Corydoras
''Corydoras'' is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where ''Corydoras'' is not present. ''Corydoras'' species are distributed in South America where they can be found from the east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in northern Argentina. Species assigned to ''Corydoras'' display a broad diversity of body shapes and coloration. ''Corydoras'' are small fish, ranging from in SL., and are protected from predators by their body armor and by their sharp, typically venomous spines. Taxonomy The name ''Corydoras'' is derived from the Greek ''kory'' (helmet) and ''doras'' (skin). ''Corydoras'' is by far the largest genus of Neotropical fishes with more than 160 species. It is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corydoras Sterbai
Sterba's corydoras (''Corydoras sterbai'') is a member of the South American ''Corydoras'' genus of freshwater aquarium catfish and one of the most popular species of ''Corydoras'' due to its attractive markings. The fish is native to the Guaporé River region between Bolivia and Brazil. Sterba's cory is distinguishable from other ''Corydoras'' species as it has white spots on a black background on its head. It is occasionally confused with '' Corydoras haraldschultzi''; the difference is that the latter has a pattern of black dots on a white background on the head. ''C. sterbai'' has recently become available in an albino form and a black form. Like many ''Corydoras'' species, Sterba's corydoras is a shoaling catfish, and thus should ideally be kept in groups of 5 or more. In the wild it can be found in Brazil and thus, wild caught fish prefer soft, acidic water. However, Sterba's corydoras is a hardy fish and tank bred specimens have adapted to a wider range of water co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corydoradinae
Callichthyidae is a family of catfishes (order Siluriformes), called armored catfishes due to the two rows of bony plates (or scutes) along the lengths of their bodies. It contains some of the most popular freshwater aquarium fish, such as many species in the genus '' Corydoras''. Taxonomy The family derives its name from the Greek words ''kallis'' (beautiful) and ''ichthys'' (fish). Callichthyidae is one of six families in the superfamily Loricarioidea, and is sister to a clade formed by Scoloplacidae, Astroblepidae, and Loricariidae. Within the family Callichthyidae, the two subfamilies have eight genera and about 177 species, accounting for about 7% of all catfish. Most of these species are in the genus ''Corydoras'', the largest catfish genus. The subfamily Corydoradinae includes about 90% of the species in the family Callichthyidae and is one of the most diverse siluriform assemblages in the Neotropics, with about 170 valid species. It includes two tribes, Aspidoradini and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catfish
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] |
Scleromystax
''Scleromystax'' is a genus of fish in the family Callichthyidae endemic to small tributaries from several coastal river basins draining the southern and southeastern regions in Brazil. Most of the species of ''Scleromystax'' are highly sexually dimorphic; males have developed odontodes inserted in fleshy papillae on the preopercular-opercular region and the dorsal and pectoral fins are 2–3 times as long as those of females. ''S. salmacis'' is an exception, as its sexually dimorphic features are subtle and non-remarkable. Taxonomy The species of ''Scleromystax'' were previously classified within the genus '' Corydoras''. However, ''Scleromystax'' species are now thought to be more closely related to ''Aspidoras'' in a tribe called Aspidoradini.Britto, M.R.

Greek Language
Greek ( el, label= Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy ( Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works ...

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 ro ...
