Fossarina picta is a species of very small sea snail, a marine gastropod mollusc or micromollusk in the family Trochidae, known as the top snails.[1]

Description

[edit]

The shell grows to a length of 4 mm. The shell is depressed and turbinate, bearing a strong resemblance to Fossarina patula, though its spiral lirae are uniform and straightforward. The shell comprises four convex whorls, with a particularly sizable body whorl sporting a rounded margin. The lips are sharp and arcuate, while the aperture takes on a near-circular shape. The overall shell outline leans toward being more orbicular. Irregular purple-black radiating blotches are present on the shell, and the umbilical region typically displays a pale yellow hue.[1]

Distribution

[edit]

This marine species occurs off the coat of South Korea and Japan.
