Cypraeidae, commonly known as cowries, are a family of marine gastropod mollusks. They are characterized by their glossy, often brightly colored shells, which are smooth and oval-shaped. Cowries inhabit warm, shallow waters and are found in tropical and subtropical regions around the world. These mollusks play a significant role in their ecosystems, serving as both herbivores and prey for various marine animals. Cowries have a unique feeding mechanism, using a specialized radula to graze on algae and other organic materials. Their shells have also been historically used as currency and in jewelry, making them culturally significant in many societies.
