References (not structured): Bamber RN, (1985). Coarse substrate benthos of Kingsnorth outfall lagoon, with observations on Petricola pholadiformis Lamarck. Central Electricity Research Laboratories Report TPRD/L 2759/N84. Comments: P. pholadiformis bores into clay, peat, mud, sand and other soft sediments, and may therefore modify habitats. |
Salinity tolerance range (?) | Exact range: 7.5 - 35 References: Castagna M. & Chanley P., 1973. Salinity tolerance of some marine bivalves from inshore and estuarine environments in Virginia waters on the western Mid-Atlantic coast.

Westernhagen (Eds) Warnsignale aus der Ostsee. Parey Buchverlag, Berlin: 146-150 Comments: the species in its native range inhabits environments with salinities between 29 and 35 ppt, while in the Baltic Sea it is reported from salinities 10-30 ppt (Gollasch and Mecke, 1996). According to Castagna and Chanley (1973), the lower salinity tolerance of P. pholadiformis is 7.5-10 ppt |
Habitat modifying ability potential (?) | Autogenic ecosystem engineers References: www.cabi.org Comments: Ecosystem change, habitat alteration, modification of natural benthic communities, reduced native biodiversity |

Known measurable environmental impact? | Known References: Cohen, A. N., Carlton, J. T. 1995. Nonindigenous aquatic species in a United States estuary: a case study of the biological invasions of the San Francisco Bay and Delta. Comments: P. pholadiformis may displace native species of boring bivalves. This has happened in Belgium and the Netherlands, where it has almost completely replaced the indigenous white piddock (Barnea candida). P. pholadiformis bores into clay, peat, mud, sand and other soft sediments, and may therefore modify habitats. |
