The motile organs consist of an adoral zone of membranelles, which stretch along the left edge of the peristome and the front edge of the body.
The lines of cilia converge at the mouth, and at this region the cilia are somewhat larger and more distinct, thus forming a functional adoral zone.
The peristome is well-marked by the adoral zone, and upon its right border there is a row of cilia, and a similar row of cilia runs along the base of the oral membranelle.
