Crepidula fornicata is not listed under any importance categories.
|Researched by:||Will Rayment||Refereed by:||Dr Frédérique Viard|
|Phylum||Mollusca||Snails, slugs, mussels, cockles, clams & squid|
|Class||Gastropoda||Snails, slugs & sea butterflies|
|Recorded distribution in Britain and Ireland||In Britain, it is present on the east coast south of Spurn Head, the length of the south coast and northwards along the west coast to Cardigan Bay. It has been introduced accidentally to several locations in Ireland but a population has never persisted.|
|Habitat information||Crepidula fornicata is typically found attached to shells and stones on soft substrata around the low water mark and the shallow sublittoral. It is often attached to the shells of mussels Mytilus edulis and oysters Ostrea edulis.|
|Description||The shell is oval, up to 5 cm in length, with a much reduced spire. The large aperture has a shelf, or septum, extending half its length. The shell is smooth with irregular growth lines and white, cream, yellow or pinkish in colour with streaks or blotches of red or brown. Slipper limpets are commonly found in curved chains of up to 12 animals. Large shells are found at the bottom of the chain, with the shells becoming progressively smaller towards the top.|
