Diagnostic Description
provided by Fishbase
Body moderately compressed, belly with distinct keel of scutes. Lower jaw steeply rising within mouth; no teeth present at front of jaws; upper jaw with a distinct notch. The only other shad of the Gulf of Mexico has only 20 to 24 gill rakers. Closely resembles A. aestivalis and A. pseudoharengus of Atlantic coasts, but in them the lower jaw rises very steeply in the mouth (Ref. 188).
