Description Phaeocystis pouchetii forms spherical or more irregular colonies, which according to Baumann et al. (1994) measure 1.5 - 2 mm in size. The colonies form clouds, in which the cells are placed in groups separated by cell-free mucilage. The life history of this species presents at least two different stages. The colony-forming stage is the most conspicuous, and the yellow-green colonies may attain a size of several millimetres. The cells are embedded in mucilage, forming a monolayer at the periphery of the colony. The shape of the colony varies from spherical to irregular motile cells. Individual cells are 4–8 μm long and usually contain an average of two (1–4) chloroplasts. They lack flagella and a haptonema. Scales are also absent. The motile stage is unicellular, 3–8 μm long, biflagellate, with a very short haptonema which is difficult to see in the light microscope. The cells usually contain two chloroplasts. The surface is covered with submicroscopic flat scales of two kinds. Cells of some clones contain trichocyst-like structures which appear as pentagonal stars after discharge from the cell. Other clones lack this material. Several types of motile cells have been described and at least some of these are capable of self-replication. The colonies probably form from single cells, often seen attached to the setae of the diatom Chaetoceros. The origin of these cells is uncertain, but they appear to represent flagellates, which have settled and resorb the flagella and haptonema. The single cells divide and eventually form colonies. Free-floating colonies may divide by fragmentation (Moestrup and Larsen, 1992). [details]

Distribution This species is widely distributed and has been found also in the North Atlantic and Svalbard. Jahnke & Baumann (1987) and Baumann et al. (1994) found the species to grow in a temperature window of -2 -- 12 deg. C, and it appears to be a species of arctic and temperate northern waters. In southern seas and the Antarctic, the morphologically similar P. antarctica occurs.. [details]

Distribution This species is widely distributed and has been found also in the North Atlantic and Svalbard. Jahnke & Baumann (1987) and Baumann et al. (1994) found the species to grow in a temperature window of -2 -- 12 deg. C, and it appears to be a species of arctic and temperate northern waters. In southern seas and the Antarctic, the morphologically similar P. antarctica occurs.. [details]Harmful effect Phaeocystis pouchetii has been found to be toxic to cod larvae in Norway [details]
Identification Phaeocystis pouchetii is a cold-water species which may be identified by the shape of the colonies. Small colonies are spherical while larger colonies are lobed and may reach a size of at least 2 mm. Cells in the colony are often arranged in groups of four in a square. [details]
