dinoflagellates of the Neoceratium genus.

Anatomy

This chromist is easy to recognize and identify among all the phytoplankton, because of its three horns in a pitchfork arrangement. The horn in the middle is called the apical horn, and it is used as a flagellum. The other two horns are called lateral horns, and they are solely used as an aid for flotation.^[2]

Habitat

This species lives along all the phytoplankton on the ocean surface worldwide, where it is one of the dominant species. Despite this, it is usually solitary, although during reproduction season, several individuals may congregate, all of their apical horns join. This occurs when a cell divides, so that the daughter cells remain together, linked in short chains. This particular species may sometimes be parasitized by other chromists or protists.

History

Neoceratium species were originally classified under the genus Ceratium, however they were reclassified to the new genus Neoceratium in 2009 following a ribosomal RNA sequencing study.^[2]
