Occurs from the intertidal (coastal, inshore) to offshore continental shelves down to 119 m (Ref. 9909, 127960). A carnivorous fish that feeds on large shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Produces 6-10 pups a litter (Ref.114953). Biology little known (Ref. 9909). Utilized where it occurs but details lacking (Ref. 9909).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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).
