Brief Summary

由Ecomare提供
You may have never heard of Phaeocystis, but if you ever take a walk along the beach in late spring or summer and see lots of foam along the waterline, you are looking at these one-celled algae. No wonder it's nicknamed foam algae. Phaeocystis is brown and slimy. Lots of people mistake the brownish foam as pollution. However, it is a natural phenomenon. After the algae have died (blossomed), the wind and waves whip it up into foam. The foam is eventually degraded by bacteria.

由Harmful Phytoplankton Project提供
Phaeocystis globosa occurs in two stages: flagellated cells and nonmotile cells forming colonies. The nonmotile stage forms smooth round colonies, not forming lobes, with cells distributed evenly along the surface of the colony. Colonies are up to 2mm in diameter. The motile stage of P. globosa has a short haptonema and two flagella, both greater than the cell length. The haptonema is absent in the nonmotile stage.

Phaeocystis globosa occurs both as solitary cells and in colonies. Solitary forms differ from colonial ones in that they lack a haptonema.
