Chaetoceros

Centrales Pennales

Chaetoceros er trolig den største gruppen av marine planktoniske kiselalger med omtrent 400 arter beskrevet. En stor andel av disse er riktignok ikke vitenskapelig aksepterte. Det er ofte vanskelig å skille de forskjellige Chaetoceros artene fra hverandre, noe som leder til at feilidentifisering er ganske utbredt.C.H. von Quillfeldt., (2001). Identification of Some Easily Confused Common Diatom Species in Arctic Spring Blooms. Botanica Marina Vol. 44: 375 - 389 I tillegg har det blitt gjort mange forsøk på å restrukturere denne store gruppen, men dette arbeidet er langt fra ferdigTomas, 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. Mesteparten av forskningen som har blitt gjort på denne verdensomspennende gruppen har vært konsentrert i boreale områder, dermed er det trolig et stort antall tropiske arter som enda ikke har blitt beskrevet.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.

Beskrivelse Gruppen Chaetoceros ble først beskrevet av Ehrenberg i 1844. Cellene er mer eller mindre rektangulære sett ovenfra, og litt mer ovale sett fra siden. Setaene til celler i kjede er sammenføyde ved utgangspunktet til setaene.
