Oligohymenophorea
Sign in to saveThe 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.

Oligohymenophorea – liczna gromada orzęsków. Organizmy zaliczane do tej gromady charakteryzują się posiadaniem wyspecjalizowanego orzęsienia adoralnego otaczającego cytostom. W skład tego orzęsienia wchodzi błona falująca, utworzona przez jeden szereg kinetosomów oraz membranelle, penikulusy lub polikineta. Przykładowymi przedstawicielami Oligohymenophorea są rodzaje: pantofelek (Paramecium) wirczyk (Vorticella) Tetrahymena

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 and associated structures have been lost altogether.
