Sedercypris
''Sedercypris'', commonly known as Cedarberg redfins, is a genus of fish in the family Cyprinidae endemic to the Clanwilliam Olifants River system in South Africa. The following species are classified in this genus: * '' Sedercypris calidus'' (Barnard, 1938) (Clanwilliam redfin) * '' Sedercypris erubescens'' ( Skelton, 1974) (Twee River redfin) Both species are tetraploid, like ''Pseudobarbus'' redfins, from which they were separated in 2018. The distinction from all other southern African tetraploid genera is having six or seven branched rays in the anal fin. Etymology ''Sedercypris'' is named after the Cedarberg region they inhabit. The Afrikaans spelling was adopted for the name to avoid the possible confusion with the genus ''Cheilobarbus ''Cheilobarbus'', commonly known as sawfins, is a small genus of freshwater ray-finned fishes belonging to the family Cyprinidae, the family which includes the carps, barbs and related fishes. The fishes in this genus are endemic to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedercypris Erubescens
The Twee River redfin (''Sedercypris erubescens'') or simply Twee redfin is a ray-finned fish species in the family Cyprinidae. It was formerly placed with the South African redfins in ''Pseudobarbus''. It is tetraploid. Its closest living relative is the Clanwilliam redfin (''S. calidus'').de Graaf ''et al.'' (2007) It is a smallish fish, just about long at sexual maturity and twice as long when fully grown. In the breeding season, males and females have the namesake red fins, but males (which are on average a bit larger) also have nuptial tubercles as is typical for cyprinids.Impson & Swartz (2007) Distribution and ecology It is endemic to the Western Cape Province of South Africa, where it occurs in the Twee River to just before its confluence with the Leeu River, and some tributaries of the former – namely the Heks, upper Middeldeur and upper Suurvlei Rivers. Some have been introduced to dams of farms, but this was too recently to determine whether they thrive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinidae
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 1,780 species divided into 166 valid genera. Cyprinids range from about 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, or ''agastric'', 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 to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

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 ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Olifants River (Western Cape)
The Olifants River () is a river in the northwestern area of the Western Cape Province of South Africa. The upper and main catchment area of the Olifants river is around Ceres and the Cederberg mountains. The Clanwilliam and Bulshoek dams are located on the river and provide water for the towns and farms along the watercourse. The river is approximately 285 km long with a catchment area of 46,220 km2. It flows into the Atlantic Ocean at Papendorp, 250 km north of Cape Town. Watershed The Olifants River rises in the Winterhoek Mountains north of Ceres. The mainstem is about 265 km long. The river flows to the north-west through a deep, narrow valley that widens and flattens into a broad floodplain below Clanwilliam. The river eventually drains into the Atlantic Ocean near Papendorp. At the mouth the Olifants river is split in two by an island that exhibits interesting rock formations. Tributaries Its main tributary is the Doring River, changing name as ...
