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.
Galeichthys is a genus of sea catfishes in the family Ariidae, the only genus in the subfamily Galeichthyinae. It includes four predominantly marine species distributed in Southern Africa and northwestern South America:
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.
Amphiarius is a genus of sea catfishes of the family Ariidae. It includes two species, the Kukwari sea catfish, A. phrygiatus, and the softhead sea catfish, A. rugispinis.
Arius is a genus of catfishes of the family Ariidae. The genus Arius is distributed in brackish and fresh waters of Eastern Africa and south to Southeast Asia.
Cryptarius is a genus of catfishes of the family Ariidae. It includes two species, C. daugeti and C. truncatus. Cryptarius species originate from brackish waters of south and southeast Asia.
Potamarius is a genus of sea catfishes. The three species in this genus exclusively inhabit fresh water in southern Mexico and Guatemala. The individual species have relatively small ranges. The highly endangered Paragenidens grandoculis of Brazil was long classified in Potamarius, but a 2019 study has found it to belong in its own genus.
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.
Batrachocephalus mino, the beardless sea catfish, is the only species of catfish in the genus Batrachocephalus of the family Ariidae. This species occurs in marine and brackish waters of Bay of Bengal, and parts of the western central Pacific, in coastal waters, estuaries, and lower reaches of rivers. It is distributed from Pakistan, India, Sri Lanka, Bangladesh, Myanmar, Malaysia, Thailand, to Indonesia.
Ketengus typus, the bigmouth sea-catfish, is the only species in the sea catfish genus Ketengus.
Amphiarius phrygiatus, the Kukwari sea catfish, is a species of sea catfish which occurs in brackish estuaries with very low salinities, nearly entering freshwater, and is found on shallow muddy bottoms, ranging through Venezuela, Guyana, Suriname, French Guiana, and Brazil. It grows to about 30 centimetres (12 in) TL. As with other Arriid catfishes this species is a mouthbrooder. The female A. phrygiatus lays her eggs in a gelatinous mass on a sandy depression for the male to collect to mouthbrood. This species is caught for human consumption.
Cryptarius daugeti is a species of sea catfish from the Mekong River basin which inhabits large rivers. It is found in brackish and fresh waters of Cambodia and Vietnam. This species has a maximum length of 26 centimetres (10 in) TL.
Cryptarius truncatus, the spoonsnouted catfish, is a species of sea catfish from estuaries and lower courses of rivers from the Chao Phraya to Sumatra and Java, including the lower Mekong. It inhabits brackish waters of Thailand, Cambodia, Indonesia, and Malaysia. This species has a maximum length of 42 cm (17 in) in length. This fish species feeds on fishes and crustaceans. It is caught for human consumption.
Arius manillensis is a species of marine catfish endemic to the island of Luzon, Philippines. It is commonly known as the sea catfish, Manila sea catfish or kanduli. It is fished commercially.
Cathorops arenatus, the yellow sea catfish, is a species of sea catfish. It is found in the western Atlantic from the Gulf of Paria in Venezuela to Maranhão in Brazil. Maximum recorded body length is 25 cm.
Cathorops belizensis, the Belize sea catfish, is a species of sea catfish. It is found in mangrove channels in Belize City. Maximum recorded body length is 32 cm.
Cathorops higuchii, the Higuchi's sea catfish, is a species of sea catfish. It is named after Horácio Higuchi, a scientist from Museu Paraense Emílio Goeldi, Brazil. The species is found in estuaries and coastal waters of the western Atlantic from eastern Honduras to Colón, Panama. Maximum recorded body length is 35 cm.
The Thomas sea 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 mud on the floors of brackish and marine waters between the Gulf of Venezuela and the Amazon River, at a depth range of 1 to 20 m. It reaches a maximum total length of 63 cm (25 in), more commonly reaching a TL of 40 cm (16 in).
The Pemecou sea catfish, also known as the flapnose sea catfish, the mud cuirass, or the gillbacker, is a species of catfish in the family Ariidae. It was described by Marcus Elieser Bloch in 1794, originally under the genus Silurus. It inhabits marine, brackish and freshwaters in Brazil, Guyana, French Guiana, Colombia, Suriname, Venezuela, and Trinidad and Tobago. It dwells at a depth range of 1 to 5 m. It reaches a maximum total length of 94.2 cm (37.1 in), while males more commonly reach a TL of 30 cm (12 in) and females reach a TL of 62.5 cm (24.6 in). It reaches a maximum weight of 1.5 kg (3.3 lb).
