Distribution and Habitat
Distribution in Britain & IrelandAll coasts of Britain & Ireland.
Global distributionRecorded from the Atlantic coasts of Europe as far north as Novaya Zemlya and south to northern Portugal and around Iceland. Also found in Greenland, Eastern coast of America down to New Jersey, Pacific coast of America, Bering Straits and Japan.
Biogeographic rangeNot researched Depth rangeSublittoral fringe to 30 m
MigratoryNon-migratory / Resident   
Distribution Additional InformationLaminaria saccharina is often found on unstable substrata such as rocks and boulders. The species is adapted to growing on these by having a flexible stipe which reduces leverage on any boulder to which it is attached, reducing the chance of its being turned over by wave movement. The species can even grow unattached and extensive populations can develop on loose-lying sand in calm conditions. In wave-exposed conditions the species may extend into the lower eulittoral.
