Bullheads do not get as large as the other catfishes native to North America, with average sizes in the one to two-pound range and world record sizes well under . All three major bullheads can be confused with other catfishes by novice anglers. Because they have an unforked tail, many people mistakenly think small flathead catfish are bullheads. Both have the squared tail, and can have a mottled, brown appearance (in the case of the brown bullhead), but the flathead lower lip protrudes farther than its upper lip and it has a flat or "shovel" head.

Reproduction aquarium - here as usually on a wall F. acus is one of the most commonly exported species of Farlowella for the aquarium. Twig catfishes are peaceful and sociable bottom dwellers and can be kept in most freshwater community tanks without problems, either as a single pet or as a group. It thrives best in a tank of at least 24 inches (60 cm) or 35 gallons, and should be provided with plenty of shelter such as bogwood pieces, vine roots, vertical twigs or slender plant stems to allow natural behavior. However, twig catfishes do not handle sudden or large amounts of water changes very well.
However, the lively, fast-moving eye-spot Rasbora is most likely to be compatible with similarly active fishes. Among the species that may be kept in the same aquarium are small characins from South America, assorted small barbs, danios, other small rasboras, Corydoras catfishes, Otocinclus catfishes, the more peaceful dwarf cichlids (and peaceful cichlids such as Laetacara curviceps), and smaller labyrinth fishes. The eye-spot rasbora makes for an interesting 'contrast fish' in company with a shoal of a more brightly coloured species. Furnishing the aquarium for the eyespot rasbora should (as should be the case with all aquarium fish species) be guided principally by the features of its natural habitat.

Kirby Lake is a popular lake for fishing, in particular blue or other catfishes, as well as bluegill. Like most lakes in the region, largemouth bass, carp, white crappie, and other fish also live in the waters. Most people fish directly from the banks rather than using a boat.
Lek-like breeding systems have also been recorded in several other species. In monogamous species, males and females may form pair bonds and breed exclusively with their partners. This occurs in North American freshwater catfishes, many butterflyfishes, sea horses and several other species.Helfman, Collete, Facey and Bowen p.
Fishes of the Minnesota Region. University of Minnesota Press, Minneapolis. It is eaten by many species of fish such as grass pickerel, sunfishes, northern pike, and catfishes; it is also preyed upon by birds, foxes, and snakes when caught out of water.Jenkins, J. R. and Miller, B. A. 2006.

Pseudacanthicus is a genus of medium to large-sized suckermouth armored catfishes native to South America, where found in the Amazon and Orinoco basins, as well as rivers of the Guianas. They are primarily found in fast- flowing waters, sometimes relatively deep. They are sometimes kept in aquariums.
Liobagrus is a genus of catfishes of the family Amblycipitidae. Liobagrus fishes are distributed in the Yangtze River basin, Taiwan, Japan, and the Korea Peninsula. The adipose fin of these fishes is a confluent with the caudal fin. The nostrils are far apart, unlike those found in Amblyceps.
Gogo is a small genus of catfishes (order Siluriformes) of the family Anchariidae. It includes four species. Gogo species are all endemic to freshwater rivers in eastern Madagascar; they are primarily found in highland habitats with clear, swift water. These fish range in size from about in length.
Like most fish, they are able to swim by undulating their bodies; however, they also propel themselves by pumping water through their gill openings to skip along the substrate. Some species are able to produce sounds by moving their pectoral fin spines back and forth when they are agitated. Most aspredinids are generalized omnivores that feed on aquatic and terrestrial invertebrates and organic debris; however, members of Amaralia appear to specialize in feeding on the eggs of other catfishes. A peculiarity of the catfishes in the subfamily Aspredininae is that after the female's eggs are fertilised by the male, she attaches them to her belly and carries them to shallow water to hatch.
The channel catfish is one of only a handful of ostariophysan freshwater fish species whose genomes have been sequenced. The channel catfish reference genome sequence was generated alongside genomic sequence data for other scaled and unscaled fish species (other catfishes, the common pleco and southern striped Raphael; also common carp), in order to provide genomic resources and aid understanding of the evolutionary loss of scales in catfishes. Results from comparative genomics and transcriptomics analyses and experiments involving channel catfish have supported a role for secretory calcium-binding phosphoproteins (SCPP) in scale formation in teleost fishes. In addition to the whole nuclear genome resources above, full mitochondrial genome sequences have been available for channel catfish since 2003.

Catfishes of the genus Akysis are small cryptically-coloured species. Akysis are small secretive fishes that occupy a variety of habitats. Most species typically inhabit clear swift-flowing upland streams with sandy or rocky substrates. Some species are reported from the muddy side and main channels and deltas of large rivers.
A duct forms at the junction between the esophagus and the stomach and expands into an enlarged, ring-like diverticulum, diagnostic of this genus, which allows air-breathing.Armbruster, J.W. (1998): Modifications of the Digestive Tract for Holding Air in Loricariid and Scoloplacid Catfishes. Copeia, 1998 (3): 663–675. Otocinclus are popular aquarium fish.
Pseudobagrus aurantiacus (Temminck and Schlegel) by Kawahara Keiga, 1823 - 1829. Pseudobagrus is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. About half of these species occur in China. The two Coreobagrus species, C. brevicorpus and C. ichikiwai, are both treated in some recent literature as valid in Pseudobagrus.
They are easily distinguished from other catfishes by their strongly depressed head and body and greatly enlarged paired fins that have been modified to form an adhesive apparatus. The flattened shape of these fish and the large pectoral and pelvic fins provide essential adhesion in the fast-flowing waters they live in.
Loricariichthys rostratus is a species of catfishes first found in the Itaipu Dam's reservoir, in the Paraná river.Roberto E. Reis, Edson H. L. Pereira, and S.A. Schaefer (2000) Three New Species of the Loricariid Catfish Genus Loricariichthys(Teleostei: Siluriformes) from Southern South America. Copeia: December 2000, Vol. 2000, No. 4, pp. 1029-1047.
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.
Spatuloricaria is a genus of armored catfishes native to South America and Panama. Spatuloricaria is in need of revision, as species boundaries and distributions are poorly known. The phylogenetic position of Spatuloricaria remains uncertain. Spatuloricaria has been placed at the base of a clade including representatives of the Loricaria and Pseudohemiodon groups.
Dasyloricaria is a genus of armored catfishes native to Central and South America. The distribution of these species includes the northwestern South America on the Pacific slope of Colombia and Panama. Its distribution is restricted to the Pacific slope of the Andes, which is a unique pattern of distribution within the subfamily.
The Malapteruridae are the only group of catfish with well-developed electrogenic organs; however, electroreceptive systems are widespread in catfishes. The electrogenic organ is derived from anterior body musculature and lines the body cavity. Electric catfish do not have dorsal fins or fin spines. They have three pairs of barbels (the nasal pair is absent).
Potamarius is a genus of sea catfishes. The three species in this genus exclusively inhabit fresh water in southern Mexico and Guatemala. The individual species have relatively small ranges. The highly endangered Paragenidens grandoculis of Brazil was long classified in Potamarius, but a 2019 study has found it to belong in its own genus.
Olyra is a genus of catfishes of the family Bagridae. This genus occurs throughout South Asia and western Indochina, from India to western Thailand. In Asia, Olyra species are known as fighting catfish; they are placed in small aquaria to battle one another similar to Siamese fighting fish, and money is bet on the outcome.
Platyclarias machadoi is the only species in the genus Platyclarias of catfishes (order Siluriformes) of the family Clariidae. It originates from the upper Cuango River in Angola. It reaches up to 20.1 centimetres (7.9 in) TL. P. machadoi is easily identified among the clariids due to its extremely flattened head relative to other clariids.
Peckoltia relictum is a species of armored catfish where it is found in the upper Marañon River in northern Peru.Lujan, N.K., Armbruster, J.W., Lovejoy, N. & López-Fernández, H. (2015): Multilocus molecular phylogeny of the suckermouth armored catfishes (Siluriformes: Loricariidae) with a focus on subfamily Hypostominae. Molecular Phylogenetics and Evolution, 62 (Part. A): 269–288.
Austroglanis is the only genus in the catfish family Austroglanididae. This family was split off from the Bagridae catfish family. All three species of catfishes in the family Austroglanididae are endemic to southern Africa (South Africa and Namibia), and two species are threatened. These fish have three pairs of barbels (they lack nasal barbels).
How to avoid fish introductions in Brazil: education and information as alternatives. Natureza & Conservação, in press. Freshwater examples include various cichlids in Florida, goldfish in temperate waters, and South American suckermouth catfishes in warm waters around the world. Invasive species can seriously disrupt their new homes by preying on, or competing with, native species.
Pseudoplatystoma species are all large, boldly striped or spotted catfishes. They are familiar due to their distinctively marked color patterns. They are also recognized due to a depressed head, an occipital process extending backward to contact the predorsal plate, and a very long fontanel. After gonadal maturation, females tend to grow faster than males.
