Hastula augers have bullet-shaped shells with a pointed apex. The Shiny Auger, Hastula hastata (Gmelin, 1791), has a glossy shell surface associated with a sculpture of relatively faint axial (“vertical”) ribs. Augers are found in the sand close to the water edge, in medium- to coarse-sand habitats, where they feed on marine worms.
