Description
A robust, heavy, and somewhat flattened univalve shell, commonly known as the Chilean Abalone or Loco. Its exterior is characterized by prominent, irregular concentric growth ridges and is often covered with epibionts such as algae, giving it a dull appearance. The shell's shape is broadly oval to sub-quadrangular, resembling a limpet, with a low spire and a very large aperture. The specimen in the image displays a pale pinkish-white to cream base color, with noticeable green algal growth on its surface.
