Calyptraeidae
The Calyptraeidae are a family of small to medium-sized marine prosobranch gastropods.MolluscaBase. Calyptraeidae Lamarck, 1809. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=141 on ...
, 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.
