Rostral spine well developed with vertical basal component which projects dorsally, and a long forward projecting straight component; peritoneum and guts black; narrow weak band of basibranchial teeth; bones thin, weakly developed (Ref. 34024). Branchiostegal rays: 7 (Ref. 36413).

Adults are found on soft bottoms, between 429 and 732 m in depth, while juveniles are encountered at shallower depths (Ref. 9329). Prejuveniles mesopelagic (Ref. 34024). Oviparous, with planktonic larvae and extended pelagic juvenile stage (Ref. 36413). Oval pelagic eggs float in a gelatinous mass (Ref. 205).
