any of several species of deep-sea, marine fishes constituting the family Trachipteridae (order Lampridiformes). The family contains three genera: Trachipteras, Desmodema, and Zu. These slender-bodied fishes occur in all the major oceans. The name ribbonfish comes from the long, stringlike dorsal fin that originates behind the head and waves like a ribbon as the fish swims. Ribbonfishes are further distinguished by their upward-pointing caudal fins and lack of anal fins. The largest of the ribbonfishes, T. arcticus, reaches a length of 2 m (6.5 feet) and is found in cold northern waters
