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 (0.5 in) 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.
In botany, apomixis is asexual development of seed or embryo without fertilization. However, other definitions include replacement of the seed by a plantlet or replacement of the flower by bulbils.
Paedocypris is a genus of tiny cyprinid fish found in swamps and streams on the Southeast Asian islands of Borneo, Sumatra and Bintan.
The Iberian ribbed newt, gallipato or Spanish ribbed newt is a newt endemic to the central and southern Iberian Peninsula and Morocco. It is the largest European newt species and it is also known for its sharp ribs which can puncture through its sides, and as such is also called the sharp-ribbed newt.
Parthenogenesis is a natural form of asexual reproduction in which the embryo develops directly from an egg without need for fertilization. In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg.
Anaecypris hispanica, the Spanish minnowcarp, is a small species of ray-finned fish species in the family Cyprinidae. It is endemic to the Iberian Peninsula and is found in the basin of the Guadiana River in southern Spain and Portugal. Its natural habitats are rivers and intermittent rivers which are shallow, highly oxygenated, have a water temperature of no more than 25 °C (77 °F) and have a coarse stream bed. It is threatened by habitat loss. They grow to a maximum size of 60 mm (2.4 in) and live for three years.
The Northern straight-mouth nase is a species of ray-finned fish in the family Cyprinidae. It is found in Portugal and Spain. Its natural habitat is rivers. It is threatened by habitat loss.
The Iberian nase is a species of freshwater fish in the family Cyprinidae. It is found in Portugal and in Spain. Its natural habitats are rivers and intermittent rivers.
Pseudochondrostoma willkommii is a species of cyprinid fish, which is found in Portugal and Spain. Its natural habitats are rivers and water storage areas, and it is threatened by habitat loss.
Ladigesocypris ghigii, the Rhodes minnow, is a species of freshwater fish in the family Cyprinidae, also known as the gizani or ghizáni. It is currently considered to be endemic to the island of Rhodes, Greece. Its natural habitats are rivers, intermittent rivers, freshwater marshes, freshwater springs, and water storage areas. It is threatened by habitat loss.
Squalius is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. S. alburnoides is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to Anaecypris; the latter mated with ancestral S. pyrenaicus. Present-day S. alburnoides mates with sympatric congeners of other species.
Squalius carolitertii, the Northern Iberian chub, is a species of fresh-water fish in the family Cyprinidae. It is found in Portugal and Spain, and known there as the bordallo, escalo or gallego.
Squalius keadicus is a species of fresh-water fish in the family Cyprinidae. It is found only in Greece, and known as the menida in Greek.
Squalius svallize is a species of freshwater fish in the family Cyprinidae. It is found in Bosnia and Herzegovina and Croatia. Its natural habitats are rivers and inland karsts. It is threatened by habitat loss.
Achondrostoma arcasii, termed the bermejuela, is a species of freshwater fish in the family Cyprinidae. It is found in the Douro River in northern Portugal and in rivers draining to both the Atlantic Ocean and the Mediterranean, including the Ebro River, in northern Spain where it is threatened by loss of habitat caused by the building of canals and the construction of dams, as well as by introduced predators and water pollution.
Squalius janae, commonly known as the Istrian chub, is a species of freshwater fish in the carp family Cyprinidae. It was first described in 2010 from the Dragonja River drainage in Slovenia. Since then they have also been found in the Boljunčica and Pazinčica river drainages in Istria, Croatia.
Squalius valentinus, commonly known as the Valencia chub and the Levantine bagra, is a species of freshwater fish in the carp family Cyprinidae. It was first isolated from the Turia River in Valencia, hence its name. It is considered endangered. This species is differentiated from its cogenerates by having eight branched rays in its dorsal fin; eight branched rays in its anal fin; two rows of pharyngeal teeth on both sides possessing 2 and 5 teeth ; a wide caudal peduncle; its number of gill rakers; the number of scales in its lateral line; the number of scale rows above the latter; by possessing three scale rows below it; by having thirty-nine vertebrae ; showing large 4th and 5th infraorbital bones; a maxilla with a very distinct marked anterior process; exhibiting a frontal bone expanded at the middle; a wide neurocranium bone; the lower branch of the pharyngeal bone being robust; a large and narrow urohyal; as well as genetic differences (allozymes).
Squalius malacitanus, commonly known as the Málaga chub, is a species of freshwater fish in the carp family Cyprinidae. It was first isolated from the Guadalmina River in Málaga, hence its name. It is considered a vulnerable species. S. malacitanus differs from its cogenerate species by having 7–8 branched rays in its dorsal fin, 8 branched rays in the anal lateral line; the number of scale rows above its lateral line; possessing 3 scale rows below its lateral line; 38 vertebrae, 21 abdominal, and 17 caudal; large fourth and fifth infraorbital bones; maxilla without a pointed anterior process; the middle of its frontal bone being narrow, as well as its neurocranium bone; the lower branch of its pharyngeal bone is rather long; and the shortness of the inferior lamina of its urohyal bone.
Capoeta razii, is a newly described species of freshwater cyprinid fish occurring mainly in the southern Caspian Sea basin, Iran. This species was mistakenly reported by many authors as Capoeta gracilis in northern Iranian regions. It was first reported to be different from C. gracilis by Levin et al. (2012).
Androgenesis is a system of asexual reproduction that requires the presence of eggs and occurs when a zygote is produced with only paternal nuclear genes. During standard sexual reproduction, one female parent and one male parent each produce haploid gametes, which recombine to create offspring with genetic material from both parents. However, in androgenesis, there is no recombination of maternal and paternal chromosomes, and only the paternal chromosomes are passed down to the offspring.. The offspring produced in androgenesis will still have maternally inherited mitochondria, as is the case with most sexually reproducing species.