Of the 29 Noturus species, more than 50% are considered vulnerable, imperiled, or extinct, and many are likely in need of conservation action due to small ranges and increasing anthropogenic threats,Burr, B.M., and J.N. Stoeckel. 1999. The natural history of madtoms (genus Noturus). North America’s diminutive catfishes. American Fisheries Society Symosium 24:51-101.
The fish rotates its lower and upper jaws to scrape the substrate. Of the two, the lower jaws are more mobile. Loricariid catfishes have evolved several modifications of their digestive tracts that function as accessory respiratory organs or hydrostatic organs. These complex structures would have been independently evolved a number of times within the family.
Aspredinichthys is a genus of banjo catfishes found in fresh and brackish waters in tropical South America from the Orinoco delta, through the Guianas, to the Amazon delta. Both species are found in lower portions of rivers and in coastal waters of northern South America from Venezuela to northern Brazil where they are benthic fish.
The Arkansas River is continuously turbid. Summer flow in smaller streams is typically limited or nonexistent. Fish communities characteristically contain a substantial proportion of sensitive species; a sunfish- and minnowdominated community exists along with substantial proportions of darters and catfishes (particularly madtoms). The Arkansas Valley ecoregion has been subdivided into five Level IV ecoregions.
Electric catfish or Malapteruridae is a family of catfishes (order Siluriformes). This family includes two genera, Malapterurus and Paradoxoglanis, with 21 species. Several species of this family have the ability to produce an electric shock of up to 350 volts using electroplaques of an electric organ. Electric catfish are found in tropical Africa and the Nile River.

The vertebrate fossils in the Florissant are predominantly small fragments of incomplete bones. There have been a few described species of vertebrates, mostly fish, but also birds and mammals. The fish discovered at the site include bowfins, suckers, catfishes, and pirate perches. Most of these were bottom dwellers, except the perches, and many were tolerant of poor water conditions.
Pseudolaguvia is a genus of South Asian river catfishes. These species inhabit hill streams and large rivers. P. tenebricosa is found in fast running, clear water; the river has a sandy bottom and numerous rocks and boulders and aquatic vegetation is absent. P. inornata is from clear, shallow, moderately flowing streams with a predominantly sandy bottom.
Pareutropius debauwi is a species of fish in the Schilbeidae, the schilbid catfishes. Its common name is African glass catfish.

It is widespread and faces no serious threats.
Loricariichthys edentatus is a species of catfishes found in Entre Rios Province, Argentina. It has no teeth on the premaxilla, a unique feature in the genus Loricariichthys.Roberto E. Reis, Edson H. L. Pereira, and S.A. Schaefer (2000) Three New Species of the Loricariid Catfish Genus Loricariichthys(Teleostei: Siluriformes) from Southern South America. Copeia: December 2000, Vol.
The palate is toothless except in the fossil genus Astephus. The genera Trogoglanis, Satan, and Prietella include four species of blind catfishes. They have the ability to inflict painful stings with venomous spines embedded in their fins. One of the largest species is the blue catfish, Ictalurus furcatus, specimens of which have been found to weigh over .
Neoerethistes is a genus of true weevils in the beetle family Curculionidae. There are more than 30 described species in Neoerethistes. The only species in North American north of Mexico is Neoerethistes arizonicus, found in the southwestern United States. The genus Neoerethistes was formerly called Erethistes, which is the name of a genus of South Asian river catfishes.
Microsynodontis is a genus of upside-down catfishes native to freshwater rivers in western Africa. The genus was originally described by British- Belgian zoologist George Albert Boulenger in 1903 based upon the type species Microsynodontis batesii. The name microsynodontis comes from the Greek word mikro, meaning small, and the Greek term synodon, meaning "with the teeth all growing together".
Phractura is a genus of loach catfishes (order Siluriformes) that occur in Africa. Phractura species are elongated fish with a long caudal peduncle and bony scutes on the sides, back, and belly., this feature giving the genus its name from the Greek phraktos, which means enclosed and oura which means tail.Phractura species are often associated with vegetation.
Venom is found in some 200 cartilaginous fishes, including stingrays, sharks, and chimaeras; the catfishes (about 1000 venomous species); and 11 clades of spiny-rayed fishes (Acanthomorpha), containing the scorpionfishes (over 300 species), stonefishes (over 80 species), gurnard perches, blennies, rabbitfishes, surgeonfishes, some velvetfishes, some toadfishes, coral crouchers, red velvetfishes, scats, rockfishes, deepwater scorpionfishes, waspfishes, weevers, and stargazers.
Cathorops is a genus of catfishes in the family Ariidae found in the Atlantic and Pacific Oceans. These species are found in the eastern and western Central and South America in brackish and freshwater habitats.Marceniuk, A.P. & Menezes, N.A. (2007): Systematics of the family Ariidae (Ostariophysi, Siluriformes), with a redefinition of the genera. Zootaxa, 1416: 1–126.
Synodontis is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. Synodontis has over 131 different species within the genera. Synodontis are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed.
Akysis longifilis is a species of catfish belonging to the family Akysidae, the stream catfishes. It is only known to inhabit the Sittang River basin in southern Myanmar. As a small catfish, it is up to standard length, with a dark brown body marked with yellowish saddle-shaped markings, very long barbels, and a forked caudal fin.
Amphiliids are generally small catfishes with tapering, elongated bodies. The pectoral and ventral fins are large, and the first ray of each is usually broad, flexible, and filamentous. The eyes are generally small and located in the upper part of the head. The gas bladder is reduced and divided into two lobes surrounded by bony capsules.
These catfishes have three pairs of barbels (nasal barbels are absent). The dorsal and pectoral spines are absent, or weakly developed (as in Leptoglanidinae and Trachyglanis). They reach at a maximum, but most species do not exceed in length. The small mouth is located on the underside of the head, and has thick lips bearing several soft lumps (papillae).
Ancistrus claro is a species of armored catfish endemic to Brazil where it is found in the Cuiabá River basin. This species grows to a length of SL.Fisch- Muller, S., 2003.

Scleronema is a genus of pencil catfishes native to South America. They are a member of the subfamily Trichomycterinae. Species of Scleronema are geographically distributed in the La Plata basin and Atlantic coastal drainages from Southern Brazil, Southern Paraguay, Northeastern Argentina and Uruguay. They inhabit rivers or streams with sand or gravel-bottoms across the Pampa grasslands.
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.
The Stegophilinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes 12 genera: Acanthopoma, Apomatoceros, Haemomaster, Henonemus, Homodiaetus, Megalocentor, Ochmacanthus, Parastegophilus, Pareiodon, Pseudostegophilus, Schultzichthys, and Stegophilus. A monophyletic group within the Stegophilinae is supported by two characteristics of the lateral line, including Acanthopoma, Henonemus, Megalocentor, Pareiodon, Parastegophilus, and Pseudostegophilus. Acanthopoma and Henonemus have a sister group relationship.
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.Chakrabarty, P. & Ng, H.H. (2005): The identity of catfishes identified as Mystus cavasius (Hamilton, 1822) (Teleostei: Bagridae), with a description of a new species from Myanmar. Zootaxa, 1093: 1–24.
Heterobranchus is a genus of airbreathing catfishes native to Africa. However, H. palaeindicus, the only known extinct species of the genus, was discovered in the Siwalik Hills, India, dating to the Lower Pliocene. Depending on the exact species involved, fish of this genus reach from with H. longifilis being the largest strict freshwater fish in southern Africa, reaching SL and weighing up to .
In southern Mississippi, evidence was found of freckled madtoms feeding on the smaller speckled madtom (N. leptacanthus). To aid in devouring victims, this catfish has a venom glands along smooth spines on the pectoral and dorsal fins.Egge, J.J.D. and Simons, A.M., "Evolution of Venom Delivery Structures in Madtom Catfishes (Siluriformes: Ictaluridae)." Biological Journal of the Linnean Society 102 (2011): 115-129.
Striped eel catfish, Plotosus lineatus The eeltail catfish are a family (Plotosidae) of catfish whose tails are elongated in an eel-like fashion. These catfishes are native to the Indian Ocean and western Pacific from Japan to Australia and Fiji. The family includes about 41 species in 10 genera. About half of the species are freshwater, occurring in Australia and New Guinea.
Pseudoplatystoma is a monophyletic assemblage of catfishes. P. fasciatum was the first species to be described, under the name Siluris fasciatus. In 1829, P. corruscans was described under the name Platystoma corruscans, and over a decade later, P. tigrinum was described as Platystoma tigrinum. In 1862, Pseudoplatystoma was described and these species transferred to it, with P. fasciatum as type species.
