Approximately 18" long, broad head, few spots near back of body.
Distinguished from Spotted Gar by range
Two foot gar, what species? Don't worry, it was released afterwards.
Between 24-30 inches long. Olive green with back spots. It looked more like a spotted gar to me but that doesn't make sense in the Potomac River.
In American English, the name gar (or garpike) is strictly applied to members of the Lepisosteidae, a family including seven living species of fish in two genera that inhabit fresh, brackish, and occasionally marine, waters of eastern North America, Central America, and the Caribbean islands.
