Found in tropical to warm temperate coastal waters, but absent from islands of western Pacific.

Ovoviviparous, gestation period up to one year with 2-6 embryos produced.
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).
