Waryfishes are deep-sea aulopiform fishes in the small family Notosudidae. They are thought to have a circumglobal distribution in subarctic to subantarctic waters. The family name Notosudidae derives from the Greek noton (back) and Latin sudis (a fish, esox, the name of salmon). Description Waryfishes are slender, scaled fish, similar in appearance to lancetfishes, but lacking the greatly enlarged dorsal fin. Although the adults are deep-water fish, the larvae inhabit surface waters, and are unique in having teeth on their upper jaws. Waryfishes lack a swim bladder. Dorsal fin: 9-14 rays Anal fin: 16-21 rays Pectoral fin: 10-15 rays Scales in lateral line: 44-65 References Aulopiformes Ray-finned fish families
