, the slipper snails or slipper limpets, cup-and-saucer snails, and hat snails.
This species can be distinguished from the other species of South American ''Crepipatella'' by examination of developing embryos. The females brood capsules that include both un-cleaving nurse eggs and viable embryos. The embryos consume the nurse eggs and develop into juveniles that crawl away from the capsule at hatching.
