Length at first maturity / Taille / Poids / Âge
Maturity: Lm ?, range 64 - ? cm

Likely confined to the inner continental shelf (Ref. 9840), over sandy and mud bottoms (Ref. 30573). Recorded from coastal waters and river mouths (Ref. 45255). Feeds on bottom crustaceans including shrimp, crabs and small lobsters (Ref. 5578). Ovoviviparous (Ref. 50449). Important food fish, the skin and flesh are dried or used to produce leather for purses and bags (Ref. 9840). Caught in very large quantities in the demersal tangle net, bottom trawl and trammel net fisheries. Utilized for its meat, skin (high value) and cartilage (Ref. 58048). It is parasitised on the dorsal skin surface by the monogeneans Dendromonocotyle citrosa, D. colorni, D. ukuthena (Ref. 124058) and D. lotteri (Ref. 124051).
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). Bears 2 young in summer (Ref. 5578). Gives birth to litters of 1-4 pups; born at 18-21 cm WD (Ref.58048).
