Aspect : despite the resemblance, they are neither Cypraeidae nor Ovulidae, but are very closely related to Velutinidae; small shell measuring 0.5–1.1 cm; globose and cowry-like in overall shape and generally striated; silky surface rather than highly glossy, with subdued colors—usually white, pink, or pale with subtle spots or bands

Feeding : carnivorous (sea squirts and colonial tunicates)

Environment : worldwide tropical to temperate marine environments, from intertidal zones to depths exceeding 1,000 m, often attaching to rocks, coral reefs, or burrowing in sand and mud substrates
