Checklist of Parasitic Isopods (Crustacea: Isopoda) Infesting Marine Decapod and Fishes Off Mexico’s Coasts

Although Rathke (1834), Dohrn (1867), van Beneden (1869), and Roule (1889, 1890, 1891, 1894, 1896) have studied the embryology of Isopoda, the first detailed account and the one that is ordinarily quoted in text-books is that of Bobretzsky (1874) on Oniscus murarius. This work is informative in a general way, though the details of segmentation and germ layer formation are not accurate. Bullar's (1878) work on the parasitic isopods was largely influenced by the generalizations of Bobretzsky. Nusbaum (1891a, 1898) and McMurrich (1892, 1895) have contributed considerably to our knowledge of segmentation and post-mandibular growth in isopods but their accounts of the different fates of the germ layers left several problems of embryology unsolved. Goodrich's (1939) studies on Porcellio and Armadillidium were confined mainly to the origin and fate of the endoderm elements. Manton's (1928) paper on the development of Hemimysis serves as a landmark in the history of Crustacean embryology.

Host Parasite

Host–parasite associations are among the primary drivers of evolutionary diversification, and hold considerable importance for understanding ecological equilibria. In particular, crustacean ectoparasites are typically associated with many fish families, and may, under certain conditions, pose threats to fisheries and aquaculture. Cymothoid isopods include blood-feeding genera that inhabit the mouth of their host, and whose variation in life-history strategies remains largely unexplored. Here we investigate the size relationship between the highly prevalent Ceratothoa italica and its main natural host, the striped sea bream, Lithognathus mormyrus. We found significant correlation between host size and that of both female and male parasites. Although the generality of a host–female size association in mouth-dwelling cymothoids had been widely recognised for some time, here we provide the first robust support for the occurrence of this size association also in mouth-dwelling male parasites. The potential underlying biological causes of the patterns are discussed, contributing to the debate on the evolution of host–parasite interactions, and the adaptive radiation of this family of parasitic isopods.
