Inhabit rocky and coral reefs (Ref. 12951); on soft and sandy bottoms. Feeds mainly on mantis shrimps and fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Litters of 1-5 pups; gestation period 10-11 months (Ref. 114953); Caught rarely by the gillnet fisheries operating in shelf waters. Utilized for its meat (Ref.58048).
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). Distinct pairing with embrace (Ref. 205). Brood consists of 1-3 neonates and grow to about 40 cm DW in spring-summer (Ref. 38396).