Blindfish do, however, have rows of sensory papillae on their skin, which they use to help navigate. Similar darkness-adaptive traits can be seen in many fish families where members live underground and is known as convergent evolution.Rantin B., and M.E. Bichuette (2013). Phototactic behaviour of subterranean Copionodontinae Pinna, 1992 catfishes (Siluriformes, Trichomycteridae) from Chapada Diamantina, central Bahia, northeastern Brazil.
The Mochokidae are a family of catfishes (order Siluriformes) that are known as the squeakers and upside-down catfish (although not all species swim upside-down). There are nine genera and about 200 species of mochokids. All the mochokids are freshwater species originating from Africa. They have three pairs of barbels, with the nasal barbels absent; sometimes, the mandibular barbels may be branched.

This family includes species previously placed in Sisoridae. They were removed because they were thought to be more closely related to the neotropical Aspredinidae than to the remaining sisorids due to a number of morphological characters. However, it has been suggested that the erethistid catfishes be included back into Sisoridae and some genera are included in that family by some authorities.

Yellowfin madtom are found in backwaters and pools around rocks less than 30 cm in diameter and tree roots in clear creeks and small rivers.Bauer B.H., G. Dinkins and D. Etnier.1983.
To attract mates, some teleosts produce sounds, either by stridulation or by vibrating the swim bladder. In the Sciaenidae, the muscles that attached to the swim blabber cause it to oscillate rapidly, creating drumming sounds. Marine catfishes, sea horses and grunts stridulate by rubbing together skeletal parts, teeth or spines. In these fish, the swim bladder may act as a resonator.
Ernstichthys is a genus of banjo catfishes that occurs in the Amazon and Orinoco basins. Ernstichthys species are small to medium-sized, armored aspredinids. Members of this genus are distinguished from all other aspredinids by having two sets of paired pre-anal-fin plates and a strongly recurved pectoral spine that is much longer than first branched pectoral-fin ray.

Siluridae is the nominate family of catfishes in the order Siluriformes. About 105 living species of silurids are placed in 14 genera. Although silurids occur across much of Europe and Asia, they are most diverse in Southeast Asia, beyond which their diversity decreases in temperate East Asia, the Indian subcontinent, Southwest Asia, and Europe. Silurids are apparently absent from much of central Asia.
The spiny dogfish (pictured) is a known prey item of the bramble shark. Bramble shark embryo with external yolk sac. Sluggish in nature, the bramble shark feeds on smaller sharks (including the spiny dogfish, Squalus acanthias), bony fishes (including ling, catfishes, and lizardfishes), and crabs. The large size of its pharynx, relative to its mouth, suggests that it may capture prey by suction.
Arius manillensis was first described by the French zoologist Achille Valenciennes in 1840. It belongs to the genus Arius of the subfamily Ariinae, family Ariidae (ariid or fork-tailed catfishes). It should not be confused with the closely related Cephalocassis manillensis, also described by Valenciennes in 1840. Other common names of the species include kandule, dupit, kiti-kiti, tabangongo, and tauti.

The mangroves near Rio Tavares are also used as shelters for several seabirds species and migratory birds.
Madtoms are freshwater catfishes (order Siluriformes) of the genus Noturus of the family Ictaluridae. It is the most species-rich family of catfish in North America, native to the central and eastern United States, and adjacent parts of Canada. Their fin spines contain a mild venom with a sting comparable to that of a honey bee.Florida Museum of Natural History: Ictaluridae Retrieved 6 April 2014.
The latter two genera are more specialized for this lifestyle than any other catfishes, as evidenced by their loss of morphological traits. These two species also have paired keels, called metapleural keels, formed by long ridges of stiffened integument, extend along the entire ventral margin of the abdomen, ending posteriorly shortly posterior to the anus. These keels probably serve to stabilize the body while moving in sand.
The Hypoptopomatinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae, composed of 17 genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species. It has been divided into two tribes, Hypoptopomatini and Otothyrini. However, in a 2005 analysis, Otothyrini was found to not be monophyletic, with its representatives comprising a paraphyletic group in relation to the tribe Hypoptopomatini.
To the Northwest, its range extends beyond Pakistan into Iran and Afghanistan. To the East, it can be found as far as the Irrawaddy river basin in Myanmar.Babare R. S., Chavan S.P., Kannewad P. M. (2013): Gut Content Analysis of Wallago attu and Mystus (Sperata) seenghala, the common Catfishes from Godavari River System in Maharastra State. Advances in Bioresearch, 4 (2): pg. 123-128.
Acanthicus is a genus of large, South American suckermouth armored catfishes native to the Amazon and Orinoco basins, and possibly in Guyana. The name Acanthicus is derived from the Greek, akanthikos meaning thorny, spiny. Fish of this genus are known as lyre-tail plecos. These species are found in large rivers, primarily in areas with a rocky bottom and a moderate or strong current.
Chemical alarm systems have been identified in a number of different taxa, including gastropods,(Stenzler and Atema 1997; Atema and Stenzler 1977) echinoderms,(Snyder and Snyder 1970) amphibians(Hews and Blaustein 1985; Hews 1998; Lutterschmidt et al. 1994) and fishes. One of the most well-studied chemical alarm signals is schreckstoff, the use of which is widespread in the superorder Ostariophysi (e.g., minnows, characins, catfishes, etc.).
Ailiidae is a family of catfishes native to Asia.Wang, J., Lu, B., Zan, R., Chai, J., Ma, W., Jin, W., Duan, R., Luo, J., Murphy, R.W., Xiao, H. & Chen, Z. (2016): Phylogenetic Relationships of Five Asian Schilbid Genera Including Clupisoma (Siluriformes: Schilbeidae). PLoS ONE, 11 (1): e0145675. These fishes usually have dorsal fins with a short base and a spine, but Ailia lack a dorsal fin altogether.
From 1997-2001, 361,022 hardhead catfish were harvested within 200 miles of the shore in the IRL region. Hardheads are also harvested for industrial purposes in commercial bottom-trawling operations. Annual harvests vary greatly, but from 1987–2001, 1.04 million pounds of marine catfishes (including both the hardhead catfish and the gafftopsail catfish) were harvested in the IRL region. The harvest was valued at $777,497.
Docimodus evelynae is a species of haplochromine cichlid. It is endemic to Lake Malawi; it is widespread in the lake and found in Malawi, Mozambique, and Tanzania. This species has unusual feeding habits: it feeds upon the flank scales of cichlids or cyprinids and the skin of catfishes. The specific name honours Evelyn Axelrod, the wife of the publisher Herbert R. Axelrod (1927-2017).
Aphanotorulus is a genus of armored catfishes native to the Amazon, Orinoco, Essequibo and Jaguaribe basins in South America.Ray, C.K. & Armbruster, J.W. (2016): The genera Isorineloricaria and Aphanotorulus (Siluriformes: Loricariidae) with description of a new species. Zootaxa, 4072 (5): 501–539. They typically occur on a sand or gravel bottom in slow to moderately flowing rivers and streams, but some species occur in areas with fast current.
The North American channel catfish is an ostariophysan, or a bony fish occupying a freshwater habitat. These fishes are known to produce club cells and alarm substances for communication purposes. Both the fish's habitat and the presence of chemosensory cells covering the body are presumably the results of favored selection for this method of communication. Catfishes are capable of producing and recognizing individual specific pheromones.
Pareuchiloglanis is a genus of sisorid catfishes native to Asia. These species are rheophilic catfish chiefly found in the headwaters of major rivers in South and East Asia. They originate from the Brahmaputra drainage in India, east and south to the Yangtze drainage in China and the Annamese Cordillera drainages in southern Vietnam. Two species are known from the Mekong River: P. myzostoma and P. gracilicaudata.
Arius is a genus of catfishes (order Siluriformes) of the family Ariidae. The genus Arius is distributed in brackish and fresh waters of Eastern Africa and south to Southeast Asia. Defining the limits so that Arius can form a natural grouping has always been a problem. The genus was never properly defined, and many species previously classified in Arius are now in other genera.
Platyallabes tihoni is the only species in the genus Platyallabes of catfishes (order Siluriformes) of the family Clariidae. This species is found in the Malebo Pool. P. tihoni has a body plan that is intermediate to the generalized, fusiform (torpedo-shaped) type such as Clarias species and the anguilliform (eel-shaped) type such as Gymnallabes. This species is known to grow up to 52.8 centimetres (20.8 in) TL.
The species can reach a total length of .Roberts, T.R. (2014): Wallago Bleeker, 1851 and Wallagonia Myers, 1938 (Ostariophysi, Siluridae), Distinct Genera of Tropical Asian Catfishes, with Description of †Wallago maemohensis from the Miocene of Thailand. Bulletin of the Peabody Museum of Natural History, 55 (1): 35-47. It shares parts of its native range with the externally similar, but much larger Wallagonia leerii, and is subsequently often confused for it.
