Biology
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 [733]. Distinct pairing with embrace [17086]. Bears 2 young in summer [536]. Gives birth to litters of 1-4 pups; born at 18-21 cm WD [2539]. Likely confined to the inner continental shelf (Ref. 9840), over sandy and mud bottoms [20218]. Inhabits coral reefs (Ref. 58534). Feeds on bottom crustaceans including shrimp, crabs and small lobsters.
