Viviparous (Ref. 50449); gives birth annually to litters of 2-4 pups (Ref.58048). Caught in artisanal and small scale commercial fisheries (Ref. 9997). Utilized fresh for human consumption (Ref. 244); meat and fins, but of limited value due to its small size (Ref.58048).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Viviparous, with a yolk-sac placenta; 2-4 pups per litter. Size at birth 40-43 cm; 54-55 cm TL (Ref.58048). Distinct pairing with embrace (Ref. 205).
