ปลาตะพัดสีนาก | Scleropages inscriptus | Inscribed Asian Arowana
A new fish species from the Tananthayi or Tenasserim River basin, Malay Peninsula of Myanmar (Osteoglossidae: Osteoglossiformes)
[Ichthology • 2012]
Scleropages inscriptus, a new species of bony-tongue fishes, is described from the Tenasserim or Tananthayi River basin on the Indian Ocean coast of peninsular Myanmar. It differs from the previously known Southeast Asian and Australian members of the genus in having the bones of the circumorbital and opercular series and all or most of the scales on the sides of the body densely covered with complex maze-like markings. In morphology and in meristic and morphometric characters it is closer to the other Asian species of Scleropages, S. formosus, than to S. leichhardti or S. jardinii, the two species currently recognized from the Australian Region; it is therefore referred to the subgenus Delsmania Fowler 1934 (type species S. formosus)…

Arowanas are popular, especially in Asian areas, for their resemblance to the Chinese dragon. These freshwater fish are notorious for the high prices they fetch - ‘perfect’ specimens can sell for many thousands of dollars.
Freshwaterbony fish of the family Osteoglossidae, also known as bonytongues.In this family of fishes, the head is bony and the elongate body is covered by large, heavy scales, with a mosaic pattern of canals.
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 fish can obtain oxygen from air by sucking it into the swim bladder, which is lined with capillaries like lung tissue. The arowana is an “obligatory air breather”.
They are excellent jumpers; it has been reported that Osteoglossum species have been seen leaping more than 6 feet (almost 2 metres) from the water surface to pick off insects and birds from overhanging branches in South America, hence the nickname “water monkeys”.
