Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 14 - 18; Anale stekels: 0; Anale zachte stralen: 19 - 22; Wervels: 79 - 82. Jet black all over except for the dark gray on the posterior part of the lower jaw; when the thin epidermis is rubbed off, as is difficult to avoid, the dermis shows lead gray; young rich brown in color (Ref. 6885).
Body shape (shape guide): eel-like.
Mesopelagic migrating into epipelagic at night (Ref. 35904). Oviparous, with planktonic eggs and larvae (Ref. 35904).
