Shell: not very thick, solid, conical spire, generally high, sometimes rather flattened spires, very convex whorls and markedly impressed suture; ovoidal aperture, outer lip is not thickened or toothed, lacks inner folds; columellar lip has a fairly striking callus, partly adheres to the ventral surface of the body whorl; sculpture has almost equidistant spiral grooves and quite big axial ribs that tend to fade at the edge of the body whorl and are generally sinous; yellowish white or light hazel in color; periostracum is light chestnut in color and not very resistant; operculum is horny, smaller than the aperture, has a central nucleus. Body: large foot, whole body cream with blackish patches; head has a pair of tentacles with an eye at the base of each, long proboscis; well-developed siphon; radula is rachnioglossan.
Maximum depth from Ref. 106864. Common in the continental shelf (Ref. 106864). Common in the subtidal to 200 m depth in the northern Atlantic (Ref. 78657). Usually found on hard bottoms (Ref. 95730), as well as soft bottoms from 5 to 600 m (Ref. 106864). Also found to occur in areas with sludge (Ref. 96352). Relatively sedentary (Ref. 106864). It is a necrophagous, scavenger species (Ref. 96498). Feeds on polychaetes, molluscs, echinoderms and other smaller crustaceans (Ref. 106864). Females gather in groups to deposit eggs in a communal mass of egg capsules where veligers develop and metamorphose inside and later hatch out as young individuals (Ref. 360).
