Taxonomy: Eukaryota | Stramenopiles | Bacillariophyta | Coscinodiscophyceae | Thalassiosirophycidae | Thalassiosirales | Thalassiosiraceae | Thalassiosira | Thalassiosira pseudonana Comment: Thalassiosira pseudonana is an unicellular algae, a diatom. Diatoms are found in almost all aquatic enviroments in the world. They have been well studied in both their natural habitat and in laboratory settings. Diatoms grow an outer silica shell, called a frustule, that is unique to each species. The silica shell can be preserved, and fossil frustules can be seen in sedimental layers as early as the Jurassic/Cretaceous period. Marine diatoms sequester large amounts of carbon, and are an important model organism for studies into the biology of oceanic carbon sequestration. Diatoms also furnish a significant portion of the world's oxygen supply. The removal of CO2 from surface water is also of interest.
