Max length : 86.0 cm WD macho / no sexado; (Ref. 58048)
Demersal on soft bottoms on the continental shelf at depths of 10-140m (Ref.58048). Juveniles (20-22 cm WD) are free swimming. Feeds on prawns, small fishes and crustaceans (Ref. 9840). Ovoviviparous (Ref. 50449). Common by-catch of bottom trawl and beach seine fisheries in the Arafura Sea. Utilized for its meat, skin (high value) and cartilage (Ref.58048).
Ciclo vital y comportamiento de apareamiento
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Born at 20-22 cm WD (Ref.58048).
