Type I interferons in ray-finned fish (Actinopterygii).

Fish & Shellfish Immunology, 2020
Interferons (IFNs) are proteins of vital importance in the body's immune response. They are formed in different types of cells and have been found in fish, amphibians, reptiles and mammals. Two types of IFN have been found in ray-finned fish (Superclass: Osteichthyes, Class: Actinopterygii) so far, i.e.

FIRST RECORD OF A PACHYCORMID FISH (ACTINOPTERYGII: PACHYCORMIFORMES) FROM THE LOWER CRETACEOUS OF AUSTRALIA

Journal of Vertebrate Paleontology, 2007
The Pachycormidae (Pachycormiformes) are an extinct group of Mesozoic marine fishes tentatively identified as stem-teleosts in recent phylogenetic analyses (see Arratia 2004 for summary).

Tapeta lucida in bony fishes (Actinopterygii): a survey [PDF]

open access: possibleCanadian Journal of Zoology, 1973
Bony fishes belonging to 75 families were examined for ocular tapeta lucida. The results are collated with published records, and tapeta are shown to occur in 28 families of teleostomes (Holostei and Teleostei) listed in Table 2. Except in the bigeyes Priacanthidae, they are diffuse reflectors located in the pigment epithelium.

Retroposons of salmonoid fishes (Actinopterygii: Salmonoidei) and their evolution

Gene, 2009
Short and long retroposons, or non-LTR retrotransposons (SINEs and LINEs, respectively) are two groups of interspersed repetitive elements amplifying in the genome via RNA and cDNA-mediated reverse transcription. In this process, SINEs entirely depend on the enzymatic machinery of autonomous LINEs.

‘Fish’ (Actinopterygii and Elasmobranchii) diversification patterns through deep time

Biological Reviews of The Cambridge Philosophical Society, 2016
Actinopterygii (ray‐finned fishes) and Elasmobranchii (sharks, skates and rays) represent more than half of today's vertebrate taxic diversity (approximately 33000 species) and form the largest component of vertebrate diversity in extant aquatic ...

Characteristics of the reparative regeneration of fins in the polypterid fish (Polypteridae, Actinopterygii)

Russian Journal of Developmental Biology, 2012
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 ...

Palaeobiogeography of Cretaceous bony fishes (Actinistia, Dipnoi and Actinopterygii) [PDF]

open access: possibleGeological Society, London, Special Publications, 2008
Abstract Dispersal and vicariant patterns have been used as opposite concepts to explain biogeographical histories of organisms. Vicariance has been preferred to dispersal: the former is said to be falsifiable while the latter is regarded as a contingent hypothesis.
