8. Molecular analysis and biodiversity of metazoan parasites of the yellow tail lambari, Astyanax aff. bimaculatus (Teleostei, Characidae), in lower San Francisco, northeastern Brazil.

The difficulty in identifying some species of Lambaris comes from very similar phenotypic feature that often result from hybridization. The parasites can be indicative of various aspects of the biology of their hosts, including phylogeny, because some groups of parasites may have host specificity....

9. The ghost of parasites past: eggs of the blood fluke Cardicola chaetodontis (Aporocotylidae) trapped in the heart and gills of butterflyfishes (Perciformes: Chaetodontidae) of the Great Barrier Reef.

We explored the distribution of Cardicola chaetodontis in chaetodontid fishes from the Great Barrier Reef. We found just four infections of adult worms in 238 individuals of 26 chaetodontid species. By contrast, eggs were present in hearts of 75 fishes (31.5%) and 19 of 26 chaetodontid species (all ...
