Osteoglossiformes
Osteoglossiformes (Greek: "bony tongues") is a relatively primitive 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 osteoglossiforms was described from the Danish Eocene Fur Formation dramatically increases 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, Hiodontiformes. Members of the order are notable ...

Arapaimidae
Arapaiminae is a subfamily of freshwater osteoglossiform (bony-tongued) fishes belonging to the family Osteoglossidae. It includes the South American arapaimas of the Amazon Basin, Amazon and Essequibo River, Essequibo basins and the African arowana, African arowana (''Heterotis niloticus'') from the watersheds of the Sahel, Sahelo-Sudanese region, Senegal, The Gambia, Gambia, and parts of Eastern Africa. This subfamily is sometimes raised to the rank of family, as Arapaimidae. A commonly used synonym is Heterotidinae, but according to the ICZN, Arapaiminae has priority. Arapaimines, along with other osteoglossomorphs, are of Phylogenetics, phylogenetic and evolutionary interest due to their trans-oceanic distribution, excellent fossil record, and position as one of the oldest living teleost lineages. The type-species of the group, ''Arapaima gigas'', is an important South American food source and charismatic representative of the region. Both ''Arapaima'' and ''Heterotis'' are c ...

Osteoglossidae
Osteoglossidae is a family of large freshwater fish, which includes the arowanas and arapaima. The family contains two subfamilies Arapaiminae and Osteoglossinae, with a total of five living genera. Osteoglossids are basal teleosts that originated some time during the Cretaceous, and are placed in the actinopterygiid order Osteoglossiformes. As traditionally defined, the family includes several extant species from South America, one from Africa, one from Asia, and two from Australia Australia, officially the Commonwealth of Australia, is a Sovereign state, sovereign country comprising the mainland of the Australia (continent), Australian continent, the island of Tasmania, and numerous List of islands of Australia, sma ....

Freshwater Butterflyfish
The freshwater butterflyfish or African butterflyfish, ''Pantodon buchholzi'', is the only extant species in the family Pantodontidae within the order Osteoglossiformes. It is not closely related to saltwater butterflyfishes. Description and habits Freshwater butterfly fish are small, no more than in length, with very large pectoral fins. It has a large and well-vascularized swim bladder, enabling it to breathe air at the surface of the water. It is carnivorous, feeding primarily on aquatic insects and smaller fishes. The freshwater butterflyfish is a specialized surface hunter. Its eyes are constantly trained to the surface and its upturned mouth is specifically adapted to capture small prey along the water's surface. If enough speed is built up in the water, a butterflyfish can jump and glide a small distance above the surface to avoid predation. It also wiggles its pectoral fins as it glides, with the help of specialized, enlarged pectoral muscles, the ability which earned t ...

Arowana
Arowanas are freshwater bony fish of the subfamily Osteoglossinae, also known as bony tongues (the latter name is now often reserved for Arapaiminae). In this family of fish, the head is bony and the elongated body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and anal fins have soft rays and are long based, while the pectoral and ventral fins are small. The name "bonytongues" is derived from a toothed bone on the floor of the mouth, the "tongue", equipped with teeth that bite against teeth on the roof of the mouth. The arowana is a facultative air breather and can obtain oxygen from air by sucking it into its swim bladder, which is lined with capillaries like lung tissue. Evolution Within Osteoglossinae, the South America ''Osteoglossum'' arowanas diverged from the Asian and Australian ''Scleropages'' arowanas about 170 Mya, during the Middle Jurassic. The Osteoglossidae are the only exclusively freshwater fish family found on both sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonytongue
Arapaiminae is a subfamily of freshwater osteoglossiform (bony-tongued) fishes belonging to the family Osteoglossidae. It includes the South American arapaimas of the Amazon and Essequibo basins and the African arowana (''Heterotis niloticus'') from the watersheds of the Sahelo-Sudanese region, Senegal, Gambia, and parts of Eastern Africa.

Both ''Arapaima'' and ''Heterotis'' are cultured for food in their respective countries due to their heartiness and meat ...
