Catfish (order Siluriformes) are a very diverse group of bony fish. Named for their prominent barbels, which give the image of cat-like whiskers, catfish range in size and behavior from the heaviest, the Mekong giant catfish in Southeast Asia and the longest, the wels catfish of Eurasia, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. There are armour-plated types and also naked types, neither having scales. Despite their common name, not all catfish have prominent barbels; what defines a fish as being in the order Siluriformes are in fact certain features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food, and some are exploited for sport fishing, including a kind known as noodling. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby.

Taxonomy

The catfishes are a monophyletic group. This is supported by molecular evidence.^[1] In phylogenetics, a group is monophyletic (Greek: of one race) if it consists of an inferred common ancestor and all its descendants. ...

Catfish belong to a superorder called the Ostariophysi, which also includes the Cypriniformes, Characiformes, Gonorynchiformes and Gymnotiformes, a superorder characterized by the Weberian apparatus. Some place Gymnotiformes as a sub-order of Siluriformes, however this is not as widely accepted. Currently, the Siluriformes are said to be the sister group to the Gymnotiformes, though this has been debated due to more recent molecular evidence.^[2] As of 2007 there are about 36 extant catfish families, and about 3,023 extant species have been described.^[3] This makes the catfish order the second or third most diverse vertebrate order; in fact, 1 out of every 20 vertebrate species is a catfish.^[4] Orders Gonorynchiformes Cypriniformes Characiformes Gymnotiformes Siluriformes Ostariophysi is a superorder of fish. ...

The taxonomy of catfishes is quickly changing. In a 2007 paper, Horabagrus, Phreatobius, and Conorhynchos were not classified under any current catfish families.^[3] There is disagreement on the family status of certain groups; for example, Nelson (2006) lists Auchenoglanididae and Heteropneustidae as separate families, while the All Catfish Species Inventory (ACSI) includes them under other families. Also, FishBase and the Integrated Taxonomic Information System lists Parakysidae as a separate family, while this group is included under Akysidae by both Nelson (2006) and ACSI.^[2][5][6][7] Many sources do not list the recently revised family Anchariidae.^[8] The family Horabagridae, including Horabagrus, Pseudeutropius, and Platytropius, is also not shown by some authors but presented by others as a true group.^[1] Thus, the actual number of families differs between authors. The species count is in constant flux due to taxonomic work as well as description of new species. On the other hand, our understanding of catfishes should increase in the next few years due to work by the ACSI.^[2] Species (Günther, 1864) Pethiyagoda & Kottelat, 1994 Horabagrus is a small genus of catfishes (order Siluriformes). ...

The rate of description of new catfishes is at an all-time high. Between 2003 and 2005, over 100 species have been named, a rate three times faster than that of the past century.^[9] In June, 2005, researchers named the newest family of catfish, Lacantuniidae, only the third new family of fish distinguished in the last 70 years (others being the coelacanth in 1938 and the megamouth shark in 1983).

Relationships between families

The relationship between the families is relatively unknown.^[11] Classifications of superfamilies varies. Many catfish families are classified into their own superfamilies.^[2]

Based on morphological data, Diplomystidae is usually considered to be the most primitive of catfishes and the sister group to the remaining catfishes, grouped in a clade called Siluroidei. Recent molecular evidence contrasts the prevailing hypothesis, where the suborder Loricarioidei are the sister group to all catfishes, including Diplomystidae (Diplomystoidei) and Siluroidei; though they were not able to reject the past hypothesis, the new hypothesis is not unsupported. Siluroidei was found to be monophyletic without Loricarioid families or Diplomystidae with molecular evidence; morphological evidence is unknown that supports Siluroidei without Loricarioidea.^[1] The term morphology in biology refers to the outward appearance (shape, structure, colour, pattern) of an organism or taxon and its component parts. ...

Evolution

A large number of species of catfishes have been named from complete or partial skeletal fossils or even from only otoliths.^[3] 19 valid genera and 72 species are based exclusively on fossil remains.^[3] There are two fossil families, Andinichthyidae, from the Lower Maastrichtian to Paleocene, as well as Hypsidoridae, from the Middle Eocene.^[2] The Maastrichtian is the last stage of the Cretaceous period, and therefore of the Mesozoic era. ...

