Morphology, taxonomy, and phylogeny of Triassic pholidophorid fishes (Actinopterygii, Teleostei)

Journal of Vertebrate Paleontology, 2013
ABSTRACT 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.

Fishes (Elasmobranchii and Actinopterygii) of Picãozinho reef, Northeastern Brazil, with notes on their conservation status

Zootaxa, 2007
Shallow reefs on the northeastern coast of Brazil are rich, productive and diverse environments, with great ecological and economical importance. Picãozinho is located 1,500 m off the coast of João Pessoa city, Paraíba state, NE Brazil. The aim of this work is to provide an updated list of the reef fishes of Picãozinho, based on a survey of ...

Comparative Analysis of the Organization of the Catecholaminergic Systems in the Brain of Holostean Fishes (Actinopterygii/Neopterygii)

Brain, Behavior and Evolution, 2019
Living holosteans, comprising 8 species of bowfins and gars, form a small monophyletic group of actinopterygian fishes, which are currently considered as the sister group to the enormously numerous teleosts and have largely been neglected in neuroanatomical studies.

Comparative ultrastructure of Langerhans‐like cells in spleens of ray‐finned fishes (Actinopterygii)

Journal of Morphology, 2010
AbstractWe 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

Isozymes of soluble malate dehydrogenase (s-MDH) in fishes of the subclasses chondrichthyes and actinopterygii

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990
Abstract 1. 1. A recopilation of species of fishes used for the study of s-MDH isozymes was made. 2. 2. s-MDH of most fishes was shown to be codified by two gene loci. However, there are fishes with a more complex pattern, with s-MDH composed of subunits codified in three or four gene loci. 3. 3.
