Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Males court by nipping the female's dorsum. Mating pair orient in a venter to venter position, and the male inserts one or both claspers. The pair usually rests on the substrate, with the female on top of the male. Mating lasts about 30 seconds (Ref. 12951) to 1 minute (Ref. 49562). 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). Size at birth ~60 cm WD. One large pregnant female (~130 cm WD) contained a single late-term embryo 61 cm WD (Ref.58048). 印度-西太平洋: 外海的南非德爾班而且可能地向北延伸到印度，泰國，印尼與中國南部。 也在琉球，琉球群島.(參考文獻 637) 可能地澳洲.(參考文獻 9862)
