In laboratory cultures, where larvae of such bivalves as oysters and clams were kept together with large ciliates of the family Condylostomidae, the latter were seen ingesting the larvae. A single Condylostoma could contain as many as six larvae. Related species may destroy many bivalve larvae in nature.
