Gadiformes
Gadiformes are an order of ray-finned fish, also called the Anacanthini, that includes the cod. Many major food fish are in this order. They are found in marine waters throughout the world and the vast majority of the species are found in temperate or colder regions (tropical species are typically deep-water). A few species may enter estuaries but only one, the burbot (''Lota lota''), is a freshwater fish. Common characteristics include the positioning of the pelvic fins (if present), below or in front of the pectoral fins. Gadiformes are physoclists, which means their swim bladders do not have a pneumatic duct. The fins are spineless. Gadiform fish range in size from the codlets, which may be as small as in adult length, to the Atlantic cod, ''Gadus morhua'', which reaches up to .

Merlucciidae
The Merlucciidae, commonly called merluccid hakes , are a family of cod-like fish, including most hakes. available for download at http://www.fao.org They are native to cold water in the Atlantic and Pacific Oceans, and typically are found at depths greater than in subtropical, temperate, sub-Arctic or sub-Antarctic regions. The best known species are in the genera ''Macruronus'' and ''Merluccius''. These predatory fish are up to in length, though most only reach about half that length, inhabiting the waters of the continental shelf and upper continental slope, where they feed on small fish such as lanternfishes. Several species are important commercial fish, for example the blue grenadier (''Macruronus novaezelandiae'') that is fished in the southwest Pacific and the North Pacific hake (''Merluccius productus'') that is fished off western North America. The taxonomy of the Merluccidae is not settled, with some authorities raising two or three subfamilies, the Merluccinae, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrouridae
Macrouridae is a family of deep sea fish, a diverse and ecologically important group, which are part of the order of cod-like fish, the Gadiformes. The species in the Macrouridae are characterised by their large heads which normally have a single barbel on the chin, projecting snouts, and slender bodies that taper to whip-like tails, without an obvious caudal fin but what there is of the caudal fin is often confluent with the posterior dorsal and anal fins. There are normally two dorsal fins, the anterior dorsal fin is quite high, the posterior quite low but is longer and takes up a greater proportion of the fish's of the back, species in the subfamily Macrouroidinae have a single dorsal fin. The long anal fin is almost as long as the second dorsal fin is nearly as long as the posterior dorsal, and sometimes it is longer. The pelvic fin is inserted in the vicinity of the thorax and normally has 5-17 fin rays but are absent in '' Macrouroides''. The body is covered in small scal ...

Fossil record Fossils of ''Bregmaceros'' are found from the Eocene to the Quaternary (age range: from 37.2 to 0.0 million years ago.). They are known from various localities in Europe, North America and South America.

Gadidae
The Gadidae are a family of marine fish, included in the order Gadiformes, known as the cods, codfishes, or true cods. It contains several commercially important fishes, including the cod, haddock, whiting, and pollock. Most gadid species are found in temperate waters of the Northern Hemisphere, but several range into subtropical, subarctic, and Arctic oceans, and a single ( southern blue whiting) is found in the Southern Hemisphere. They are generally medium-sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans. Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy. Concepts differ about the contents of the family Gadidae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...
