Calyptraeidae, or the slipper shells, are a taxonomic family of small to medium-sized sea snails, marine prosobranch gastropod molluscs. This family includes the slipper snails, the chinaman's hat snails, the cup and saucer snails and others.
[edit] Shell description
Calyptraeids have shells that sometimes externally resemble those of limpets, but the family is not at all closely related to the true limpets; instead they are in the order Sorbeoconcha, and are more closely related to conches and cowries.
Although the outside of the shell can be somewhat limpet-like, inside the shell, calyptraeids are distinguished by a shelf-like, cup-like or half-cup-like shelly structure, which serves for muscle attachment.
