Shortnose gar have a prehistoric-looking appearance.

Shortnose gar vary in color, changing from brown/olive green on the dorsal surface to yellow on the sides and white on the underbelly. Shortnose gar can be discerned from other gar species in that they lack the upper jaw of the alligator gar, the long snout of the longnose gar, and the markings of the spotted gar.〔(Shortnose Gar - Montana Field Guide. )〕 The shortnose gar reaches up to , but a more common length is .
