Global distribution	Northern Portugal and the Atlantic coast of France; British Isles, North Sea coasts and into the western Baltic; Scandinavia up to Novaya Zemlya; Iceland and the Gulf of St. Lawrence in the western north Atlantic.
Biogeographic range	Not researched	Depth range	Not relevant

Substratum preferences	Bedrock Large to very large boulders Small boulders Cobbles	Physiographic preferences	Open coast Sealoch Ria / Voe Estuary
Biological zone		Wave exposure	Moderately Exposed Sheltered Very Sheltered Extremely Sheltered
Tidal stream strength/Water flow	Strong (3-6 kn) Moderately Strong (1-3 kn) Weak (<1 kn) Very Weak (negligible)	Salinity	Reduced (18-30 psu) Full (30-40 psu) Variable (18-40 psu)
