Raios dorsais (total) : 106; Raios anais : 95 - 112; Vértebras: 117 - 138. This species differs form all other Southern Ocean congeners by having very large head pores and the retrograde origin of the dorsal fin (predorsal distance 27-36.6% SL, free dorsal-fin pterygiophores 6-16; pelvic fin present; anal fin rays 95-112; vertebrae 117-138 (Ref. 75765).
