Cafeteria roenbergensis
''Cafeteria roenbergensis'' is a small bacterivorous marine flagellate. It was discovered by Danish marine ecologist Tom Fenchel and taxonomist David Patterson in 1988. It is in one of three genera of bicoecids, and the first discovered of two known ''Cafeteria'' species. Bicosoecids belong to a broad group that also includes opalinids, diatom, brown and golden algae and oomycetes, known as Heterokonta. It is found primarily in coastal waters where there are high concentrations of bacteria on which it grazes. Its voracious appetite plays a significant role in regulating bacteria populations.〔
==Physiology==
''Cafeteria roenbergensis'' is a slightly flattened, kidney-shaped bicosoecid. Its cell typically measures between 3 and 10 µm and it has a volume of around 20 µm3. It is colorless and has two unequally sized flagella. The smooth flagellum, angled posteriorly, is shorter, and attaches to substrates in non-motile cells, but trails behind in motile cells. The hairy flagellum points forward in an arc in sessile cells. ''Cafeteria'' is a eukaryotic organism, so it contains the typical organelles such as mitochondria and nuclei.〔
''Cafeteria roenbergensis'' reproduces asexually via binary fission,〔 first replicating the flagella and internal organelles before the cell divides. No sexual activity is known for this species. Cells can replicate in under 10 hours.
