Colpidium Colpoda
''Colpidium colpoda'' are free-living ciliates commonly found in many freshwater environments including streams, rivers, lakes and ponds across the world. ''Colpidium colpoda'' is also frequently found inhabiting wastewater treatment plants. This species is used as an indicator of water quality and waste treatment plant performance. History and physical characteristics The first record of ''Colpidium colpoda'' was in 1829 by Mathaeo Losana, who placed it in the genus ''Paramaecia''. It was more thoroughly described by Christian Gottfried Ehrenberg in his two volume publication ''Die Infusionsthierchen als vollkommene Organismen'' (which roughly translates to “The Infusoria as Perfect Organisms”) in 1838. The species was described in detail by Ganner and Foissner in 1989. ''C. colpoda'' is considered an intermediate sized ciliate, typically between 50 and 150 μm long. The cell is roughly oval or kidney-shaped in profile, with a distinct concavity on the Anatomical terms of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ciliate
The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to flagellum, eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different wikt:undulating, undulating pattern than flagella. Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of their biological life cycle, life cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation. Ciliates are an important group of protists, common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils, including anoxic and oxygen-depleted habitats. About 4,500 unique free-living species have been described, and the potential number of extant species is estimated at 27,000–40,000. Included in this number are many Ectosymbiosis, ectosymbiotic and endosymbiotic species, as well as some Obligate parasite, obligate and Facultative paras ...

Oligohymenophorea
The Oligohymenophorea are a large class of ciliates. There is typically a ventral groove containing the mouth and distinct oral cilia, separate from those of the body. These include a paroral membrane to the right of the mouth and membranelles, usually three in number, to its left. The cytopharynx is inconspicuous and never forms the complex cyrtos found in similar classes. Body cilia generally arise from monokinetids, with dikinetids occurring in limited distribution over part of the body. Characteristics In most groups the body cilia are uniform and often dense, while the oral cilia are inconspicuous and sometimes reduced, but among the peritrichs almost the opposite is the case. Members are widely distributed, and include many free-living (typically fresh-water, but many marine) and symbiotic forms. Most are microphagous, grazing on smaller organisms swept into the mouth by the cilia, but various other feeding habits occur. In one group, the astomes, the mouth a ...
