This family includes the slipper snails (Crepidulaspecies), theChinese hatsnails, (Calyptraeaspecies), and the cup-and-saucer snails (Crucibulumspecies) among others.
The Calyptraeidae are the only family in thesuperfamilyCalyptraeoidea.This family has no subfamilies according to thetaxonomy of the Gastropoda by Bouchet & Rocroi, 2005.
Crepidula fornicatawas transported to Europe on imported American oysters in the late 19th century and is now considered a significant pest in European oyster beds.[2]
Description
editInternally, theshellis distinguished by a shelf-like, cup-like, or half-cup-like structure used for muscle attachment. Some calyptraeids have shells that externally resemble those oflimpets,so species in the genusCrepidulaare often called slipper limpets. However, these snails are not closely related to true limpets and are more closely related toconchesandcowries.The "slipper" in the name "slipper limpet" is based on the appearance of the inside of the shell, which with its half-shelf resembles a traditional western bedroomslipper.
Reproduction
editCalyptraeids may form a tower of up to 25 animals, sometimes referred to as a mating chain. The bottom snail is always female. When she dies, the male above her will change from male to female, and the chain continues.[3]
