الأشعة الظهرية الناعمة (المجموع) : 16 - 17; أشعه شرجية لينه: 13; فقرات: 50 - 51. Moderately elongate and slender. Slightly depressed anteriorly and compressed posteriorly. Color generally white, with peritoneum, branchial and buccal regions dark. Small specimens have faint vertical bars (Ref. 37039).
Benthic (Ref. 58302). Found on the continental rise and the abyss, commonly below 2,000 m, in water colder than 4°C. Larvae are probably pelagic in near-surface midwaters. Solitary, lurking bottom feeder. Probably piscivore (Ref. 4964).
