It is the type species of the genus "Vorticella". Bacteria found on the bodies of "Vorticella" may be parasites. Vorticella convallaria is a species of ciliates. Rotifers have been observed to feed on "Vorticella". Examples include "Paramecium", "Stentors", and "Vorticella". "Vorticella convallaria" exhibits two morphological types. The contractile peristomal border closes over the disc and cilia during retraction of "Vorticella". Over 200 species of "Vorticella" have been described, although many may be synonyms. However, in 1767, it was renamed "Vorticella convallaria". The growth, development and emergence of mosquito larvae are inhibited by "Vorticella", resulting in death. "Vorticella" is one of the best-known genera. The coiled spasmoneme and batonnets serve as a molecular spring, so that "Vorticella" can contract. In terms of reproduction, "Vorticella" can undergo binary fission. "Vorticella" has an anterior peristomial lip which is short and narrow. "Vorticella" has a pellicle with striae running parallel around the cell.
