Popis

Shell translucent, semitransparent, whorls not much convex, conic in form. The most important characteristic is the aperture small, pyriform. False suture evident, visible as one line white in colour. Last whorl, rather roundish, is little less than half of total height. Lip oblique that, whether seen laterally, seems it is inflated, without one sinus. Columella vertical, as high as about half of aperture, no siphonal canal. As it can be seen through its transparent shell, the animal is red orange in colour. In the lower part juvenile specimens have a lip more expanded and last whorl less rounded. The adult specimens average measures are around 3.5-4 mm but there is a sexual dimorphism. Usually the female is bigger.

Rozšíření

Common in a large part of the Mediterranean where it has a remarkable bathymetric diffusion: from a few tens of metres up to remarkable depths, usually in a coralligenous habitat. It lives as a parasite on sea-urchins of Cidaroida order (Cidaris cidaris).
