Apure
Apure State ( es, Estado Apure, ) is one of the 23 states of Venezuela. Its territory formed part of the provinces of Mérida, Maracaibo, and Barinas, in accordance with successive territorial ordinations pronounced by the colonial authorities. In 1824 the Department of Apure was created, under jurisdiction of Barinas, which laid the foundations for the current entity. In 1856 it separated from Barinas and for the first time Apure appeared as an independent province, which in 1864 acquired the status of state. In 1881, however, a new territorial division combined Apure and Guayana to form a single state named ''Bolívar.'' In 1899 it reestablished its autonomy and finally, by means of the Constitution of 1909, gained its current borders. The territory was famous for heron plumes, which adorned European courts. At the same time, it was the scene of armed encounters that marked the evolution of the War for Independence, as well as numerous battles during the civil war ...

Catfish Genera
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] |
Fish Of South America
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. Most f ...

Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C. Grier (2008) "Pet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astyanax Meunieri
In Greek mythology, Astyanax (; grc, Ἀστυάναξ ''Astyánax'', "lord of the city") was the son of Hector, the crown prince of Troy, and his wife, Princess Andromache of Cilician Thebe."Astyanax". ''Oxford Classical Dictionary''. Oxford, 1949, p. 101 (''s.v.'' "Ἀνδρομάχη"). His birth name was Scamandrius (in Greek: Σκαμάνδριος Skamandrios, after the river Scamander''A Classical Manual: Being a Mythological, Historical, and Geographical Commentary on Pope's Homer and Dryden's Aeneid of Virgil''. J. Murray, 1833, p. 189.), but the people of Troy nicknamed him Astyanax (i.e. high king, or overlord of the city), because he was the son of the city's great defender (''Iliad'' VI, 403) and the heir apparent's firstborn son. During the Trojan War, Andromache hid the child in Hector's tomb, but the child was discovered. His fate was debated by the Greeks, for if he were allowed to live, it was feared he would avenge his father and rebuild Troy. In the versi ...

Pimelodella Cristata
''Pimelodella'' is a genus of three-barbeled catfishes. ''Pimelodella'' is the largest genus in the family. However, it is in need of taxonomic revision. This genus is found on both sides of the Andes, ranging from Panama to Paraguay and southern Brazil. With the exception of ''P. chagresi'', all members of the genus are restricted to South America. This genus includes two species of troglobitic catfishes, ''P. kronei'' and ''P. spelaea''.

Bryconops Caudomaculatus
The tailspot tetra (''Bryconops caudomaculatus'') is a freshwater fish that lives in the coastal river regions of upper South America. Both its common and scientific names reference the distinct spot of color present on the tail fin, which is one of its defining characteristics. It is a small fish, reaching 4.8 in (12.4 cm) at its longest. Despite its small size, it is an active swimmer, with a preference for fast-flowing waters. Description The tailspot tetra, like the rest of the genus ''Bryconops'', has a slender body described as "smelt-like", similar to members of sister genus ''Piabucus''. It reaches 4.8 in (12.4 cm) in total length (with the tail fin included), and a corresponding weight of 20.1 grams. Its back scales are tinted orange to dark-orange, fading into silver on the belly when the fish is alive. Upon close inspection, the scales are also revealed to have a scattering of minute dots. The spot of bright orange on the basal half of the caudal fin is what gives th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