Olivaichthys is a genus of velvet catfishes endemic to Argentina. Recently several authors have synonymized this genus with Diplomystes. A molecular analysis has proposed that trans-Andean Diplomystes and the cis-Andean Olivaichthys are so closely related (in addition to the close morphological similarity), that Olivaichthys should not be recognized. However, this is strange as recent divergence is unlikely with the species on either side of the Andes.
Dr. Reis is an author of over 120 original journal papers, 14 book chapters, and four books. Dr. Reis is Chief Editor of the Checklist of Freshwater Fishes from Central and South America (CLOFFSCA), and past President of the Brazilian Ichthyological Society. Dr. Reis is an authority on the systematics and biodiversity of Neotropical catfishes and has to date with colleagues discovered and described oven 100 fish genera and species.
Doumea is a genus of loach catfishes native to Africa. Species of Doumea have a rather large and tapered body, a pointed head, and a thin caudal peduncle. Thin bilateral osseous peaks are sometimes present on the back and the belly, and are the precursors series of osseous plates observed in the other kinds of Doumeinae. By the shape of the body, these fish are adapted to rapids.
Dupouyichthys sapito is the only species of banjo catfishes in the genus Dupouyichthys. This species appears to be restricted to the Magdalena and Maracaibo basins. D. sapito is a small, armored aspredinid, growing up to 27 millimetres (1.1 in) SL, distinguished from all other aspredinids by having only one set of paired pre-anal-fin plates. Also, the bony ornamentation of its skull is better developed than its close relatives.
Virtually nothing is known of the natural history of T. marauna, including the function of its unique jaw extensions and extra teeth. These structures are found in both sexes, suggesting that they are not involved in reproductive behaviors as in other knifefishes with accessory teeth (e.g. Sternarchogiton nattereri). An alternate possibility is that they are used in feeding; similar structures in the stegophiline catfishes are used to gather mucus and scales.
Pseudomystus species are small- to mid- sized bagrid catfishes. Many Pseudomystus species are beautiful fishes with colour patterns of striking contrast, with light bands and/or blotches on a dark background on the body and fins, with the pattern reversed on some fins in some species. This coloration leads them to be known as bumblebee catfish in the aquarium trade. Some species were described to have a uniform colour have a banded colouration when juvenile.
Pterygoplichthyini is a tribe of catfishes (order Siluriformes) of the family Loricariidae. It includes two genera, Pterygoplichthys and the currently undescribed genus referred to as the Hemiancistrus annectens group, This group was earlier misspelled as Pterygoplichthini. Pterygoplichthyines are known from nearly the entire range of loricariids except for the Guyanas and coastal streams in southeastern Brazil. although later work by the same authority, and his co-authors, placed this group among the genus Hypostomus.
It is mainly piscivorous once it reaches 13–34 cm in length. Schilbe intermedius rarely grows to lengths greater than 30 cm. It breeds throughout the year peaking in the rainy season when it migrates into rivers in fairly compact schools to spawn in floodwater pools. In one study the most common prey item was redeye barb, a cyprinid, which made up 29% of all identifiable fish species sampled from the catfishes stomachs.
Pseudobagarius meridionalis is a species of catfish belonging to the family Akysidae (the stream catfishes). It is only known from the Barito River basin in southern Borneo. This is a very small catfish, up to 32 mm standard length, with a body dark brown above with a few scattered pale spots and white below, with a strongly projected upper jaw so that the premaxillary teeth are clearly visible even when the mouth is closed.
During courtship behavior in three species of Corydoras catfishes, all males actively produced stridulation sounds before egg fertilization, and the species' songs were different in pulse number and sound duration. Sound production in catfish may also be correlated with fighting and alarm calls. According to a study by Kaatz, sounds for disturbance (e.g. alarm) and agonistic behavior were not significantly different, which suggests distress sounds can be used to sample variation in agonistic sound production.

Lophiosilurus alexandri (a flattened catfish), Franciscodoras marmoratus (an armoured catfish), Pygocentrus piraya (the largest species of piranha), Orthospinus franciscensis (a characin and the only member of its genus), Hasemania nana (a small tetra that often is kept in aquariums), and Salminus franciscanus (a relative of the golden dorado).Lima, F. C. T., and H. A. Britski (2007).
Among the elopomorphs, eels have elongated bodies with lost pelvic girdles and ribs and fused elements in the upper jaw. The 200 species of osteoglossomorphs are defined by a bony element in the tongue. This element has a basibranchial behind it, and both structures have large teeth which are paired with the teeth on the parasphenoid in the roof of the mouth. The clade Otocephala includes the Clupeiformes (herrings) and Ostariophysi (carps, catfishes and allies).
In addition to mouthbrooding, some teleost have also developed structures to carry young. Male nurseryfish have a bony hook on their foreheads to carry fertilised eggs; they remain on the hook until they hatch. For seahorses, the male has a brooding pouch where the female deposits the fertilised eggs and they remain there until they become free-swimming juveniles. Female banjo catfishes have structures on their belly to which the eggs attach.
Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, 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 cascudos or acarís.
Striped Raphael catfish in an aquarium. The striped Raphael catfish is a fine and sociable community fish that are peaceful to fellow catfishes and other fish species. However, they are nocturnal, and are usually not visible during the day. It is best not to catch the striped Raphael catfish with a fish net because they are prone to sticking out their pectoral fin spines in a very rigid manner, especially if stressed.
Congoglanis is a genus of loach catfishes found in the Congo River system of Africa. This genus is considered the sister group of all other species in the subfamily Doumeinae.Ferraris, C.J. Jr., Vari, R.P. & Skelton, P.H. (2011): A new genus of African loach catfish (Siluriformes: Amphiliidae) from the Congo River basin, the sister-group to all other genera of the Doumeinae, with the description of two new species. Copeia, 2011: 477–489.
Tete sea catfishes are occasionally available in the pet trade under a variety of names, including Colombian (or Columbian) shark, silver tipped shark, white tip shark catfish, black fin shark, Christian catfish, Jordan's catfish, and West American cat shark. However, they are not appropriate for most aquarists because they must be acclimated from freshwater to saltwater as they mature. It requires a very large tank due to its size and active swimming habits.Columbian Shark. FishLore.com.
Most electrogenic fish are also electroreceptive. Electric fish species can be found both in the ocean and in freshwater rivers of South America (Gymnotiformes) and Africa (Mormyridae). Many fish such as sharks, rays and catfishes can detect electric fields and are thus electroreceptive, but they are not classified as electric fish because they cannot generate electricity. Most common bony fish (teleosts), including most fish kept in aquaria or caught for food, are neither electrogenic nor electroreceptive.
The Trichomycterinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes six genera, Bullockia, Hatcheria, Rhizosomichthys, and Eremophilus, all monotypic, Silvinichthys with two species, and Trichomycterus, with over 100 species. The former five genera are diagnosed by putatively apomorphic characters, whereas Trichomycterus is defined by the lack of those specializations and is likely not monophyletic. This subfamily has historically served as much of a wastebasket for trichomycterids that lack the specializations of the other subfamilies.
The genus Panaque contains a small number of small to medium-sized South American suckermouth armoured catfishes that are notable for being among the very few vertebrates that feed extensively on wood. In addition, algae and aufwuchs are an important part of the diet, and they use their rasping teeth to scrape this from rocks. These fish are also popular aquarium fish, where the sound of scraping as these fish forage for food is easily audible.
Paradise fish tankmates must be chosen with care. Suitable ones include giant danios, large tetras, most smaller catfishes, and even some of the less aggressive cichlids, such as firemouth cichlids. Slow-moving or long-finned fish such as fancy goldfish and freshwater angelfish are likely to be attacked by males; bettas and gouramis may also be victimized due to their resemblance to paradise fish. Male paradise fish may also attempt to court female bettas and gouramis.
Auchenoglanis is a genus of relatively large, up to SL, claroteid catfishes native to various freshwater habitats in Africa. Auchenoglanis is a primitive member of the subfamily Auchenoglanidinae (also includes Notoglanidium and Parauchenoglanis) and represents a stem group. Species of this genus occur predominantly in the Nilo-Sudan region and Western Africa, but also in the Congo River, Lakes Albert and Tanganyika. Auchenoglanis species mainly feed on insect aquatic larvae and eventually on small mollusks, alevin, and swimming insects.
Han Nijssen (1935– 2013)H. Nijssen, 1935 - at the UvA Album academicumObituary in the Nederlandse commissie record zeevissen (Ncrz) annual report for 2013 was a Dutch ichthyologist.DEPARTMENT of ICHTHYOLOGY California Academy of Sciences, Newsletter of Systematic Ichthyology Number Twenty-Two Nijssen was born in Amsterdam and obtained his PhD at the University of Amsterdam in May 1970 with the dissertation Revision of the Surinam catfishes of the genus Corydoras. Later he was a curator at Zoölogisch Museum in Amsterdam.
