Genidens is a genus of sea catfishes found along the Atlantic coast of South America. There are currently four recognized species in this genus. [1] [2]
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.
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fishes are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish.
The Amazon Basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 6,300,000 km2 (2,400,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, French Guiana (France), Guyana, Peru, Suriname, and Venezuela.
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.
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water.
Trichomycterus is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about 5 to 15 cm (2–6 in) in standard length, although the largest, T. rivulatus, can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration. Despite their relatively small size, some, such as T. punctulatus, support fisheries and are important in the local cuisine.
Brachyplatystoma is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to the region of 3.6 metres (12 ft) in length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Some species are migratory. These fish are important as food fish and, to some extent, aquarium fish.
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.
Pangasius is a genus of medium-large to very large shark catfishes native to fresh water in South and Southeast Asia. The term "pangasius" is sometimes used to specifically refer to the commercially important basa fish, P. bocourti.
Micromyzon is a genus of tiny catfish in the family Aspredinidae native to relatively deep parts of the Amazon and Orinoco basins in South America.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
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.
Ariopsis is a genus of sea catfishes found along the Pacific and Atlantic coasts of the Americas. The genus has been merged with Sciades by some authorities.
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.
Sciades is a genus of sea catfishes mostly found along the Atlantic Ocean and Caribbean Sea coasts of Central and South America. One species, S. dowii, occurs on the Pacific side from Panama to Ecuador, another, S. paucus, is a freshwater form found in Australia, while S. sona is a widespread species found along the Indian Ocean coasts of South Asia east into the Pacific to Polynesia. The genus Ariopsis has been merged with Sciades by some authorities.
The White sea catfish, also called the Marine catfish, is a species of catfish in the family Ariidae. It was described by Bernard Germain de Lacépède in 1803, originally under the genus Pimelodus. It is an oceanodromous species that is found between the Río de la Plata Basin and eastern Brazil. It reaches a maximum total length of 120 cm (47 in). It has been recorded spawning between the months of August–December. The maximum known life expectancy is 36 years.
The Guri sea catfish, also called the Marine catfish, is a species of catfish in the family Ariidae. It was described by Georges Cuvier in 1829, originally under the genus Pimelodus. It is known from southern South American rivers connected to the Atlantic Ocean. It is known to reach a total length of 42.5 cm (16.7 in), but more commonly reaches a TL of 35 cm (14 in). It has been recorded spawning between Autumn and Spring. Its diet includes polychaete worms, plants, finfish, mollusks, and benthic crustaceans.
Genidens machadoi is a species of catfish in the family Ariidae. It was described by Alípio de Miranda-Ribeiro in 1918, originally under the genus Tachysurus. It inhabits rivers along the south Atlantic coast in Argentina, Brazil and Chile. It reaches a total length of 80 cm (31 in).
Genidens planifrons is a species of catfish in the family Ariidae. It was described by Horacio Higuchi, Enir Girondi Reis and Francisco Gerson Araújo in 1982, originally under the genus Netuma. It migrates between the Lagoa dos Patos and the region of the Atlantic Ocean which it drains into. It reaches a standard length of 57 cm (22 in).
