Images of shells from a private collection in Cornwall.

I do not know if there are any record from Devon and Cornwall, but the species is found on the south coast of Britain. It is included here because of its similarity to the White piddock, Barnea candida.

Scientific and European Names:
Petricolaria pholadiformis, Gastranella tumida, Petricola carolinensis, Petricola flagellata, Petricola fornicata, Petricola pholadiformis, American piddock, False angel wing.

Location information provided by the author and from the ERICA records database for Cornwall. Scientific and Common Names used are largely gained from from the WoRMS Database.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
