Found inshore and offshore (Ref. 9909). Ovoviviparous (Ref. 50449). Biology little known (Ref. 9909). Utilized where it occurs, but details lacking (Ref. 9909).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

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).
