It is the largest North-American ranid. In its natural range, adults can reached at most a 184 mm snout-vent length (Louisiana), while in Europe (southwestern France), adults may exceed a 195 mm snout-vent length, with an average weight of approximately 430 grams. It is likely to feed on a wide range of prey: amphibians, fishes, small mammals, ducklings and small bird species, molluscs, crustaceans and insects. In southwestern France, the adult diet consists of a wide range of prey, with amphibians and insects most prominent.
