Andeancistrus Platycephalus
''Andeancistrus platycephalus'' is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Zamora River basin, which is part of the upper Marañón River, Marañon River drainage in Ecuador. The species reaches 14.5 cm (5.7 inches) in total length. The species was known as ''Cordylancistrus platycephalus'' until a 2015 reclassification, when Nathan K. Lujan, Vanessa Meza-Vargas, and Ramiro Barriga-Salazar constructed the genera ''Andeancistrus'' and ''Transancistrus''.''Lujan, N.K., Meza-Vargas, V. & Barriga-Salazar, R.

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...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] |
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 '' ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern Subregion#Americas, subregion of a single continent called Americas, America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest.

Zamora River
The Zamora River ( Spanish: ''Río Zamora'') is a tributary of the Santiago River located in the south-east of Ecuador. Historically, it was known to the Spanish as ''Yaya Mayu'' ("Father River"), from the river's name among a group of Shuar encountered nearby. The sources of the Zamora River are in the Podocarpus National Park, specifically at the Nudo de Cajanuma. The river then descends towards the city of Loja. It crosses the provinces of Loja, Zamora-Chinchipe (wherein lies the city of Zamora) and Morona-Santiago, where it empties into the Santiago. Tributaries The Zamora is the dominant river in southeastern Ecuador, and has many tributaries, perhaps the source of its native name . The most significant tributaries by province include: ;Loja Province * Malacatos River * Jipiro River * Zamora Huayco River ;Zamora-Chinchipe Province * Tambo Blanco River * San Francisco River * Sabanilla River * Bombuscaro River * Jamboé River * Nambija River * Yacuambi River * Chica� ...

Cordylancistrus
''Cordylancistrus'' is a genus of suckermouth armored catfish native to South America. It is much the same as ''Chaetostoma''. The few differences are a wider head, longer cheek odontodes, and plates on the snout. ''Cordylancistrus'' can be found in rivers and streams high in the Andes, from Venezuela to Colombia.

Fish Described In 1898
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 fis ...
