Nassarius arcularia (Linnaeus, 1758)
Nassarius arcularia is a shell snail from the family Nassariidae, which is colloquially known as pot snails. The very extensive family mainly includes small snails with a worldwide distribution and are usually found in large colonies in the intertidal area on soft bottoms. Fish snails are scavengers.
The shell size of Nassarius arcularia varies between 18 mm and 40 mm. The ovoid, ventricose shell is quite thick. The color of the casing is ash-gray, but sometimes bluish, and is decorated with one or more transverse white or brown bands. Another brown band always extends between the tubercles of the body vertebra. The operculum is oval and round, membranous and serrated on one of its edges.
The coloring varies equally, some specimens are completely white. Others are a uniform reddish or maroon color. The young of this species have much more pronounced wrinkles and stripes.
