Descrição breve Morfologia | Morfometria

Broad, diamond-shaped ray with a very short tail lacking a dorsal spine (Ref. 26938). Snout protruding. Front edges of disk concave.

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 Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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).
