The second largest freshwater fish in North America, the alligator gar is second in size only to the white sturgeon. Reaching weights of up to 300 pounds, the alligator gar can stretch to lengths over nine feet. Historically, the alligator gar's home range included the Mississippi River and its tributaries from the lower reaches of the Ohio and the Missouri rivers southward to the Gulf of Mexico. Today the range is significantly smaller. The fish are primarily restricted to coastal rivers, with inland populations persisting not only in Oklahoma, but also in Florida, Georgia, Alabama, Tennessee, Arkansas, and Texas.
