Triviella
Triviella, common name the smooth pearl cowries, is a genus of small sea snails, marine gastropod molluscs in the family Triviidae, the trivias.
Characteristics
The genus *Triviella* includes several species that are highly similar and often require microscopic examination of the live animal for accurate species-level identification. The shells of smooth pearl cowrie species are inflated and globular, with a thickened labrum that features well-developed denticles. These denticles often extend as transverse ridges around the outer lip, occasionally reaching the lower lateral part of the dorsum. Additionally, the inner lip of the aperture is also denticulate.Species
