The rocks in Cornwall are often too hard for this striking rock boring mollusc, so it is a rare find in the county. The shell itself is beautiful marked but it is also quite fragile, and easily broken. Shells are found on the south coast where there are softer rocks e.g. around St. Austell Bay, Helford Passage and Mounts Bay, where they are found in degraded Mylor Slate, fossilised timber and submarine peat deposits.

Photographs were taken in the St. Austell Bay Area of Cornwall, where new sites for this species have recently been found; and at Chyandour Rocks, Penzance, Cornwall.

Scientific and European Names:
Pholas dactylus, Common piddock, Gewone boormossel, Pholade, gite, Grande pholade, Dattelmuschel, Grose bohrmuschel, Dattero bianco.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project recommends the following websites and works with the following bodies and organisations.

Conchological Society of Great Britain and Ireland

The Conchological Society of Great Britain and Ireland
Helping to understand, identify, record, and conserve molluscs.

Marine Biological Association MBA

The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.

CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders

The CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders is an independent umbrella organisation supporting independent recorders and recording groups in the county of Cornwall.

Cornish Biodiversity Network

The Cornish Biodiversity Network
or CBN is the largest open source wildlife database in Cornwall that sends open source data to the NBN (National Biodiversity Network). It is a new recording system based on the ERICA database, the largest recording resource in Cornwall. The CBN best supports the activities and needs of the independent recording community and recording groups in Cornwall.

NBN National Biodiversity Network

The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.

The taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.

Species records published on APHOTOMARINE may not be used on any database, list or distribution map, without a signed user agreement. Cornish records that appear on APHOTOMARINE are recorded using the ERICA database to benefit recording in Cornwall and scientific and historical recording in general. No financial benefit must be taken from any record produced by David Fenwick, records are of educational benefit only. Records by David Fenwick must ''never'' be financially traded.

Pholas dactylus Common Piddock
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.
