Dark grey to blackish above and below, ventral mucous pores black (Ref. 5578).

Inhabits the outer shelf and upper slope (Ref. 5578). Rarely caught, probably inhabits hard bottoms that are seldom trawled (Ref. 114953). Feeds on bony fish, crabs and squid (Ref. 5578, Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at 125-135 cm TL, females at 170-190 cm TL. Smallest known specimen at 27 cm TL (Ref. 114953) Probably caught by hake trawlers (Ref. 5578).
棲息於外部的大陸棚與上層斜坡。 (參考文獻 5578) 吃硬骨魚，螃蟹與烏賊。 (參考文獻 5578) 卵生的.(參考文獻 50449) 卵在貝殼上有像觸角一樣的突出。 (參考文獻 205) 可能被鱈魚底拖網捕獲了。 (參考文獻 5578)
