Parviturbo granulum is a species of sea snail, a marine gastropod mollusk in the family Skeneidae. ^[1]

Description

(Original description by W.H. Dall) The size of the shell attains 1 mm in height and breadth. The shell is elevated and compact, having ten or twelve fine strong spiral cinguli, under which are finer radiating raised incremental lines. It is white with a rounded base and a perforate umbilicus, three whorls, a nearly circular aperture, with slightly thickened or expanded margin. For so small a shell it seems remarkably solid and strong. ^[2]

Distribution

This species occurs in the Caribbean Sea off the Dominican Republic.
