Short description

Dorsal spines (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).

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).
