Acanthocobitis Longipinnis
''Acanthocobitis longipinnis'' is a species of freshwater ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is known from a single specimen, the holotype, which was collected from the Ganges. This species was first formally described in 1861 by the German naturalist and explorer Wilhelm Peters and Peters proposed the new genus ''Acanthocobitis''. Later authors treated this species as a synonym of '' Cobitis pavonacea'' but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that ''A. longipennis'' was a valid species and that it was one of two species of loach in the genus ''Acanthocobitis'', alongside ''A. pavonacea'', with the other species being classified in the genus ''Paracanthocobitis''. This species is the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthocobitis
''Acanthocobitis'' is a genus of freshwater ray-finned fish of the stone loach family, Nemacheilidae. Recent work has suggested that the genus be split into two with the former subgenus '' Paracanthocobitis'' being raised to a full species, leaving just the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ..., '' Acanthocobitis pavonacea'', in the current genus.

Fish Described In 1861
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 ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Paracanthocobitis
''Paracanthocobitis'' is a genus of freshwater Actinopterygii, ray-finned fishes belonging to the Family (biology), family Nemacheilidae, the stone loaches. This genus is known from the Indus River, Indus basin in Pakistan to the Mekong River, Mekong basin of Cambodia and Laos The type species is ''Paracanthocobitis zonalternans''. Some authorities treat this as a subgenus of ''Acanthocobitis'' Species These are the currently recognised species in this genus: * ''Paracanthocobitis abutwebi'' Randal Anthony Singer, R. A.

Acanthocobitis Pavonacea
''Acanthocobitis pavonacea'', also known as the spearfin loach, is a species of ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is found in the Brahmaputra River of Assam. This is one of two species in the genus ''Acanthocobitis'', alongside the type species, '' A. longipinnis''. ''A. longipennis'' was treated as synonym of this species but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that ''A. longipennis'' was a valid species and that it was one of two species ofloach in the genus ''Acanthocobitis'', alongside ''A. pavonacea'', with the other species being classified in the genus ''Paracanthocobitis''.

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, 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 Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explorer
Exploration is the process of exploring, an activity which has some Expectation (epistemic), expectation of Discovery (observation), discovery. Organised exploration is largely a human activity, but exploratory activity is common to most organisms capable of directed Animal locomotion, locomotion and the ability to learn, and has been described in, amongst others, social insects foraging behaviour, where feedback from returning individuals affects the activity of other members of the group. Types Geographical Geographical exploration, sometimes considered the default meaning for the more general term exploration, is the practice of discovering lands and regions of the planet Earth remote or relatively inaccessible from the origin of the explorer. The surface of the Earth not covered by water has been relatively comprehensively explored, as access is generally relatively straightforward, but underwater and subterranean areas are far less known, and even at the surface, much is ...
