Vorticella
Encyclopedia : V : VO : VOR : Vorticella
Vorticella is a genus of protozoa, with over 100 known species. They are stalked bell-shaped ciliates, placed among the peritrichs. Each cell has a separate stalk, which contains a contracile fibril called a myoneme. When stimulated this shortens, causing the stalk to coil like a spring. Reproduction is by budding, where the cell undergoes longitudinal fission and only one daughter keeps the stalk.
Some of the most common species include:
- Vorticella campanula
- Vorticella citrina
- Vorticella communis
- Vorticella convallaria
- Vorticella floridensis
- Vorticella limnetis
- Vorticella marina
- Vorticella microstoma
- Vorticella monilata
- Vorticella patellina
- Vorticella similis
- Vorticella smaragdina
- Vorticella sphaerica
- Vorticella striata
- Vorticella submicrostoma
- Vorticella utriculus