For sea catfishes, cardinalfishes, jawfishes and some others, the egg may be incubated or carried in the mouth, a practice known as mouthbrooding. In some African cichlids, the eggs may be fertilised there. In species like the banded acara, young are brooded after they hatch and this may be done by both parents. The timing of the release of young varies between species; some mouthbrooders release new- hatched young while other may keep then until they are juveniles.
Given many historians the river Koysuv on which aul Kostek is situated was abundant in fish. J. Güldenstädt in the end of the 18th century wrote that not only sturgeons, starred sturgeons, catfishes, carps and asps harboured there. But he noted that there were no salmons which were in Terek river. But some time later in the beginning of the 19th century Semyon Bronevskiy in his description of river Koysuv mentioned salmons and Kizlyar herring (shamaya).
Environmental Biology of Fishes. 10:215-219. This species is also known to feed in the winter in temperatures as low as 1.1 °C. According to Jenkins and Miller, some animals that feed on the mudminnow are the grass pickerel, sunfishes, northern pike, and catfishes; it is also preyed upon by birds, foxes, and snakes when caught out of water. This mudminnow is known to bury itself in the mud or sand to avoid capture in some situations.
The Andean catfish's natural habitats are the mountainous rivers, freshwater springs or aquifers, caves and inland karsts of four different drainage basins within the Imbakucha watershed. It is brownish gray in colour and has no scales; large adults can grow up to 150 mm. Like all other catfishes, it has barbels around the mouth which contain taste buds that help the animal find food at night. Its diet consists of other fish, frogs, snails, algae, and other aquatic organisms.
Pareiorhina is a genus of armored catfishes native to South America where they are only found in Brazil. These species are known to occur at altitudes above 650 metres (2100 ft) in various rivers of the Grande, Paraíba do Sul, São Francisco and Tietê River basins. This genus was first erected by Gosline in 1947 as a monotypic genus to include Rhinelepis rudolphi. It was not until 2003 that a second species, P. carrancas, was described.
Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of northeast India, and east and south to the Salween drainages in Burma. E. berdmorei is found in the Sittang and Salween drainages in Burma. E. labiatum is known from the Brahmaputra drainage in northeast India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma.
Hisonotus is a genus of armored catfishes native to South America. Species of Hisonotus and Curculionichthys are the only representatives of the subfamily Otothyrinae having serrae on the posterior edge of the pectoral fin spine. These species are small fishes, generally found in small fast flowing streams, where they grasp to the branches and leaves of aquatic or subaquatic plants. The species of this genus mostly occur in Atlantic coastal streams of southern Brazil and the Paraguay-Paraná system of southern South America.
The waters of Uganda contain an impressive array of fish species—over 90 in all. This count does not include the Haplochromis complex, which itself is made up of more than 200 species. Fish that are the target of most commercial and subsistence exploitation include species of Lates (Nile perch), Oreochromis (Nile tilapia), the herring-like Alestes, the catfishes Bagrus and Clarias, Hydrocynus (Tiger fish), the small pelagic “sardine” Rastrineobola, Protopterus (lungfish), and the haplochromines."Review of Fish Marketing in Uganda" fao.org.
Bagrichthys catfishes are highly specialized. Fish of this genus are characterised by their elongate and laterally compressed caudal peduncle, the dorsally-directed serrations on the posterior edge of the dorsal fin spine, gill membranes united at the isthmus, and a long adipose fin without a free posterior margin. These fish can grow between about 20-40 centimetres (8-16 in) in length. The coloration of Bagrichthys species varies from tan to black; however, coloration can vary between individuals based on environmental conditions.
Glyptothorax is a genus of catfishes order Siluriformes of the family Sisoridae. It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor (in the Tigris and Euphrates River drainages) and southwards to Southeast Asia.
Paragenidens is a monotypic genus of sea catfishes containing just one species, Paragenidens grandoculis. This species was formerly classified under the genus Potamarius until a 2019 study found it to be wholly distinct from it. It is endemic to Brazil, where it is known from the Doce and the Paraíba do Sul rivers and their mouths. It is highly endangered and was not seen for over 50 years until it was rediscovered during fieldwork for the 2019 study that reclassified it.
Both A. adonis and A. hystrix are sometimes kept in aquariums, and especially the densely white-spotted juveniles of the former species are regularly seen in the trade. They are opportunistic, omnivorous feeders that require well-oxygenated water. Their massive adult size and territorially aggressive behavior means that a very large tank is required. The territorial behavior is mostly aimed at other suckermouth armored catfishes and during disputes Acanthicus have even been known to kill Pterygoplichthys gibbiceps (itself typically considered a robust species).
Walking catfish is an invasive species in Florida. Representatives of the genus Ictalurus have been 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 fish 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.
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. Sexual dimorphism is reported in about half of all families of catfish. 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.
The movement is analogous to a finger moving down the teeth of a comb, and consequently a series of sharp taps is produced. Sound-generating mechanisms are often different between genders. In some catfishes, pectoral fins are longer in males than in females of similar length, and differences in the characteristic of the sounds produced were also observed. Comparison between families of the same order of catfish demonstrated family and species-specific patterns of vocalization, according to a study by Maria Clara Amorim.
Docimodus johnstoni is a species of haplochromine cichlid. It is known from Lake Malawi, Lake Malombe, and the upper Shire River in Malawi, Mozambique, and Tanzania. This species has unusual feeding habits: it is reported to feed on fins of clariid catfishes. The specific name honours the British explorer, botanist, linguist and Colonial administrator, Sir Henry Hamilton Johnston (also known as Sir Harry Johnston) (12 June 1858 – 31 July 1927), who presented the type to the British Museum (Natural History).
The family Cetopsidae includes species of small- to medium- sized catfishes which share an anal fin with a long base, the lack of nasal barbels, and, usually, a lack of dorsal and pectoral fin spines. In Cetopsinae, the swim bladder is highly reduced and is enclosed in a bony capsule. Cetopsines lack an adipose fin, while it may be present (though small) in Helogeneinae. Many species are characterized by small eyes obscured by a thick, overlying integument that make them appear blind.
Aspredinids live in a variety of habitats ranging from shallow backwaters to deep river channels to tidal estuaries. Some aspredinids appear to be semifossorial, during the day often resting slightly buried in leaf litter or other soft substrates. Members of the subfamily Aspredininae inhabit coastal rivers and brackish water habitats such as mangrove swamps.Sands D.: South American Catfishes, Interpet 1988, Monks N. (editor): Brackish Water Fishes, TFH 2006, In general, most species are cryptically pigmented, benthic, and rather sluggish unless disturbed.
A few banjo catfishes are kept as aquarium fish, predominantly the smaller members of the subfamily Aspredininae. Their requirements are similar to those of other tropical South American fish, preferring slightly acidic, not too hard water maintained at 20-25 °C (68-77 °F). Since these species are nocturnal burrowers, they need an aquarium with a soft, sandy substrate into which they hide during the daytime and forage in at night. Sharp sand or coarse gravel will damage their whiskers.
This species' native range is tropical northeastern South America; it naturally occurs in northeastern Brazil, the Guianas, and Trinidad and Tobago. Confusingly, the name Hypostomus plecostomus (or Plecostomus plecostomus) has sometimes been incorrectly used for several more-or-less similar loricariid catfishes, both in the popular and scientific literature. For example, it has sometimes been suggested that it occurs in southern Central America, but this is an entirely separate species, Hemiancistrus aspidolepis (also known under another synonym, Hypostomus panamensis).Bussing, W.A. (1998).
Paracanthopoma parva is a species of catfishes (order Siluriformes) of the family Trichomycteridae. P. parva grows to about 2.7 centimetres (1.1 in) SL and is endemic to Brazil where it occurs in the Amazon and Essequibo River basins. Paracanthopoma parva has been found on the gills of another species of giant catfish, Brachyplatystoma vaillanti. Species within the genus Paracanthopoma have the longest and most robust snout, and the longest and strongest dentary teeth among blood-feeding candirus, which fit their drilling needs.
Mannix attempts to blackmail David by threatening to reveal that he stole medication from the hospital to help him, but David goes to the hospital board himself. After Paul tells him David went to the police, Mannix leaves town. To get back at Paul, Mannix catfishes his friend Jane Harris and cons her out of her savings. Paul learns Mannix is behind the con and tells him to pay back the money, but Mannix tells him that he has already spent it on a car.
It has been noted that Pelteobagrus may not be monophyletic if species placed in Pseudobagrus and Coreobagrus were excluded. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of Tachysurus. Pseudobagrus species are small- to mid-sized bagrid catfishes. These fish all have an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin in most species; two dorsal fin spines; pelvic fin small; and caudal fin emarginate, truncate or round.
