Nassarius pauperatus, common name the impoverished dog whelk, is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the Nassa mud snails or dog whelks.^[1]

Description

The length of the shell varies from 12 mm to 20 mm.

The ovate, conical shell is pointed at the summit. The pyramidal spire is formed of six or seven distinct, smooth, convex whorls. These are covered with very prominent, convex, longitudinal folds, intersected only at the base, and upon the two or three upper whorls, by a few pretty deep transverse striae. Upon these whorls the striae become finer and more approximate. They rarely exist upon the whole surface. In like manner the longitudinal folds do not appear upon the right portion of the body whorl. The color is of a violaceous white. A dark red zone borders the suture, and a broader and browner band surrounds also the middle of the body whorl.^[2]

Distribution

This marine species is endemic to Australia and occurs off New South Wales, South Australia, Tasmania, Victoria, Western Australia.
