The highest ciliate ingestion rates were observed in January 2011, due to the fact that the ciliated population were numerically dominated by the group Spirotrichea (mainly Halteria grandinella), composed of small bacterivorous ciliates (usually <30[micro]m) and by the Peritrichia group (mainly represented by Campanella umbellaria and Vorticella aquadulcis-complex), composed by efficient bacterial filter feeders.

Vorticella convallaria is a polymorphic, ciliated protozoan that spends the majority of its life cycle as an actively-feeding, sessile cell attached to a substrate by its contractile stalk (Fig.
In their review of biological springs and ratchets, Mahadevan and Matsudaira (2000) describe the spasmoneme spring of Vorticella, which contracts in response to calcium signaling and can propel the cell body at speeds of about 8 cm/s.
