The short-tail stingray or smooth stingray (Dasyatis brevicaudata) is a common species of stingray in the family Dasyatidae. It occurs off southern Africa, typically offshore at a depth of 180–480 m (590–1,570 ft), and off southern Australia and New Zealand, from the intertidal zone to a depth of 156 m (512 ft). It is mostly bottom-dwelling in nature and can be found across a range of habitats from estuaries to reefs, but also frequently swims into open water. The largest stingray in the world, this heavy-bodied species grows upwards of 2.1 m (6.9 ft) across and 350 kg (770 lb) in weight. Its plain-colored, diamond-shaped pectoral fin disc is characterized by a lack of dermal denticles even in adults, and white pores beside the head on either side. Its tail is usually shorter than the disc and thick at the base, with a midline row of large thorns in front of the stinging spine and dorsal and ventral fin folds behind. Данное издание...
