Description
A medium-sized, smooth, and highly polished marine gastropod shell, characterized by its elongate-ovate shape and short spire. The shell exhibits a light brown to tan background color adorned with darker brown axial patterns, often appearing as zig-zags or irregular blotches. A distinctive feature is the reddish-orange color visible within the aperture, likely from the columella or the animal's mantle. This specimen is shown held in a hand on a sandy beach, consistent with its typical habitat.
