The flathead chub is a slender, silvery minnow with small eyes, sickle-shaped pectoral fins, and wedge-shaped head with a pointed snout. Native to Missouri's big rivers and their tributaries, it is now state endangered.

The southern redbelly dace has two dusky stripes separated by a broad golden stripe along the side. The bellies of males turn brilliant red in spring. It lives in small creeks and spring branches of the Ozarks with permanent flow of cool, clear water and a gravel or sand bottom.

The spring cavefish is the only cavefish in our state that has eyes, however small, and whose body is yellowish brown or brown; our other cavefishes lack eyes entirely and are pale and nearly colorless.

The central stoneroller is a brownish minnow with small eyes. The lower jaw has a flat, shelflike extension used to scrape algae from rocks. Found statewide, it is most active during the daytime.

The northern studfish is common and widely distributed in every principal Ozark stream system except the Neosho. Males in spawning coloration are some of our prettiest topminnows.

In our state, the duskystripe shiner is only found in the White River system of southwest and south-central Missouri. It prefers swift, clear headwater streams. The dark stripe along the side extends from nose to tail with a lighter-colored band above it.
