Pehnacovolva rosea
From the Ovulid Family, also sometime known as fake cowries, the Spindle cowries lives on the soft corals that it eats. The colour patterns of their mantles closely resemble the prey species leading to remarkable camouflage. This is due to the phenomenon of "alimentary homochromy" (obtaining the same color as the host by feeding on the host).
