Catfish 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, 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". 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. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.
Thelypteridaceae is a family of about 900 species of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the suborder Aspleniineae. Alternatively, the family may be submerged in a very broadly defined family Aspleniaceae as the subfamily Thelypteridoideae.
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera.
The Dryopteridaceae are a family of leptosporangiate ferns in the order Polypodiales. They are known colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae sensu lato.
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial.
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species.
The Bagridae are a family of catfish that are native to Africa (Bagrus) and Asia from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes.
Schilbeidae is a family of catfishes native to Africa and Asia. These fish tend to swim in open water.
Horabagrus is a genus of catfish in the family Horabagridae endemic to rivers in the Western Ghats in Kerala and Karnataka, India. H. brachysoma is an important food fish and members of this genus can be found in the aquarium trade.
Ailia is a genus of catfish in the family Ailiidae native to Asia. It is called "Kajoli" or "Bahpati" in Assamese and contributes to a major catch in Brahmaputra River. It is a surface to mid water fish that is found commonly near the shoals.
Guihaia is a genus of three species of dioecious palms found in China and Vietnam. Perhaps its most distinctive characteristic is that it is the only palm with palmate leaves that has reduplicate (A-shaped) leaf folds. All other palmate leaves have induplicate (V-shaped) leaf folds. Guihaia lancifolia has undivided leaves.
Acanthomorpha is an extraordinarily diverse taxon of teleost fishes with spiny rays. The clade contains about one-third of the world's modern species of vertebrates: over 14,000 species.
Laides is a genus of catfish in the family Ailiidae native to Asia. These species are originates from Mekong and Chao Phraya River basins.
Tectariaceae is a family of leptosporangiate ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Tectarioideae of a very broadly defined family Polypodiaceae sensu lato. The family comprises seven genera, of which Tectaria is by far the largest.
Ailia coila, also known as the Gangetic ailia is a species of catfish in the family Ailiidae native to India, Bangladesh, Nepal and Pakistan. This species grows to a length of 30 centimetres (12 in) TL.
Ailia punctata, also known as the Jamuna ailia is a species of catfish in the family Ailiidae native to Bangladesh, India and Pakistan. The species is heavily fished and other threats include habitat loss, pollution and introduced species but the exact effects are unknown. This species grows to a length of 10.0 centimetres (3.9 in) TL.
Clupisoma is a genus of catfish in the family Ailiidae native to Asia.
Pseudeutropius is a genus of catfishes conventionally placed in the family Schilbeidae but recent work has suggested it be placed in the newer family Horabagridae, the genus is native to Asia.
Ailiidae is a family of catfishes native to Asia. These fishes usually have dorsal fins with a short base and a spine, but Ailia lack a dorsal fin altogether.
Phenuiviridae is a family of negative-strand RNA viruses in the order Bunyavirales. Ruminants, camels, humans, and mosquitoes serve as natural hosts. Member genus Phlebovirus is the only genus of the family that has viruses that cause disease in humans except Dabie bandavirus.