The earliest known catfish are known from the late Campanian-early Maastrichtian of Argentina.^[13] Catfish fossils are known from every continent except Australia.^[2] Fossils of the Eocene period have been found from Seymour Island in Antarctica.^[4] The order dispersed early throughout the continents primarily through land bridges.^[13] Australian species of catfish are all species from families that can enter saltwater; these fish traveled to Australia through saltwater, and then reverted to a freshwater lifestyle.^{[citation needed]} The Campanian is a stage on the geologic time scale occuring from 83. ... For North Seymour Island in the Galápagos Islands group, see: North Seymour Island. ...

The catfish must have spread through Africa to Asia during the late Jurassic if they were to reach Asia.^[13] During the Cretaceous period, the rift between South America and Africa would be forming; this may explain the contrast in families between the two continents. Most of the freshwater catfish of the two continents appear to be completely unrelated. Their relatively low diversity in Africa may explain why some primitive fish families coexist with them while they are absent in South America, where the more primitive fish may have been driven extinct.^[13] The earliest they could have spread into Central America was the late Miocene.^[13] The Jurassic Period is a major unit of the geologic timescale that extends from about 199. ... The Miocene Epoch is a period of time that extends from about 23. ...

Distribution and habitat

Extant catfish species live in inland or coastal waters of every continent except Antarctica. Catfish have inhabited all continents at one time or another.^[2] Catfish are most diverse in tropical South America, Africa, and Asia.^[4] More than half of all catfish species live in the Americas.

They are found primarily in freshwater environments of all kinds, though most inhabit shallow, running water habitats.^[14] Representatives of a at least eight families are hypogean (live underground) with three families that are also troglobitic (inhabiting caves). Thus, catfishes are some of the most successful cave colonizers among fishes.^[15][16] One such species is Phreatobius cisternarum, known to live underground in phreatic habitats.^[17] Numerous species from the families Ariidae and Plotosidae, and a few species from among the Aspredinidae and Bagridae, are also found in marine environments.^[18][19] Not to be confused with Troglodyte. ...

Ecology

Most catfish are benthic in nature, meaning they normally associate with the bottom of the water column.^[14] However, variety of other lifestyles are also represented among the catfishes. A few species are pelagic in nature.^[14] In marine geology and biology, benthos are the organisms and habitats of the sea floor; in freshwater biology they are the organisms and habitats of the bottoms of lakes, rivers, and creeks. ...

Striped Raphael catfish are able to produce sounds.

Representatives of several catfish families utilize their pectoral spines to produce stridulatory sounds by rubbing a ridged process of the pectoral spine within the cleithral groove, including members of Aspredinidae, Mochokidae, Doradidae, Pimelodidae, and Ictaluridae. Catfishes make a "creaking" sound during defense or appeasement behavior when being attacked by conspecifics.

The unusual insemination method of sperm drinking was first recorded in the bronze corydoras.

In catfishes, fertilization of eggs can be internal, external, or even include sperm passage through female digestive tracts, the so called sperm drinking type of fertilization.^[24] Internal insemination is probable in all species of Auchenipteridae.^[2] Catfishes express varying levels of care reproductive strategies. In loricariids, parental care is usually well-developed and the male guards the eggs and sometimes the larvae, either carrying eggs or having the eggs attached to the underside of rocks or in cavities.^[25] In most of Ariidae, if not all species, the male is a mouthbrooder; he carries the relatively large eggs in his mouth until the young hatch.^[2] Insemination is the introduction of semen into the genital tract of a female. ...

Physical characteristics

External anatomy

Most catfish are adapted for a benthic lifestyle. In general, they are negatively buoyant, which means that they will usually sink rather than float due to a reduced gas bladder and a heavy, bony head.^[14] Catfish have a variety of body shapes, though most have a cylindrical body with a flattened ventrum to allow for benthic feeding.^[14] In physics, buoyancy is the upward force on an object produced by the surrounding fluid (i. ...

The word cylinder has several meanings. ... In sciences dealing with the anatomy of animals, precise anatomical terms of location are necessary for a variety of reasons. ...

A flattened head allows for digging through the substrate as well as perhaps serving as a hydrofoil. Most have a mouth that can expand to a large size and contains no incisiform teeth; catfish generally feed through suction or gulping rather than biting and cutting prey.^[14] However, some families, notably Loricariidae and Astroblepidae, have a suckermouth that allows them to fasten themselves to objects in fast-moving water. Catfish also have a maxilla reduced to a support for barbels; this means that they are unable to protrude their mouths as other fish such as carp.^[14] This article is about marine engineering. ... Incisors (from Latin incidere, to cut) are the first kind of tooth in heterodont mammals. ... Suction is the creation of a partial vacuum, or region of low pressure. ...

