Description

The Sharpsnout stingray is a stingray (Dasyatidae) from shallow coastal and estuarine water of the western Atlantic off the Guianas and Brazil. The species reaches about 60 cm across the disc and has a round to diamond-shaped, flat, brown disc and a long, whip-like tail. Half-buried in sand or mud it searches for molluscs, crustaceans and bottom fish. In its tail it carries a venomous, serrated spine that gives a very painful wound; it stings only in defence when touched or stepped on.
