Description
A small, cap-shaped marine gastropod shell, commonly known as a slit limpet. It features a conical profile with an anterior notch (emargination) and a distinctive reticulate sculpture formed by strong radial ribs and concentric growth lines. The surface is often granular or nodulose, as visible in the image. The shell is typically off-white to cream in color, sometimes with encrustations.
