Family: Lepisosteidae - Gars are covered with diamond-shaped scales that do not overlap. They have long, strongly toothed jaws developed into a beak. The body is cylindrical, and the caudal fin is rounded. Gars are often found in sluggish waters of rivers and lakes. The gas bladder is connected to the throat and does function in breathing to supplement the gills, allowing these fishes to live in oxygen poor waters. Gars are predators of other fishes.
