Prominent triangular snout. Broadly rounded outer corners of disc. Upper surface brown or yellowish brown, paler toward margins of disc. Lower surface white (Ref. 6902). Few scapular spines. Middorsal row of spines present, but few on tail beyond pelvic fins (Ref. 7251).
Body shape (shape guide): other.
Adults inhabit coastal waters, including estuaries and lagoons (Ref. 12951), mangroves (Ref. 138854) and ascend rivers (Ref. 12951). They feed on tube anemones, polychaete worms, small crustaceans, clams, and serpent stars (Ref. 12951). Ovoviviparous (Ref. 50449). Parturition occurs in July and August (Ref. 27549). Litters of 2-3 pups; gestation 4 months (Ref. 114953).

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).
