This species of snail has a shell which is light in color, and which can reach 5 mm in length.[1]
The shell loses its apical whorls as it grows, giving it a truncated and cylindrical appearance.[2][1]
This snail is native to areas of the northeastern Atlantic coast, from Morocco and the Mediterranean coast to the Black Sea.[1] This native distribution includes Great Britain.
There are also some early records from the late 1800s for the United States, on the coast of Newport, Rhode Island, where it was presumably introduced.[1]
This species is found in marine coastal environments, near or just above the high tide line on stones and pebbles, fine sediments and decomposing vegetation.[1] It prefers the edge of sheltered waters where the salinity is at 18-40 psu.[1][2]
The sexes are separate.[1] Fertilized eggs are laid as egg capsules, which are attached to detritus.[1][2]
