Percina Stictogaster
The frecklebelly darter (''Percina stictogaster'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the Family (biology), family Percidae, which also contains the perches, Gymnocephalus, ruffes and Sander (fish), pikeperches. It primarily occurs in the upper Kentucky and Green river systems of eastern and central Kentucky and north-central Tennessee, being found mostly in the Cumberland Plateau and Highland Rim regions.Warren Jr, Melvin L., et al. "Diversity, distribution, and conservation status of the native freshwater fishes of the southern United States." Fisheries 25.10 (2000): 7-31. The fish gets its name from gets its name from the scattered dark spots on its relatively pale underside. However, a possible more telling characteristic of the species is the systematical arrangement of the spots at the base of the tail as well as the continuous stripes down either side of the back. Total population size is unknown but figured to be ... [...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 Actinoptery ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Etheostomatinae
Etheosomatidae is a species rich subfamily of freshwater ray-finned fish, the members of which are commonly known as the darters. The subfamily is part of the family Percidae which also includes the perches, ruffes and pikeperches. The family is endemic to North America. It consists of 3-5 different genera and well over 200 species. Characteristics Species within the Etheostomatinae are all small fish, mostly less than in length and their bodies are slightly compressed or fusiform in shape. They have two pterygiophores between the first and second dorsal fins which do not have spines and a reduced swimbladder which may be completely lacking. The name darter becomes because these fish are seen to dart around in their habitat and these fish have benthic habits. They are sexually dimorphic and most species have males with bright colours and patterning, particularly when breeding and these colours and patterns are used to attract females and allow for recognition of species ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more than 200 species in 11 genera. The perches, and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Characteristics The family is characterised by having the dorsal fin split into two which are normally separated or have a narrow connection, although this is wider in the genus ''Zingel'', the front section contains the spines and the rear section contains the soft rays. The anal fin contains 1 or 2 spines, if there is a second spine it is typically weak. The pelvic fins are placed on the thorax and have a single spine and 5 soft rays. They also have skeletal synapomorphies. The maximum size attained in in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perch
Perch is a common name for fish of the genus ''Perca'', freshwater gamefish belonging to the family Percidae. The perch, of which three species occur in different geographical areas, lend their name to a large order of vertebrates: the Perciformes, from the el, πέρκη (), simply meaning perch, and the Latin ''forma'' meaning shape. Many species of freshwater gamefish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater-dwelling red drum is often referred to as a red perch, though by definition perch are freshwater fish. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. The type species for this genus is the European perch, ''P. fluviatilis''. Species Most authorities recognize three species within the perch genus: * The European perch (''P. fluviatilis'') is primarily found in Europe, but a few can also be found in South Africa, and even as far ea ...

Gymnocephalus
''Gymnocephalus'' is a genus of ray-finned fishes from the family Percidae, which includes the perches, pike-perches and darters. They are from the Western Palearctic area, although one species, ''Gymnocephalus cernua'' has been accidentally introduced to the Great Lakes region where it is regarded as an invasive species. They have the common name "ruffe" and resemble the true perches in the genus ''Perca'', but are usually smaller and have a different pattern. Characteristics The species within the genus ''Gymnocephalus'' have a number of characters in common including that their dorsal fins are not completely separate, they have enlarged canals extending from the lateral line on their heads, the preorbital bone covers the maxillary bone, presence of setiform or bristle-like teeth, having very few or no vomerine and palatine teeth and the possession of three paired bones in the neck, known as extrascapulars, in their lateral line system, of which, two are simple tubes.

Sander (fish)
''Sander'' (formerly known as ''Stizostedion'') is a genus of predatory ray-finned fish in the family Percidae, which also includes the perches, ruffes, and darters. They are also known as "pike-perch" because of their resemblance to fish in the unrelated Esocidae (pike) family. They are the only genus in the monotypic tribe Luciopercini, which is one of two tribes in the subfamily Luciopercinae, Characteristics ''Sander'' species have elongated and laterally compressed bodies and they range in total length from in the Volga pikeperch (''S. volgensis'') to in the zander (''S. lucioperca''). The species within the genus share canine-like teeth that are at their largest in the zander, and although they are not present in adult Volga pikeperches, they do possess them as juveniles. in addition, they have thin rows of teeth on their jaws, vomer, and palatines, the preopercle shows strong serrations along its edges, a continuous lateral line reaches all the way from the head to the ...

Percina
''Percina'' is a genus of small freshwater ray-finned fish, classified within the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches from North America. Like the similar fishes in the genus ''Etheostoma'', they are some species called "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of ''Percina'' with a pattern of vertical bars on the flanks are called logperches. Species There are currently 49 recognized species in this genus: * '' Percina antesella'' J. D. Williams & Etnier, 1978 (Amber darter) * ''Percina apristis'' C. L. Hubbs & Hubbs, 1954 (Guadalupe darter) * '' Percina aurantiaca'' Cope, 1868 (Tangerine darter) * '' Percina aurolineata'' Suttkus & Ramsey, 1967 (Goldline darter) * '' Percina aurora'' Suttkus & B.

Fish Described In 1993
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. Most fis ...
