Description
A small to medium-sized predatory sea snail, commonly known as the Angled Oyster Drill or Subangular Oyster Drill. Its shell is characterized by a fusiform shape, prominent axial ribs, and a distinctive color pattern of whitish or cream background with reddish-brown to dark brown axial streaks. It is often found in shallow marine environments, particularly on oyster beds and rocky substrates, where it preys on bivalves.