The Hypostominae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae. Most members of the subfamily are restricted to tropical and subtropical South America, but there are also several species (in genera Ancistrus, Chaetostoma, Lasiancistrus, Leptoancistrus and Hemiancistrus) in southern Central America. Hypostomus plecostomus, which is popular in the aquarium trade, has been introduced to several regions far from its native range. Studies conducted with representatives of some genera of Hypostominae showed, within this group, the diploid number ranges from 2n = 52 to 2n = 80.
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.
The smaller ariid catfishes have minor value as public and home aquarium fish. In 1972, the Shedd Aquarium in Chicago received worldwide acclaim for the first successful breeding of Ariopsis felis in captivity, a feat they have repeated several times since. The Colombian shark catfish Sciades seemanni (until recently Hexanematichthys seemanni) is a fairly popular aquarium fish, though it has been traded under a variety of spurious names, such as Arius jordani and Arius seemani.Hexanematichthys seemanni Less commonly traded aquarium species include Arius berneyi and Arius graeffei.
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.
101) but the fish is capable of living in temperatures from 21 °C to 28 °C, and indeed usually breeds at around 28 °C (82.4 °F). The harlequin rasbora is a shoaling fish, and should be kept in a group comprising a minimum of six individuals, though shoals of larger numbers are preferable not only from the standpoint of the well-being of the fish, but from an aesthetic standpoint—a large shoal of harlequin rasboras presents a striking vista even to non-fishkeepers, and their active disposition in the water adds to the spectacle. Being a peaceful species, the harlequin rasbora may be maintained in a community aquarium set-up with other similarly sized and peaceful aquarium fishes, including many of the small characins from South America (the similarity in water chemistry of the two habitats for these different fishes has already been covered), assorted small barbs, danios, other small rasboras, Corydoras catfishes, Otocinclus catfishes and others. An aquarium intended to house harlequin rasboras should be planted with live plants, with some open areas for swimming provided between stands of plants such as Cryptocoryne species, these being among the plants that inhabit the harlequin rasbora's native waters.
The Delturinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae, including two genera, Delturus and Hemipsilichthys. This group is sister to all other loricariids except Lithogenes. The geographical distribution of Delturinae, exclusively on the southeastern Brazilian Shield, indicates southeastern Brazil acts as either a refugium for basal loricariid taxa or a point of origin for the Loricariidae. Both genera can be separated from all other loricariids by the presence of a postdorsal ridge made up of raised, median, unpaired plates and the presence of an adipose fin membrane.
This shark feeds on a variety of crustaceans (crabs, slipper lobsters, and spiny lobsters), bony fishes (including morwongs, sea catfishes, drums, and porgies), and cephalopods (in particular Octopus vulgaris). Sharks and rays (including catsharks and guitarfishes) and their egg capsules are a minor food source for larger individuals. Off South Africa, the most important prey species is the crab Plagusia chabrus. Its dietary composition changes with age; young sharks under long subsist almost completely on crabs, while larger sharks consume more bony fishes and cephalopods, as well as a greater variety of prey overall.
In common with most Corydoras the dorsal, pectoral and adipose fins have an additional sharp barb and have a mild poison which causes fish which try to attack them to get stung. A brownish-orange patch is usually present on the head, just before the dorsal fin, and is its most distinctive feature when viewed from above in the stream. Their upper sides are often a greenish color, which is the reason another common name for this fish is the green corydoras. Like many other catfishes, females are larger than males in this species.
The Kukwari sea catfish, Amphiarius phrygiatus is a species of sea catfish which occurs in brackish estuaries with very low salinities, nearly entering freshwater, and is found on shallow muddy bottoms, ranging through Venezuela, Guyana, Surinam, French Guiana, and Brazil. It grows to about 30 centimetres (12 in) TL. As with other Arriid catfishes this species is a mouthbrooder. The female A. phrygiatus lays her eggs in a gelatinous mass on a sandy depression for the male to collect to mouthbrood. This species is caught for human consumption.
Liobagrus kingi, the King's bullhead, is a species of catfish in the family Amblycipitidae (the torrent catfishes) endemic to China, where it is known to occur in the lake Dianchi basin, in its tributaries and effluent river, the Zhangjiu, and two tributaries of the Jinshajiang (upper Yangtze) river in Sichuan and Yunnan. It has not been recorded in the lake since the 1960s.Wang, Wang, Li, Du, Yang, Lassoie, and Hassan (2013). Six decades of changes in vascular hydrophyte and fish species in three plateau lakes in Yunnan, China.
Although zig-zag eels are often combined with medium to large-sized gouramis, knifefish, danios, loaches, Loricariids, eartheaters, acaras, Cichlasomines and Asian catfishes in a community fish aquarium, they are not normally mixed with small-sized fish, because tire track eels are observed to prey upon smaller fish. Mixing them with fish belonging to the same species is also not recommended. This is because they are aggressive to members of the same fish family but peaceful to other fish species with similar care level requirements, size and temperament.Tire Track Eel (Mastacembelus armatus), Aqua-Fish.
He has worked with leading ichthyologists both Thais and foreigners such as Kittipong Jaruthanin, T. R. Roberts, H. H. Ng and Maurice Kottelat etc. He has studied and taxonomy many of the newly discovered freshwater species in the world (many were found in Mekong Basin) such as Amblypharyngodon chulabhornae, Himantura kittipongi, Pangasius conchophilus, P. myanmar, Pao palustris, Pseudeutropius indigens, Schistura pridii etc. He specializing in Thai freshwater catfishes. In addition, he is also an instructor on zoology and ichthyology at several educational institutions in Thailand such as Chulalongkorn University, Kasetsart University or Mahasarakham University etc.
Hoplomyzon is a genus of banjo catfishes that are native to tropical South America. Hoplomyzon species are small, armoured aspredinids, growing up to 32 millimetres (1.3 in) SL in H. sexpapilostoma. Members of this genus are distinguished from all other aspredinids by having each premaxilla with two bony knobs superficially covered by fleshy papillae, the dorsal and ventral armor plates not overlapping, and 2-3 sets of paired pre-anal-fin plates. They also have the maxillary barbels adnate with the head and the pectoral spine less than one-quarter of the fish's standard length.
The reservoirs at Tilaiya and Maithon, provided scope for development of fisheries. Efforts were made to introduce carp once the water accumulated behind the dams but the results have not been commensurate with the efforts, largely due to the formidable presence of predatory catfish Wallago attu and other predators such as Notopterus chitala and Barilius bola at Tilaiya, and catfishes Wallago attu and Aorichthys aor, at Maithon. These predators take a heavy toll of the stocked carps. Trash and uneconomic fishes form dense populations at Tilaiya reservoir, competing with major carps for food.
Nearly half the species of madtom catfishes were described in a single comprehensive revision of the group. Morphology is very conserved in this genus; most of the species look very similar and telling them apart with the usual meristic and morphometric characters used to identify species is difficult. The more conspicuously variable attributes of these secretive fishes are features of pigmentation, which also are more difficult to quantify and often vary according to substrate and water quality. These species have small to tiny or fragmented ranges, and aspects of pigmentation are important diagnostic characters of each.
The tail fin is formed by the joining of the second dorsal fin, the caudal fin, and the anal fin, forming a single, continuous fin. Some of these catfishes can inflict painful wounds; stings from Plotosus lineatus may cause death, however stings from other types of eeltail catfish causes stinging which usually resides up to two weeks from when the person was penetrated by its dorsal spines. They are bottom feeders and use the barbels around their mouths to detect food. Unlike most marine teleosts, eeltails have an extra- branchial salt-secreting dendritic organ for osmoregulation.
Southern African pilchard are the most important prey species of copper sharks off South Africa. The copper shark feeds more towards the bottom of the water column than the top, consuming cephalopods, including squid (Loligo spp.), cuttlefishes, and octopus; bony fishes, including gurnards, flatfishes, hakes, catfishes, jacks, Australian salmon, mullets, sea breams, smelts, tunas, sardines, and anchovies; and cartilaginous fishes, including dogfish sharks (Squalus spp.), stingrays, skates, electric rays, and sawfishes. Cephalopods and cartilaginous fishes become relatively more important food for sharks over long. Young sharks also consume scyphozoan jellyfish and crustaceans, including mud shrimps (Callianassa) and penaeid prawns.
The majority of the species are in the family Cichlidae, popular with aquarists, but there are also lungfishes, elephant- noses, mastacemblid eels and catfishes. They are often very colourful and have interesting behaviours - making for fascinating fish-watching. The great diversity in the lake means that most species have unique adaptations and occupy specialised ecological roles in the lake. Some scrape algae from the rocks, some filter sand, some eat snails, some live in empty snail shells, some eat plants, some eat fish, some eat scales, some mimic dead fish to allow them to catch unwary prey.
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".
When the muscles relax, the tension in the spring quickly returns the swimbladder to its original position, which produces the sound. Catfish also have a sound-generating mechanism in their pectoral fins. Many species in the catfish family possess an enhanced first pectoral fin ray, called the spine, which can be moved by large abductor and adductor muscles. The base of the catfishes' spines has a sequence of ridges, and the spine normally slides within a groove on the fish's pelvic girdle during routine movement; but, pressing the ridges on the spine against the pelvic girdle groove creates a series of short pulses.
