Features and Behaviors

The sicklefin chub has small eyes and a small mouth. Its fins are long and sickle-shaped. The pectoral fin is long enough to reach past the base of the pelvic fin. There is a small barbel in each corner of the mouth. The back and upper sides are yellow-brown. The lower sides and belly are silver-white. The lower lobe of the caudal fin is darker than the upper lobe. Adults range from about two and one-half to four and one-fourth inches in length. Teeth are present in the throat.

This species lives in the main channel of the Mississippi River where there is a strong current and turbid water. Some external taste buds are present. Its habits are not well known. Spawning probably occurs in spring.
