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 7,000,000 km2 (2,700,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana.
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. This genus is a strongly supported clade of this family. It consists of a natural group in which the monophyly is well-defined by morphological and molecular evidence and the genus probably includes several unrecognized species from both American coasts.
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.
Aspistor is a genus of sea catfishes found along the northeastern coast of South America, where they occur in marine, brackish, and fresh waters.
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.
Cochlefelis is a genus of sea catfishes found in coastal and freshwaters from Southeast Asia to Australia. There are currently four described species in this genus.
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:
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.

Aspistor hardenbergi is a species of sea catfish in the family Ariidae. It was described by Patricia J. Kailola in 2000, originally under the genus Arius. It inhabits tropical marine and brackish waters in southern New Guinea. It reaches a maximum standard length of 25.4 cm (10.0 in).
Neoarius graeffei, or blue salmon catfish, is a species of catfish found in freshwater rivers of Australia and Papua New Guinea. This species is most identifiable by its large, shark-like dorsal fin that is led by a poisonous spine. Like other catfish, the blue salmon catfish is known to use electrical pulses to sense prey in the water. This prey sensing mechanism may be the reason that these catfish are known to eat the land dwelling hopping mouse at a high rate.
Cochlefelis insidiator, the flat catfish, is a species of catfish in the family Ariidae. It was described by Patricia J. Kailola in 2000, originally under the genus Arius. It occurs in rivers, mudflats and marine waters on the coasts of Papua New Guinea and Australia. It reaches a standard length of 35 cm (14 in).
Neoarius leptaspis, the salmon catfish, boofhead catfish, freshwater forked tailed catfish, lesser salmon catfish, or triangular shield catfish, is a species of catfish in the family Ariidae.

It reaches a maximum standard length of 50 cm (20 in).

Neoarius pectoralis, the sawspine catfish or sawspined catfish, is a species of catfish in the family Ariidae. It was described by Patricia J. Kailola in 2000, originally under the genus Arius. It inhabits marine and brackish waters in Australia, Irian Jaya, and possibly also Papua New Guinea. It reaches a maximum fork length of 39.3 cm (15.5 in).
Neoarius utarus, the northern rivers catfish or salmon catfish, is a species of catfish in the family Ariidae. It was described by Patricia J. Kailola in 1990, originally under the genus Arius. It inhabits freshwater bodies in Indonesia and Papua New Guinea.
