are predatory ciliates. However, they give very little indication of the ciliate-ness. There are, for example, normally no cilia. Instead the body produced a number of tentacles. These are mouths, and the end of the them are expanded because of a concentration of extrusomes which are used to grab hold of their food - usually other protists. Suctoria
are sessile, and only when they divide do they produce ciliated forms which then swim away and find somewhere new to settle. This form is stalked. Phase contrast.
