Pteronotropis Merlini
The orangetail shiner (''Pteronotropis merlini'') is a species of cyprinid fish endemic to the southeastern United States. It is endemic to in the Choctawhatchee River drainage in southeastern Alabama. Description The fish is similar to the sailfin shiner. It has a very deep and compressed body. It has between 35 and 42 scales along the lateral line. It has a maximum total length of 6.5 cm (2.5 in). It usually has 10 anal rays. Breeding males have a chevron-shaped black blotch at the origin of the caudal fin separated from a dark black stripe along the side, and have orange caudal and anal fins.

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Choctawhatchee River
The Choctawhatchee River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. The National Map , accessed 15 April 2011 river in the southern United States, flowing through southeast Alabama and the Panhandle of Florida before emptying into Choctawhatchee Bay in Okaloosa and Walton counties. The river, the bay and their adjacent watersheds collectively drain . Overview The Choctawhatchee originates as two separate forks (East Fork and West Fork) in Barbour County, Alabama; the East Fork flows through Henry County and joins the West Fork in eastern Dale County about four miles (6 km) above Newton. The unified river then flows southwest through Dale and Geneva counties into Florida, collecting tributaries along the way: the Little Choctawhatchee River in Dale County, and the Pea River near Geneva. It then flows south into Florida, terminating at Choctawhatchee Bay. Other Alabama tributaries are Claybank Creek and Tight Eye Creek. On ...

Sailfin Shiner
The sailfin shiner (''Pteronotropis hypselopterus'') is a species of cyprinid fish endemic to the southeastern United States. Description The sailfin shiner has a deep and compressed body, with a narrow base for the caudal fin. Its lateral line is curved downward. It has a maximum total length of 7 cm (2.75 in). The fish is pink-brown or olive on the top half and a white or light pink on the bottom half. It has a dark brown stripe that extends from the head to the dorsal fin, and has a steel-blue stripe along the side that has a thin pink to red line bordering above. The base of the caudal fin has a small red spot on the top and bottom of the side, while a black spot is on the center of the side of the base of the caudal fin. The dorsal fin has a dusky central band, and other fins are a yellow to light orange. The dorsal and anal fins are almost triangular, resembling sails, from which their common name is derived. Breeding males have light orange edges on their dorsal fins. ...

Fish Of The United States
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 ...
