Two species of Scleropages occur in Australian waters. One is the Gulf saratoga and the second is the spotted-barramundi (S. leichardti). Impressive in body length, the Gulf saratoga is laterally compressed, with a large upturned mouth, big scales, and barbels on the lower lip. These freshwater fishes have large, wing-like pectoral fins. Several reddish or pinkish spots are arranged in a crescent shape around the trailing edge of the scale, giving it a pearly appearance. It can be distinguished by the relatively straight dorsal profile and lower dorsal. This fish has its distribution in parts of Australia like the Northern Territory, Northern Queensland, the Adelaide River, and also in parts of Papua New Guinea and Indonesia.
