The porgies (Sparidae) comprise a diverse group of neritic fishes with a broad geographic distribution. We used mitochondrial DNA sequences from partial 16S ribosomal RNA and cytochrome b genes to reconstruct the phylogenetic history of these fishes. Sequences from 38 sparid species, 10 species in outgroups closely related to sparids, seven basal percoid species, and a non-perciform outgroup species were analyzed with parsimony and maximum likelihood. The Sparidae were monophyletic with the inclusion of Spicara, which is currently placed in the Centracanthidae. The genera Spicara, Pagrus, and Pagellus, were not monophyletic indicating a need for revision. Two main sparid lineages were recovered in all analyses, but the previously proposed six sparid subfamilies (Boopsinae, Denticinae, Diplodinae, Pagellinae, Pagrinae, and Sparinae) were not monophyletic. This suggests that dentition and feeding modes, upon which these subfamilies are based, were independently derived multiple times within sparid fishes. There was no evidence from the 16S or combined analyses for a monophyletic Sparoidea.

Background: (Günther; 1867) is a member of the family Polynemidae. The placement of Polynemidae among teleosts has varied over the years.
Methods: Therefore, in this study, we sequenced the complete mitochondrial genome of , analyzed the characterization of the mitochondrial genome, and investigated the phylogenetic relationships of Polynemidae.

The species (Cuvier, 1829) is the only representative of the family Niphonidae and the genus , and its taxonomic history is complicated; it is still unclear in a phylogenetic sense. In this study, we report the complete mitochondrial genome of (OP391482), which was determined to be 16,503 bp long with biased A + T contents (53.8%) using next-generation technology.

Corynosoma pseudohamanni Zdzitowiecki, 1984 (Polymorphidae) was described from the intestinal tract of 5 species of seals including the type and main host, the Weddell seal Leptonycotes weddellii (Lesson) in the South Shetlands, West Antarctica. Notothenia coriiceps was the primary paratenic host of 14 fish hosts reported in the original description. We describe excysted juveniles from the body cavity of the major paratenic host, Notothenia coriiceps Richardson collected off Galindez Island, Argentine Islands, West Antarctica for the first time.

Forecasting emergent pest spread is paramount to mitigating their impacts. For host-specialized pests, epidemiological models of spread through a single host population are well developed. However, most pests attack multiple host species; the challenge is predicting which communities are most vulnerable to infestation.

The worldwide distributed family Allocreadiidae Looss, 1902 is predominantly parasitic in freshwater fish and occasionally in amphibians and reptiles. It contains 15 genera, of which only Allocreadium, Creptotrema, Wallinia and Creptotrematina have been reported in Argentina. The records of Allocreadium species still require further verification.
