They have several other common names, including Asian bonytonguedragonfishand a number of names specific to the different color varieties.

At least three other species of the genus are recognised, two of which occur in Australia, and another which was described from Burma Myanmar in Roberts, The latter, Scleropages inscriptusis similar in form to Scleropages formosus but its head and body is adorned with complex markings in a maze-like pattern. The species occurs in blackwater habitats with acidic water such as swamps, wetlands and slow-flying rivers.
Mitochondrial DNA-derived sequences have become popular markers for evolutionary studies, as their comparison may yield significant insights into the evolution of both the organisms and their genomes. From the more than 24, teleost species, only complete mtDNA sequences are available GenBank status on 06 Sep In this paper, we report the complete mitochondrial genome sequence of Asian arowana, a basal bonytongue fish species, which belongs to the order of Osteoglossiformes.
