(subclass Actinopterygii, order Perciformes)
A small family of primarily marine fish that have an eel-like body, large eyes, a low-slung mouth, and rather reduced pelvic fins. The very long dorsal fin starts anterior to the pectoral fins. Both dorsal and anal fins are confluent with the tail fin. There are about three species, found in tropical Australia.
