The Altamaha shiner (Cyprinella xaenura) is a species of fish in the family Cyprinidae.

[2][3] Physical characteristics of the Altamaha shiner include a pointed snout and a terminal or slightly sub-terminal mouth.

[2] Coloration includes a dusky olive upper portion of the body, a dark streak along the back, and a silver-black stripe on the rear half of the body which is often spread into a distinct spot on the base of the caudal fin.

[citation needed] Degradation of stream quality is also a major threat to the Altamaha shiner.

[4] Excess sedimentation can disturb or destroy eggs which are laid in crevices or small cracks within rocks.
