Cahaba Shiner (Notropis cahabae)

The Cahaba Shiner is only found in two rivers in central Alabama, the Cahaba River and the Locust Fork. This federally endangered species resides in backwaters adjacent to shoals and riffles on the mainstem of these rivers, only occasionally entering the lower reaches of tributaries. This species is found in similar habitats as the common Mimic Shiner (N. volucellus), and they are very difficult to tell apart.

Mimic Shiner (Notropis volucellus)

The Mimic Shiner is a widespread and common species found across eastern North America, including the Mobile Basin, Tennessee, and Cumberland river drainages. This is a species complex containing multiple undescribed species. Mimic Shiners inhabits backwaters in rivers, creeks, and lakes. The distinguishing character for Mimic Shiners (and other species in the Mimic Shiner species group) are lateral-line scales on the front half of the body that are twice as tall as they are wide.

Tallapoosa Shiner (Cyprinella gibbsi)

The Tallapoosa Shiner is native to the Tallapoosa River System where it is most common minnow in tributaries where it occurs. Like other members of its genus, Tallapoosa Shiners have diamond-shaped scales and spawn in crevices. They can be distinguished from the similar Tricolor Shiner (C. trichroistia) by the pattern of the tubercles, horny projections used in spawning, on the head of breeding males.
