Notopteridae
The family Notopteridae contains 11 species of osteoglossiform (bony-tongued) fishes, commonly known as featherbacks and knifefishes. These fishes live in freshwater or brackish environments in Africa and West, South, East and Southeast Asia. With the denotation of "knifefish", the notopterids should not be confused with Gymnotiformes, the electric knifefishes from South and Central America. Although their manner of swimming is similar and they are superficially similar in appearance, the two groups are not closely related. A few of the larger species, especially ''Chitala ornata'', are food fish and occasionally aquarium pets. The name is from Greek ''noton'' meaning "back" and ''pteron'' meaning "fin". Fossils The earliest fossil of this family is otolith of '' Notopteridarum'' from the Late Cretaceous of India, about 70.6 to 66 million years ago. Description Featherbacks have slender, elongated, bodies, giving them a knife-like appearance. The caudal fin is small and fus ...

Osteoglossiform
Osteoglossiformes , meaning "bony tongues" in Ancient Greek, is a relatively primitive order (biology), order of ray-finned fish that contains two sub-orders, the Osteoglossoidei and the Notopteroidei. All of at least 245 living species inhabit freshwater. They are found in South America, Africa, Australia and southern Asia, having first evolved in Gondwana before that continent broke up. In 2008, several new species of marine life, marine osteoglossiforms were described from the Danish Eocene Fur Formation, dramatically increasing the diversity of this group. This implies that the Osteoglossomorpha is not a primary freshwater fish group with the osteoglossiforms having a typical Gondwana distribution. The Gymnarchidae (the only species being ''Gymnarchus niloticus'', the African knifefish) and the Mormyridae are weakly electric fish able to sense their prey using electric fields. The mooneyes (Hiodontidae) are often classified here, but may also be placed in a separate order, Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chitala
''Chitala'' is a genus of fish of the family Notopteridae. This genus contains six species, some of which are important in aquaculture and the aquarium industry. They are commonly known as the Asian knifefishes or featherbacks. They are native to freshwater in South East and Southeast Asia. The largest fish in the genus (and also the family) is ''Chitala lopis'', which grows up to a length of . Other well-known species are the clown knifefish (''C. ornata'') and the Indochina knifefish (''C. blanci''). Species There are six recognized species in this genus. In the past some of these (notably ''C. ornata'') were included in ''C. chitala'',Roberts, T.R. (1992). ''Systematic revision of the old world freshwater fish family Notopteridae.'' Ichthyol. Explor.

Chitala Ornata
The clown featherback (''Chitala ornata''), also known as the clown knifefish and spotted knifefish, is a nocturnal species of tropical fish with a long, knife-like body. This knifefish is native to freshwater habitats in Cambodia, China, Hong Kong, Laos, Macau, Thailand, and Vietnam, but it has also been introduced to regions outside its native range. It is one of the world's most invasive species. It is often seen in aquaculture and the aquarium trade, where it is frequently confused with '' Chitala chitala''; the latter species is very rare in the aquarium trade.Seriously Fish: Chitala ornata.'

Xenomystus Nigri
The African brown knifefish (''Xenomystus nigri'') is the only species in the genus ''Xenomystus'' of the family Notopteridae. This fish is found in the Chad, Nile, Congo, Ogowe and Niger basins, as well as coastal river basins in Sierra Leone, Liberia, Togo, Benin and Cameroon. Anatomy and appearance This fish reaches 30 cm (12 in) in standard length. The body of these fish is unusual; it is ventrolaterally flattened and elongated, giving the appearance of a knife blade. The caudal and anal fins are fused and run from beneath the gill opening to the pointed end of the body, creating a uniform, skirt-like fin. This appendage gives the animal superior control in the water, as it is able to propel itself forward and backward with a minimum of wasted energy. The pelvic fins are extremely reduced and are not used in locomotion. The dorsal fin is absent. The pectoral fins of the African brown knifefish are lengthy and designed to give the animal precise control as it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Papyrocranus Afer
The reticulated knifefish (''Papyrocranus afer'') is a species of freshwater fish in the family Notopteridae, the featherbacks, found in tropical West Africa. It reaches a maximum length of and a reported weight of . Description The reticulated knifefish usually grows to a length of about . It is laterally flattened and has very small scales. Like other featherbacks, the dorsal fin projects from its back rather like a feather; this fin has no spines and just two soft rays. The fish has an elongated anal fin with no spines and between 113 and 141 soft rays. This is united with the small caudal fin. There are no pelvic fins. The anal fin provides propulsion, either forwards or backwards, undulating from side to side with a rippling movement. Distribution This fish is native to tropical West Africa. It occurs in the Niger basin and other coastal river basins including the Tano River and Pra River basins in Ghana, and the Cross River and Sanaga River basins to the east of the Ni ...

Chitala Borneensis
The Indonesian featherback (''Chitala borneensis'') is a species of knifefish from freshwater habitats in Southeast Asia. The details of its range are not entirely clear, with FishBase reporting that it occurs in Sumatra, Borneo, and the Malay Peninsula,. In 2024, it was reported to have been found in the Mae Klong basin and the eastern coast of southern Thailand, while Catalog of Fishes considers it endemic to Borneo. There has been considerable taxonomic confusion between this species and '' C. lopis''; it was argued as recent as 1992 that the two are variants of a single species, but later authorities have recognized them as separate.Kottelat, M., and Lim, K.K.P.
