Description

The roughtail stingray is one of the largest whip-tailed rays (family Dasyatidae), reaching a disc width of about 2 metres and a total length of around 3 metres. The angular, rhomboid disc is plain brown to brown-black; rows of rough denticles run over the back and the long, whip-like tail (hence the name), alongside one or more venomous spines. The species lives on sand and mud bottoms of coastal water, the continental shelf and estuaries in the Atlantic and the Mediterranean, and tolerates brackish water. On the bottom it searches, mainly at night, for crabs, crustaceans, molluscs, worms and fish. Through fishing and bycatch it has declined and is assessed as Vulnerable (VU).
