Description

The White-edge freshwater whipray is a freshwater stingray (Dasyatidae) from large rivers of Southeast Asia, in the Mekong and Chao Phraya basins. The species grows to about 60 cm wide and has a flattened, oval to diamond-shaped, brown-grey body with a long 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 molluscs, crustaceans and small fish. Through overfishing and habitat loss the species is threatened. The tail spine can give an extremely painful sting wound.
