- Cerithidea
- A genus of marine and brackish water operculate (prosobranch) snails that serve as first intermediate hosts of a number of trematodes. C. cingulata serves as host for Heterophyes heterophyes in Japan and Southeast Asia; C. scalariformis for cercariae that induce swimmer's itch in the southeastern U.S. from Florida to Texas.
