Short description

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).

Biology     Glossary (e.g. epibenthic)

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).

IUCN Red List Status (Ref. 115185)

  Vulnerable (VU) (A2bd)

Threat to humans

  Traumatogenic (Ref. 2334)
