The Okefenokee Swamp, located in southeastern Georgia and northern Florida, is the largest freshwater wetland in the United States. In this illustrated guide to the fishes of the swamp, the authors provide descriptions and drawings of thirty-six species, ranging from the American eel to the speckled madtom, chain pickerel, and blackbanded darter. For each fish, the authors include latin, common and variant names and discuss differences from similar species, local habitats and feeding and mating patterns.
