Developmental changes of opsin gene expression in ray-finned fishes (Actinopterygii)
Proceedings of the Royal Society B: Biological Sciences, 2022 AbstractFish often change their habitat and trophic preferences during development. Dramatic functional differences between embryos, larvae, juveniles and adults also concern sensory systems, including vision. Here we focus on the photoreceptors (rod and cone cells) in the retina and their gene expression profiles during the development.

Acta Ichthyologica et Piscatoria, 2020 An individual of Pigfish, Orthopristis chrysoptera (Linnaeus, 1766), is recorded for the first time for the Mediterranean Sea, raising to six the number of species of the family Haemulidae in the basin. The fish was caught on 12 September 2020 in the harbor of Siracusa (Ionian Sea) by an angler and had an estimated total length of about 16 cm. Possible

Biological aspects of an interesting fossil fish: Paramblypterus duvernoyi (Amblypteridae, Actinopterygii) [PDF]
Mitteilungen aus dem Museum für Naturkunde in Berlin. Geowissenschaftliche Reihe, 2008 Based on three-dimensional models of the skull and body of Paramblypterus duvernoyi, function of the feeding apparatus and potential of locomotion are interpreted. Compared to most other lower actinopterygians, certain modified features regarding the suspensory apparatus, snout bones, gape, dermohyal and suborbital region, and palaloquadrate-maxillary ...

Is Nematocharax (Actinopterygii, Characiformes) a monotypic fish genus? [PDF]
Genome, 2016 The combination of DNA barcodes and geometric morphometrics is useful to discriminate taxonomically controversial species, providing more precise estimates of biodiversity. Therefore, our goal was to assess the genetic and morphometric diversity in Nematocharax, a controversial monotypic and sexually dimorphic genus of Neotropical fish, based on ...

Bony labyrinth morphology in early neopterygian fishes (Actinopterygii: Neopterygii) [PDF]
Journal of Morphology, 2016 ABSTRACTEndocasts of the osseous labyrinth have the potential to yield information about both phylogenetic relationships and ecology. Although bony labyrinth morphology is well documented in many groups of fossil vertebrates, little is known for early Neopterygii, the major fish radiation containing living teleosts, gars and the bowfin.

Phylogenetic analyses of ray-finned fishes (Actinopterygii) using collagen type I protein sequences [PDF]
Royal Society Open Science, 2021 Ray-finned fishes (Actinopterygii) are the largest and most diverse group of vertebrates, comprising over half of all living vertebrate species. Phylogenetic relationships between ray-finned fishes have historically pivoted on the study of morphology, which has notoriously failed to resolve higher order relationships, such as within the percomorphs ...
