Goldline Darter (Percina aurolineata)

Description: 

The Goldline Darter is a federally threatened species found in the Coosa and Cahaba river systems of the Mobile Basin in Alabama and Georgia. They live in rocky runs and riffles of medium rivers. As the common name suggests, Goldline Darters have a gold stripe along their upper side with black blotches below. While most darters are found on stream bottoms, members of the genus Percina tend to be found higher in the water column because they retain a swim bladder.
