Life Cycle: "The Ciliophora are characterized by the possession of two types of nucleus, the sexual process of conjugation, a basically equatorial division plane in binary fission, and a form of pellicular organisation in which cilia and their intracellular attachments (the infraciliature) are dominate features" (Sleigh, 1989).
The cytostome of vestibuliferans lies within an apical, subapical, or occasionally posterior, vestibular depression containing modified somatic ciliature associated with a rhabdos-type cytopharynx.
