Vasum, common name the vase snails or vase shells, is a genus of mostly rather large predatory sea snails, marine gastropod mollusks in the subfamily Vasinae within the family Turbinellidae.

Shell description

Shells of species in this genus are usually somewhat large, and are usually very thick and heavy. They are often vase-shaped, in the sense that the shell of most of the species is more or less widely conical. The shells have a thick periostracum, a low spires, and 2, 3 or 4 plaits on the columella.

The shell is oval, oblong, solid, tubercular or spinose, with spinose fascicles below. The spire is short. The apex is not papillary. The aperture is oblong. The siphonal canal is short and somewhat recurved. The columella contains several transverse folds in the middle. The outer lip is thickened and sinuous.

The animal (of Vasum) is slow-moving, timid and inactive, shrinking quickly within the shell on the slightest alarm. The operculum is ovate, acute, with an apical nucleus; it is very thick, claw-like, and partially free at the hind part. The dentition resembles somewhat that of the Buccinidae, differing in the lateral teeth; it differs widely from the Nassidae, and quite as much from that of the Fasciolariidae

Species of this genus are circumtropical; also off Australia (Northern Territory, Queensland, Western Australia)
