Espinas dorsales (total) : 0; Espinas anales: 0. Head large; eyes large; snout moderately pointed, its anterolateral margin incompletely supported by bone. Head ridges rather weakly scaled, other head scales mostly without spinules; the dorsal and ventral snout surfaces mostly naked. Spines on lower jaw and pectoral girdle without spinules. Light organ large, lens-shaped black fossa between the pelvic fin bases. Swim bladder oval, with 6 to 11 short retia mirabilia and gas glands. Pyloric caeca 10 to 14. Overall color is light brown to swarthy, somewhat silvery ventrally, with heavy punctuations; mouth pale, blackish along tongue base; gill cavity blackish, paler with punctuations toward inner surfaces.
Body shape (shape guide): elongated; Cross section: circular.
Juveniles are bathypelagic (Ref. 9315). Feeds mainly on copepods and other small crustaceans, but not exclusively bottom-dwelling invertebrates (Ref. 9315).
