Pangasius Silasi
''Pangasius silasi'' is a species of the Pangasiidae family, endemic to the Krishna River in India. Etymology Pangasius Silasi was named in honor of Eric Godwin Silas (1928-2018), a Sri Lankan-born Indian ichthyologist and fisheries scientist Description ''Pangasius silasi'' differs from ''Pangasius pangasius'' by having vomero-palatal teeth confluent as an uninterrupted curved band as opposed to two lunate vomeropalatal teeth patches on each side with a wide gap in the centre and 48 vertebrae as opposed to 44. Nutritional value ''Pangasius silasi'', like other species in the genus ''Pangasius ''Pangasius'' is a genus of medium-large to very large shark catfishes native to fresh water in South and Southeast Asia.

Shark Catfish
The shark catfishes form the family Pangasiidae. They are found in fresh and brackish waters across southern Asia, from Pakistan to Borneo. Among the 30-odd members of this family is the plant-eating, endangered Mekong giant catfish ''Pangasianodon gigas'', one of the largest known freshwater fish. Several species are the basis of productive aquaculture industries in Vietnam's Mekong Delta. Taxonomy and fossil record Although Pangasiidae forms a monophyletic group, several studies indicate this group may actually be a subtaxon nested within the family Schilbeidae. Thus, Pangasiidae's familial status may not deserve continued recognition. Two fossil pangasiid species are described, '' Cetopangasius chaetobranchus'' from the Miocene, and '' Pangasius indicus'', from the Eocene. However, the reported age of ''P. indicus'' from the Eocene is debatable, as the Sipang Fauna stratum where it is found has never been officially dated. Therefore, the earliest reliable pangasiid foss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Eric Godwin Silas
The given name Eric, Erich, Erikk, Erik, Erick, Eirik, or Eiríkur is derived from the Old Norse name ''Eiríkr'' (or ''Eríkr'' in Old East Norse due to monophthongization). The first element, ''ei-'' may be derived from the older Proto-Norse ''* aina(z)'', meaning "one, alone, unique", ''as in the form'' ''Æ∆inrikr'' explicitly, but it could also be from ''* aiwa(z)'' "everlasting, eternity", as in the Gothic form ''Euric''. The second element ''- ríkr'' stems either from Proto-Germanic ''* ríks'' "king, ruler" (cf. Gothic ''reiks'') or the therefrom derived ''* ríkijaz'' "kingly, powerful, rich, prince"; from the common Proto-Indo-European root * h₃rḗǵs. The name is thus usually taken to mean "sole ruler, autocrat" or "eternal ruler, ever powerful". ''Eric'' used in the sense of a proper noun meaning "one ruler" may be the origin of ''Eriksgata'', and if so it would have meant "one ruler's journey". The tour was the medieval Swedish king's journey, when newly el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangasius Pangasius
''Pangasius pangasius'', the Pangas catfish, is a species of shark catfish native to fresh and brackish waters of Bangladesh, India, Myanmar, and Pakistan. It has also been introduced to Cambodia and Vietnam. This species grows to a standard length of 60 centimetres, however an aberrant large individual captured in the 1970's grew to a length of .

Vertebra
Each vertebra (: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species. The basic configuration of a vertebra varies; the vertebral body (also ''centrum'') is of bone and bears the load of the vertebral column. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles (pedicle of vertebral arch), two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conduits for the spinal nerves. The body of the vertebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangasius
''Pangasius'' is a genus of medium-large to very large shark catfishes native to fresh water in South and Southeast Asia. The term "pangasius" is sometimes used to specifically refer to the commercially important basa fish, ''P. bocourti''. Taxonomy In 1993, ''Pangasius'' was one of two extant genera (along with ''Helicophagus'') in the family Pangasiidae. At this point, it was split into four subgenera. ''Pangasius'' (''Pangasianodon'') included '' P. gigas'' and '' P. hypophthalmus'' and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single-lobed swimbladder. ''Pangasius'' (''Pteropangasius'') included ''P. micronema'' and ''P. pleurotaenia'' and was typified by four lobes in the swimbladder and with multiple segments in the last lobe. ''Pangasius'' (''Neopangasius'') included ''P. nieuwenhuisii'', ''P. humeralis'', ''P. lithostoma'', ''P. kinabatanganensis'', and typically had palatal teeth arranged in a single larg ...

Catfish Of Asia
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are named for their prominent 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 scale-less, with neither the armour-plated nor the naked species having scales. This order of fish are defined by features of the skull and swimbladder. 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 detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", "polliwogs", or "chuckleheads". These nicknames are not standardized, so one area may call a bullhead catfish by the nic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
