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 ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Alburnus Doriae
''Alburnus doriae'' is a species of cyprinid fish from Iran. It was previously thought to be restricted to central Iran, but recent research shows that it is more widespread and that ''Alburnus amirkabiri'' and ''Petroleuciscus esfahani'' are probably a synonyms of ''Alburnus doriae''. Description ''Alburnus doriae'' is a fish with a slender body which shows marked lateral compression with as lightly convex or straight dorsal profile. It has a pointed snout and the lower jaw normally projects beyond the upper jaw, the snout being at least as long as the diameter of the eye and equal to the interorbital distance, the interorbital area is concave. The mouth points upwards. The maximum standard length is 134mm. The back is dark olive-brown through to grey in colour with silver on the flanks, belly and lower part of the head, a dark grey strip runs from the back of the eye to the caudal peduncle with darker brown spots below and above the lateral line. The fins lack colour apart fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Petroleuciscus'' is a genus of four species of ray-finned fish in the family Cyprinidae. It was usually included in ''Leuciscus'' until recently. This genus unites the Ponto-Caspian chubs and daces. Recent research has indicated that ''Petroleuciscus esfahani'' is probably a synonym of ''Alburnus doriae''.

Fish Described In 2010
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. Mos ...
