Euspira napus is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails.
Description
The diameter of the shell varies between 30 mm and 40 mm.
The shell is rounded, solid, and smooth, with a low spire. Its aperture is semi-circular, bordered by a thin outer lip, while the base features a distinct yet narrow umbilicus and a slightly thickened edge on the inner lip. The surface sculpture consists of fine, closely set growth lines. The living animal has a horny operculum.
The shell is white, with a dull brown periostracum (a thin, skin-like outer covering), typically displaying a pattern of fine spiral lines.
Distribution
This species is endemic to South Africa and occurs off Port Alfred and the Agulhas Bank (False Bay to western Transkei) at depths between 50 m and 210 m.
