Vorticella Campanula does not move freely because it is usually found fixed aborally by its long highly contractile stalk. However, with the help of stalk and myonemes, the bell sways to and fro in the surrounding water like a flower in a breeze. The individuals of a group move in their own way.

How does a Vorticella move around?

Vorticellas reproduce by longitudinal fission. One of the two daughter cells retains the original stalk; the other grows a temporary wreath of cilia at the aboral end and migrates. Propelled by these cilia, the migrant eventually grows a stalk, attaches to a substrate, and loses its temporary cilia.

Does Vorticella move on its own?

Given that they do not move/swim around freely, Vorticella will largely depend on material moving freely in their environment for food. This includes other smaller protozoa, bacteria and other tiny organic material around them.
