- proper n. A taxonomic class within the superclass Osteichthyes — the ray-finned fish.
These include ray-finned fish subclass Actinopterygii, "new-finned" fish Neopterygii, Messel garfish Atractosteus strausi, Messel bowfin Cyclurus ( 'Amia') kehreri, Archaic knife-fish Thaumaturus intermedius, Messel eel Anguilla ignota, high-backed predatory Messel perch Amphiperca multiformes, and double-finned Messel perch Palaeoperca proxima.
Actinopterygii consists of the the ray-finned fish, which makes up most of the species of
By integrating phylogenetics of novel vtg transcripts from old and modern teleosts with syntenic analyses of all available genomic variants of non-metatherian vertebrates we identify the gene orthologies between the Sarcopterygii (tetrapod branch) and Actinopterygii (fish branch).
The vertebrate vtg gene cluster existed prior to the separation of Sarcopterygii from Actinopterygii >
And a cabinet-level Secretary of the Actinopterygii.
Actinopterygii consists of the the ray-finned fish, which makes up most of the species of Osteichthyes (about 27,000 species).
We here report on a comparative investigation of the genetic variation, base composition, presence of indels, and selection in Rag1 in different vertebrate lineages (Actinopterygii, Amphibia,
