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.
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.
Acipenseriformes / æ s ɪ ˈ p ɛ n s ə r ɪ f ɔːr m iː z / is an order of basal [1] ray-finned fishes that includes living and fossil sturgeons and paddlefishes (Acipenseroidei), as well as the extinct families Chondrosteidae and Peipiaosteidae. [2] [3] [4] They are the second earliest diverging group of living ray-finned fish after the ...
Clupeiformes / ˈ k l uː p iː ɪ f ɔːr m iː z / is the order of ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important forage and food fish. Clupeiformes are physostomes, which means that their gas bladder has a pneumatic duct connecting it to the gut.
The false scorpionfish (Centrogenys vaigiensis), also known as prettyfins, is a species of ray-finned fish, the only species in genus Centrogenys, which in turn is the only genus in the family Centrogenyidae. [4] They are pale grey or brown and usually grow no longer than 25 cm (9.8 in).
Ctenoid scales cover most of the body apart from the snout. [3] The dorsal fin is continuous, [4] and has its origin quite far to the rear of the head and longer than the anal fin. [3] The dorsal fin contains 11 spines and 11–12 soft rays while the anal fin has 3 spines and 11 soft rays. [2] The caudal fin is emarginate but not deeply so. [3]
These individual fin rays can be curved nearly twice the maximum recorded curvature for ray-finned fish fin rays during locomotion. These fin rays are curved into the direction of motion, indicating that the knifefish has active control of the fin ray curvature, and that this curvature is not the result of passive bending due to fluid loading.

Teleostei (/ ˌ t ɛ l i ˈ ɒ s t i aɪ /; Greek teleios "complete" + osteon "bone"), members of which are known as teleosts (/ ˈ t ɛ l i ɒ s t s, ˈ t iː l i-/), [4] is, by far, the largest infraclass in the class Actinopterygii, the ray-finned fishes, [a] and contains 96% of all extant species of fish. Teleosts are arranged into about 40 ...
