Two Oxytrichid Ciliates, Cyrtohymena primicirrata and Oxytricha granulifera (Ciliophora: Sporadotrichida: Oxytrichidae) Unknown from Korea
This study reports the discovery of two oxytrichid ciliates, Cyrtohymena primicirrata (Berger and Foissner, 1987) and Oxytricha granulifera Foissner and Adam, 1983, in Jeju Island, Korea. The morphology of the two species was studied using live observation and protargol impregnation. These species a...

Arrangement of undulating membranes is Oxytricha pattern.
