Empetrichthys is a genus of splitfins endemic to the state of Nevada in the United States. In 1989 they only had an estimated population of 24800, while its two other subspecies had gone extinct. This species mating season typically falls in spring. These animals are in danger and facing threats because their water is drying out because of pumping of ground water for agricultural developments.

Species

There are currently two recognized recent species in this genus of which only one is extant, in addition to one fossil species: [2]

Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm in size to the 3 m (9.8 ft) giant barb. 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 kyprînos.

<span class="mw-page-title-main">Aulopiformes</span> Order of fishes

Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "Aulopus-shaped", from Aulopus + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek aulós + Latin forma, the former in reference to the elongated shape of many aulopiforms.

Cheilodactylidae, commonly called morwongs but also known as butterfish, fingerfins, jackassfish, sea carp, snappers, and moki, is a family of marine ray-finned fish. They are found in subtropical oceans in the Southern Hemisphere. The common name "morwong" is also used as a name for several unrelated fish found in Australian waters, such as the painted sweetlips. The classification of the species within the Cheilodactylidae and the related Latridae is unclear.

<span class="mw-page-title-main">Goodeidae</span> Family of fishes

Goodeidae is a family of teleost fish endemic to Mexico and some areas of the United States. Many species are known as splitfins. This family contains about 50 species within 18 genera. The family is named after ichthyologist George Brown Goode (1851-1896).

<span class="mw-page-title-main">Murinae</span> Subfamily of rodents

The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.

<span class="mw-page-title-main">Anostraca</span> Order of crustaceans

Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes, and Antarctic ice. They are usually 6–25 mm (0.24–0.98 in) long. Most species have 20 body segments, bearing 11 pairs of leaf-like phyllopodia, and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces, with the exception of Branchinecta gigas, or "giant fairy shrimp", which is itself a predator of other species of anostracans. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families.

<span class="mw-page-title-main">Cirrina</span> Suborder of octopuses

Cirrina or Cirrata is a suborder and one of the two main divisions of octopuses. Cirrate octopuses have a small, internal shell and two fins on their head, while their sister suborder Incirrina has neither. The fins of cirrate octopods are associated with a unique cartilage-like shell in a shell sac. In cross-section, the fins have distinct proximal and distal regions, both of which are covered by a thin surface sheath of muscle.

The Raycraft Ranch killifish or Raycraft poolfish, a subspecies of the killifish Empetrichthys latos, was first described in 1948. This subspecies was restricted to a single spring on the Raycraft Ranch in the Pahrump Valley of Nye County, Nevada. It became extinct, most likely late in the 1950s, as a result of groundwater extraction and the filling in of the spring, along with competition from introduced carp species.

<span class="mw-page-title-main">Redfingers</span> Species of fish

The redfingers is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only off the coasts of Namibia and South Africa, in rock pools and from shallow depths to 120 m, on rocky reef areas. Its length is up to 30 cm.

<i>Caranx</i> Genus of fishes

Caranx is a genus of tropical to subtropical marine fishes in the jack family Carangidae, commonly known as jacks, trevallies and kingfishes. They are moderate- to large-sized, deep-bodied fishes which are distinguished from other carangid genera by specific gill raker, fin ray and dentition characteristics. The genus is represented in the Pacific, Indian and Atlantic Oceans, inhabiting both inshore and offshore regions, ranging from estuaries and bays to deep reefs and offshore islands. All species are powerful predators, taking a variety of fish, crustaceans and cephalopods, while they in turn are prey to larger pelagic fishes and sharks. A number of fish in the genus have a reputation as powerful gamefish and are highly sought by anglers. They often make up high amounts of the catch in various fisheries, but are generally considered poor to fair table fishes.

<span class="mw-page-title-main">Goodeinae</span> Subfamily of fishes

Goodeinae is a subfamily of splitfins from Mexico, part of the family Goodeidae. They are small fish which mostly live in fresh water, especially around Mesa Central, west of Mexico City. Members of the subfamily are also found in brackish water on both the east and west coasts. They typically have small ranges and many are seriously threatened. The subfamily takes its name from its type genus Goodea and so is ultimately named after the American ichthyologist George Brown Goode (1851-1896).

It is endemic to Nevada in the United States, where it was limited to the Pahrump Valley near the California border. It nearly became extinct due to habitat destruction and no longer occurs there. It is a federally listed endangered species of the United States. The Pahrump Poolfish is long-lived for a small-bodied fish, with ages up to 10 years for females and 7 years for males documented.

<i>Cheilodactylus</i> Genus of fishes

Cheilodactylus is a genus of marine ray-finned fishes belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family. They are found in the temperate waters of the southern hemisphere and in the North Pacific Ocean.

Arapaiminae is a subfamily of freshwater osteoglossiform (bony-tongued) fishes belonging to the family Osteoglossidae. It includes the South American arapaimas of the Amazon and Essequibo basins and the African arowana from the watersheds of the Sahelo-Sudanese region, Senegal, Gambia, and parts of Eastern Africa.
