Thymallus yaluensis, also known as Yalu grayling, is a putative species of freshwater ray-finned fish from the genus Thymallus (graylings) in the family Salmonidae. It is endemic to the upper Yalu River on the China-North Korea border.[1]
Description
Thymallus yaluensis is a small fish, the maximum recorded length is {[cvt|20|cm}}.[1] "It has the most beautiful form and fins of a freshwater fish" in Korea.[1]
Taxonomy dispute
Some confusion exists about the identity of T. yaluensis, as it is very similar in form to the Arctic grayling (Thymallus arcticus), and has mostly been treated as a subspecies T. a. yaluensis,[2] although FishBase treats it as an independent species.[1] According to mitochondrial DNA, T. yaluensis is, however, inseparable from the Amur grayling (Thymallus grubii), and was suggested to be a junior synonym of that.[3] 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.[citation needed]
