Carchesium is a genus of unicellular , colony-forming bell animals (Vorticellidae) from the subclass of Peritrichia .
description
The species of the genus form colonies that are stem-branched, tree-like in shape, up to 4 millimeters high and can consist of over one hundred individuals (" zooids "). The zooids sitting at the end of a branch are bell-shaped. Each zooid has its own muoneme , which runs the entire length of its stems, but is not connected to the muonemes of the other zooids in the colony. Due to the individual myonemes, the zooids do not contract synchronously with each other. The Mundbewimperung consists of kineties at the front end of the cell, which rotate counterclockwise. Usually there is a thread-like large core . A Lorica is missing.
distribution
The species of the genus can be found in fresh and salt water alike, they colonize aquatic plants or small aquatic animals.
