成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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). Gestation about 6 months; 3-7 young produced (Ref. 5578). Size at birth 45 cm WD (Ref. 6677).東大西洋: 葡萄牙與摩洛哥到安哥拉，包括地中海, 馬得拉群島與加納利群島; 然後從沙丹那灣到納塔爾 (南非) 與莫三比克南部.(參考文獻 5578)
