Micromyzon Orinoco
''Micromyzon orinoco'' is a species of catfish (order Siluriformes) in the family Aspredinidae. Distribution and habitat ''M. orinoco'' can be found in the main channel of lower Orinoco River in Venezuela near the town of Ciudad Guayana. They live on the sandy and muddy bottom of the river, at depths from 10 to 18 meters. Description This species of the aspredinid catfish tribe Hoplomyzontini Micromyzon, was originally collected in expeditions led in 1978-79. This species differs from Micromyzon akamai in a number of particular physical and skeletal features but shares its small size and lack of eyes. To identify this species, the examination and comparison process took nearly 40 years due to the rare and elusive nature of the species. They originally captured only two specimens. Its size, of less than 1 inch in length, added to the challenge of capture and identification. High-Resolution X-ray Computed Tomography Tomography is imaging by sections or sectioning that u ...

Micromyzon Akamai
''Micromyzon akamai'' is a species of catfish (order Siluriformes) in the family Aspredinidae. Taxonomy This genus and species were first described in 1996. This species is sister to a clade formed by '' Dupouyichthys'' and ''Ernstichthys''. Distribution and habitat ''M. akamai'' appears to have a patchy distribution. It has been found in the Amazon River basin as well as the lower Tocantins River. ''M. akamai'' inhabits channels of the white-water rivers on sandy substrates at a depth of about 5–20 metres (16–66 ft). They have never been found in marginal habitats such as beaches or in small streams. Description This species is a miniature species, with its maximum observed length being less than 16 millimetres (.63 in) SL. With females reaching sexual maturity between 11–16 mm (.43–.63 in), they are the smallest sexually mature aspredinids known. This hoplomyzontine aspredinid is distinguished by the lack of eyes, ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspredinidae
The Aspredinidae are a small South American family of catfishes ( order Siluriformes) also known as the banjo catfishes, with about 43 species. Distribution Aspredinids are found throughout the major tropical rivers of South America (e.g., Magdalena, Orinoco, Amazon, São Francisco, Paraguay- Paraná, and Uruguay). ''Bunocephalus'' is the only genus found in rivers west of the Andes including the Atrato, San Juan, and Patía Rivers. Taxonomy Of the 13 genera in the family Aspredinidae, a few genera have been described relatively recently, including ''Acanthobunocephalus'' in 1995, ''Micromyzon'' in 1996, and ''Pseudobunocephalus'' in 2008. These genera are categorized into three subfamilies. The Aspredinidae are often recognized as a part of the primarily Asian superfamily Sisoroidea as the sister group to the family Erethistidae. However, other authors find that they are sister to the superfamily Doradoidea, which includes Doradidae, Auchenipteridae, and perhaps Mochokidae. ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...

Siluriformes
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of Actinopterygii, ray-finned fish. Named for their prominent barbel (anatomy), 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 Brachyplatystoma filamentosum, piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasite, parasitic species commonly called the Candiru (fish), 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 Aquaculture of catfish, farmed or fished for food. Many of the smaller species, partic ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Orinoco
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers , with 76.3 percent of it in Venezuela and the remainder in Colombia. It is the fourth largest river in the world by discharge volume of water. The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado–Chalbaud, in the Parima range, was not explored until 453 years later, in 1951. The source, near the Venezuelan–Brazilian border, at ab ...
