A rare boring bivalve found at Chintsa (East London, SA)

It’s not often that the museum is presented with a pair of boring bivalves still fixed in the parent rock into which they have bored.  The species has been identified by museum malacologist, Mary Cole, as Barnea alfredensis – elongate, fragile molluscs which have penetrated a coastal sandstone as illustrated above.

The above species has a range from Table Bay (Cape Town) to East London. It is an uncommon species which does not appear to estuarine in habitat. Southern Africa has 5 species belonging to 3 genera. The genus Barnea was first described in 1826 (by Risso) and has a well developed foot in the adult.
