Rhabdostyla (rab-doe-style-a) a peritrich ciliate, attached to the substrate by the posterior end of the cell, but not with a differentiated stalk. Feeding cilia located as a wreath at the anterior end. The long dark bodies within these cells are their macronuclei. Phase contrast.

Rhabdostyla (rad-doe-stile-a) are solitary peritrich ciliates with a very short noncontractile stalk. The body is mostly inverted bell-shaped. The peristome shows a definite lip. Some species of the genus live epizooic on freshwater invertebrates, particularly crustacea, insects and worms. This genus can be confused with Apiosoma which is restricted to being epizooic on vertebrates. Rhabdostyla inclinans is an epizooic species and this cell was attached by a short stalk to the bristle of a worm. Differential interference contrast.

Rhabdostyla, peritrich ciliate attached to substrate by non-contractile stalk. The oral ciliate forms a wreath around the anterior end, the inner wreath being an extended membranelle, the outer one being the undulating membrane.
