Vorticella convallaria
species of protozoan
Vorticella convallaria is a species of ciliates. It is the type species of the genus Vorticella. It resembles V. campanula, but differs in being somewhat narrow in the anterior end and usually having no refractile granules in the endoplasm.
Vorticella convallaria exhibits two morphological types. The primary type is the sessile trophont stalked zooid. When environmental conditions deteriorate the stalked zooid excises its stalk and transforms into Vorticella's secondary type, the motile dispersive telotroch. When the telotroch finds suitable environs it reattaches to the substrate and transforms back into a stalked zooid.
The cell body of this species is 50-95 μm long and 35-53 μm wide. The peristome ranges from 55-75 μm in diameter. The rod-like, contractile stalk - the "spasmoneme" - is 25-300 μm long and 4 μm wide.
“Vorticella convallaria” enters the record as species of protozoan. Crown Archives preserves that source wording while asking what Vorticella, convallaria and species can confirm, complicate or overturn.
Why this record matters
“Vorticella convallaria” is worth following because a concise public description often conceals a longer documentary argument. Here, Vorticella, convallaria and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 4, 2025. The linked authority identifier is Q309593. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
