Persicula
Persicula is a taxonomic genus of minute to small predatory sea snails, marine gastropod mollusks. It includes several species which are micromollusks.
This genus is placed in the family Cystiscidae. It was previously in the family Marginellidae the margin snails. Both families are within the order Neogastropoda.
Habitat
Species in this genus live from the intertidal zone to 370 meters in depth.Shell description
In this genus the shell is minute to small. It can be uniformly colored or white, and the color can be patterned. The shell is moderately thick to thick. The spire is usually immersed. The lip of the aperture is thickened, and weakly to strongly lirate.An external varix can be present or absent. There is a distinct siphonal notch present and a posterior notch is also present. The columella is multiplicate, with 4 to 13 plications plus parietal lirae.
Description of soft parts
The animal has long tentacles, and the siphon is also usually long. The mantle appears not to extend completely over the external shell surface.Species
The separation between the genera Persicula and Gibberula is not well-defined. It is based on morphological differences with the larger species belonging to Persicula, while the smaller species belong to Gibberula. Many species with characteristics that fall between the two extremes, are ambiguous. Up to now there is no phylogenetic analysis to substantiate this rather arbitrary classification.According to the World Register of Marine Species, the following species with valid names are included within the genus Persicula :Persicula accola B.