The channel catfish has four pairs of barbels.

Catfish may have up to four pairs of barbels: nasal, maxillary (on each side of mouth), and two pairs of chin barbels, although pairs of barbels may be absent, depending on the species. Because their barbels are more important in detecting food, the eyes on catfish are generally small. Like other ostariophysans, they are characterized by the presence of a Weberian apparatus.^[2] Their well-developed Weberian apparatus and reduced gas bladder allow for improved hearing as well as sound production.^[14] Image File history File links Size of this preview: 800 × 600 pixel Image in higher resolution (1024 × 768 pixel, file size: 149 KB, MIME type: image/jpeg) What: Channel Catfish Source: http://www. ...

The armor plates are evident in Corydoras semiaquilus.

Catfish have no scales; their bodies are often naked. In some species, the mucus-covered skin is used in cutaneous respiration, where the fish breathes through its skin.^[14] In some catfish, the skin is covered in bony plates called scutes; some form of body armor has evolved a number of times within the order. In loricarioids and in the Asian genus Sisor, the armor is primarily made up of one or more rows of free dermal plates. Similar plates are found in large specimens of Lithodoras. These plates may be supported by vertebral processes, as in scoloplacids and in Sisor, but the processes never fuse to the plates or form any external armor. By contrast, in the subfamily Doumeinae (family Amphiliidae) and in hoplomyzontines (Aspredinidae), the armor is formed solely by expanded vertebral processes that form plates. Finally, the lateral armor of doradids, Sisor, and hoplomyzontines consists of hypertrophied lateral line ossicles with dorsal and ventral lamina ^{[disambiguation needed]}.^[26] Image File history File linksMetadata Size of this preview: 800 × 540 pixel Image in higher resolution (1600 × 1079 pixel, file size: 252 KB, MIME type: image/jpeg) Photo of Corydoras semiaquilus at the Vancouver Aquarium, taken July 2005 by User:Stan Shebs File links The following pages on the English...

A sting from the striped eel catfish, Plotosus lineatus, may be fatal.

All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bonified leading spine-like ray on their dorsal and pectoral fins. As a defense, these spines may be locked into place so that they stick outwards, which can inflict severe wounds.^[4] In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.^[27] This venom is produced by glandular cells in the epidermal tissue covering the spines.^[2] In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans unfortunate enough to receive a sting; in Plotosus lineatus, the stings may result in death.^[2] Image File history File links Metadata Size of this preview: 800 × 600 pixelsFull resolution (3264 × 2448 pixel, file size: 3. ...

Juvenile catfishes, like most fishes, have relatively large heads, eyes and posterior median fins in comparison to larger, more mature individuals. These juveniles can be readily placed in their families, particularly those with highly derived fin or body shapes; in some cases identification of the genus is possible. As far as known for most catfish, features that are often characteristic of species such as mouth and fin positions, fin shapes, and barbel lengths show little difference between juveniles and adults. For many species, pigmentation pattern is also similar in juveniles and adults. Thus, juvenile catfishes generally resemble and develop smoothly into their adult form without distinct juvenile specializations. Exceptions to this are the ariid catfishes, where the young retain yolk sacs late into juvenile stages, and many pimelodids, which may have elongated barbels and fin filaments or coloration patterns.^[28]

Sexual dimorphism is reported in about half of all families of catfish.^[29] The modification of the anal fin into an intromittent organ (in internal fertilizers) as well as accessory structures of the reproductive apparatus (in both internal and external fertilizers) have been described in species belonging to 11 different families.^[24] Female (left) and male Common Pheasant, illustrating the dramatic difference in both color and size, between the sexes Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species. ...

Internal anatomy

In many catfishes, the humeral process is a bony process extending backward from the pectoral girdle immediately above the base of the pectoral fin. It lies beneath the skin where its outline may be determined by dissecting the skin or probing with a needle.^[31] The pectoral girdle is the set of bones which connect the upper limb to the axial skeleton on each side. ...

