Olivella, common name the dwarf olives, is a genus of small predatory sea snails, marine gastropod molluscs in the subfamily Olivellinae of the family Olividae, the olives. Olivella is the type genus of the family.[2]
Description
Adults in the Olivella species are usually quite small, hence the genus has the common name "dwarf olive". Species of Oliva are usually larger, but there are exceptions.
The shell of Olivella usually has a keel-like twist at the anterior end of the columella. The wall above it may be concave or have deep furrows. The inner lip can sometimes show a deep callus, and in many cases this extends over the parietal wall to the end of the aperture. This callus formation may extend to the spire but leave the suture open. Most species of Olivella have a thin, chitinous operculum, but this operculum is lacking in Olivella nivea, as is also the case in species of Oliva.
