The dorsal surface, or dorsum, is the upper surface; the ventral surface or base is the lower surface bearing the aperture. Juvenile cowries appear quite different to adults; in juveniles, the shell is the typical gastropod shape with spire exposed and the outer lip thin. As the shell matures, the outer lip thickens and folds in, creating the narrow aperture of the adult shell, covering the spire in the process. In mature shells the top of the spire may not be evident, may protrude slightly, or be present within a pit at the posterior end. Most juvenile cowries are marked quite differently to the adult with a pattern of wide transverse bands, the adult colour pattern developing as the shell matures.
