Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0. A giant plain stingray with a broadly pointed snout, small eyes and a round disc; tail short with a long caudal fin and a narrow sting; upper surface covered with denticles (Ref. 5578). Grey-black to brownish or purplish-brown above, white below; rear edges of pelvic fins and tail grey; disc edges black, and sting light (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found on the outer shelf and upper slope (Ref. 5578), on soft bottoms (Ref. 9914) at depths of 275-680 m (Ref.58048). Benthic (Ref. 58302). Feeds on small pelagic fish, eels, crabs, shrimp, lobsters, cephalopods and polychaete worms (Ref. 5578). The specimen taken from a depth of 44 m was caught off Mozambique (Ref. 9914). Its sting is long and can inflict a painful wound if handled. Caught occasionally by demersal longline fisheries in deepwater. Utilized for its meat, but not of a particularly high value (Ref.58048).
