Rapaninae

Rapaninae is a subfamily of predatory sea snails, marine gastropod mollusks in the family Muricidae.

This subfamily was known as Thaidinae until 1993.

Shell description
The shell is usually more or less pyriforra, and often produced anteriorly. The spire is short. The inner lip is convex and smooth. The shells of species in this subfamily typically do not have a varix, but strong axial sculpture is often present.

The operculum is ovate, blunt. The nucleus is elongate, forming the outer or hinder edge.
