Guyanancistrus Longispinis
''Guyanancistrus longispinis'' is a species of catfish in the family Loricariidae that is of disputed classification. It is native to South America, where it occurs in the Oyapock basin in French Guiana. It is typically seen in shallow rapids with rocky substrates and moderate levels of illumination. It is known to occur alongside the species '' Guyanancistrus brevispinis'', '' Harttia fowleri'', and ''Crenicichla ternetzi'', as well as members of the genus '' Ancistrus''. The species reaches 10.4 cm (4.1 inches) in standard length and may be a facultative air-breather. ''Guyanancistrus longispinis'' was initially described as a species of ''Lasiancistrus'' in 1983. It was subsequently transferred to '' Guyanancistrus'', then to ''Pseudancistrus'', where it is still listed by sources such as FishBase FishBase is a global species database of fish species (specifically finfish).

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancistrus
''Ancistrus'' is a genus of nocturnal freshwater fish in the family Loricariidae of order Siluriformes, native to freshwater habitats in South America and Panama. Fish of this genus are common in the aquarium trade where they are known as bushynose or bristlenose catfish. In the aquarium hobby they are often referred to as bushynose or bristlenose plecos instead, but this may lead to confusion as "pleco" usually is used for ''Hypostomus plecostomus'' and its allies and is often used as a catchall term for any loricariids remotely resembling that species. Taxonomy The type species is ''Ancistrus cirrhosus''. This genus is the largest genus within the tribe Ancistrini. The name ancistrus derives from the Ancient Greek ''agkistron'' "hook" – a reference to the form of the cheek odontodes. The genera ''Pristiancistrus'', ''Thysanocara'' and ''Xenocara'' are now synonyms of ''Ancistrus''. Description ''Ancistrus'' species show all the typical features of the Loricariidae. T ...

Hypostominae
The Hypostominae are a subfamily of catfishes of the family Loricariidae. Most members are restricted to tropical and subtropical South America, but there are also several species (in genera ''Ancistrus'', '' Chaetostoma'', ''Lasiancistrus'', '' Leptoancistrus'' and ''Hemiancistrus'') in southern Central America. ''Hypostomus plecostomus'', which is popular in the aquarium trade, has been introduced to several regions far from its native range. Studies conducted with representatives of some genera of Hypostominae showed, within this group, the diploid number ranges from 2n = 52 to 2n = 80. However, the supposed wide karyotypic diversity the family Loricariidae or the subfamily Hypostominae would present is almost exclusively restricted to the genus ''Hypostomus'', and the species from the other genera had a conserved diploid number.

Pseudancistrus
''Pseudancistrus'' is a genus of suckermouth armored catfishes native to South America. Taxonomy ''Pseudancistrus'' is a genus in the tribe Ancistrini of the subfamily Hypostominae. It was described by Pieter Bleeker in 1862, and redescribed by Jonathan Armbruster in 2004. Currently, there are 18 recognized species distributed in northern South America, with the inclusion of the genera ''Lithoxancistrus'', the species formerly known as ''Hemiancistrus megacephalus'', as well as the recently described ''Pseudancistrus corantijniensis''. There is no single morphological feature which distinguishes the group from related genera. Despite this, ''Pseudancistrus'' is generally recognized as a monophyletic group. Within the genus there is what is called the ''P. barbatus'' group. This group comprises Guyanese derived ''Pseudancistrus'' bearing hypertrophied odontodes along the snout and nonevertible cheek plates. It includes the five species ''P. barbatus'', ''P. corantijniensis'', '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lasiancistrus
''Lasiancistrus'' is a genus of suckermouth armored catfishes. They are native to South America and Panama. Taxonomy ''Lasiancistrus'' was first described as a subgenus of ''Ancistrus'' in 1904, including ''A. heteracanthus'', ''A. pictus'', ''A. mystacinus'', and ''A. guacharote''. Later, it was raised to genus level, and several unrelated species were included. Many of these species have since been moved to other genera, such as ''Pseudolithoxus''. Most ''Lasiancistrus'' species had been described from few specimens; the genus was revised in 2005, synonymizing many of the existing species into four species, ''L. caucanus'', ''L. guacharote'', ''L. heteracanthus'', and ''L. schomburgkii''. ''L. maracaiboensis'' and ''L. mystacinus'' are synonyms of ''L. guacharote''. ''L. castelnaui'', ''L. caquetae'', ''L. guapore'', ''L. multispinis'', ''L. pictus'', and ''L. scolymus'' are synonyms of ''L. schomburgkii''.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guyanancistrus Brevispinis
''Guyanancistrus brevispinis'' is a species of catfish in the family Loricariidae. It is a freshwater fish native to South America, where it occurs in the Atlantic coastal drainages of the Guianas, ranging from the Nickerie River basin to the Oyapock basin in French Guiana and Suriname. It has also been reported from Guyana, but this is believed to be a misidentification. The species is considered the most common and abundant member of the genus ''Guyanancistrus'', occurring in rocky streams with flowing water, especially in the vicinity of plunging waters. It is known to coexist with members of the genus ''Lithoxus'' in small forested creeks as well as rapids. The species reaches 14.2 cm (5.6 inches) in standard length. ''Guyanancistrus brevispinis'' appears in the aquarium trade, where it is often referred to either as the shortspined wing pleco or by its associated L-number The L-number system is a semi-scientific classification system of catfish based on photogr ...
