Symbiosis between the pea crab Dissodactylus primitivus and its echinoid host Meoma ventricosa: potential consequences for the crab mating system
In many symbioses involving marine crustaceans the nature of the relationships and the population biology remain overlooked, obscuring the understanding of their ecology and evolution. The… Expand
Asymmetric exploitation of two echinoid host species by a parasitic pea crab and its consequences for the parasitic life cycle
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… Expand
No evidence of host specialization in a parasitic pea-crab exploiting two echinoid hosts
The pinnotherid crab Dissodactylus primitivus lives parasitically on 2 burrowing echinoid species, Meoma ventricosa and Plagiobrissus grandis. The fecundity of female crabs varies between hosts, and… Expand
Chemical host detection and differential attraction in a parasitic pea crab infecting two echinoids
Mechanisms of host detection and host choice are important for mobile parasites or symbionts that frequently move among host individuals. The parasitic pea crab Dissodactylus primitivus is an… Expand
Should I stay or should I go? Causes and dynamics of host desertion by a parasitic crab living on echinoids.
In some long-living symbiotic species, movements between hosts are not limited to offspring since adult parasites can move from one individual host to another one. Host-switching may be driven by… Expand
Genetic and morphological differentiation of the crab Dissodactylus primitivus, ectoparasite of two sympatric echinoids
