The Asian arowana (Scleropages formosus) comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. [3] While most consider the different varieties to belong to a single species, [4] [5] [6] [3] [7] work by Pouyaud et al. (2003) [8] differentiates these varieties into multiple species.
In 1993, Pangasius was one of two extant genera (along with Helicophagus) in the family Pangasiidae.At this point, it was split into four subgenera. Pangasius (Pangasianodon) included P. gigas and P. hypophthalmus and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single-lobed swimbladder.
