Rissoina punctostriata is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Rissoinidae.[1]
Description
The shell is small, white, elongate-conical, and relatively thin, measuring approximately 5-10mm in length and 2.5-3.5mm in width. The protoconch consists of three spiral smooth whorls, with the final whorl having a diameter of about 400 µm, indicating a plankotrophic type larval development. A spiral cord appears in the middle of the last quarter of the final whorl.
The teleoconch consists of 6-7 whorls. The first 3-4 spire whorls are distinctively angulated, while subsequent whorls become gradually convex. The suture is shallow with a subsutural depression that gradually becomes more pronounced on later whorls, creating a slightly undulating profile.[2]
Distribution
This species occurs in the Atlantic Ocean off Mauritania, Senegal, Angola, the Cape Verdes, São Tomé and Príncipe.
