Diatoms[5] are a major group of algae, and are among the most common types ofphytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stars (e.g. Asterionella). Diatoms are producers within the food chain. A unique feature of […] read more

Chaetoceros is probably the largest genus of marine planktonic diatoms with approximately 400 species described. Although a large number of these descriptions are no longer valid. It is often very difficult to distinguish between different Chaetocerosspecies.[1] Several attempts have been made to restructure this large genus into subgenera and this work is still in progress[2][3]However, most of […] read more

Sargassum is a genus of brown (class Phaeophyceae) macroaldga (seaweed) in the order Fucales. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs. However, the genus may be best known for its planktonic (free-floating) species. While most species within the class Phaeophyceae are predominantly cold […] read more

Phytoplankton (English pronunciation: /ˌfaɪtoʊˈplæŋktən/) are the autotrophic component of the plankton community. The name comes from the Greek words φυτόν (phyton), meaning “plant“, and πλαγκτός (planktos), meaning “wanderer” or “drifter”.[1] Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, they may appear as a […] read more
