Habitat
Littorina saxatilis occurs from the upper eulittoral zone down to the littoral fringe of the intertidal and is typically found in crevices of bedrock, empty barnacle shells and under stones. Littorina saxatilis occurs on salt marshes on the base of Spartina species and on firm mud banks. It also occurs submerged in sheltered, brackish lagoons generally attached to Zostera, Fucus, Ruppia and Potamogeton species.
