Detail of the oral aperture of the colpodid ciliate, Rostrophrya camerounensis (Njine, 1979) Foissner, 1993 (yellow arrow indicates posterior end of oral aperture).This population has been feeding on filamentous cyanobacteria (Oscillatoria sp.)Collected from an ephemeral puddle near Boise, Idaho March 2005. DIC.

Detail view of the macronucleus (MA) and small elliptical micronucleus (Mi) within the macronuclear envelope (NE) in the large colpodid ciliate, Rostrophrya camerounensis (Njine, 1979) Foissner, 1993.The specimen is moderately compressed by coverglas pressure. Collected from an ephemeral puddle on an intermittently flood-irrigated grass lawn in Boise, Idaho. July 2007 DIC.

Ventrolateral view of the infraciliature of the colpodid ciliate, Rostrophrya camerounensis (Njine, 1979) Foissner, 1993. The shape of this specimen has been distorted by fixation and coverglass pressure. The relatively large obliquely oriented elliptical oral aperture (distorted in this specimen) is located at the junction of the rostrum with the main body. aperture. Collected from standing organically enriched roadside ditchwater near Boise, Idaho, March 2005.Stained by the silver carbonate technic (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield.

Somatic ciliature of the colpodid ciliate, Rostrophrya camerounensis (Njine, 1979) Foissner, 1993. There are about 80 slightly spiraled somatic kineties consisting of ciliated dikinetids (seen well in this image.
