Attheya Zachariasii
''Attheya'' is a genus of small single celled diatoms. Some of these species were earlier regarded to belong to ''Chaetoceros'', or to '' Gonioceros'', the taxonomic status of some of these species are still debated.Crawford, R.M., Hinz, F. and Koschinski, P. 2000. The combination of ''Chaetoceros gaussii'' (Bacillariophyta) with ''Attheya''. Phycologia 39(3):238-244. Description They are distinguished morphologically from ''Chaetoceros'' by the structure of valve outgrowths or girdle bands. The girdle bands can only be seen with an electron microscope.Crawford, R. M., Gardner, C., Medlin, L. K. 1994. The genus ''Attheya''. I.

Diatom
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...

Chaetoceros
''Chaetoceros'' is probably the largest genus of marine planktonic diatoms with approximately 400 species described, although many of these descriptions are no longer valid.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.
