Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 9 - ? cm Max length : 49.0 cm ML 雄魚/尚未辨別雌雄; (Ref. 1695); 最大體重: 4.0 kg (Ref. 1695)
In temperate waters, maximum mantle length is 49 cm and up to 4 kg in weight. In the subtropics, maximum mantle length is 30 cm and up to 2 kg in weight (Ref. 1695). Common size: 15.0 to 25.0 cm (West Saharan fisheries; Ref. 275). One of the most important species for cephalopod fisheries in many countries but have been observed in recent years that it is heavily fished, e.g., Mediterranean (Ref. 1695). Also, a highly valued item especially in Japan, Korea, Italy and Spain (Ref. 1695). Maximum depth range from Ref. 114857.
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the female's mantle cavity where fertilization usually occurs. Life cycle: Embryos hatch into planktonic stage and live for some time before they grow larger and take up a benthic existence as adults (Ref. 833).
