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.
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 ray-finned fishes contain most of the species of fish and these are divided into 46 orders. Most of the fishes known to aquarists and anglers are within this class. **Subcategories are listed below for all 46 orders and examples of common fish in each order can be found at Actinopterygii

The fish uses these pectoral fins to clamber along the sea bottom. The number of pectoral fin rays is reduced (6-7 as opposed to 8 or more in other frogfish), and the Butler's frogfish can move each ray individually like "fingers" to steady itself or to hold on to objects. The pelvic fins contain 5 rays each and are placed beneath the body. The ...

Its name originates from the Old French word "dars" which is the nominative form of the word "dart" in reference to their swimming pattern. The western blacknose dace (Rhinichthys obtusus) formerly was considered conspecific.
