Biogeographic rangeNot researched Depth rangeNot relevant
MigratoryNon-migratory / Resident   
Distribution Additional InformationPaludinella litorina is probably under-recorded due to its small size, inaccessible habitat and the similarity of its shell to that of Littorina saxatilis. An update on the distribution of Paludinella litorina has been compiled by Light & Killeen (2001). Frequent molluscan associates are the pulmonate Otina ovata in the crevice or cave habitat, and the pulmonates Ovatella myosotis and Leucophytia bidentata and prosobranch Truncatella subcylindrica in shingle interstices. Other species particularly associated with Paludinella litorina are the Isopoda Ligia oceanica in cave habitats (unless Ligia oceanica is excessively dominant, then Paludinella litorina is excluded), and Bdella mites in the interstitial habitat of the upper shore shingle or boulders (Light & Killeen, 2001).
