Nassarius globosus, commonly known as the globose nassa, is a species of sea snail, a marine gastropod mollusc in the family Nassariidae, which includes the Nassa mud snails or dog whelks. The shell is small, ovate, thick, and slightly gibbous, with a short, pointed spire composed of six slightly convex whorls. The body whorl is very large, and the ovate aperture is emarginated at the upper part, with a rather thin outer lip that is striated internally.

Background
The shell of Nassarius globosus is ovate, thick, and slightly gibbous, with a short, pointed spire. The six whorls are covered with longitudinal folds and very approximate transverse striae that form flattened granulations.
The body whorl is notably large, and the aperture is ovate, emarginated at the upper part where it meets the outer lip. The columella is arcuated and covered by the inner lip, which is enlarged into a whitish, wide, and thick callosity upon the body of the body whorl. The shell's color is reddish brown, typically with one or two transverse bands across the middle of the body whorl.
