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.

Title Ceratium balechii sp. nov. (Dinophyceae: Gonyaulacales) del Pacífico Mexicano I. Salgado-Ugarte INTRODUCTIONThe genus Ceratium Schrank is one of the most important marine phytoplankton components, including around 80 "species" not considering other 30 dubious species (Sournia, 1986). 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.

Ceratium sp. are generally considered harmless and produce non-toxic chemicals. Under certain conditions that promote rapid growth of the population, Ceratium sp. blooms known as Red Tides can deplete the resources and nutrients of the surrounding environment.
