Species of ciliate From Wikipedia, the free encyclopedia

Opercularia is a genus of freshwater, colonial, sessiline peritrich ciliates. As consumers of free bacteria in the water, several species of Opercularia serve as important indicator organisms in the study of wastewater treatment[1]. Operculariids can be distinguished from other sessile peritrichs (many of which share very similar body plans) by their prominent, non-contractile stalk; peristome without lip; and elongate, horseshoe-shaped macronucleus[2].
