Biologie     Verklarende woordenlijst (bv. epibenthic)

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).
