Type I interferons in ray-finned fish (Actinopterygii)

Fish & Shellfish Immunology, 2021
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.

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.

Tapeta lucida in bony fishes (Actinopterygii): a survey

Canadian 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.

Bioecology of Electric Fish (Actinopterygii: Gymnotiformes)

Middle East Research Journal of Biological Sciences
The poraquê has an elongated and cylindrical body, with just one anal fin, which extends across almost the entire abdomen it resembles the shape of an eel. Its head is flat and its mouth is equipped with a row of sharp, conical teeth. The color of this animal is always very dark, but the ventral part of the body is yellowish and they have poor vision ...

The Genus Polypterus (Bichirs): A Fish Group Diverged at the Stem of Ray-Finned Fishes (Actinopterygii)

Cold Spring Harbor Protocols, 2009
INTRODUCTIONAxis and germ-layer formations are central issues in vertebrate embryology that can be examined in the zebrafish, Xenopus, chick, and mouse. An intriguing question is how the mechanisms that existed in an ancestral vertebrate have been modified during vertebrate evolution.
