Short description Morphology | Morphometrics

Broad, diamond-shaped ray with a very short tail lacking a dorsal spine (Ref. 26938). Snout protruding. Front edges of disk concave. Tail with low dorsal and ventral finfolds and 3 - 4 dark crossbars (Ref. 7251). Upper surface gray, brown, light green or purple with round spots. Lower surface white (Ref. 6902).

Prefers neritic waters of the continental shelf and usually found on soft bottoms. May enter brackish estuaries or hyper-saline lagoons (Ref. 5217). Feeds on fish and shrimps (Ref. 28587); other crustaceans and clams (Ref. 27549). Ovoviviparous (Ref. 50449). Generally marketed salted (Ref. 5217).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
