Scleropages formosus(Asian Arowana)
An Ancient Lineage of Bony-Tongue Fishes
The Asian arowana belongs to the order Osteoglossiformes and 
the family Osteoglossidae. It inhabits tropical freshwater 
environments in Southeast Asia, including rivers, lakes, and 
swamps. Its elongate body is covered with large, lustrous scales. 
The mouth is upturned, and a pair of barbels is present at the tip 
of the lower jaw. It feeds on fishes, insects and other small 
animals. Bony-tongue fishes represent an ancient lineage of 
ray-finned fishes that first appeared during the Mesozoic and 
retain several morphological features of early bony fishes. Living 
bony-tongue fishes provide important comparative material for 
understanding the morphology and ecology of early-diverging 
teleost lineages.
