A coastal species, which enters coastal lagoons, shallow bays and estuaries (Ref. 81259). Found over sandy and muddy bottoms, sometimes near rocky reefs (Ref. 12951). Feeds on bottom fishes, crustaceans and mollusks. Ovoviviparous, gestation period about 4 months and 4-7 young are produced. Wings marketed smoked, dried-salted, and also used for fishmeal and oil. Harmful to shellfish banks; dangerous to bathers and fishers due to its poisonous spine. Barbed poison spine is a modified denticle that can be 35cm long, shed occasionally and replaced (Ref. 35388). Maximum reported width about 150 cm (Ref. 81259).
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).
