Ovoviviparous (Ref. 5377). Females mature at 37-40 cm TL, males ca. 30 cm TL; born at ca. 19 cm TL. Litters of 1-4 pups after short gestation; born at ca. 19 cm TL (Ref. 114953).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生
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).
