Pseudoplatystoma
''Pseudoplatystoma'' is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams. Nomenclature ''Pseudoplatystoma'' is a monophyletic genus of catfishes. ''P. fasciatum'' was the first species to be described, under the name ''Siluris fasciatus''. In 1829, ''P. corruscans'' was described under the name ''Platystoma corruscans'', and over a decade later, ''P. tigrinum'' was described as ''Platystoma tigrinum''. In 1862, ''Pseudoplatystoma'' was described and these species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemisorubim
The porthole shovelnose catfish or spotted shovelnose catfish, ''Hemisorubim platyrhynchos'', is the only species in the genus ''Hemisorubim'' of the catfish (order Siluriformes) family Pimelodidae. Taxonomy This fish is considered one of the "sorubimine" catfishes, an informal group of catfish that includes genera such as '' Sorubim'', ''Pseudoplatystoma'', and '' Brachyplatystoma''. This genus forms a monophyletic group with '' Sorubim'', ''Sorubimichthys'', ''Pseudoplatystoma'', and '' Zungaro''. Of these genera, ''Hemisorubim'' is most closely related to ''Pseudoplatystoma''. Distribution This species is native to South America and originates from the Amazon, Maroni, Orinoco, and Paraná River basins. It also occurs in the Pantanal. Appearance and anatomy This fish reaches a length of SL and weighs up to 1,470 grams (3.23 lb). It is the sixth largest Pimelodid in the Pantanal. Its body shape and color pattern are perfectly adapted to the muddy bottom where they inhabit. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Pimelodidae
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes (order Siluriformes). Taxonomy The family Pimelodidae has undergone much revision. Currently, it contains about 30 genera and about 90 recognized and known but unnamed species. Wikipedia lists 109 species in this family. The low-eye catfish (previously family Hypophthalmidae), and thus the genus '' Hypophthalmus'', which contains four species, was reclassified with the pimelodids. This family previously included fish that are now classified under Pseudopimelodidae (previously subfamily Pseudopimelodinae) and Heptapteridae (previously subfamily Rhamdiinae). This family also previously included '' Conorhynchos conirostris'', currently ''incertae sedis''. However, a molecular analysis has shown unequivocal support for monophyly of the individual families and the genus ''Conorhynchos'' into a clade called Pimelodoidea, including Pimelodidae + Pseudopimelodidae and Heptapteridae + ''Conorhynch ...

Cladistics
Cladistics ( ; from Ancient Greek 'branch') is an approach to Taxonomy (biology), biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived (phylogenetics), derived characteristics (synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose Phenotypic trait, character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used Paraphyly, paraphyletically, outside of cladistics, e.g. as a 'E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Occiput
The occipital bone () is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone lies over the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is described in terms of separate parts. From its front to the back is the basilar part, also called the basioccipital, at the sides of the foramen magnum are the lateral parts, also called the exoccipitals, and the back is named as the squamous part. The basilar part is a thick, somewhat quadrilateral piece in front of the foramen magnum and directed towards the pharynx. The squamous part is the curved, expanded plate behind the foramen magnum and is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquarium Hobby
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. It is a practice that encompasses the art of maintaining one's own aquatic ecosystem, featuring a lot of variety with various water systems, all of which have their own unique features and requirements. Fishkeeping primarily serves as a token of appreciation and fascination for marine life and the environment that surrounds such, along with other purposes such as the piscicultural fishkeeping industry, serving as a branch of agriculture, being one of the most widespread methods of cultivating fish for commercial profit. Origins of fishkeeping Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many cultures, ancient and modern, have kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-caught fish in ...

Peruvian Spanish
Peruvian Spanish () is a family of dialects of the Spanish language that have been spoken in Peru since its introduction by Spanish conquistadors in 1532. There are five varieties spoken in the country, by about 94.4% of the population. The five Peruvian dialects are Andean Spanish, Peruvian Coastal Spanish, Andean-Coastal Spanish, Equatorial Spanish, and Amazonic Spanish. History The Spanish language first arrived in Peru in 1532. During colonial and early republican times, the Spanish spoken colloquially on the coast and in the cities of the highland possessed strong local features, but as a result of dialect leveling in favor of the standard language, the language of urban Peruvians today is more or less uniform in pronunciation throughout most of the country. Vestiges of the older dialect of the coast can be found in the speech of Afro-Peruvians, which retains Andalusian features such as the aspiration or deletion of final /s/ and the deletion of final /r/. The dialect o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
