Callichthys serralabium is a tropical freshwater fish belonging to the Callichthyinae sub-family of the family Callichthyidae.
It was originally described by Lehmann & Reis in 2004. The species name serralabium comes from the presence of a serrated lower lip in this species, which differentiates it from other members of this genus. [1]
It originates in inland waters in South America, and is found in the upper Orinoco River and lower Rio Negro basins of the Amazon River drainage in Venezuela and Brazil. [1]
C. serralabium can be distinguished from the other species of Callichthys by having the lower lip serrated (it is smooth in all other species). It also has 8–9 branched rays in the pectoral fin (instead of 6–7) and an irregular color pattern of dark, diffuse blotches on flanks of adults. [1] The fish will grow in length up to 15.8 centimetres (6.2 in) SL. [1]
The body is elongated and moderately depressed anteriorly; the trunk and caudal peduncle are progressively more compressed towards the caudal fin. The body profile between snout and dorsal-fin origin straight to slightly convex. The snout is rounded or roughly triangular in dorsal view. The mouth is slightly inferior (pointed downwards). [1]
The dorsal fin and pectoral fins have one spine. The pectoral fin spine has stronger odontodes anteriorly and small retrorse hooks posteriorly. The pectoral spine of fully developed nuptial males is elongated and thick. The pelvic fins and caudal fin are rounded. The adipose fin has a pointed, depressible spine. [1]
Callichthyidae is a family of catfishes, called armored catfishes due to the two rows of bony plates along the lengths of their bodies. It contains some of the most popular freshwater aquarium fish, such as many species in the genus Corydoras.
The stream catfishes comprise the family Akysidae of catfishes.

Callichthys is a small genus of freshwater catfish in the Callichthyinae subfamily of the armored catfish family, and consists of 4 species from South America. The genus Callichthys is distributed in most freshwater drainages of South America.
Callichthys callichthys, the cascarudo, armored catfish, bubblenest catfish, hassar, or mailed catfish, is a subtropical freshwater fish belonging to the subfamily Callichthyinae of the family Callichthyidae.
The blackspot shark is a small species of requiem shark in the family Carcharhinidae found in the tropical Indo-West Pacific Ocean between latitudes 24°N and 30°S, from the surface to a depth around 40 m (130 ft). Its length is a little under one meter (yard) and it is not considered to be dangerous to humans. It feeds mainly on fish, crustaceans, and squid. This shark is also caught in small-scale fisheries for human consumption.
Callichthys fabricioi is a tropical freshwater fish belonging to the Callichthyinae sub-family of the family Callichthyidae. The fish will grow in length up to 12.5 centimetres (5 in) SL. C. fabricioi is found in the trans-Andean upper Cauca River in the Magdalena River basin of Colombia. Although described in 1999, two other cogener fish have since been discovered.
Lasiancistrus is a genus of suckermouth armored catfishes. They are native to South America and Panama.
Pseudolithoxus is a genus of suckermouth armored catfishes with five described species from the basins of the Orinoco, Casiquiare and upper Rio Negro in Venezuela. Additionally, a possibly undescribed species is known from the Trombetas and Nhamundá rivers in Brazil.
Magosternarchus is a genus of weakly electric knifefish in the family Apteronotidae, containing two species. They are endemic to Brazil, occurring in large river channels in the Amazon River basin. Both species are unusual benthic predators that specialize in biting off the tails of other knifefishes, and are characterized by their greatly enlarged jaws and teeth. Recent systematic studies indicate that both species should be included in Sternarchella instead of being placed in their own genus.
Cephalopholis fulva, the coney or the butterfish, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is found in the western Atlantic. It is associated with reefs and is a quarry species for commercial and recreational fisheries. It can be found in the aquarium trade.
Synodontis longirostris, known as the eyespot synodontis, is a species of upside-down catfish that is native to the Democratic Republic of the Congo where it occurs in the Congo Basin. It was first described by British-Belgian zoologist George Albert Boulenger in 1902, from specimens obtained in the Ubangi River at Banzyville. The species name longirostris comes from the Latin word longus, meaning "long", and the Latin word rostrum, meaning snout, referring to the long snout on this species.
Cirrhibarbis capensis, the barbelled klipfish, is a species of clinid found in subtropical waters of the Atlantic Ocean around South Africa. This species can reach a maximum length of 36 centimetres (14 in) TL. This species preys primarily on benthic crustaceans, mostly amphipods and isopods. It is currently the only known member of its genus.
Blennophis anguillaris, the snaky klipfish, is a species of clinid found in the subtropical waters of the Atlantic Ocean around South Africa. It can be found in the subtidal zone and also is a denizen of tidepools. This species can reach a maximum length of 30 centimetres (12 in) TL.
Blennophis striatus, the Striped klipfish, is a species of clinid found in the subtropical waters of the Atlantic Ocean from Saldanha Bay to East London, South Africa where it can be found in the subtidal zone as well as inhabiting tidepools. This species can reach a maximum length of 17.5 centimetres (6.9 in) TL.
Clinus brevicristatus, the Cape klipfish, is a species of clinid that occurs in subtropical waters of the Atlantic Ocean around South Africa where it prefers habitats with plentiful growth of seaweed. This species can reach a maximum length of 12 centimetres (4.7 in) TL.
Astyanax microschemos is a species of characid fish from Brazil. It belongs to the A. scabripinnis species complex and differs from other species outside it by having a lower number of branched anal fin rays and its shallow body depth being about 26.9-29.7 vs more than 35% of its standard length (SL). Compared to species of its own complex, it can be distinguished by the combination of its shallow body depth, and smaller interorbital width. The species name comes from the Greek mikroschemos, meaning "low stature", which refers to the shallow body depth of the animal.
Astyanax pelecus is a species of characid fish from Brazil. It can be distinguished from its cogenerate species by: its body depth ; its short and pointed snout smaller than the orbital diameter; and a reduced number of branched anal fin rays. A. pelecus also differs from members of its genus by its characteristic color pattern. It possesses a single humeral spot that is constricted to the region above the lateral line; at the same time it shows a conspicuous midlateral body stripe from opercle to the caudal fin base, an autapomorphy of this precise species. Most other Astyanax species have a humeral spot that is vertically or horizontally elongate and have the midlateral stripe becoming faint near that humeral spot. The species name is derived from the Greek pelekus, meaning "axe", referring to the pigmentation shape resulting from the adjoinment of the humeral spot with the midlateral stripe.
Huigobio exilicauda is a species of cyprinid fish found in the Pearl River basin in China. All of the specimens were collected in the Pearl River basin in Guangdong Province, China, in 1976. It is sometimes considered an ambiguous synonym of Huigobio chenhsienensis. Differs from Huigobio chenhsienensis in that it has a thin caudal peduncle ; and a narrower interorbital gap than eye.
Gobiomorphus coxii, or Cox's gudgeon, is a species of sleeper goby in the family Eleotridae which is native to the upland rivers of south eastern Australia.