The anatomical organization of the testis in catfish is variable among the families of catfish, but the majority of them present fringed testis: Ictaluridae, Claridae, Auchenipteridae, Doradidae, Pimelodidae, and Pseudopimelodidae.^[33] In the testes of some species of Siluriformes, organs and structures such as a spermatogenic cranial region and a secretory caudal region are observed, in addition to the presence of seminal vesicles in the caudal region.^[34] The total number of fringes and their length are different in the caudal and cranial portions between species.^[33] Fringes of the caudal region may present tubules, in which the lumen is filled by secretion and spermatozoa.^[33] Spermatocysts are formed from cytoplasmic extensions of Sertoli cells; the release of spermatozoa is allowed by breaking of the cyst walls.^[33] Look up testes in Wiktionary, the free dictionary. ...

The occurrence of seminal vesicles, in spite of their interspecific variability in size, gross morphology and function, has not been related to the mode of fertilization. They are typically paired, multi-chambered, and connected with the sperm duct, and have been reported to play a glandular and a storage function. Seminal vesicle secretion may include steroids and steroid glucuronides, with hormonal and pheromonal functions, but it appears to be primarily constituted of mucoproteins, acid mucopolysaccharides, and phospolipids.^[24] The seminal vesicles are a pair of simple tubular glands posterinferior to the urinary bladder of males. ...

Catfish as food

Fried catfish fillet served with potatoes and omelette.

Catfish have been widely caught and farmed for food for hundreds of years in Africa, Asia, Europe, and North America. Judgments as to the quality and flavor vary, with some food critics considering catfish as being excellent food, others dismiss them as watery and lacking in flavour.^[35] In Central Europe, catfish were often viewed as a delicacy to be enjoyed on feast days and holidays. To Jews catfish are not Kosher, because the adult fish have no scales. Migrants from Europe and Africa to the United States brought along this tradition, and in the southern United States catfish is an extremely popular food. The most commonly eaten species in the United States are the channel catfish and blue catfish, both of which are common in the wild and increasingly widely farmed. Catfish is eaten in a variety of ways; in Europe it is often cooked in similar ways to carp, but in the United States it is typically crumbed with cornmeal and fried.^[35] In Indonesia catfish is a very popular food. They are usually served grilled in street stalls called warung and eaten with vegetables, the dish is called Pecel Lele (Lele is the Indonesian word for catfish). The iridescent shark is a common food fish in parts of Asia.^{[citation needed]} Vietnamese catfish cannot be legally marketed as catfish in the US, and is subsequently referred to as swai.^[36] Image File history File linksMetadata Size of this preview: 800 × 600 pixelsFull resolution (1600 × 1200 pixel, file size: 954 KB, MIME type: image/jpeg) File links The following pages on the English Wikipedia link to this file (pages on other projects are not listed): Catfish User:Chensiyuan Metadata This file...

Aquaculture

Catfish are easy to farm in warm climates, leading to inexpensive and safe food at local grocers. Ictalurids are cultivated in North America (especially in the Deep South, with Mississippi being the largest domestic catfish producer).^[38] Channel catfish (Ictalurus punctatus) supports a $450 million/yr aquaculture industry.^[4] Catfish raised in inland tanks or channels are considered safe for the environment, since their waste and disease should be contained and not spread to the wild.^[39] The Ictaluridae, sometimes called Ictalurids are catfish native to North America. ...

In Asia, many catfish species are important as food. Several walking catfish (Clariidae) and shark catfish (Pangasiidae) species are heavily cultured in Africa and Asia. Exports of one particular shark catfish species from Vietnam, Pangasius bocourti, has met with pressures from the U.S. catfish industry. In 2003, The United States Congress passed a law preventing the imported fish from being labeled as catfish.^[40] As a result, the Vietnamese exporters of this fish now label their products sold in the U.S. as "basa fish."

Catfish as invasive species

Walking catfish is an invasive species in Florida.

Representatives of the genus Ictalurus have been misguidedly introduced into European waters in the hope of obtaining a sporting and food resource. However, the European stock of American catfishes has not achieved the dimensions of these fishes in their native waters, and have only increased the ecological pressure on native European fauna. Walking catfish have also been introduced in the freshwaters of Florida, with the voracious catfish becoming a major alien pest there. Flathead catfish, Pylodictis olivaris, is also a North American pest on Atlantic slope drainages.^[4] Pterygoplichthys species, released by aquarium fishkeepers, have also established feral populations in many warm waters around the world.^{[41][42][43][44][45]} Image File history File links Clarias_batrachus. ...
