Central Asian Sturgeons
Pseudoscaphirhynchus
Pseudoscaphirhynchus is a genus of relatively small, highly threatened sturgeons that are restricted to the Aral Sea system (although extirpated from the Aral Sea itself), including the Amu Darya and Syr Darya river basins, in Central Asia.
P. fedtschenkoi is restricted to Syr Darya, but has not been seen in decades and it is possibly extinct. The two other species in the genus are restricted to Amu Darya: P. hermanni survives in very low numbers and P. kaufmanni in low numbers, with both being rated as Critically Endangered by the IUCN.
