Ozark chub

The Ozark chub (Erimystax harryi) is a species of ray-finned fish in the family Cyprinidae. It is found in medium-gradient streams in the Ozarks in Missouri and Arkansas. A petition for federal protection under the Endangered Species Act was rejected by the U.S. Fish and Wildlife Service in 2019 due to the species' continued presence in most of the waterways it is historically known from.