Xyliphius is a genus of banjo catfishes from South America. This genus appears to be widespread in the Magdalena, Orinoco, Amazon, and Paraguay-Paraná River systems where they are most common in deeper waters. Xyliphius includes moderately sized aspredinids, ranging from 8.8-14.7 centimetres (3.5-5.8 in) SL. Species of this genus are distinguished from all other aspredinids by having highly reduced eyes, toothless premaxillae, a row of fleshy papillae projecting anteriorly off the lower lip, flattened unculi and unculiferous tubercles flattened. These species also have the openings of the anterior nares with papillae and no dark saddles on the body.
The varying habitats found within the lake support a large number of fish species, more than any other lake in Canada west of the Great Lakes. Sixty of seventy- nine native species found in Manitoba are present in the lake. Families represented include lampreys (Petromyzontidae), sturgeon (Acipenseridae), mooneyes (Hiodontidae), minnows (Cyprinidae), suckers (Catostomidae), catfishes (Ictaluridae), pikes (Esocidae), trout and whitefish (Salmonidae), troutperch (Percopsidae), codfishes (Gadidae), sticklebacks (Gasterosteidae), sculpins (Cottidae), sunfishes (Centrarchidae), perch (Percidae), and drums (Sciaenidae). Two fish species present in the lake are considered to be at risk, the shortjaw cisco and the bigmouth buffalo.
In traditional schemes, the family Diplomystidae is the basal, primitive sister group to all other catfishes (Siluroidei). This is well supported by morphological evidence. Almost all molecular estimates of catfish phylogeny, by contrast, find Diplomystidae sister to Siluroidei, with Loricarioidei (the armoured catfish and relatives) the most basal group; though this may be an artifact of rapid evolution in loricarioids. Diplomystids retain more plesiomorphic characteristics than any other siluriforms, recent or fossil, including aspects of the maxillary bones, barbels, nares, otic capsule, anterior pterygoid bones, Weberian complex centra, caudal skeleton, and fin rays, and pectoral girdle.
Roberts, T.R. (2014): Wallago Bleeker, 1851 and Wallagonia Myers, 1938 (Ostariophysi, Siluridae), Distinct Genera of Tropical Asian Catfishes, with Description of †Wallago maemohensis from the Miocene of Thailand. Bulletin of the Peabody Museum of Natural History, 55 (1): 35-47. The other two species of the genus Wallagonia, W. micropogon from the Mekong river basin and W. maculatus from the Kinabatangan river basin on Borneo, are currently considered as distinct species. There are, however, strong suspicions that they may in fact be subspecies of W. leerii, as the sole difference seems to lie in a slightly different coloration.
The Vandelliinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. Vandelliines are hematophagous, feeding on the blood of larger fish. Members of this subfamily may be known as candirú, notorious for occasionally entering human bodily orifices, particularly the urethra; no evidence indicates such attacks are anything more than rare and accidental perversions of the usual feeding behaviour of the parasite — it seems unlikely that it would survive in the human body for long, so such an entry should be disastrous for both parties. In the usual course of events, parasitic vandelliines enter the body cavities of host fishes, feed on blood from gill filaments, and leave again.
Fish less than 3 cm are likely to be consumed. If kept with significantly larger but non-aggressive fish, such as Geophagus cichlids, large Synodontis catfishes, or larger gouramis, they are usually submissive and do not act nearly as aggressively as when they are the dominant species in the aquarium. However, they themselves can be bullied by similar sized or even smaller fish if that fish has already established territory in the tank which it is not willing to share or give up. If this is the case they will not even attempt to fight and will take to hiding behind filters, plants, or in décor, and will succumb to stress.
Ichthyology has also been a part of Academy collections and research since its beginnings, but the size of the collection was relatively modest until acquisition of Edward Drinker Cope's personal collections in 1898. A few years later, Henry Weed Fowler began his tenure at the Academy, during which he systematized the collections and described 1,408 species. James Edwin Böhlke, William Saul, and William Smith-Vaniz are among the notable scientist who followed Fowler. The current curator, John Lundberg, an expert in catfishes, pioneered deep channel collecting in large tropical rivers and is the lead author of a seminal scientific paper on the biological and geographic history of the Amazon River Basin.
All species of catfishes can generate sound through stridulation, and many produce sounds through drumming. Stridulation consists of the clicking or grinding of bony parts on the fish's pectoral fins and pectoral girdle, and drumming consists of the contraction of specialized sonic muscles with subsequent reverberation through the swim bladder. Variability in the sound signals created by the channel catfish depends on the mechanism by which the sound is produced, the function of the resultant sound, and physical factors such as sex, age, and temperature. This variation may result in increased complexity of the outgoing signal and may allow for increased usefulness of the signal in interspecies communication.
These species are easily distinguished by the presence of pinnate processes along the median caudal-fin rays (although these processes may be poorly developed in some species), a prominent cup-like skin flap above the base of the pectoral spine and the adipose fin largely separate from the caudal fin. In most species the caudal fin is deeply forked; A. apangi and A. murraystuarti differ in having their caudal fin truncate. Amblyceps species may reach about 100 millimetres (3.94 in) SL.Chen, X. & Lundberg, J.G. (1995): Xiurenbagrus, a New Genus of Amblycipitid Catfishes (Teleostei: Siluriformes), and Phylogenetic Relationships among the Genera of Amblycipitidae. Copeia, 1995 (4): 780–800.
Mainland Asia, the Malay Peninsular, Sumatra and Java became connected to Borneo via the landbridge of exposed Sunda Shelf. The North Sunda River provided vital connection to Mekong River in Vietnam and Chao Phraya River in Thailand to the north, Baram and Rajang rivers in Sarawak to the east and Pahang River and Rompin River to the west of the massive land mass. Freshwater catfishes from those rivers migrated and mated to exchange their genetic materials about 10,000 years ago. Thus, after the Holocene, when the temperature increased, a substantial amount of the ice that had accumulated melted, increasing sea levels, inundating the landbridges and Sunda River, thus isolating the catfish populations.
Catfish of this size is a rarity and, as required by the law, it was returned in to the lake. Other catfishes of this size were reported by the divers in previous years, but they lay lazily on the bottom of the lake, not swimming to the surface. There are 20 to 25 fish species in the lake, including the autochthonous carp, northern pike, zander, common bream, asp and European perch, and the imported, and highly invasive brown bullhead, Prussian carp and pumpkinseed. There are also crayfish and crabs, and since 2010s, the red-eared slider inhabits the lake, too, probably being released in the lake by the owners who kept them as pets.
Liobagrus chenghaiensis is a species of catfish in the family Amblycipitidae (the torrent catfishes) endemic to China, where it is only known from lake Chenghai in the province of Yunnan. L. chenghaiensis is distinguished from all other species of Liobagrus with a serrated posterior margin of the pectoral- fin spine by possessing a free apex on the posterior margin of the adipose fin. It is similar to L. marginatus in the presence of a subtruncate caudal fin, by which both are distinguished from all other Chinese congeners with a serrated posterior margin of the pectoral-fin spine. These two species are distinguished by differences in the body depth and the distance between the pelvic-fin insertion and the vent.
The aquarist is advised, however, that the traditional use of Corydoras catfishes as putative 'scavengers' in an aquarium setting will be detrimental to the well-being of this species—it requires high quality foods for long-term maintenance, and a varied diet. Ideally, the fish should be given live foods at least intermittently, and will dine enthusiastically upon such items as Bloodworms (larvae of Chironomus midges), Daphnia, cultivated Brine Shrimp (Atermia salina), and Tubifex worms. The last, however, should be cultivated in order to minimise the risk of introducing pathogenic organisms to the aquarium, as Tubifex live in unsanitary conditions in the wild. Freeze dried Tubifex may be preferable, as the risk of introduction of disease is eliminated.
Once the female is carrying a fertilised egg within her pelvic fins, she then seeks an egg deposition site. The choice of such a site is frequently, though not always, a mass of fine leaved aquatic vegetation. In the aquarium, the plant known as Java moss, Vesicularia dubayana, is of considerable utility as an egg repository for Corydoras catfishes, even though the plant is not a South American native, and panda catfish females will choose large clumps of this plant readily as safe deposition sites for fertilised eggs. The female is frequently pursued by one or more males as she seeks the deposition site, each male presumably seeking to be the chosen mate to fertilise the next egg.
