Isozymes of glucosephosphate isomerase (PGI) in fishes of the subclass actinopterygii
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1986A compilation of the species of fishes of the subclass Actinopterygii for the study of the PGI isozyme system is given. PGI appears to be codified by more than one locus in fishes; 65% of the species analysed here have two loci for PGI. PGI duplication in fishes and the relationship of isozymes of PGI with temperature and metabolism are discussed.

Epimorphic regeneration of fins was studied in different ray-finned fishes (Actinopterygii), but species representing the phylogenetically basal lineages of the taxon have remained outside the attention of researchers. Information on the regenerative abilities of these groups is important both for understanding the evolutionary origins of the ...

Morphology, taxonomy, and phylogeny of Triassic pholidophorid fishes (Actinopterygii, Teleostei)
Journal of Vertebrate Paleontology, 2013ABSTRACT This study presents the first comprehensive revision of ‘pholidophoriform’ fishes, which are a key taxon for understanding the early diversification of teleost fish. Systematic revisions of Triassic pholidophorids, which are based on numerous well-preserved specimens, include †Annaichthys, gen. et sp. nov., †Knerichthys, gen.

An offshore fish assemblage (Elasmobranchii, Actinopterygii) from the Late Jurassic of NE Spain
Paläontologische Zeitschrift, 2012Bulk sampling of late Oxfordian and early Kimmeridgian sediments of the Sot de Chera Formation near the Village of Moneva in the Aragonese Branch of the Iberian Ranges (NE Spain) yielded a low-diversity fauna of sharks (Synechodus ungeri, Phorcynis sp. cf. P.

Bioecology of African Catfish and Poisonous Marine Fish (Actinopterygii: Teleostei)
Middle East Research Journal of Biological SciencesClarias gariepinus (Burchell, 1822) (Siluriformes: Clariidae) the African catfish is a large, eel-like fish, usually dark gray or black on the back and white on the ventral part, a smoother flat bony head compared to other catfish, and a wide, terminal mouth with four pairs of barbels.

Comparative ultrastructure of Langerhans‐like cells in spleens of ray‐finned fishes (Actinopterygii)
Journal of Morphology, 2010AbstractWe studied the morphology and occurrence of splenic Langerhans‐like (LL) cells in species representing 11 orders of ray‐finned fishes, Actinopterygii. LL cells were frequent in spleen tissue of species among Cypriniformes, Esociformes, Salmoniformes, and Pleuronectiformes. These cells contained granules which resembled Birbeck granules known to

Ginglymodian fishes formed one of the most dominant actinopterygian lineages during the Mesozoic, occurring in fully marine to freshwater depositional environments. However, although commonly preserved in Mesozoic strata around the world, there is little
