White Bullhead
The white bullhead (''Ameiurus catus''), also known as the white catfish, is a member of the family Ictaluridae of the order Siluriformes. Distribution Originally native to the coastal river systems of the Eastern United States, the catfish spread to other parts of the U.S. Description ''Ameiurus catus '' has a head with eight barbels, two nasal, two maxillary and four chin. It is scaleless. It has a spine on the anterior edge of its dorsal and pectoral fins. It usually has six dorsal soft rays. It does not have palatine teeth. It typically weighs between , however, it is possible to attain weights upwards of 10 pounds (4.5 kg). Habitat ''Ameiurus catus '' is found throughout the U.S. It prefers sluggish, mud-bottom pools and backwaters of rivers and streams, and does well in lakes and large impediments. Behavior Feeding White catfish feed mostly on the bottom, where they eat other fish and aquatic insects. They feed most actively at dusk and through the night ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ictaluridae
The Ictaluridae, sometimes called ictalurids, are a family of catfish native to North America, where they are an important food source and sometimes fished for sport. The family includes about 51 species, some commonly known as bullheads, madtoms, channel catfish, and blue catfish. Taxonomy The family Ictaluridae is strongly supported as a monophyletic group. It is closely related to the Asian family Cranoglanididae. These two families are sister taxa in the superfamily Ictaluroidea. Though the family includes three genera of blind, subterranean, and troglobitic catfishes, ''Trogloglanis'', ''Satan'', and ''Prietella'', none of these three genera is closely related. Instead, ''Satan'' is closely related to ''Pylodictis'', ''Prietella'' to ''Noturus'', and ''Trogloglanis'' possibly to ''Ictalurus'', although it may not be closely related to any of the other ictalurids. ''Ameiurus'' is sister to a clade formed by ''Satan'', ''Pylodictis'', ''Noturus'', and ''Prietella''. Distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Eastern United States
The Eastern United States, commonly referred to as the American East, Eastern America, or simply the East, is the region of the United States to the east of the Mississippi River. In some cases the term may refer to a smaller area or the East Coast plus Illinois, Wisconsin, Indiana, Mississippi, and their border states. In 2011, the 26 states east of the Mississippi (in addition to Washington, D.C. but not including the small portions of Louisiana and Minnesota east of the river) had an estimated population of 179,948,346 or 58.28% of the total U.S. population of 331,745,358 (excluding Puerto Rico). New England New England is a region of the United States located in the northeastern corner of the country, bounded by the Atlantic Ocean, Canada and the state of New York, consisting of the modern states of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut. In one of the earliest English settlements in the New World, English Pilgrims from Europe first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbels
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water. The word "barbel" comes from the Middle Latin ''barbula'', for "little beard." Barbels are sometimes erroneously referred to as '' barbs'', which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth. Barbels may also be nasal, extending from the nostrils. Also, barbels are often mandibular or mental, being located on the chin. In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindrical barbel shapes are buil ...

Bullhead Catfish
''Ameiurus'' is a genus of catfishes in the family Ictaluridae. It contains the three common types of bullhead catfish found in waters of the United States, the black bullhead (''Ameiurus melas''), the brown bullhead (''Ameiurus nebulosus''), and the yellow bullhead (''Ameiurus natalis''), as well as other species, such as the white catfish (''Ameiurus catus'' or ''Ictalurus catus''), which are not typically called "bullheads". The species known as bullheads can be distinguished from channel catfish and blue catfish by their squared tailfins, rather than forked. Taxonomy and fossil record ''Ameiurus'' is recognized as monophyletic, meaning it forms a natural group. It is mostly closely related to the clade formed by the genera '' Noturus'', ''Prietella'', ''Satan'', and ''Pylodictis''. There is a sister group relationship between the species ''A. melas'' and ''A. nebulosus''. Species Extant Species There are currently seven recognized species in this genus: * ''Ameiurus ...

Fish Of The Eastern United States
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. Mos ...

Freshwater Fish Of The Southeastern United States
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wate ...

Taxa Named By Carl Linnaeus
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
