The Calyptraeidae are a family of small to medium-sized marine prosobranch gastropods.[1]
This family includes the slipper snails (Crepidula species), the Chinese hat snails, (Calyptraea species), and the cup-and-saucer snails (Crucibulum species) among others.
The Calyptraeidae are the only family in the superfamily Calyptraeoidea. This family has no subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005.
Crepidula fornicata was 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
[edit | edit source]Internally, the shell is distinguished by a shelf-like, cup-like, or half-cup-like structure used for muscle attachment. Some calyptraeids have shells that externally resemble those of limpets, so species in the genus Crepidula are often called slipper limpets. However, these snails are not closely related to true limpets and are more closely related to conches and cowries. 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 bedroom slipper.
Reproduction
[edit | edit source]Calyptraeids 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]
