The Amber Darter is a federally endangered species found in a few populations in the Coosa River System in Georgia and Tennessee. They live over gravel and sandy substrates in fast-moving water of small to medium rivers. As the common name suggests, Amber Darters have golden coloration with dark saddles along their back. 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.
