Vitellogenin diversity in the perciformes
Journal of Experimental Zoology, 1992AbstractVitellogenin variation was studied in 11 species of Perciformes encompassing the families Cichlidae, Serranidae, Lutjanidae, Centropomidae, and Eleotrididae. Despite the enormous morphological and ecological diversity that characterizes this order of teleosts, northern blot analysis revealed that the Oreochromis aureus vitellogenin gene probe ...

Iron in the Enameloid of Perciform Fish
Journal of Dental Research, 1992It is known that a high concentration of iron is deposited in the enameloid of some teleostean fish. Previously, Suga et al. (1989) pointed out that the iron concentration in the enameloid is related to the phylogeny of fish rather than to the feeding habits, according to the results of quantitative iron analyses on the teeth of marine teleost fish of

A revision of the Emmelichthyidae (Pisces : Perciformes)
Marine and Freshwater Research, 1977The marine fish family Emmelichthyidae is redefined to include only the genera Emmelichthys (four species), Erythrocles (four species) and Plagiogeneion (two species). Two new species of Emmelichthys from the Pacific Ocean are described. Emmelichthys nitidus Richardson is divided into two subspecies: E.

Ichthyological Research, 2005
The phylogenetic relationships of the family Trichodontidae and suborder Cottoidei (and zoarcoid Bathymasteridae) are reconstructed morphologically. The monophyly of the Trichodontidae, Cottoidei, and Zoarcoidei is unambiguously supported by 14 synapomorphies, including 1 newly recognized (and also 4 synapomorphies when ACCTRAN is accepted).

Cytotaxonomical consideration of the genusBlennius (pisces-perciformes)
Experientia, 1975E stato descritto il cariotipo di 7 specie di Blennidi Mediterranei appartenenti al generaBlennius L.:B. sanguinolentus, B. pavo, B. sphinx, B. trigloides, B. canevae, B. fluviatilis eB. incognitus. Il numero diploide di tutte le specie e 2n=48 tuttavia la morfologia del cariotipo presenta alcune differenze tra le specie;Blennius trigloides si ...

Molecular Phylogeny and Speciation of the Surfperches (Embiotocidae, Perciformes)
Molecular Phylogenetics and Evolution, 1999Labroid fishes include a variety of families, such as wrasses (Labridae), odacids (Odacidae), damselfishes (Pomacentridae), parrotfishes (Scaridae), cichlids (Cichlidae), and surfperches (Embiotocidae). With only 23 species, the small embiotocid family exhibits a remarkably low species diversity compared to the large species diversity of the Cichlidae.

Phylogenetic relationships of the stromateoid fishes (Perciformes)
Ichthyological Research, 2004The phylogenetic relationships of all 16 genera (plus Psenes pellucidus) of the suborder Stromateoidei were estimated cladistically based on 43 osteological, myological, and external characters. Thirty equally parsimonious trees were obtained. Based on the strict consensus tree, Centrolophidae was nonmonophyletic, Psenopsis being placed as a sister ...

Copeia, 1961
primarily one of progressive simplification from an original complex of rather numerous independent bones (e.g., in Elops, Hollister, 1936:261, fig. 14). This progressive simplification has occurred independently in a large number of lineages both within and below the perciform level of structural organization.

A review of hybridization in marine angelfishes (Perciformes: Pomacanthidae)
Environmental Biology of Fishes, 1994Although hybridization of terrestrial and freshwater organisms has been well-studied, very little work has focused on hybridization among coral reef fish species. In the present paper, eleven examples of probable hybrids between marine angelfishes (Pomacanthidae) are reviewed.

Amphibious vision inCoryphoblennius galerita L. (Perciformes)
Experientia, 1992The morphology of the ophthalmic cornea in the blenniid fish Coryphoblennius galerita (Teleostei) shows adaptation to the amphibious life. Amphibious vision is provided by a flattened area within the cornea. Eyes of other, non-amphibious blenniids are compared with those of C. galerita.
