Scaly Sand Darter (Ammocrypta vivax)

Description: 

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.
