Description

The longtail stingray is a stingray (Dasyatidae) from coastal waters of the eastern Pacific, from Mexico to Peru. The species grows to about 1.5 metres wide and has a flattened, diamond-shaped, brown body with a very long, thin whip tail bearing one or more venomous spines. As a bottom-dweller it often lies half-buried on sand and mud bottoms and searches for crustaceans, molluscs and small fish. The tail spine can give an extremely painful sting wound.