Their species include 56 of cartilaginous fishes and 386 of bony fishes. The 266 species of inland fishes belong to 61 families, of which Cyprinidae is the largest, having 61 species. There are also 55 species of catfishes found in the fresh waters of Bangladesh. The amphibians in Bangladesh include only the species of the order Anura. From the 22 amphibian species, 8 are recognized as threatened. The number of reptiles species found is 126 which includes 109 inland and 17 marine species. From the 109 inland reptiles, 2 are crocodilians, 21 turtles and tortoises, 18 lizards, and 67 snakes. The marine reptiles comprise 12 snakes and 5 turtles. There are 628 species of birds found in Bangladesh under 16 orders and 67 families, including 276 passerines.
Eventually, one male will succeed in courting a female, using his barbels to provide stimulation to the female, usually beginning with caresses of the female's caudal peduncle, followed by caresses of the fontanel and the front of the head. if the female is receptive, then the male positions himself before the female, so that the female's mouth is in close proximity with one of the male's pectoral fins. The male then clasps the female's barbels between the pectoral fin and the body, and this stimulates the female to press against the male's side. When seen from above, the fish form a 'T' shape when conjoined thus, hence the term 'T position' has become conventional in aquarium circles when describing the breeding of Corydoras catfishes.
A wide variety of commercially viable fish, 27 species of 5 families, such as mahseer, catla, mirror carp, singhara (native) and others are recorded in the Pong Dam reservoir and its tributaries. Before the reservoir was built, catfishes, mirror carps and a few coarse fish were the dominant fish fauna in the Beas River. With the emergence of the reservoir, commercial fishing was encouraged as an important programme not only to provide employment to about 1500 fishermen but also to promote the eco-tourism potential. A planned operation of fish stocking was launched with first introduction of common carp in 1974 and Indian major carps or silver carp in 1976-77\. This resulted in a shift in the catch structure of the reservoir, with carps accounting for 61.8% of the total landings in 1987-88\.
Though the family is commonly known as "parasitic catfishes", Trichomycteridae may actually include the widest range of trophic adaptations within any single catfish family. Only the two subfamilies Vandelliinae and Stegophilinae and Tridensimilis of Tridentinae are considered to be parasitic fishes, including the infamous candirú or vampire catfish, feared by some people for its habit of entering into the urethra of humans. Apart from the free-living, generalized predators of small invertebrates, trophic modes represented by trichomycterids include the hematophagy (feeding on blood) in Vandelliinae, the lepidophagy (scales) and mucophagy (mucus) in some Stegophilinae and necrophagy (carrion) in others, and partial algivory (algae) in Copiondontinae. Trichomycteridae include species that are active swimmers (Copionodontinae and Trichogeninae), torrent dwellers (Trichomycterinae), litter leaf dwellers (Ituglanis), and sand dwellers (Glanapteryginae and Sarcoglanidinae).
The lips were once believed to be unable to function as a sucker while respiration continued, as the inflowing water would cause the system to fail; however, respiration and suction can function simultaneously. Inflowing water passing under the sucker is limited to a thin stream immediately behind each maxillary barbel; the maxillae in loricariids support only small maxillary barbels and are primarily used to mediate the lateral lip tissue in which they are embedded, preventing failure of suction during inspiration. To achieve suction, the fish presses its lips against the substrate and expands its oral cavity, causing negative pressure. Also, unlike most other catfishes, the premaxillae are highly mobile, and the lower jaws have evolved towards a medial position, with the teeth pointed rostroventrally; these are important evolutionary innovations.
Their scales and skeletons began to lighten during their evolution, and their jaws became more powerful and efficient. While electroreception and the ampullae of Lorenzini are present in all other groups of fish, with the exception of hagfish (although hagfish are not actinopterygians, they are agnathans), neopterygians have lost this sense, even if it has later been re-evolved within Gymnotiformes and catfishes, which possess nonhomologous teleost ampullae.Electroreception By Theodore Holmes Bullock A very important step in the evolution of the actinopterygian fishes is the origin of the neopterygians, with the acquisition of a better control of the movements of both dorsal and anal fins, resulting in an improvement in their swimming capabilities. They additionally acquired several modifications in the skull, which allowed the evolution of different feeding mechanisms and consequently the colonization of new ecological niches.
Liobagrus aequilabris is a species of catfish in the family Amblycipitidae (the torrent catfishes). This species is endemic to China, where it is only known from the Xiang River, a tributary of the Yangtze River, in Guangxi province, but may also be present in the Li River, a tributary of the Pearl River, due to the presence of the Lingqu Canal connecting the Xiang and Li Rivers. L. aequilabris reaches a length of SL. It differs from other members of its genus in lacking large, retrorse serrations on the posterior edge of the pectoral-fin spine, having upper and lower jaws of equal length, relatively long dorsal (7.5-10.2 % of SL) and pectoral-fin (9.1-12.1 % of SL) spines, a relatively long caudal fin (20.1-26.9 % of SL), and relatively few post-Weberian vertebrae (35-37).
Liobagrus somjinensis is a species of catfish in the family Amblycipitidae (the torrent catfishes). It is known from the western and southern coasts of Korea and Geogeum Island, where it has been found in rivers and tributaries. L. somjinensis can be distinguished physically from other torrent catfish by the unusual length of its dorsal spine and outer mental barbel (7.3–12.4 % of SL and 15.3–21.6 % of SL respectively) and the shortness of the distance from its dorsal-fin insertion point to its adipose-fin point of origin (13.5–22.0 % of SL), as well as by markings and coloration on the fins. The caudal fin displays a broad vertical band in its center, yellow in hue and shaped like a crescent, while the dorsal, anal, and caudal fins have deep black colour on their outer margins.
Established species include P. multiradiatus in Florida and Hawaii, P. disjunctivus in Florida, and P. anisitsi in Texas. Sailfin catfish are one of the more successful established exotic fish in Florida in terms of their range extension and abundance, yet their presence has not had any measurable effect on native fishes, although they have contributed significantly to the carrying capacity of some fish communities. Moreover, none of the 30 professional water managers, engineers, lake management, and shoreline stabilization company owners contacted in 2004 by a particular study considered erosion caused by the burrowing activity of loricariid catfishes a major problem, except in some man-made lakes in the southeastern part of the state. In Mexico, P. multiradiatus is established in Campeche, Chiapas, and other localities in central and western Mexico, while P. pardalis has been found in southeastern Mexico.
Suitable companions in an aquarium include other tetra species, small barbs, small danios, small rasboras, Corydoras and Otocinclus catfishes, and in aquaria where space allows, certain species of dwarf cichlid such as the smaller Apistogramma species. Tankmates should be chosen to be peaceful, not too large, and a more natural display results if the companion fishes chosen are other South American species. An aquarium containing large shoals of lemon and cardinal tetras makes a particularly stunning display, the blue and red of the Cardinals contrasting with the brilliant yellow and black of the lemons. While the preference of the lemon tetra with respect to water chemistry lies within the realm of soft (hardness less than 8° dH) and acidic (pH around 6.6) parameters, the species is notably hardy, and will accommodate itself to a wide range of conditions, the pH range for the fish being from 6.0 to 7.4.
Francisco Mago Leccia . Eigemania viricens (Gymnotiformes: Sternopygidae) Francisco Mago Leccia (“Mago”) was born in Tumeremo, Bolívar State, Venezuela on May 21, 1931 and died in Puerto La Cruz, Anzoátegui State, Venezuela on February 27, 2004.Schaefer, Provenzano, Pinna & Baskin (2005) - New and Noteworthy Venezuelan Glanapterygine Catfishes (Siluriformes, Trichomycteridae), with Discussion of Their Biogeography and Psammophily. American Museum Novitates, No. 3496, Mago was a distinguished Venezuelan ichthyologist who specialized in electric fish of the rivers and lagoons of South America, particularly of Venezuela. His education was Docent in Biology and Chemistry graduate from the “Instituto Pedagógico de Caracas”, (today Universidad Pedagógica Experimental El Libertador), Master of Sciences (Marine Biology) from the University of Miami, Florida, U.S.A., Doctor in Sciences from Universidad Central de Venezuela. His Doctoral Thesis was entitled: “Los peces Gymnotiformes de Venezuela: un estudio preliminar para la revisión del grupo en la América del Sur” (The Gymnotiformes fish of Venezuela: a preliminary study for the revision of the group in South America).
Once the male and female are in the 'T position', the pressing of the female against the male's body stimulates his release of sperm. Though the exact mechanism of fertilisation has yet to be scientifically documented, from the observations of aquarists who have been successful in breeding Corydoras catfishes, it seems likely that the female takes the male's sperm through her mouthparts, and directs them through the gills, in a current that carries the sperm to her pelvic fins. At this point, the female releases a single egg (occasionally two), and purses her pelvic fins in order to provide a receptacle for the freshly extruded egg, which is then fertilised. One difference observed between the adoption of the 'T position' in Corydoras panda, when compared to other Corydoras species, is that the exercise is frequently more acrobatic in appearance, with the 'T position' being adopted in mid-water, some distance above the substrate, rather than resting upon the substrate as is the case with the majority of other Corydoras.
