Abstract | Larval digenean parasites were studied in Littorina obtusata (L.) and L. mariae Sacchi & Rastelli at Sawdern Point in West Wales. Shell parameters, ovipositor and shell colour, penis morphology and sex ratios were scored, and the influence of parasitism studied. A total of 7 species of parasites were found, although the prevalence was very low in L. mariae, especially in the females. The parasitic gigantism that has been described in other species of gastropod was not found in this study. Parasitic castration does occur in some infected male L. obtusata, resulting in severe stunting of the penis. However, this phenomena was never observed in L. mariae. The winkle species are congeneric and inhabit broadly similar niches on the shore; their life histories are however quite different - one being annual and the other perennial. This probably affects exposure to infection, and might explain the differing prevalence of the parasites. © 1990 Kluwer Academic Publishers. |
