s with approximately 400 species described, although many of these descriptions are no longer valid. It is often very difficult to distinguish between different ''Chaetoceros'' species. Several attempts have been made to restructure this large genus into subgenera and this work is still in progress.Tomas, C. R., Hasle G. R., Syvertsen, E. E., Steidinger, K. A., Tangen, K., Throndsen, J., Heimdal, B. R., (1997). ''Identifying Marine Phytoplankton'', Academic Press.Rines J. E. B., Theriot E. C., (2003). ''Systematics of Chaetocerotaceae (Bacillariophyceae). I. A phylogenetic analysis of the family'', Phycological research 51: 83–98. However, most of the effort to describe species has been focused in boreal areas, and the genus is cosmopolitan, so there are probably many tropical species still undescribed.J.E.B. Rines, P. Boonruang and E.C. Theriot., (2000).'' Chaetoceros phuketensis sp. nov. (Bacillariophyceae): a new species from the Andaman Sea''. Phycological Research 48 (3): 161–168. Some species are known from the fossil record, from the Quaternary of Sweden. It is the type genus of its family.

Description

The genus ''Chaetoceros'' were first described by Ehrenberg in 1844.
Cells are more or less rectangular in girdle view.
Cells are usually elliptical in valve view.

has four siliceous processes called mushrooms or thorns that allow them to stay together forming colonies. ''Chaetoceros'' is primarily a marine genus, but there are also accounts of species within inland waters of the United States. It is a type of centric

that contains a frustrule or cell wall composed of silica that contain long, thin spines (setae). The spines connect the frustules together creating a colony of cells.Spaulding, S., and Edlund, M. (2008). Chaetoceros. In Diatoms of the United States. Retrieved October 19, 2017, from http://westerndiatoms.colorado.edu/taxa/genus/Chaetoceros Cells colonies can form chains that are coiled, straight, or curved. Cell size can range from <10 um to 50 um.

Beneficial effects

Due to its high growth rates, research has been conducted to potentially use of ''Chaetoceros'' in biotechnology. Some ''Chaetoceros'' species are well-established commercial aquacultures. Many of them are recognized as generally good producers of useful lipids and other biologically active products with high value-added. They have enormous potential for producing nutraceuticals and biofuel. Studies suggest that colonies of ''Chaetoceros'' serve as an important food source within the water column and major carbon contributor to the benthic environment. Within the North Water, located in northern Baffin Bay, ''Chaetoceros'' has been reported to contribute about 91% of total phytoplankton cells serving as an important primary producer within this area. Therefore, contributing to oxygen production in the North Water. Overall,

phytoplankton Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Ph ...

contributes to over half of Earth's oxygen production.

Blooms

''Chaetoceros'' blooms have been reported to reach concentrations of 30,100 cells/ml and can persist for multiple months. Blooms are able to persist because individuals can survive at low nutrient levels. When present in large quantities, species with larger, thicker spines can damage organisms' gills.Kraberg, A., Baumann, M. and Durselen, C. D. 2010. Coastal Phytoplankton: Photo Guide for Northern European Seas. Verlag Dr. Friedrich Pfeil, Munchen, Germany. 204. Although, this defensive trait can help the species avoid predation and further promote bloom success. Overall, intensive development of the species of the genus ''Chaetoceros'' in the Arctic Ocean has a significant impact on the biogeochemical cycle of organic carbon and silicon, as well as on a wide range of macronutrients, trace and rare earth elements.
