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].

Etymology[]

The name Opercularia comes from the Latin opercularis, which means covered (with a lid).[3] This is in reference to their lid-like peristomal disk.[4]
