A large devil ray with a long head bearing short head fins; dorsal fin plain, and pectoral fins with strongly curved, swept-back tips; upper disc densely covered with small, pointed denticles and tail shorter than disc with no spine (Ref. 5578). Dark blue (Ref. 5578), olive-green to brownish above; ventral side white anteriorly, grey posteriorly, with an irregular but distinct line of demarcation (Ref. 11228). No caudal fin (Ref. 5578).
Mostly oceanic, but also in coastal waters. Solitary, sometimes forms groups (Ref. 12951). Feeds on small fishes (Ref. 5578) and planktonic crustaceans (Ref. 9911). Ovoviviparous (Ref. 50449). Litter number 1 (Ref. 12951). Sometimes found stranded in beaches in temperate areas (Ref. 9911). Data on female Max. length from Ref.9256. Commonly caught in tuna gillnet and in harpoon fisheries. Utilized for its gill filter plates (very high value),meat, cartilage and skin (Ref.58048).
Life cycle and mating behavior
Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)
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).
