Description
The pelagic stingray (Pteroplatytrygon violacea) is probably the only fully pelagic member of the stingray family (Dasyatidae). It occurs in open, tropical and warm-temperate waters, usually in the upper 100 metres, and has a deep purple to violet, diamond-shaped disc. On the tail it bears a venomous spine. The ray feeds on coelenterates such as jellyfishes, squid, decapod crustaceans and fish, and is ovoviviparous. The species is regularly taken as bycatch in the pelagic longline and driftnet fisheries for tuna and shark. The disc reaches about one metre across.
