Baryancistrus Demantoides
''Baryancistrus demantoides'' is a species of armored catfish endemic to Venezuela. It reaches a length of SL. It lives around granite rocks in flowing water, in the upper parts of Orinoco River. The colour is green-brown with yellow spots on the head and parts of the body. The dorsal fin is connected to the adipose fin, a feature that distinguishes this species from the rest of the Ancistrini, except ''Baryancistrus niveatus'', ''Parancistrus'' and ''Spectracanthicus''.

In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, D ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...

Fish Of Venezuela
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 fis ...

Hemiancistrus Subviridis
''Hemiancistrus subviridis'', the green phantom pleco, is a species of armored catfish from the family Loricariidae, commonly found in Venezuela. Within Venezuela, it is native to the Orinoco and Casiquiare drainage basins, where it is usually found among granitic rocks in flowing water. The species reaches 15 cm (5.9 inches) SL.

L-number
The L-number system is a semi-scientific classification system of catfish based on photographs of shipments of tropical catfish of the family Loricariidae published by the German aquarium magazine DATZ (Die Aquarien- und Terrarienzeitschrift (The Aquarium and Terrarium Magazine)). The first L-number was published in 1988. An L-number is not a formal scientific designation, but it allows people to identify various loricariid catfish by a "common name" before the fish is officially described. When a loricariid receives an official scientific name, the L-number (or numbers) is retired; best practice is then to use the scientific name. A specific L-number classification does not guarantee a discrete species, multiple L numbers have been given to different populations of the same species. To add to the confusion, sometimes a single L-number may be used for multiple species. Additionally the aquarium magazine 'Das Aquarium' introduced a similar system using the prefix 'LDA'.

Parancistrus
''Parancistrus'' is a small genus of suckermouth armored catfishes native to South America. Taxonomy Three species - ''Hypostomus aurantiacus'', ''H. nigricans'' and ''H. vicinus'' - were described by François Louis de la Porte, comte de Castelnau in 1855. ''Parancistrus'' was described by Pieter Bleeker in 1862 and ''P. aurantiacus'' designated as type. Later, ''P. nigricans'' and ''P. vicinus'' were deemed to be synonyms of ''P. aurantiacus'', making ''P. aurantiacus'' the only species of ''Parancistrus'' until ''P. nudiventris'' was described in 2005. Species There are currently two recognized species in this genus: * ''Parancistrus aurantiacus'' ( Castelnau, 1855) * ''Parancistrus nudiventris'' Rapp Py-Daniel & Zuanon, 2005 Appearance and anatomy ''Parancistrus'' is unique among loricariids due to the presence of fleshy folds on the naked area around the dorsal fin and at the pectoral fin points insertion in the breeding males.

Ancistrini
Ancistrini is a tribe of catfishes of the family Loricariidae. Most are restricted to tropical and subtropical South America, but there are also several genus (''Ancistrus'', ''Chaetostoma'', '' Hemiancistrus'' and '' Lasiancistrus'') in southern Central America. Taxonomy Ancistrini have previously been considered a loricariid subfamily. However, the subfamily Hypostominae would be paraphyletic if Ancistrinae continued to be recognized. To continue recognizing the monophyly of this group while returning it to Hypostominae, Hypostominae was broken into several tribes. Pterygoplichthyini is sister to the tribe Ancistrini, which shares the derived presence of an evertible patch of plates on the cheek. Description Most Ancistrini species (except for some '' Pseudancistrus'' and '' Spectracanthicus'') can be separated from all other loricariids except the Pterygoplichthyini by the presence of evertible cheek plates with hypertrophied odontode Odontodes, or dermal teeth, are hard ...

Adipose Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Orinoco River
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers , with 76.3 percent of it in Venezuela and the remainder in Colombia. It is the fourth largest river in the world by discharge volume of water. The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado–Chalbaud, in the Parima range, was not explored until 453 years later, in 1951. The source, near the Venezuelan–Brazilian border, at ab ...
