''C. diphyes'' is inedible to many species due to its bony armor and so individual ''O. mimulus'' that look more similar to ''C. diphyes'' are less likely to be eaten by predators like '' Crenicichla lepidota''. ''O. mimulus'' is named for its mimicry of ''C. diphyes''.Axenrot, Thomas E., and Sven O. Kullander.

Sven Oscar Kullander
Sven Oscar Kullander (born 30 November 1952 in Sollefteå) is a Sweden, Swedish biologist specialised in ichthyology. He primarily researches cichlids – notably the genus ''Apistogramma'' and the ''Cichlasoma''-complex – and other tropical fresh water fishes. He also has been working with Endangered species, endangered fish species in Sweden. He studied at the universities of Umeå University, Umeå and Stockholm University, Stockholm, and took his Doctor of Philosophy, Ph.D. in Stockholm in 1984. He is currently senior curator at the Swedish Museum of Natural History in Stockholm, with the responsibility for the ichthyologic and Herpetology, herpetologic collections. Kullander also coordinates the museum's contributions to FishBase. Kullander has produced more than 100 scientific and popular publications on fishes, and described many groups and new species of cichlids. The Swedish aquarists' magazine ''Tidskriften Akvariet'' gave him "Akvariets Oscar" ("the Aquarium Acade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loricariidae
The Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as " plecos", notably the suckermouth catfish, ''Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, or armoured catfish. The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called ''Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", such as ''Farlowella'' catfish. In their native range, these fish are known as ''cascudos'' ...

Paraná River
The Paraná River ( es, Río Paraná, links=no , pt, Rio Paraná, gn, Ysyry Parana) is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some ."Parana River".

Encyclopædia Britannica Inc., 2012. Web. 26 May. 2012 Among South American rivers, it is second in length only to the Amazon River. It merges with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean. The first European to go up the Paraná River was the Venetian explorer Sebastian Cabot, in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low.

Batesian Mimicry
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil. Batesian mimicry is the most commonly known and widely studied of mimicry complexes, such that the word mimicry is often treated as synonymous with Batesian mimicry. There are many other forms however, some very similar in principle, others far separated. It is often contrasted with Müllerian mimicry, a form of mutually beneficial convergence between two or more harmful species. However, because the mimic may have a degree of protection itself, the distinction is not absolute. It can also be contrasted with functionally different forms of mimicry. Perhaps the sharpest contrast here is with aggressive mimicry where a predator or parasite mimics a harmless species, avoiding detection and improving its ...

Hypoptopomatini
The Hypoptopomatinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae, composed of 17 genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species. It has been divided into two tribes, Hypoptopomatini and Otothyrini. However, in a 2005 analysis, Otothyrini was found to not be monophyletic, with its representatives comprising a paraphyletic group in relation to the tribe Hypoptopomatini. More recent phylogenetic evidence shows that Hypoptopomatini and Otothyrini, while each are monophyletic tribes, do not form a monophyletic subfamily, and therefore should each be recognized as their own individual subfamilies. Problematically, the most recent hypoptopomatine genera, '' Gymnotocinclus'' and ''Rhinolekos'', were not classified in either of the tribes. Almost all species of Hypoptopomatinae have a diploid number of 2n = 54; this group is karyotypically very conserved. Hypoptopomatinae are distributed east of t ...

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 ...

Taxa Named By Thomas Erik Axenrot
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
