Lamontichthys
''Lamontichthys'' is a genus of Loricariidae, armored catfishes native to South America. Taxonomy The phylogenetics, phylogenetic position of ''Lamontichthys'' remains uncertain. It has been considered to be cladistics, sister to ''Harttia'', whereas ''Lamontichthys'' shows much more similarities with ''Pterosturisoma microps'' of the monotypic genus ''Pterosturisoma'', which only differs from ''Lamontichthys'' by the number of pectoral fin rays.

Pterosturisoma
''Pterosturisoma microps'' is the only species of the monotypic genus ''Pterosturisoma'', a genus of the family Loricariidae of catfish (order Siluriformes). This species is endemic to Peru where it is found in the upper Amazon basin. ''P. microps'' is a rheophile, which means it likes fast-moving water. ''Pterosturisoma microps'' reaches a length of SL. ''Pterosturisoma'' appears morphologically very similar to ''Lamontichthys''; however, ''Pterosturisoma'' has 6 pectoral fin rays while ''Lamontichthys'' has 7. These two genera share features with ''Sturisoma'' such as similar body depth at the dorsal fin origin, the presence of filamentous extensions on caudal 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 se ... spines, and complete abdominal plate cover that extends to the ...

Lake Maracaibo
Lake Maracaibo (Spanish: Lago de Maracaibo; Anu: Coquivacoa) is a lagoon in northwestern Venezuela, the largest lake in South America and one of the oldest on Earth, formed 36 million years ago in the Andes Mountains. The fault in the northern section has collapsed and is rich in oil and gas resources. It is Venezuela's main oil producing area and an important fishing and agricultural producing area. It is inhabited by a quarter of the country's population and is also the place with the most frequent lightning on earth. The famous Catatumbo lightning can illuminate nighttime navigation, and eutrophication caused by oil pollution is a major environmental problem facing the lake. Geography Lake Maracaibo is located in the Maracaibo lowland in the faulted basin between the Perija Mountains and the Merida Mountains of the Eastern Cordillera Mountains in northwestern Venezuela. The lake is in the shape of a vase. It is 210 kilometers long from north to south, 121 kilometers wide from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harttiini
Loricariinae is a subfamily of the family Loricariidae of catfish (order Siluriformes). This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species (in genera '' Crossoloricaria'', '' Dasyloricaria'', '' Fonchiiichthys'', '' Rineloricaria'', '' Spatuloricaria'', ''Sturisoma'' and '' Sturisomatichthys'') in Panama and a single (''Fonchiiichthys'') in Costa Rica.Angulo; Garita-Alvarado; Bussing; and López (2013). Annotated checklist of the freshwater fishes of continental and insular Costa Rica: additions and nomenclatural revisions.'' Check List 9(5): 987–1019. Taxonomy Loricariinae was first described in 1831. Later, in 1979, many genera were described and Loricariinae was divided into four subfamilies: Loricariini, Harttiini, Farlowellini, and Acestridiini. Eventually, the genera of Acestridiini was included under Hypoptopomatinae and genera of Farlowellini was reclassified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectoral 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 ...

Odontode
Odontodes, or dermal teeth, are hard structures found on the external surfaces of animals or near internal openings. They consist of a soft pulp surrounded by dentine and covered by a mineralized substance such as enamel, a structure similar to that of teeth. They generally do not have the same function as teeth, and are not replaced the same way teeth are in most fish. In some animals (notably catfish), the presence or size of odontodes can be used in determining the sex. Odontodes typically cover the body of chondrichthyans (cartilaginous fishes), while mineralized dermal scales are characteristic of bony fishes. During the evolution to bony fishes, ancestral odontodes have been modified to become dermal scales, including elasmoid scales in teleosteans. Etymology The name comes from the Greek "''odous, gen. The Book of Genesis (from Greek language, Greek ; Hebrew language, Hebrew: בְּרֵאשִׁית ''Bəreʾšīt'', "In hebeginning") is the first book of the Hebrew ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
