A gar is a fish common to Louisiana waters. It's a predator with a toothy mouth and a slender body. Here in Louisiana we call them Alligator Gar because they have a snout like our alligators. The fossil record goes back to the early Cretaceous period. They're living fossils and have been living in our waters for lots of years.
When we catch an alligator gar, we do one of two things with it. 1) cut its head off and throw it back to feed the smaller fishes that it has been feeding on, or 2) make gar balls out of it. Back when I lived on Bayou Derbonne, there was a cook down the road, Ginger, who made gar balls once or twice a year. She'd call us and tell us to come down to the house. We'd bring something to add to the feast, load the ice chest with beer and soft drinks (for the kids), and head toward Ginger's house, where we'd eat gar balls, tell lies, and hang out under the pecan trees.
I tell you all this, because while we were in Missouri and stopped by Bass Pro Shops, we saw an aquarium with an alligator gar in it. Milady asked me to snap a picture, so I did.
Ginger cooked him into gar balls, ad he fed about thirty people, with all the fixings (taters, hush puppies and salad.) I don't care if I never catch another gar.
