Exploitation of more than one host species may increase fitness of parasites, but it also shapes their life cycle and evolution. During its post-metamorphic stages, the pea crab Dissodactylus primitivus parasitizes the echinoids Meoma ventricosa and Plagiobrissus grandis with high preva- lence. However, the present study provides evidence that P. grandis is infected by adult crabs only, attesting to an unusual asymmetry in host exploitation. Because of its low population densities, P. grandis… Expand
