Ammocrypta beanii
About This Fish

The Naked Sand Darter is a fairly widespread species found in lowland rivers and larger streams of Mississippi and Gulf Coast drainages in northeast Louisiana, Mississippi, and western Tennessee to western and central Alabama. All sand darters are translucent, so they blend in with the sand substrate they live upon. Naked Sand Darters have a very long breeding season, from March to October, whereas most darters only spawn in the spring They get their common name from lacking body scales except along the lateral line and on the caudal peduncle (region just before the caudal fin).
