The blackchin shiner (Notropis heterodon) is an abundant North American species of freshwater fish from the family Cyprinidae. Described by Edward Drinker Cope in 1865, it is not a well-known species. It is a close relative of the blacknose shiner. Chiefly occurring now in the Great Lakes and occasionally in upper Mississippi River drainages, the blackchin once ranged commonly as far south as Illinois and Ohio. This fish resides over sandy bottoms in cool waters that provide a lot of cover for the small minnow. Omnivorous, it eats worms and small arthropods as well as plant material. Blackchin shiners are unique because of their anatomical features, such as the black coloring, the incomplete lateral line, and a distinctive dental arrangement.
