Chaetoceros is a genus of diatoms in the family Chaetocerotaceae, first described by the German naturalist C. G. Ehrenberg in 1844. [1] Species of this genus are mostly found in marine habitats, but a few species exist in freshwater. [2] It is arguably the common and most diverse genus of marine planktonic diatoms, [3] with over 200 accepted ...
The Coscinodiscophyceae are a class(s) of diatoms. [1] They are similar to the Centrales, a traditional, paraphyletic subdivision of the heterokont algae known as diatoms. [2] [3] [4] The order is named for the shape of the cell walls (or valves or frustules) of centric diatoms, which are circular or ellipsoid in valve view.
The payara, which is also sold as the saber tooth barracuda, vampire fish, vampire tetra, or saber tusk barracuda, is a popular species for large, aggressive aquariums. It requires a large aquarium and can only be mixed with relatively large species, as smaller will be seen as potential prey. [4]
Chaetocerotaceae is a diatom family. [2] Chaetoceros is perhaps the largest and most species rich genus of marine planktonic diatoms. The taxonomic status within Chaetocerotaceae at present is somewhat unclear.
Didymosphenia geminata is a diatom, which is a type of single-celled organism unique for their silica (SiO 2) cell walls. The life history of diatoms includes both vegetative and sexual reproduction, though the sexual stage is not yet documented in this species.
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
Bacteriastrum is a widely distributed marine, planktonic genus. This genus is often associated with Chaetoceros but differs in radial symmetry and fenestration of setae. The colonies tend to lie in girdle view, and the cells are separated by the curvature of the basal part of the setae, leaving a small gap between the cells.
Coscinodiscus is a genus of centric diatoms in the family Coscinodiscaceae. It is the type genus of its family. There are over 200 species of Coscinodiscus. [1] Coscinodiscus argus Ehrenberg 1839 is the type species of this genus. [2]
