A distinctive specimen of Pleurotomaria westralis, belonging to the remarkable Pleurotomariidae family.

Measuring 90 mm and weighing 30 g, this shell displays the broad, rounded form and stepped spiral structure typical of slit shells. The surface is covered with fine concentric growth lines and shows a soft palette of pale cream, ivory and light grey tones, giving the specimen a particularly elegant and understated appearance.

The characteristic slit along the outer lip is clearly visible and represents one of the defining features of the Pleurotomariidae. This unusual shell architecture, combined with the family’s ancient evolutionary lineage, makes slit shells especially interesting to collectors.

Originating from Australia, this specimen has a refined sculptural quality and a clean, almost minimalist coloration that gives it strong decorative appeal as well as scientific interest.
