The Campaniloidea are a group of marine gastropods united by sperm morphology, with members having a euspermatozoon containing seven or eight stright mitochondria, accompanied by a dense segmented sheath. They also share a simple larval shell morphology (Ponder et al. 2008). The Campaniloidea are largely relictual in the modern fauna, with Campanilidae and Ampullinidae each being represented by only a single surviving species, together with the living genus Plesiotrochus.
