Description
A small to medium-sized cowrie, commonly known as the Hawaiian Cowrie. The image displays the living animal with its mantle fully extended, largely obscuring the shell. The mantle is a very dark brown to black, densely covered with numerous small, often white-tipped papillae, giving it a textured, frilly appearance along its edges. A small portion of the shell is visible, revealing a reddish-brown base color adorned with distinct white spots. The animal is observed nestled within a crevice or depression on a rocky or coralline substrate, surrounded by pinkish encrusting organisms, indicative of its natural habitat.
