Chiloglanis Frodobagginsi
''Chiloglanis frodobagginsi'' is a species of catfish native to West Africa, in particular the upper Niger River. First described in 2023, it was initially mistaken for its sister species, '' Chiloglanis micropogon''. Etymology ''Chiloglanis frodobagginsi'' was named after Frodo Baggins, a fictional character that appears in the English novel J. R. R. Tolkien's fantasy novel ''The Lord of the Rings'' and other related media. Description ''Chiloglanis frodobagginsi'' is a small species of ''Chiloglanis'' with a maximum standard length of 38.1 mm. The species exhibits sexual dimorphism, specifically in the urogenital papilla, in which those of males are elongated while female papillae are reduced. Tubercles are present, with higher concentrations near the head. These tubercles are white, while the body is medium-brown with light-brown marks.

Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niger River
The Niger River ( ; ) is the main river of West Africa, extending about . Its drainage basin is in area. Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border. It runs in a crescent shape through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive River delta, delta, known as the Niger Delta, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River.

Sister Species
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Frodo Baggins
Frodo Baggins ( Westron: ''Maura Labingi'') is a fictional character in J. R. R. Tolkien's writings and one of the protagonists in ''The Lord of the Rings''. Frodo is a hobbit of the Shire who inherits the One Ring from his cousin Bilbo Baggins, described familiarly as "uncle", and undertakes the quest to destroy it in the fires of Mount Doom in Mordor. He is mentioned in Tolkien's posthumously published works, '' The Silmarillion'' and '' Unfinished Tales''. Frodo is repeatedly wounded during the quest and becomes increasingly burdened by the Ring as it nears Mordor. He changes, too, growing in understanding and compassion, and avoiding violence. On his return to the Shire, he is unable to settle back into ordinary life; two years after the Ring's destruction, he is allowed to take ship to the earthly paradise of Valinor. Frodo's name comes from the Old English name '' Fróda'', meaning "wise by experience". Commentators have written that he combines courage, selflessn ...

Chiloglanis
''Chiloglanis'' is a genus of upside-down catfishes native to Africa. These species have modified lips and barbels that form a suckermouth. They also have a naked (scaleless) body. Sexual dimorphism has been reported in ''Chiloglanis''. The adult males of many of these species have elongate anal and caudal fins. Also, males may have an enlarged humeral process. Species There are currently 53 recognized species in this genus: * '' Chiloglanis angolensis'' Poll, 1967 * '' Chiloglanis anoterus'' R. S.

Standard Length
Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery 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 Glossary of ichthyology#H, hypural plate. This measurement excludes the length of the caudal fin, 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 Actinopterygii, bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys) and usually Elasmobranchii (shark ...

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urogenital Papilla
The genital papilla is an anatomical feature of the external genitalia of some animals. In mammals In mammals, the genital papilla is a part of the vulva not present in humans, which appears as a small, fleshy flab of tissue. The papilla covers the opening of the vagina.Laboratory Manual for General Biology 5th Edition In fish The genital papilla (urogenital/genital pore) is a small, fleshy tube behind the anus present in most teleost Teleostei (; Ancient Greek, Greek ''teleios'' "complete" + ''osteon'' "bone"), members of which are known as teleosts (), is, by far, the largest group of ray-finned fishes (class Actinopterygii), with 96% of all neontology, extant species of f ... fish, from which the sperm or eggs are released; the sex of a fish often can be determined by the shape of its papilla.

Tubercle
In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal. In plants A tubercle is generally a wart-like projection, but it has slightly different meaning depending on which family of plants or animals it is used to refer to. In the case of certain orchids and cacti, it denotes a round nodule, small eminence, or warty outgrowth found on the lip. They are also known as podaria (singular ''podarium''). When referring to some members of the pea family, it is used to refer to the wart-like excrescences that are found on the roots. In fungi In mycology, a tubercle is used to refer to a mass of hyphae from which a mushroom is made. In animals When it is used in relation to certain dorid nudibranchs such as '' Peltodoris nobilis'', it means the nodules on the dorsum of the animal. The tubercles in nudibranchs can present themselves in different way ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
