Apricaphanius
''Apricaphanius'' is a genus of killifishes in the family Aphaniidae, which are native to northern Africa and southern Europe. All species in the genus have very small distributions and are seriously threatened. Etymology The generic name is derived from , "shining", referring to many small white spots on flanks of males, and ''Aphanius ''Aphanius'', commonly referred to as Mediterranean killifish, is a genus of the order Cyprinodontiformes in the family Aphaniidae.

Spanish Toothcarp
The Spanish toothcarp (''Apricaphanius iberus''), also known as the Spanish pupfish or Iberian killifish, is a small, endemic species of fish in the family Aphaniidae. Its risk of extinction is one of the greatest of any Iberian vertebrate. Its limited range, coupled with the drastic population decline the species has suffered in the last two decades, has caused it to be placed on endangered species lists, both in Spain and internationally. In addition, habitat fragmentation, likely due to humans, has resulted in this species becoming increasingly stagnant and has led to increased genetic drift. Also found to be contributing to their endangerment was genetic diversity of mitochondrial DNA. The mitochondrial DNA coupled with ''A. iberus''s geographic distribution has been able to affect their population genetic structure gradually in different spaces. Its conservation status in the south of the Iberian Peninsula has notably worsened. A similar fish in the peninsula's south-west ha ...

Apricaphanius Saourensis
''Apricaphanius saourensis'', the Sahara aphanius or Sahara killifish, is a species of freshwater pupfish belonging to the family Aphaniidae. It is endemic to the Oued Saoura river basin in Algeria. The species is threatened by water pollution and water withdrawal for agricultural use. It was last observed in the wild in 2003. Later surveys have not encountered the species, although a captive population exists; it was last evaluated by the IUCN 2021 and listed as critically endangered, possibly extinct in the wild. Etymology The species name, ''saourensis'', comes from "Saoura", the valley where the fish was collected. Description Like all members of the genus ''Apricaphanius'', the Sahara aphanius exhibits sexual dimorphism. Females possess brown mottling on their flanks and have transparent fins, whereas the much smaller males have bluish silver body mottling. Their fins have dark bars on them and are often blue in colour. Males grow to and females to in standard length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apricaphanius Baeticus
''Apricaphanius baeticus'' is a species of fish in the family Aphaniidae. It is endemic to a small part of Southern Spain, between the Gulf of Cadiz and Huelva. Its natural habitats are rivers, estuarine waters, and coastal saline lagoons. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ... and by invasive species.

Aphaniidae
Aphaniidae, the Oriental killifishes, are a family of the order Cyprinodontiformes. The 42 extant species of the family inhabit inland waters, rivers and lagoons. The distribution of these species extends from the entire Mediterranean region throughout the neighboring states of the Red Sea and Persian Gulf to southwest India. Several species in this family have very small distributions and are seriously threatened. Characteristics Aphaniidae are small fishes that usually grow to a length of . Their bodies are moderately elongated and only slightly flattened at the sides. The mouth is short and their teeth are tricuspid. Scales are complete, but can also be reduced or completely absent. All fins are rounded, dorsal and anal fins similar and are almost symmetrical, the pelvic fins can also be very small. There is usually sexual dimorphism and females are usually larger and have dots or spots on a solid colored background. The males often have horizontal stripes. There can also b ...

Aphanius
''Aphanius'', commonly referred to as Mediterranean killifish, is a genus of the order Cyprinodontiformes in the family Aphaniidae. They are found in fresh and brackish waters in the coastal plains of the Mediterranean region. Taxonomy and systematics There were formerly 39 recognized species in this genus. However, the family Aphaniidae was split in 2020, and species were reallocated to eight monophyletic genera. Several species were reallocated; to five resurrected genera ('' Anatolichthys'', '' Aphaniops'', '' Kosswigichthys'', '' Paraphanius'', and '' Tellia'') and two new genera '' Esmaeilius'' and '' Apricaphanius''. Species Following the split, there are two valid species: * '' Aphanius almiriensis'' Kottelat, Barbieri & Stoumboudi, 2007 * '' Aphanius fasciatus'' Valenciennes, 1821 (Mediterranean banded killifish) ;Fossil species *'' Aphanius crassicaudus'' Agassiz 1839 *''Aphanius yerevanicus'' Vasilyan et al. 2009 *''Lebias cephalotes'' Agassiz 1839 *''Lebias gaudr ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish, including families Aplocheilidae, Pantanodontidae, Cyprinodontidae, Fundulidae, Nothobranchiidae, Profundulidae, Aphaniidae and Valenciidae. All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killifish are small, measuring from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although killifish is sometimes used as an English eq ...

Cyprinodontidae
Pupfish are a group of small killifish belonging to ten genus, genera of the family Cyprinodontidae of ray-finned fish. Pupfish are especially noted for being found in extreme and isolated situations. They are primarily found in North America, South America, and the Caribbean region. As of August 2006, 120 nominal species and 9 subspecies were known. Several pupfish species are extinct and most extant species are listed. In the U.S., the most well-known pupfish species may be the Devils Hole pupfish, native to Devils Hole on the Nevada side of Death Valley National Park. Since 1995 the Devils Hole pupfish has been in a nearly steady decline, where it was close to extinction at 35–68 fish in 2013. The common name is said to derive from the mating habits of the males, whose activities vaguely resemble puppies at play; Carl Leavitt Hubbs, Carl L. Hubbs, a prominent ichthyology, ichthyologist and one of the first people to take an interest in them, coined the name after he observe ...

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
