Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 64.7, range 56 - ? cm
Max length : 75.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 40637); 90.0 cm TL (female); common length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. ); 最大體重: 1.4 kg (Ref. 40637)
Depth range is reported at 55m-1200m in Ref. 9996. Found on the outer continental shelves and upper slopes. Feeds mainly on bottom invertebrates, including shrimps and cephalopods, but also on small pelagic bony fishes (lanternfishes) and other small elasmobranchs. Oviparous, with up to 13 eggs present in the oviducts at one time. Individuals from the Ionian Sea apparently reproduces from end of February to September and eggs are laid between 200 and 600 meters (Ref. 87978). Utilized fresh and dried-salted for human consumption, and for leather.
