Stylephoriformes
''Stylephorus chordatus'', the tube-eye or thread-tail, is a deep-sea fish, the only fish in the genus ''Stylephorus'' and family Stylephoridae. It is found in deep subtropical and tropical waters around the world, living at depths during the day and making nightly vertical migrations to feed on plankton. It is an extremely elongated fish; although its body grows only to long, its pair of tail fin rays triple its length to about . Its eyes are tubular in shape, resembling a pair of binoculars. It has a tubular mouth through which it sucks seawater by enlarging its oral cavity to about 40 times its original size. It then expels the water through the gills, leaving behind the copepods on which it feeds. The phylogenetic position of the tube-eye has been controversial. It has been historically placed amongst Lampriformes, but a study involving mitochondrial and nuclear DNA sequences analysis suggested ''Stylephorus'' is instead a close parent of the Gadiformes Gadiformes are ...

Percopsiformes
The Percopsiformes are a small order of ray-finned fishes, comprising the trout-perch and its allies. It contains just ten extant species, grouped into seven genera and three families. Five of these genera are monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispe ... They are generally small fish, ranging from in adult body length. They inhabit freshwater habitats in North America. They are grouped together because of technical characteristics of their internal anatomy, and the different species may appear quite different externally. * Order Percopsiformes Berg 1937 ** Genus †'' Lateopisciculus'' Murray & Wilson1996 ** Genus †'' Percopsiformorum'' tolith** Suborder Percopsoidei Berg 1937 *** Family † Libotoniidae Wilson & Williams 1992 **** Genus †'' Libotonius'' ...

Zeiformes
The Zeiformes are a small order of marine ray-finned fishes most notable for the dories, a group of common food fish. The order consists of about 33 species in seven families, mostly deep-sea types. Zeiform bodies are usually thin and deep. Mouths are large, with distensible jaws, and there is no orbitosphenoid. Pelvic fins have 5–10 soft rays and possibly a spine, 5–10 dorsal fin spines and up to 4 anal fin spines. They range in size from the dwarf dory ''(Macrurocyttus acanthopodus)'', at in length, to the Cape dory ''(Zeus capensis)'', which measures up to . The boarfishes (Caproidae) have been included in this order though they are currently included in the Perciformes.

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 .

Superorder
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Trout-perch
''Percopsis omiscomaycus'', also known as the trout-perch, the grounder or the sand minnow, is one of two species in the family Percopsidae. Its name comes from the Greek root words ''perc'', meaning perch and ''opsi'' meaning appearance. The species name ''omiscomaycus'' is thought to be derived from a Native American word meaning ''trout''. These are freshwater fish that prefer clear to slightly turbid water, and are found in rivers and lakes throughout North America.Bosanko, Dave (2007), "Fish of Minnesota – Field Guide", pp. 162–163, Adventure Publication, Cambridge, MN. They are a generally small fish found in deep waters by day, but which migrate to shallower waters at night.They are most often seen washed up on beaches and are rarely seen alive or correctly identified. The trout-perch possess characteristics similar to both the trout and the perch.Bramblett, Robert, "Montana Cooperative Fishery Research Unit", Department of Ecology, Montana State University-Boz ...
