Short description Morfología | Morfometría

Diagnosis: A heavily armored stingray lacking a venomous barb; young with large, flat denticles on upper surface, and large juveniles and adults with additional sharp conical thorns and small, pointed denticles (Ref. 5578).

Inhabits the continental shelf area (Ref. 2334), but capable of entering coastal lagoons (Ref. 81259). Found on sand and coral rubble areas near reefs (Ref. 9840), often in caves. Ovoviviparous (Ref. 50449). Due to its difficult handling, it is probably of limited commercial value (Ref. 9840). Its thorn can inflict a painful injury; caught commonly by demersal tangle net fisheries; utilized for its meat, skin (very high value) and cartilage (Ref.58048).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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). Distinct pairing with embrace (Ref. 205).
