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'' ...

Percopsidae
Percopsidae is a family of fish in the order Percopsiformes, with one extant genus with two species, both endemic to North America, and two known fossil genera. They are small fish with weak fin spines, and an adipose fin similar to those of trout. They feed on insects and small crustaceans Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp.

Amblyopsidae
The Amblyopsidae are a fish family commonly referred to as cavefish, blindfish, or swampfish. They are small freshwater fish found in the dark environments of caves (underground lakes, pools, rivers and streams), springs and swamps in the eastern half of the United States. Like other troglobites, most amblyopsids exhibit adaptations to these dark environments, including the lack of functional eyes and the absence of pigmentation. More than 200 species of cavefishes are known,Riesch, R.; Tobler, M.; and Plath, M. (2015). ''Extremophile Fishes: Ecology, Evolution, and Physiology of Teleosts in Extreme Environments.'' but only six of these are in the family Amblyopsidae.Romero, A., editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. One of these, ''Forbesichthys agassizii'', spends time both underground and aboveground. A seventh species in this family, ''Chologaster cornuta'', is not a cave-dweller but lives in aboveground swamps. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Cavefish
The northern cavefish or northern blindfish (''Amblyopsis spelaea'') is found in caves through Kentucky and southern Indiana. It is listed as a threatened species in the United States and the IUCN lists the species as near threatened. During a 2013 study of ''Amblyopsis spelaea'', scientists found that the species was divided into two distinct evolutionary lineages: one north of the Ohio River, in Indiana, and one south of the river, in Kentucky. The southern population retained the name ''A. spelaea'' and the northern was re-designated '' Amblyopsis hoosieri'' in a 2014 paper published in the journal ''ZooKeys''. Neither species is found north of the White River, flowing east to west south of Bedford, Indiana Bedford is a city in Shawswick Township, Lawrence County, Indiana, Shawswick Township and the county seat of Lawrence County, Indiana, Lawrence County, Indiana, United States.

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 ...

Actinopterygii
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 Actinopt ...
