Littorina saxatilisis a common intertidal gastropod on shores of the North Atlantic, and an important study species for evolutionary investigations. Its congenerL. arcanais much less widely distributed, but both species are common at Old Peak, Yorkshire, UK. The parasite profiles ofL. saxatilisandL. arcanafrom this shore were determined histologically, revealing a ciliated protist,Protophrya ovicola, an unidentified apicomplexan (present in <1%L. saxatilis) and three trematode parasites tentatively assigned toRenicolasp.,Microphallus similisandM. pygmaeus. The profile data include prevalence information and associated histology.Protophrya ovicolaassociated predominantly with the wave ecotype ofL. saxatilis(65%) rather than the crab ecotype (16%).Microphallus similisoccurred at a higher prevalence in theL. arcanapopulation (38%) in comparison with theL. saxatilispopulation (11%). Overall, there appeared to be a lower prevalence of trematodes in the high-shoreL. saxatilis. By modelling the occurrence of individual parasites and shell morphometrics, an assessment of parasite-associated morphological change was conducted. We conclude that parasitism appeared not to cause shell-shape change, but rather that snails of a certain shell shape were more likely to display infection. Records of parasites inL. saxatilisandL. arcanaare briefly reviewed, showing that the diversity of parasites reported here is relatively low.
