Max length : 78.0 cm TL オス/雌雄の選別がない; (Ref. 114953)
Benthic species of continental shelf on rocky and sandy bottoms to depths of 150 m. It is a night feeder, mainly on small fishes and prawns (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size of males at ca. 47 cm TL, females at ca. 45 cm TL. Species born at ca. 18 cm TL. It is a likely bycatch of gillnet and prawn trawl fisheries (Ref. 114953).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生
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).
