: any of numerous large flat cartilaginous fishes (order Rajiformes and especially family Dasyatidae) with one or more large sharp barbed dorsal spines near the base of the whiplike tail capable of inflicting severe wounds
Illustration of STINGRAY
Any of various species (family Dasyatidae) of rays noted for their slender, whiplike tail with barbed, usually venomous spines. Most species inhabit warm seas; a few live in the rivers of South America. Species range in width from 10 in. (25 cm) to 7 ft (2 m). Stingrays eat worms, mollusks, and other invertebrates. These bottom-dwellers often lie partially buried in the shallows, lashing their tail when disturbed. Large stingrays can drive their tail spines into a wooden boat. The spines cause serious, extremely painful wounds that, if abdominal, may be fatal.
