Adult digenetic trematodes are typically parasites of vertebrates. Sexually mature trematodes occurring in invertebrate hosts are usually regarded as precocious last-larval stages, to which the term 'progenetic' is applied. These progenetic forms are often encysted, and can usually only contribute to the further life history of the species, and, in many cases, can only attain the definitive for...

We explore the correlational patterns of diet and phylogeny on the shape of the premaxilla and anterior tooth in sparid fishes (Perciformes: Sparidae) from the western Mediterranean Sea. The premaxilla is less variable, and in spite of the presence of species-specific features, a common structural pattern is easily recognizable in all species (i.e. the ascending and the articular processes are ...

The aim of this work was to present a preliminary knowledge of the parasitic copepods of marine fish of Turkey. In this study, four parasitic crustaceans were reported from five different fish species found in Turkish seas: Lepeophtheirus europaensis (Zeddam, Berrebi, Renaud, Raibaut & Gabrion, 1988) was found on the gills of the European flounder, Platichtys flesus (Linnaeus, 1758 (Pleuronecti...

ABSTRACT Fish are considered one of the important sources protein which invaded by different parasites. This study aimed to shed light on monogenean parasites that infect fish within family Sparidae in Saudi Arabia. A total 30 Argyrops filamentosus specimens were collected from Red Sea, city Jeddah (Saudi Arabia), and then examined for presence Parasitic species isolated studied morphologically...
