Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 48.0 range ? - ? cm
Max length : 250 cm WD 雄魚/尚未辨別雌雄; (Ref. 30573)
Ovoviviparous (Ref. 50449). Caught often in demersal trawls, and occasionally by trammel net. Utilized for its meat, but of limited value due to its typically small size (Ref. 58048).
棲息於沿岸淺水區水域與近海淺堆的砂質底部了。 (參考文獻 30573) 卵胎生的.(參考文獻 50449)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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). Gives birth to litters of up to 7 pups; born at 24-26 cm WD (Ref. 58048).印度-太平洋: 紅海到法屬玻里尼西亞,北至日本。
