Inhabits coastal waters and river mouths (Ref. 45255). Found on the continental shelf. Maximum disc width of about 180 cm. Ovoviviparous (Ref. 50449). Litters of a single pup; born at ca. 33 cm WD (Ref. 114953). Caught very rarely by the demersal tangle net fisheries operating in shelf waters.

Distinct pairing with embrace (Ref. 205).
