Schizopygopsis labiosa is a species of cyprinid fish that is only found in the upper reaches of the Yellow River basin in the Qinghai–Tibet Plateau of China, where it mostly inhabits slow-flowing cold waters at altitudes above 3,000 m (9,800 ft).[1] It was regarded as the only member of the genus Chaunchia, and as a schizothoracine (snowtrout and allies).[2][3][4] However, Eschmeyer's Catalog of Fishes classifies this species within the genus Schizopygopsis in the subfamily Schizopygopsinae.[5]
Schizopygopsis labiosa reaches up to 25 cm (10 in) in length.[1] Its lower jaw has a horny sheath, which it uses to scrape invertebrates and algae off the bottom.[6] It has seriously declined because of habitat loss, overfishing and introduced species, and is now listed as vulnerable on China's Red List.[6]
