Description

The longnosed skate is a large, slender skate of the family Rajidae reaching a wingspan of about 1 metre and a total length up to 1.5 metres. The diamond-shaped body, formed by the pectoral fins fused to the head, stands out for a strikingly long, pointed snout; the upper side is grey-brown with dark speckles and pale spots, the underside greyish with dark pores. The species lives on sand and mud bottoms of the continental shelf and slope of the north-eastern Atlantic and the Mediterranean, usually between seventy and over fourteen hundred metres. On the bottom it hunts crabs, shrimps, worms and small fish. It lays eggs in horny capsules and grows slowly; due to fishing it is assessed as Near Threatened (NT).
