Ceratium species are covered by a theca, or armour, composed of many textured plates that form one horn in the front and usually two in the back; these horns slow the sinking of the organism. The body form varies according to the salt content and temperature of the surrounding water: the spines tend to be short and thick in cold, salty water and long and thin in less salty, warmer water.

Changes in the annual population densities of Ceratium spp. in three adjacent English lakes, Windermere, Esthwaite Water and Blelham Tarn, are summarised over the 41 year period 1945–1985. In these lakes the genus is represented by two species, C. hirundinella (O.F. Müll) Bergh. and C. furcoides (Levander) Langhans. Although the species have not been distinguished over the entire study Ceratium sp.

Ceratium migrated into these interflows at night, with corresponding increases and decreases in surplus cellular P and alkaline phosphatase activity, respectively. Giga-fren These results directly support the hypothesis that Ceratium can access multiple P sources through vertical migration.
