Capulidae

The Capulidae, the cap snails or cap shells, are a taxonomic family of limpet-like sea snails, marine gastropod molluscs.^[1] Capulidae is the only family in the superfamily Capuloidea. According to taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Capulidae has no subfamilies. Capulidae is assigned to the paraphyletic order Littorinimorpha,^[1] but is more closely related to neogastropods than some other littorinimorphs as it is a member of the clade Latrogastropoda.^[2]
