Nedystoma is a genus of sea catfishes endemic to the island of New Guinea where they are found in fresh and brackish waters in both the Indonesian portion and in Papua New Guinea. There are currently two described species in this genus.
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.
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.
Euristhmus is a genus of eeltail catfishes native to the eastern Indian-western Pacific Oceans around Australia, New Guinea and Indonesia.
Neosilurus is a genus of eeltail catfishes native to Australia and New Guinea.
Chiloglanis is a genus of upside-down catfishes native to Africa. These species have modified lips and barbels that form a suckermouth. They also have a naked (scaleless) body. Sexual dimorphism has been reported in Chiloglanis. The adult males of many of these species have elongate anal and caudal fins. Also, males may have an enlarged humeral process.
Cinetodus is a genus of sea catfishes of the family Ariidae. These species originate from brackish and fresh waters of Irian Jaya, southern New Guinea and northern Australia.
Amissidens hainesi, the Ridged catfish, is the only species of catfish in the genus Amissidens of the family Ariidae. This species occurs in marine and brackish waters on the southern coast of New Guinea and Northern Australia, between Darwin and southern Gulf of Carpentaria.
Malapterurus barbatus is a species of electric catfish native to Guinea, Sierra Leone and Liberia. This species grows to a length of 21.5 centimetres (8.5 in) SL.
Malapterurus occidentalis is a species of electric catfish native to Gambia and Guinea-Bissau, where it occurs in the Gambia and Géba Rivers. This species grows to a length of 32 centimetres (13 in) SL.
Malapterurus punctatus is a species of electric catfish native to Côte d'Ivoire, Guinea, Liberia and Sierra Leone. This species grows to a length of 21.49 centimetres (8.46 in) SL.
Malapterurus stiassnyae is a species of electric catfish native to Guinea, Liberia and Sierra Leone. Members of this species grow to a length of 30 centimetres (12 in) SL.
Malapterurus teugelsi is a species of electric catfish endemic to Guinea where it occurs in the Kogon River. This species grows to a length of 21.2 centimetres (8.3 in) SL.
Chiloglanis batesii is a species of upside-down catfish found widely in Western and Central Africa. This species grows to a length of 4.7 centimetres (1.9 in) TL.
Neoarius berneyi, the highfin catfish, Berney's catfish, Berney's shark catfish, or the lesser salmon catfish, is a freshwater sea catfish that is commonly kept in aquariums. The origin of the name Neoarius berneyi is Greek, with the genus name Neoarius coming from the words neos meaning new and arios, meaning warlike or hostile, in reference to the well developed fin spines, and the species name, berneyi, comes from the ornithologist F. L. Berney.
Hemiarius is a genus of sea catfishes found in the coastal waters, estuaries, and rivers from South Asia through New Guinea and Australia to Oceania. Four described species are in this genus:
Nemapteryx is a genus of sea catfishes found mostly in coastal marine and brackish waters from South Asia to Australia with one species occurring exclusively in fresh waters of the Fly River in Papua New Guinea. There are currently six recognized species in this genus.
Neoarius is a genus of sea catfishes found on and around the island New Guinea and Australia. They are found in marine, brackish waters and fresh waters with several species restricted solely to freshwater rivers. There are currently 10 described species in this genus.
The hard-palate catfish, also known as the hard-plate catfish, is a species of sea catfish in the family Ariidae. It was described by Albert William Herre in 1935, originally under the genus Arius. It is a tropical freshwater fish which is found in Indonesia and Papua New Guinea. It reaches a maximum standard length of 60 cm (24 in), with both sexes more commonly reaching an SL of 35 cm (14 in). It reaches a maximum weight of 1.8 kg (4.0 lb).
The Day's catfish is a species of catfish in the family Ariidae. It was described by Edward Pierson Ramsay and James Douglas Ogilby in 1886, originally under the genus Hemipimelodus. It inhabits turbid freshwater rivers in New Guinea. It reaches a maximum standard length of 20 cm (7.9 in). Its diet consists of the larvae of aquatic insects.
The Longsnouted catfish, also known as the Broadbent's catfish, the Spoon-nosed catfish, the Large-scaled catfish, the Sharp-headed catfish, or the Sand catfish, is a species of catfish in the family Ariidae. It was described by Achille Valenciennes in 1840, originally under the genus Arius. It inhabits brackish and marine waters in New Guinea, Australia, and southern and southeastern Asia. It reaches a maximum total length of 50 cm (20 in).
