Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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] |
Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Batasio
''Batasio'' is a genus of catfish of the family (biology), family Bagridae. These small fish are found in fast-flowing hillstreams throughout South Asia, South and mainland Southeast Asia. Taxonomy ''Batasio'' was first described by Edward Blyth in 1860 with ''Batasio buchanani'' (a needless renaming of ''Batasio batasio'') designated as biological type, type. ''B. pakistanicus'', described in 1989, is tentatively placed in ''Batasio'', but its generic placement is questionable. Species There are currently 17 recognized species in this genus: * ''Batasio affinis'' Edward Blyth, Blyth, 1860 * ''Batasio batasio'' (Francis Buchanan-Hamilton, F. Hamilton, 1822) * ''Batasio convexirostrum'' Achom Darshan Singh, Darshan, Nongmaithem Anganthoibi, Anganthoibi & Waikhom Vishwanath, Vishwanath, 2011 * ''Batasio dayi'' (Decio Vinciguerra, Vinciguerra, 1890) * ''Batasio elongatus'' Ng Heok Hee, H.

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 ...

Bagridae
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium. Taxonomy The taxonomy of this family has changed rapidly. Nelson (2006) comments how "the family is very different from that recognized in Nelson (1994)". Claroteidae and Austroglanididae contain species that were previously bagrids. Auchenoglanididae is considered by some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mae Klong
The Mae Klong (, , ), sometimes spelled Mae Khlong or Meklong, is a river in western Thailand. The river begins at the confluence of the Khwae Noi (Khwae Sai Yok) and the Khwae Yai River (Khwae Si Sawat) in Kanchanaburi, it passes Ratchaburi Province and empties into the Gulf of Thailand in Samut Songkhram Province. The actual origin of the river is in the Tenasserim Hills, around the Khuean Srinagarindra National Park area in the north of Kanchanaburi Province. In its upper reaches, it feeds the giant Umphang Thee Lor Sue Waterfall. Environment The Mae Klong river basin has a tropical savanna climate, and is subject to two major thermal systems, the southwest and the northeast monsoons. The southwest monsoon brings moisture up from the Indian Ocean beginning in May and climaxing with heavy rains in September and October. These heavy rains are supplemented by cyclones out of the South China Sea during the same two months. The rising of the winds of the northeast monsoon ...

Khwae Noi River
The River Kwai (), more correctly Khwae Noi ( th, แควน้อย, , 'small tributary') or Khwae Sai Yok (, ), is a river in western Thailand. It rises to the east of the Salween in the north-south spine of the Bilauktaung range near, but not over the border with Burma. It begins at the confluence of Ranti, Songkalia and Bikhli Rivers. At Kanchanaburi it merges with the Khwae Yai River to form the Mae Klong River, which empties into the Gulf of Thailand at Samut Songkhram. The river is chiefly known for its association with the Pierre Boulle novel, ''The Bridge over the River Kwai'' and David Lean's film adaptation of the novel, ''The Bridge on the River Kwai'', in which Australian, Dutch, and British prisoners of war and indigenous peoples were forced by the Japanese to construct two parallel bridges spanning a river as part of the Burma Railway, also called the "Railway of Death" or "Thai-Burma Death Railway", due to the many lives lost in its construction.

Fish Of Thailand
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
