basa fish, P. bocourti.[1]

Taxonomy

In 1993, Pangasius was one of two extant genera (along with

swimbladder. Pangasius (Pteropangasius) included P. micronema and P. pleurotaenia and was typified by four lobes in the swimbladder and with multiple segments in the last lobe. Pangasius (Neopangasius) included P. nieuwenhuisii, P. humeralis, P. lithostoma, P. kinabatanganensis, and typically had palatal teeth arranged in a single large patch and high vertebral counts. Pangasius (Pangasius) was the final subgenus and had no unique features, including the remaining species.[2] These subgeneric classifications were confirmed in 2000 except for Neopangasius, found to be polyphyletic and to be part of Pangasius (Pangasius), thus leaving three subgenera.[2]

Since then, the subgenera have been variably recognized as separate. P. gigas and P. hypophthalmus have been classified in the genus Pangasianodon, and P. micronemus and P. pleurotaenia in the genus Pseudolais (with Pteropangasius as a junior synonym).[3]

In 2011, Pangasius was sixth in the
