Ventral infraciliature

Description:

Infraciliature (ventral, anterior) of the ciliate, Ophryoglena flava (Ehrenberg, 1833). The numerous closely spaced longitudinal kineties on the right and left of the oral aperture converge at a sigmoid preoral suture. At least 15 postoral kineties terminate at the oral aperture. The dense inner ciliary rows of the buccal opening are seen here as a brown crescent in the concavity of which the refractile "watchglass organelle" (Lieberkühn's organelle) is located. Collected from a freshwater pond near Boise, Idaho. Silver carbonate method (Foissner, W.Europ. J. Protistol.27,313-330;1991). Brightfield.
