While frequent intertidally on fucoids and other substrates, the species has occasionally been recorded as deep as 100 m (Cornelius 1995b). Records of L. flexuosa in western Sweden have predominantly been from very shallow waters, and it was not recorded at all in the extensive collections of Jägerskiöld (1971), most of which were obtained in deeper waters by dredging. In the nearby Oslofjord, southern Norway, it is common from the intertidal zone to a depth of about 3 m on algae and stones (Christiansen 1972). In Danish waters it is abundant where suitable substrates exist, and penetrates deep into the Baltic Sea (Kramp 1935b).
