Arowana

Red Arowana ( Scleropages put three)

The osteoglossid family ( Osteoglossidae (Size: osteon = bone, glossa = tongue ) ) are generally large freshwater fish that live zirkumtropisch in tropical South America, Southeast Asia, New Guinea and northern Australia. The animals covered by their large shed, numerous primitive features and are predators or omnivores that can capture their prey, such as insects, in the jump.

Features

Osteoglossid be 90 centimeters to one meter long. They have an elongated, laterally flattened body. The mouth is large and is directed obliquely upwards. Lower jaw is two barbels. Along the lateral line organ they have 21-55 scales, the number of vertebrae is 60 to 100 The pelvic fins are supported by five to six fin rays and are far behind the pectoral fins. Your maxilla is dentate. The number of Branchiostegalstrahlen is from 10 to 17

Genera and species

There are two genera with seven and two kinds:

• Genus Scleropages Günther, 1864 Subgenus Dels Mania Golden Arowana ( Scleropages aureus) Pouyaud, Sudarto & Teugels, 2003
• Scleropages inscriptus Roberts, 2012
• Asian Forkbeard ( Scleropages formosus ) ( Schlegel & Müller, 1844)
• Red Arowana ( Scleropages put three) Pouyaud, Sudarto & Teugels, 2003
• Silver Arowana ( Scleropages macrocephalus) Pouyaud, Sudarto & Teugels, 2003

• Scleropages jardinii ( Saville -Kent, 1892)
• Leichhardt's osteoglossid ( Scleropages leichhardti ) ( Günther, 1864)

• Arowana ( Osteoglossum bicirrhosum ) ( Cuvier (ex Vandelli ), 1829)
• Black osteoglossid ( Osteoglossum ferrerai ) Kanazawa, 1966

The American ichthyologist Nelson, in his standard work on fish systematics, Fishes of the World and the butterfly fish ( Pantodon buchholzi ), the Arapaima ( Arapaima gigas) and the African osteoglossid ( Heterotis niloticus ) to the family. The last two then form the subfamily Heterotidinae that osteoglossid ieS the subfamily Osteoglossinae. In most other classifications is the butterfly fish, which probably occupies a basal position within the Knochenzünglerartigen, placed in a separate family, the Pantodontidae. Arapaima and African osteoglossid make up the family Arapaimidae which is combined with the Osteoglossidae to the subordination Osteoglossoidei.
