Habitat: mainly it lives on algae, in the circalittoral and deep infralittoral zones.
Distribution: it can be found all over the Mediterranean, but never common. Rarer in the Eastern sector. Notes: shell slim in form, turriculate, quite clear suture, incised, whorls a little bit convex, surface smooth. Narrow in aperture, sub-quadrangular, quite clear siphonal canal, external lip thickened and denticulated internally. At the base there are some spiral little cords quite broad. Sometimes on columella there are weak folds. Apex smooth, obtuse, usually brown in colour. Either yellowish or uniform light brown in colour, sometimes also greenish. Periostracum, thin but strong, is a little bit darker than the shell. There can be also found specimens with darker thin little axial lines. Differently from other Mediterranean similar ones, this species has a siphonal canal short but distinct and for this peculiarity it was set up in the genus Columbellopsis B.D.D., 1882 for a long time. Once adult it maintains integral the first whorls of spiral. The slim outline and the uniform colour make easily recognizable the juvenile forms too. The adult specimens average measures are around 10-12 mm in height.
