Actinopterygii (/ ˌ æ k t ɪ n ɒ p t ə ˈ r ɪ dʒ i aɪ /; from Ancient Greek ἀκτίς (aktis) 'having rays' and πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish [2] that comprise over 50% of living vertebrate species. [3]
Acregoliath is an extinct genus of ray-finned fish that existed during the middle of Miocene epoch, about 13.76 to 13.34 million years ago. [1] It is known from very fragmentary remains which consist of several scales that were found in Brazil.
Acanthopterygii (meaning "spiny-finned one") is a superorder of bony fishes in the class Actinopterygii.Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.
Redfieldiiformes is an extinct order of ray-finned fish (actinopterygians) which lived from the Early Triassic to Early Jurassic. Redfieldiiforms were fairly typical Triassic fish in overall anatomy. They had a fusiform (streamlined, tuna-like) body shape with thick, ganoine-covered scales.
The big-scale pomfret (Taractichthys longipinnis) also known as the long-finned bream, is a species of marine ray-finned fish, a pomfret of the family Bramidae. It is found in the Atlantic ocean, at depths down to 500 metres (1,600 ft). This species is widely distributed in the Pacific, from temperate zones throughout the tropics.
Ophidiiform fish typically have slender bodies with small heads, and either smooth scales, or none at all. They have long dorsal fins, and an anal fin that is typically united with the caudal fin. The group includes pelagic, benthic, and even parasitic species, although all have a similar body form.
Fish portal; Actinopteri (/ æ k t ɪ ˈ n ɒ p t ə r aɪ /) is the sister group of Cladistia in the class Actinopterygii (ray-finned fish).. Dating back to the Permian period, the Actinopteri comprise the Chondrostei (sturgeons and paddlefish), the Holostei (bowfins and gars), and the teleosts; in other words, all extant ray-finned fish other than the bichirs.
The Priacanthidae, the bigeyes, are a family of 18 species of marine ray-finned fishes."Catalufa" is an alternate common name for some members of the Priacanthidae.The etymology of the scientific name (prioo-, to bite + akantha, thorn) refers to the family's very rough, spined scales.
