Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 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). Fully developed young, size at birth 28 cm (Ref. 37816, Ref.58048).印度-西太平洋: 可能廣泛分佈, 但是已知來自馬爾地夫 (參考文獻 9181) ，塞錫爾群島 (參考文獻 10685) ，新幾內亞，密克羅尼西亞 , 與聖克魯茲與索羅門群島。
