Thymallus yaluensis
''Thymallus yaluensis'' is a putative species of freshwater fish, a grayling in the salmon family Salmonidae. It is endemic to the upper Yalu River in Korea, on the Chinese border.〔
''Thymallus yaluensis'' is a small fish, the maximum recorded length is 20 cm (8 in).〔 "It has the most beautiful form and fins of a freshwater fish" in Korea.〔
There is some confusion about the identity of ''T. yaluensis.'' It is very similar in form to the Arctic grayling ''T. arcticus'', and has mostly been treated as a subspecies, ''T. a. yaluensis'',〔Eschmeyer W (2015) (''yaluensis, Thymallus'' ) Catalog of Fishes, California Academy of Sciences.〕 although FishBase treats it as an independent species. According to mitochondrial DNA, it is however inseparable from the Amur grayling ''T. grubii'', and was suggested to be a junior synonym of that.〔MA Bo, HUO Tang-Bin, JIANG Zuo-Fa (2008) (''Thymallus arcticus yaluensis'' is a synonym of ''T. grubii'' by mitochondrial control region sequences analysis. ) Acta Zootaxonomica Sinica 33 (2)〕
Confusingly it has also been reported from widely separate regions including Siberia, the Alps in Europe, and the northern Mississippi River drainage in North America.
