Southern Sand Darter (Ammocrypta meridiana)

The Southern Sand Darter is restricted to Coastal Plain rivers and larger streams in the Mobile Basin in Mississippi and Alabama. All Sand Darters are translucent, so they blend in with the sand substrate they live upon. The Southern Sand Darter lives in the same habitat as the Naked Sand Darter (A. beanii), but they are fairly easy to tell apart. The body of the Southern Sand Darter is completely covered in scales, whereas the Naked Sand Darter lacks body scales except along the lateral line and on the caudal peduncle (region just before the caudal fin).

Scaly Sand Darter (Ammocrypta vivax)

The Scaly Sand Darter is found primarily in Coastal Plain creeks and small rivers from eastern Texas and Oklahoma to Mississippi, western Tennessee, and a small part of southwest Alabama. There are only two records for this species in the Tennessee River Drainage. All Sand Darters are translucent, so they blend in with the sand substrate they live upon. The Scaly Sand Darter has vertical dark green blotches along its side.

Naked Sand Darter (Ammocrypta beanii)

The Naked Sand Darter is a fairly widespread species found in Coastal Plain rivers and larger streams from 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).
