 There are armour-plated types and also naked types, neither having scales. Despite their name, not all catfish have prominent barbels; members of the Siluriformes order are defined by features of the skull and swimbladder. .Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food.^ Commercial fishing is also unregulated in many areas.

Physical characteristics

External anatomy of catfish

Most catfish are bottom feeders. .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.^ Acknowledging devolution means acknowledging that not only are things worse than we've dared to admit, they are getting worse, and will continue to do so, at an ever accelerating pace.

 [3] Catfish have a variety of body shapes, though most have a cylindrical body with a flattened ventrum to allow for benthic feeding.[3]
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.^ Jeff Wiborg, No need to take large Catfish.

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.^ But if you get the inside scoop on how to detect more strikes, you can easily increase the amount of catfish you catch by 300%...

 Like other ostariophysans, they are characterized by the presence of a Weberian apparatus.[1] Their well-developed Weberian apparatus and reduced gas bladder allow for improved hearing as well as sound production.[3]
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.^ Bonus #4: Special Report #2: “Cutting Through The Crap” Catfish Fishing Equipment Report ($49 value, with lifetime updates) .

 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.^ The observation that the result of our evolutionary process, may, in the end, shed most of its object-oriented baggage should support, and not undermine our tale...

 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.[9]
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.[2] .In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.^ (Ron used the exact same bait for both species, and only altered it slightly to slam the catfish...

 [10] This venom is produced by glandular cells in the epidermal tissue covering the spines.[1] 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.[1]

Internal anatomy

In many catfish, 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.[16]
The retina of catfish are composed of single cones and large rods. Many catfish have a tapetum lucidum which may help enhance photon capture and increase low-light sensitivity. Double cones, though present in most teleosts are absent from catfish.[17]
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.[18] 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.[19] The total number of fringes and their length are different in the caudal and cranial portions between species.[18] Fringes of the caudal region may present tubules, in which the lumen is filled by secretion and spermatozoa.[18] Spermatocysts are formed from cytoplasmic extensions of Sertoli cells; the release of spermatozoa is allowed by breaking of the cyst walls.[18]
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 phospholipids.[13]
Fish ovaries may be of two types: gymnovarian or cystovarian. In the first type, the oocytes are released directly into the coelomic cavity and then eliminated. In the second type, the oocytes are conveyed to the exterior through the oviduct.[19] Many catfish are cystovarian in type, including Pseudoplatystoma corruscans, P. fasciatum, Lophiosilurus alexandri, and Loricaria lentiginosa.[18][19]

 Since 2007, the Goonch catfish has also gained attention following a series of fatal underwater attacks which have been alleged by biologist Jeremy Wade to have been from unusually large goonch. .The Wels catfish has also been reputed to kill humans (especially young children), and while there are no documented cases of fatalities, larger specimens are known to cause serious injuries in rare instances (probably from defensive reactions rather than attempted predation).^ (Seriously, there is no comparison.

 In addition, other species are reputed to be dangerous to humans as well, but with less definitive evidence.

Taxonomy

The catfishes are a monophyletic group. This is supported by molecular evidence.[34]
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.[1] As of 2007 there are about 36 extant catfish families, and about 3,023 extant species have been described.[35] .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.^ A big blunder most beginners make after a fishing trip… that guarantees they’ll lose at least one catfish the next time out!

 ^ Catfish are one of the top five most fished for species.

 [2]
The taxonomy of catfishes is quickly changing. In a 2007 and 2008 paper, Horabagrus, Phreatobius, and Conorhynchos were not classified under any current catfish families.[35] .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.^ The ultimate “lazy man’s” commercial catfish bait that blows all others out of the water.

 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.[1][36][37][38] Many sources do not list the recently revised family Anchariidae.[39] The family Horabagridae, including Horabagrus, Pseudeutropius, and Platytropius, is also not shown by some authors but presented by others as a true group.[34] 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.^ When they found a new technique for catching catfish, they didn’t tell a soul… because it wouldn’t work as well if everyone else started using it.

 On the other hand, our understanding of catfishes should increase in the next few years due to work by the ACSI.[1]
.The rate of description of new catfishes is at an all-time high.^ (It’s perfectly legal and Randy uses it to catch catfish, bass, bluegill, eel, and turtle all at the same time!

 ^ If you want it all, right now – and you’re serious about catching more (and bigger) catfish the next time you go fishing… this is the option for you.

 The new species in Lacantuniidae, Lacantunia enigmatica, was found in the Lacantun river in the Mexican state of Chiapas.[41]
According to 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.^ Evidence suggests that cut ‘n’ paste is a nearly essential, and nearly universal, practice when new framework applications are constructed, be they for GUI code, Eclipse plug-ins, or what have you.

 ^ They remind me of so many experiences, and all the different tactics for catching catfish.

 Siluroidei was found to be monophyletic without Loricarioid families or Diplomystidae with molecular evidence; morphological evidence is unknown that supports Siluroidei without Loricarioidea.[34]
Below is a list of family relationships by different authors. Lacantuniidae is included in the Sullivan scheme based on recent evidence that places it sister to Claroteidae.[42]

Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Superorder: Ostariophysi
Order: Siluriformes

Catfish are a group of teleost fish. Their Latin name is Siluriformes. They are named catfish because their barbels look like the whiskers of a cat. They are very diverse. They range in size from the heaviest, the Mekong Giant Catfish to the longest, the Wels catfish found in Eurasia. There are also detrivores in the group, and even tiny parasitic fish can be found. These parasites are called candiru. Some catfish are also grown for food, in fish farms. Some catfish can be kept in aquaria.
