    Pholas dactylus, or common piddock, is a bioluminescent clam-like species of marine mollusc in the family Pholadidae . The piddock bores into the substrate for shelter, and lives in a tubular burrow formed by grinding the material away with hard parts of the shell by rotating on the longitudinal axis.
    Pholas dactylus bores into a wide range of substrata including various soft rocks such as chalk and sandstone, clay, peat and very occasionally in waterlogged wood. Found from the lower shore to the shallow sublittoral. Shell thin and brittle, elliptical in shape with a beaked anterior end and bulbous umbones in anterior third of shell.
    Pholas dactylus has phosphorescent properties, the outlines of the animal glowing with a green-blue light in the dark. Pholas dactylus occurs in Britain from Kent along the south and south-west coasts including south Wales, Anglesey and Solway. Also recorded from several sites on the east coasts of Yorkshire and Northumbria and southwest Ireland.
    Experimental work with Pholas dactylus showed that large fragments are either rejected immediately in the pseudofaeces or passed very quickly through the gut (Knight, 1984). An increase in the organic content of suspended sediment is likely to be beneficial to suspension feeders such as the common piddock.
