Adaptative Radiation of the Retina in Galaxiidae (Salmoniformes)

Australian Journal of Zoology, 1990
The retinas of seven galaxiid species collected from different habitats in Tasmania were investigated by light microscopy. There are remarkable differences between Galaxias and Paragalaxias species. The retinas of Galaxias species are characterised by a less dense retinal epithelial pigment (REP), large numbers of short and long rods, the presence of a

Ultrastructure of granulocytes of teleost fish (Salmoniformes, Cypriniformes, Perciformes)

Journal of Evolutionary Biochemistry and Physiology, 2013
Analysis of data on ultrastructure of granulocytes of freshwater and marine bony fish of orders Salmoniformes, Cypriniformes, and Perciformes showed that in all studied species there were revealed two types of granulocytes-neutrophils and eosinophils. The exception was the bluefish Pomatomus saltatrix L. whose pronephros hemopoietic tissue was found to

Comparative osteology and relationships of the Umbridae (Pisces: Salmoniformes)

Zoological Journal of the Linnean Society, 1982
The phylogenetic relationships of the five living species of umbrids are examined through a comparative osteological study based on a series of cleared-and-stained specimens of each species. The Umbridae appear to be strictly monophyletic. In addition, for 45 characters, the outgroup Esox shares one character-state with at least one umbrid species ...
