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

Description

The shell grows to a length of 4 mm. The depressed, turbinate shell is very similar to Fossarina patula, but the spiral lirae are equal and simple. The shell contains four convex whorls. The body whorl is large with a rounded margin. The sharp lips are arcuate. The aperture is nearly circular. The outline of the shell is more orbicular. The shell is marked with irregular purple-black radiating blotches. The umbilical region is generally pale yellow.[1]

Distribution

This marine species occurs off South Korea and Japan.
