Primarily benthic (Ref. 114953). Occurs mainly in the marine environment, but also enters the lower reaches of rivers. Ovoviviparous (Ref. 50449). Males mature by 68 cm TL; born at ca. 20 cm TL. Females produces litters up to 6 pups (Ref. 114953). Minimum depth range from Ref. 121775.
Ciclo de vida ou comportamento de acasalamento
Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas
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).
