Aesopus clausiliformis explained

Aesopus clausiliformis is a species of sea snail, a marine gastropod mollusk in the family Columbellidae, the dove snails.

Description

The size of an adult shell varies between 10 mm and 15 mm.

The small, spindle-shaped shell boasts a chestnut hue. It is covered with numerous fine, transverse striations. The spire comprises nine slightly convex whorls, with the upper ones featuring longitudinal plaiting. The sutures are quite prominent, bordered by small, elongated black and white spots. The brownish aperture is narrow and ovate. The outer lip is thin, delicately striated within, while the columella is slightly arcuate and smooth, forming a small siphonal canal that is emarginated at its base. ^[1]
