Short Description from U.S. Fish & Wildlife Service:
The Peppered Chub (Macrhybopsis tetranema) is a small minnow with a fusiform body shape, which means that it is tapering at both ends, which rapidly tapers to a conical head. Mouth position is inferior and horizontal, with two distinct pairs of barbels present. Taste buds are present over most of the body. Adults attain a maximum length of 3 inches. Although somewhat variable, there are eight fin rays typically present in the dorsal, anal and pelvic fin. Anal and dorsal fins are slightly falcate, meaning that they are curved or hooked. Peppered chub have rounded pelvic fins and pectoral fins that are long, falcate and just reach the bases of the pelvic fins in adult males. Adult females have shorter and pointed pectoral fins, usually not reaching the pelvic fin bases. This species also has two to 10 pectoral rays that are greatly thickened in large nuptial males, and bear rows of small, conical, antrorse, meaning that they point forward, tubercles. Basal parts of rays bear one to two rows of tubercles. Females are without tubercles.
Natural Habitat:
Slow-moving, sandy-bottomed main channel rivers.
